Ah-ha!
I am beginning to understand a little more about how this is supposed to work.
If I am right, probably not, but here goes anyway, the purpose of the dgv in Form1 is to allow for translation/modification of what is in the files from client, to a 'standard' wording.
If I have got that right, you have been doing things backwards!  Sorry, I shouldn't laugh, but it is just the sort of thing I do all the time.
I will wait for your response before going further.

That is correct, with one exception. The only thing I want to accomplish in Form 1 is changing the field headers to a standardized naming convention. In Form 2 I want to standardize the data (but this only needs to be done to certain fields like Doc types). I will explain more to you so we are both on the same page. So we receive files on a daily basis from many different clients. These files contain different information in different columns with different field headers. We use SSIS to get them into our systems however, SSIS breaks every time we run the files through because of the differentiation between field headers and data. So, to get around this I am creating a prototype to standardize all the files which mainly include field headers and data related to some of the fields (i.e. Doc Type, Purpose Type, and so on). So For example, if the field header Doc Type comes in then in form 1 row 1 of the dgv there is a combo dropdown where the user can select the "New" header name. Then the second form needs to include the distinct data for the specific field headers so I can standardize them as well. This second form will activate upon clicking a button. Example:
File 1:
Loan Documentation Type(field name from file) = DocType(new header that will be selected in row 1 of the dgv on Form1)
Low Doc, Full, and No Doc(Doc Types data from file) = L, F, ND(translate doc types to standardized naming convention in dgv on Form 2)
File 2:
Docs(field name from file) = DocType(new header that will be selected in row 1 of the dgv on Form1)
1, 2, and 3 (data from file) = L, F, ND(translate doc types to standardized naming convention in dgv on Form 2)
So the files we get have 100's of loans. For this example, the field Doc Types can have many types (i.e. 50 Full docs, 25 Low Docs, and 25 No docs) which is why I would like to select Distinct values only having to map, in this case, 3 doc types rather then 100.
I am sure I have not explained myself very well in previous posts so please let me know if you need additional information or if you are confused on anything I have said to this point.

Going back to your previous post, you have said that for documentation type a client might have Full Doc, Limited Doc and No Doc; whilst another might have 1, 2 and 3.
Are the options finite? i.e. are there always 3 possibilities for documentation type, and is that the same for all fields? (not necessarily 3, it could be 10, 7 or whatever) The point is are all options (or at least the number of possible options) known to yourselves prior to recieving the file(s). Also will the same client always use the same headings.
On to this post.
I am not 100% on the reason for the multiple dgvs on the mapping form.
In Mapping form, is the purpose of the different dgvs to collate, based on documentation type (dgv1 = full doc, dgv2 = limited doc etc), or to summarise (dgv1 = doctype, with a row for count of full doc, another for count of limited doc etc) with the other dgvs for the other field types.
Is the final objective to just display the data, to stream it to another application or to write it back out to a file and if so what type of file (.csv, mdf, txt)
The point I made previously (about doing it backwards) is that to do anything with the clients data, whether selecting on a field type, collating on a field type, or whatever, you have at that stage to use the clients wording/coding scheme.

No, there could be up to 30+ different doc types. I just used three for this example. Same goes for the other fields we need to map data for. Not all possible data is known until we receive the data and the same client doesn't always give us the same headings or file formats. nothing is considered finite between the data or the headers.
The reason for the multiple dgv's is to have a dgv per field where the data needs to be mapped. So, dgv1 is for Doc Types, dgv2 is for Purpose Types, dgv3 is for Occupancy Types and so on. So the second part of the third paragraph you wrote is correct "or to summarize (dgv1 = doctype, with a row for count of full doc, another for count of limited doc etc) with the other dgvs for the other field types". So the all the dgv's have three columns. The first will be the column that gets populated with the data from the file or the dgv on Form 1(example Full Documentation). The second column is a combo dropdown that contains the new code (F for Full Documentation). The third is a count of how many loans have Full Documentation. After all Doc Types have been recoded, then dgv on Form 1 needs to be updated. For example, Full Documentation is will be updated to F.
Once the dgv on Form 1 has been updated with the new codes from form 2, I will output it to excel for our SSIS (this is done and has been tested).

Hi there.
I have been thinking about this and have made a simple demo of something that I think might work. If you have the time would you give it a quick whirl to see if it might suit.
The demo consists of two forms each having a datagridview and a button, you will be able to work out the names of these controls from the code I will post. I will post the code for the two forms in separate posts, as it would otherwise be a very long post.
This is the test data I have used for the demo and if you could save it as TestData.csv in the directory with the executable for the demo, normally 'application-files-directory\bin\debug'
TestData.csv
Prop, Offer, Docs, Gtee, Figs
house, no, full, none, true
flat, true, part, complete, no
appt, no, no, yes, yes
bungalow, yes, full, no, no
mais, false, yes, no, comp
The code for the first form follows shortly.

