Hi,
I would like to set the column widths in the ASP.NET GridView control at
runtime
I have tried the following: http://msdn2.microsoft.com/en-us/library/ms178296.aspx
Which uses the following code on a button:
Protected Sub Button1_Click(B yVal sender As Object, _
ByVal e As System.EventArg s)
Try
Dim colWidth As Integer
colWidth = CInt(Server.Htm lEncode(TextBox 1.Text))
If colWidth > 0 Then
For i As Integer = 0 To GridView1.Colum ns.Count - 1
GridView1.Colum ns(i).ItemStyle .Width = colWidth
Next
End If
Catch
' Report error.
End Try
End Sub
But the count on the columns collection returns 0.
I have tried putting the code immediately before and after the databind but
that doesn't work either.
Could someone please tell me what I am doing wrong?
Regards
Steve 5  10285 
If your GridView is creating the columns using the AutoGenerateCol umns=true
then the Columns collection would not have them. http://msdn2.microsoft.com/en-us/lib...w.columns.aspx
"Explicitly declared column fields can be used in combination with
automatically generated column fields. When both are used, explicitly
declared column fields are rendered first, followed by the automatically
generated column fields. Automatically generated column fields are not added
to the Columns collection."

They should be capable to set in autogenerating scenario also if one handles
RowCreated event and sets cell width explicitly in code.

Hello Phillip and Teemu,
THankyou for your repllies.
I tried putting the code in the rowcreated event but that didn't work either.
I am binding to a datatable, whose structure is determined at runtime.
Therefore the autogeneratecol umns has to be set true.
Does anyone have any other ideas as to how I can set the widths?

During the RowCreated event you can loop through the Row.Cells collection (to
get the equivalent of the GridView.Column s collection), e.g.
Sub GridView1_RowCr eated(ByVal sender As Object, ByVal e As
GridViewRowEven tArgs)
If e.Row.RowType = DataControlRowT ype.DataRow Then
dim td as TableCell
For each td in e.Row.Cells
'set the td style to the desired width
Next For
End If
End Sub

Thankyou Phillip. That works perfectly.
I was using the wrong collection ie
For r As Integer = 0 To grdViewEnteredD ata.Columns.Cou nt - 1
grdViewEnteredD ata.Columns(r). ItemStyle.Width = 100
grdViewEnteredD ata.Columns(r). ItemStyle.Wrap = True
Next

I am wondering what is considered a best practice for setting column widths
to fit the data for a DataGridView (.Net 2.0) that was created on-the-fly
from an arbitrary query. What I would probably do is scan the width of each
column for the first couple hundred or so rows and find the largest. (But how
does one convert character counts to field widths in pixels?)
More generally, however, is there a better approach to accomplish this?
