I'm sorry but I don't understand your question.

Could you please rephrase it and include details on what you are having problems with?

Also, could you post the ASP markup for the GridView?

Yes you can create gridview at runtime.
Here is just sample code how to add bound couln and template column

BoundField Column1 = new BoundField();

Column1.DataField = "Name";

Column1.HeaderText = "Name";

GridView1.Columns.Add(Column1);

TemplateColumn

TemplateField ckhColumn = new TemplateField();


ckhColumn.HeaderTemplate = new GridViewTemplate(ListItemType.Header, "CheckBox Column");

ckhColumn.ItemTemplate = new GridViewTemplate(ListItemType.Item, "some data");

GridView1.Columns.Add(ckhColumn);

If you choose to do this (which I do not recommend if you are new to ASP.NET)...and you want to have your LinkButtons work properly, you will need to place this code in the Page Init event, and you will need to make sure that your TemplateFields to gobble up the LinkButton click events...

You should look over this quick over view of how to use dynamic controls in asp.net to get an idea of what is involved with dynamic controls.

If you are new to ASP.NET I strongly recommend against dynamically creating your TemplateFields because if the number of TemplateFields changes between postbacks you could run into issues....also you need to have a firm grasp on how events and the ASP.NET life cycle or else you will run into problems.

I recommend adding your TemplateFields into your GridView ASP markup. This will save you a lot of headaches.

So, you want to use the same GridView to display different tables.....

I'm just curious, before we begin down this path...
Why don't you just make a GridView (as you have here) for each table...and set the Visible property of the GridViews to true or false...accordi ng to the table the user is working with?

[saifulhaque]

How can set visible property true and false for diffrent tables,How i can set Header text for each field.If i didn't change Header text field name will be header text Can you give an example.

If i get the answer of previous one that is also better to me.

[Frinavale]

You can change the properties during the RowDataBound event.

At this point the data has been bound to the row....you can access the type of row being bound to determine the course of action to take.

-Frinny

[saifulhaque]

Can you give an example for changing Header Text of columns at run time?

[Frinavale]

Hmm, normally I would recommend that you try something yourself first and post what you have so that we can work from there...but here is an example of what you're looking to do.

(vb.net)

Protected Sub MyGridView_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles MyGridView.RowDataBound
  If e.Row.RowType = DataControlRowType.Header Then
    Dim link As LinkButton = Ctype(e.Row.FindControl("link"), LinkButton)
    If link IsNot Nothing
      ' do stuff with the "link" in the header
    End If
  End If
End Sub