Hi Henry, have a good weekend?
I copied the code into two forms but I'm getting an error in the collection code you sent over. The errors I'm getting are:
1. expected {
2. Invalid token '>' in class, struct, or interface member declaration.
The error occurs at:
public class FieldMappingDictionary : Dictionary>
I placed this code outside the public partial class ListEditorForm : Form. Should I place this code somewhere else?
Also, looks like I have a couple of things coming down the pipe today so I may be fairly busy today. Just want you to know incase you don't hear back from me until later today.
Thank you,
Brenton

Yes thanks, very restful.
I am a silly boy.
The errors are because in the reply box if you paste a < the editor replaces it with the html equivalent and the same with >.
If you replace all the '& gt;' with > and '& lt;' with <. all should be well.

Sorry Henry,
That is what I have and is giving the error. There are no '& gt;' or '& lt;' in the code. That must have happend when I copied and paste it into the reply. The error is occuring at public class FieldMappingDictionary : Dictionary>. I tried Dictionary <string, string> but it didn't work.

base[key].Add(value);
}
}
else

// if the key ain't there, add it and a new values list
List<string> list = new List<string>();
list.Add(value);
base.Add(key, list);
}

Incidentally I keep forgetting this.
You could save one step in your overall scheme, if loading the modified data into Excel is not a requirement.
SSIS can read XML directly, and both DataSet and DataTable have a method called WriteXML, which believe it, or not, writes their data (and/or schema) to an XML file.
As I said, if the Excel step is not a requirement, simply write the data to an XML file ready for SSIS.

selectBuilder.Append(key);
selectBuilder.Append(" WHERE Documentation = ");
selectBuilder.Append(val);
string updateQuery = selectBuilder.ToString();
// execute the query here
// you know OleDbConnection, OleDbcommand etc.
// then go round for next mod
//This is where I added the connection
DataTable dFill = null;
String comString = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + Path.GetDirectoryName(Path.GetFullPath(this.dataFile)) + @";Extended Properties=""Text;HDR=YES;FMT=Delimited;IMEX=1\""";
using (OleDbConnection conCSV = new OleDbConnection(comString))
{
conCSV.Open();
OleDbCommand dbCommand = new OleDbCommand(updateQuery, conCSV);
OleDbDataAdapter dAdapter = new OleDbDataAdapter(dbCommand);
dFill = new DataTable();
dAdapter.Fill(dFill);
}
bindingSource1.DataSource = dFill;
dataGridView1.DataSource = bindingSource1;
}
// go round for next key
}
// then do same for next dictionary
}
Do I need to add code for a ShowDialog and capture the full path of the file? Also, the test file is in the debug folder. Maybe it would be easier to hardcode the path of the file in the com string. What do you think?
Thank you,
Brenton

Strictly speaking ProcessMods() was intended merely, to create a copy of the table containing client-data but with your standard column names (See the comments at start of the method). I have left that bit for you to do as I am not sure about the best method for that process. Then it should process all the updates retrieved from MappingForm. You could fill the grid during that operation, but it would slow it down enormously, although it would show progress.
The alternative would be to show the modifications after they are completed. In which case your dgv filling code should either be the very last thing in ProcessMods(), or immediately after the call to ProcessMods() in the MappingForm_Closed event handler (this would be my preference).
For ProcessMods() the parts left to be done are, as mentioned above, copying the data to a new table with proper column names (incidentally I suggested copying so that the original data remains intact, in case of accidents. ), and this bit:
which is immediately above your new dgv fill code.
bwood2020 wrote: Do I need to add code for a ShowDialog and capture the full path of the file?
Yes, for the production version, you probably would. Putting the test data in the debug folder was simply for convenience for what is a demo of a concept.
If you stepped through the query building bit, I hope that you could see that for each of your standardised pieces of data the method builds an update query for each of the versions the client has used. It might turn out that using a query is not the best way to perform this operation, but the point of the exercise is to show that the data required to do the mods, is in a format which will enable the changes to be done fairly easily.
I am currently looking at methods for copying the client data into a table with standard column names.
I'll be back with you shortly. Of course, if you already know how to do this, let me know.

Let me know what you think. Be gentle with me.

If I had more than two brain cells to rub together, I would have written this:
void MappingForm_Closed(object sender, FormClosingEventArgs e)
{
this.docsDictionary = this.MappingForm.DocumentsDictionary;
this.ProcessMods();
this.testDataSet.Tables["ClientData"].WriteXml("ClientTestData.xml", XmlWriteMode.WriteSchema);
this.testDataSet.Tables["StandardData"].WriteXml("StandardTestData.xml", XmlWriteMode.WriteSchema);
}
This should make it easier to compare unmodified and modified data. You should also note that the column names have been modified in the StandardTestData.xml version.

