Pokušavao sam sinoć nešto u vezi sa tim, ali mislim da je u .NET Framework-u 1.x to nemoguće. Ipak nisam 100% siguran. Potraži u MSDN-u metod DataGridColumnStyle.GetPreferredSize, pa ćeš možda preko njega moći to da uradiš, ali jedino 'pešaka'. Znači da petljom prođeš sve zapise, nađeš najširi i prema njemu podesiš širinu kolone.

hvala na pomoci

Evo malo coda :


Public Sub AutoSizeTable()
Dim numCols As Integer
numCols = DS.Tables(0).Columns.Count
Dim i As Integer
i = 1
Do While (i < numCols - 1)
AutoSizeCol(i)
i = (i + 1)
Loop
End Sub
Public Sub AutoSizeCol(ByVal col As Integer)
Dim width As Single
width = 0
Dim numRows As Integer
numRows = DS.Tables(0).Rows.Count
Dim g As Graphics
g = Graphics.FromHwnd(DataGrid1.Handle)
Dim sf As StringFormat
sf = New StringFormat(StringFormat.GenericTypographic)
Dim size As SizeF
Dim i As Integer
i = 0
Do While (i < numRows)
size = g.MeasureString(DataGrid1(i, col).ToString, DataGrid1.Font, 500, sf)
If (size.Width > width) Then
width = size.Width
End If
i = (i + 1)
Loop
g.Dispose()
DataGrid1.TableStyles(0).GridColumnStyles(col).Width = CType(width, Integer)
End Sub
