Bound datagridvewview column ordering confusion

Matthew Cuba3-Oct-07 7:39

Hello,

So, I've got a DataGridView that is bound to some data in a DataTable. I only show a subset of the columns and additionally have two non-bound columns in the DataGridView.

I've attempted to set the column ordering via the DisplayIndex property to no avail.

If I attempt to set the DisplayIndex for each in ascending order such as:

column0.DisplayIndex = 0;
column1.DisplayIndex = 1;
.
.
.
column9.DisplayIndex = 9;

the columns don't order correctly. They end up showing up as follows (numbers are the order that I specified them in):

0, 1, 2, 6, 8, 4, 7, 3, 9, 5

The two non-bound columns are 6 and 8 and are DataGridViewImagaColumns. The others are text columns.

Has anyone else had such a problem and solved it? I saw some similar questions asked in my google searching but didn't see a solution to this. I wonder if it is a bug or perhaps I'm just missing something here.

Thanks for you help,
Matt

Hey,

I don't know if there is a reason your changing the order via the DisplayIndex, or what your using to write your code, but if you right click on the datagridview and go edit columns, then you can change the order by moving them up and down in the list(In Visual Studio .NET 2005).

Hope that helps, if not disregard.

Saving an self painted image from a pictureBox

Hello,

I'm programming a little music helper and use the System.Drawing class, to draw the staves and notes on a PictureBox. I want to save that as Image, but all my attempts failed. Of course I used Google to find the answer and I found a advice. It says that I have to draw my things on a Bitmap first and save that. But How do I draw something on a Bitmap with Graphics?

I'm looking forward to your answers.

Best regards

Drawing anything in a Bitmap using a Graphics object is very easy. You will need to first create one bitmap object and use it for initializing graphics object.

Once you get one graphics object created using FromImage method, you may draw anything in this graphics object and it will be drawn on bitmap also.

At last you may save the bitmap using Save method of bitmap object.

Such as-

----------Start Code----------------

Bitmap a = new Bitmap(400, 300);

Graphics g = Graphics.FromImage(a);

g.DrawLine(Pens.AliceBlue, 0, 0, 100, 100);

a.Save(“C:\MyFile.jpg”);

--------------End Code--------------

I hope this helps Smile | :)

If you mean to ask which is the default development language in .NET, then there isn't one. Out of the box, you can develop in C# or VB.NET (the compilers are included with the .NET runtime) and you can download/choose other languages as you see fit.

Deja View - the feeling that you've seen this post before.

EDIT: the XML isn't showing (download here: http://rapidshare.com/files/59995138/test.xml.html)

I have this XML.
I use the code below to open the XML and treat it as a DataSet and view it in a datagrid.

<code> try
{
dataset = ReadXML(szPassword);
dataGrid1.DataSource = dataset;
dataGrid1.DataMember = "principal";
}
catch (Exception ex)
{
MessageBox.Show(ex.ToString());
}</code>

put this in a different class, if you wish.

<code> public DataSet ReadXML(string szMyXMLfile)
{
DataSet ds = new DataSet();
try
{
ds.ReadXml(szMyXMLfile);
return ds;
}
catch (Exception ex)
{
throw new Exception(ex.Message);
}
}</code>

I want to treat The DataSet, NOT the XML, (change values, modify fields) through code.
How Can I get these fields from the dataset's ADM name into an ArrayList? (look at picture) http://bayimg.com/eaHdKAaBg
<code>store.all.admin
launch.more
launch.all
user-management
Direction</code>

Thanks for your replies.

EDiT: here's my current search routine
<code>
foreach(DataRow dr in dataset.Tables["principal"].Rows)
{
if (dr["name"].ToString()=="ADM") // "ADM" (for example)
{
foreach(DataRow dr2 in dataset.Tables["grant"].Rows)
{
textBox1.Text += dr2["name"].ToString() + Environment.NewLine;
aPermissoes.Add(dr2["name"].ToString());
}
if (textBox1.Text.Length>=2) textBox1.Text = textBox1.Text.Remove(textBox1.Text.Length-2,2);
}
}
</code>

You can't. NTFS doesn't track who makes changes to what files or deletes a file.

The only way to get the information on a Created file is to get the owner of the file from the files Security Descriptor.
