What has this to do with ASP.NET? It sounds like a sql problem. If you have SQL Sevrer 2005/2008 google for CTE (Common Table Expression), it does exactly what you are looking for.

You can do this in asp.net instead of in sql server
Load all the records and implement a function which you will call recursively to populate your data in any desired way

Read the file, load it into a collection or data table and use that as the data source for the grid view.

You can use TextFieldParser class to do your task.
Something like this,
TextFieldParser fp = new TextFieldParser("mycsv.txt");
fp.Delimiters = {"\t"};
while (!fp.EndOfData)
{
}

In my .net projects I always tend to have an n-tier architecture.
I access the business layer from the presentation layer using references and code.
It seems the object data source does a similar task.
Am I right?
I have seen the object data source in action but it seems to me it does the same thing as what I am doing to access the business layer.
Am I right?
What do you think?
Thanks

So are you saying a client is trying to upload a file to your server or are they trying to download it from your server?

Does this means, you the have the text file in the Server first?

Seems like your using FileUpload Control's FileName property to upload the client file. Use PostedFile property.

Hi, I'm trying to write a program that can access different databases(mainly Sql Server and Oracle).
I've thought about using the Database Application Access Block which seems to be the best way but can't find a decent example of how to use it with oracle. If anyone has any other ideas on how to accomplish this please let me know.
Thanks

What event are you adding the control in? Page_Load
Be careful where the controls are you have to take in to account postback
A good article to read would be on Page Life Cycle

dataGrid1.DataBind();
Response.Clear();
Response.Buffer= true;
Response.ContentType = "application/vnd.ms-excel";
Response.Charset = "";
this.EnableViewState = false;
System.IO.StringWriter oStringWriter = new System.IO.StringWriter();

obj_xl.Workbooks.Add()
obj_xl.Sheets("Sheet1").Select()
With obj_xl
For i = 0 To dt.Rows.Count - 1
For j = 0 To dt.Columns.Count - 1
If IsDBNull(dt.Rows(i).Item(j)) Then
.ActiveCell(i + 4, j + 1) = String.Empty
Else
.ActiveCell(i + 4, j + 1) = dt.Rows(i).Item(j) End If
Next
Next
obj_xl.Dialogs(Excel.XlBuiltInDialog.xlDialogSaveAs).Show()
End With
This was the method i using to export values from data table.
I used some COM components for excel
This worked fine in my system.When i try to run in IIS its showing error as COM file missing

Use This Code:
protected void bttbexcel_Click(object sender, EventArgs e)
{
Response.Clear();
Response.AddHeader("content-disposition", "attachment;filename=FileName.xls");
Response.Charset = "";
Response.ContentType = "application/vnd.xls";
System.IO.StringWriter stringWrite = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter htmlWrite = new HtmlTextWriter stringWrite);
GridView1.RenderControl(htmlWrite);
this.EnableViewState = false;
GridView1.AllowPaging = false;
GridView1.AllowSorting = false;
GridView1.Attributes["runat"] = "server";
Response.Write(stringWrite.ToString());
Response.End();
}
public override void VerifyRenderingInServerForm(Control control)
{
}

I am adding controls to a placeholder on the fly.
I could have any number of controls in there but its usually about 5.
I am adding a label and a textbox to the placeholder.
Now when I loop the placeholder I have the following code:
The textbox value works fine it finds the correct value, but I cant find the label value, why is this?
Any help would be great.
thanks
PlaceHolder placeHolder1 = (PlaceHolder)FindControl("PlaceHolder2");
foreach (Control c in PlaceHolder2.Controls)
{
if (c.GetType().ToString().Equals("System.Web.UI.WebControls.TextBox"))
{
Label lb2 = (Label)c;
TextBox tb2 = (TextBox)c;
SqlCommand cmdinsertliftunion = new SqlCommand("INSERT INTO table(field1, field2) VALUES ('" + lb2.Text + "', '" + tb2.Text + "')", con);
cmdinsert.ExecuteNonQuery();
}
}

The code
if (c.GetType().ToString().Equals("System.Web.UI.WebControls.TextBox"))
{
spessifies that it only goes into the statment if it is an TextBox
try
Label lb2;
TextBox tb2;
foreach (Control c in PlaceHolder2.Controls)
{
if (c.GetType().ToString().Equals("System.Web.UI.WebControls.TextBox"))
{
TextBox tb2 = (TextBox)c;
}
else if(c.GetType().ToString().Equals("System.Web.UI.WebControls.Label"))
{
lb2 = (Label)c;
}
}
}
SqlCommand cmdinsertliftunion = new SqlCommand("INSERT INTO table(field1, field2) VALUES ('" + lb2.Text + "', '" + tb2.Text + "')", con); cmdinsert.ExecuteNonQuery();

Are you adding multiple textboxes and labels to the placeholder?
In that case you need to know witch of the labels og textboxes pair you wan't to insert.

When I use the above code I get the following error:
CS0165: Use of unassigned local variable 'lb2'

foreach (Control c in PlaceHolder2.Controls)
{...
