Denis, the Expand property doesn't work for me. Could you provide a little code that shows how you made it work for you?

I am testing it thus (with AutoResize set to False):
[code]
   Dim Headers As String[] = ["0123456789", "0123456789", "0123456789", "0123456789"]

   GridView1.Rows.Count = 1
   GridView1.Columns.Count = Headers.Count
   GridView1.Columns[0].Expand = True
   For i As Integer = 0 To Headers.Max
     GridView1.Columns[i].Title = Headers[i]
     GridView1[0, i].Text = String(30, "*")
   Next
[/code]

I've tried setting Expand = True after the Column Titles are defined, but it makes no difference.


Charlie, thank you for that code. Setting the column width to -1 does automatically resize the column to fit the data. However, 
I am trying to achieve the behavior that the Expand property is supposed to give: "Return or set if a GridView column 
automatically expands to fit the GridView width." Meaning, as I understand it, similar to AutoResize but for a column other than 
the last column.

I have actually accomplished this by capturing the sum of the column widths within the For loop and then resizing the first 
column mathematically within the Arrange event. It would seem, though, that using the Expand property would be much simpler and 
more sensible.