Henry,
This is great! Very well organized and I like the idea of having the ability to contain the integrity of the original data set. I also like the idea of outputting to an xml file as well as comparing both the original data set to the standardized data set.
I did have to modify some of the code you sent over. I had to add <string> to List and <string, string> to the Dictionaries. Let me know if this is not correct and I will go back through and make the recommended changes.
I'm still having problems populating the dgv on form 1. Maybe it's that I have not added some functionality to it. On Form 1 I added a dgv and a button name dataGridView1 and btnGetValue. On Form 2 I added a dgv and a button named dgvDocumentation and btnOK. Am I forgetting anything? I have read through the code and it compiles but just can't pinpoint what's going on.
You’re the man Henry!!!

That sounds right.
I'll go through my designer code to see if I've forgotten to tell you something obvious.

I did tell you that I had added two dgv columns, in the designer, didn't I?
No, you say!
ahem:
private void InitializeComponent()
{
this.components = new System.ComponentModel.Container();
this.dataGridView1 = new System.Windows.Forms.DataGridView();
this.btnGetValue = new System.Windows.Forms.Button();
this.clientColumn = new System.Windows.Forms.DataGridViewTextBoxColumn();
this.standardColumn = new System.Windows.Forms.DataGridViewComboBoxColumn();
this.headersBindingSource = new System.Windows.Forms.BindingSource(this.components);
((System.ComponentModel.ISupportInitialize)(this.dataGridView1)).BeginInit();
((System.ComponentModel.ISupportInitialize)(this.headersBindingSource)).BeginInit();
this.SuspendLayout();
this.dataGridView1.ColumnHeadersHeightSizeMode = System.Windows.Forms.DataGridViewColumnHeadersHeightSizeMode.AutoSize;
this.dataGridView1.Columns.AddRange(new System.Windows.Forms.DataGridViewColumn[] {
this.clientColumn,
this.standardColumn});
this.dataGridView1.Location = new System.Drawing.Point(12, 12);
this.dataGridView1.Name = "dataGridView1";
this.dataGridView1.Size = new System.Drawing.Size(284, 171);
this.dataGridView1.TabIndex = 0;
this.btnGetValue.Location = new System.Drawing.Point(154, 236);
this.btnGetValue.Name = "btnGetValue";
this.btnGetValue.Size = new System.Drawing.Size(75, 23);
this.btnGetValue.TabIndex = 1;
this.btnGetValue.Text = "Value";
this.btnGetValue.UseVisualStyleBackColor = true;
this.btnGetValue.Click += new System.EventHandler(this.btnGetValue_Click);
this.clientColumn.HeaderText = "Client Header";
this.clientColumn.Name = "clientColumn";
this.standardColumn.HeaderText = "Standard Header";
this.standardColumn.Name = "standardColumn";
this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 14F);
this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
this.ClientSize = new System.Drawing.Size(422, 288);
this.Controls.Add(this.btnGetValue);
this.Controls.Add(this.dataGridView1);
this.Name = "ListEditorForm";
this.Text = "List Editor";
this.Load += new System.EventHandler(this.ListEditorForm_Load);
((System.ComponentModel.ISupportInitialize)(this.dataGridView1)).EndInit();
((System.ComponentModel.ISupportInitialize)(this.headersBindingSource)).EndInit();
this.ResumeLayout(false);
}
#endregion
private System.Windows.Forms.DataGridView dataGridView1;
private System.Windows.Forms.Button btnGetValue;
private System.Windows.Forms.BindingSource headersBindingSource;
private System.Windows.Forms.DataGridViewTextBoxColumn clientColumn;
private System.Windows.Forms.DataGridViewComboBoxColumn standardColumn;
Here is the designer code for the first form. Just replace the code in your form1.designer.cs file with it.
I think I'll go for a lie down in a dark room now.

Ha-ha, you have a very good sense of humor. It makes it more fun and adds to my dull and busy day. You are correct sir. You did have that. I am looking through Form 2 and I see I need to add something else to get this to work. One down and one to go. I will follow up with you tomorrow. Thanks again Henry and have a good night!

Hi Henry,
I was extremely busy yesterday but I was able to work on this demo for about an hour. As it turns out I am having difficulties getting the second form to work. I looked through the code again and saw that I was missing a combobox so I added that to the dgv; however this didn't fix the issue. Can you send the designer code for the second form when you get a chance please?
Thank you,
Brenton
