I have an issue with a datagrid 'losing' it's contents when I add a tablestyle to it.

I have one simple line:

MyDataGrid.TableStyles.Add(MyTableStyle)

When run in debug and put a break point on this line, I can see the contents of the datagrid, i.e. MyDataGrid (0,0) returns a value.

However as soon as I run this line and try doing the MyDataGrid(0,0) again I get the following error:

Run-time exception thrown : System.ArgumentOutOfRangeException - Specified argument was out of the range of valid values.
Parameter name: rowIndex

Has anyone else had this problem?
Any ideas what is going on?

Kindly Try this one, It worked for me. Call drawGrid before binding data(Sample for Datareader, Delete lines with to use dataset)

#Region "Declarations"
   'Grid
   Dim pDatagrid As DataGridTableStyle = New DataGridTableStyle()
   Dim Col1 As DataGridTextBoxColumn = New DataGridTextBoxColumn() '*
   Dim Col2 As DataGridTextBoxColumn = New DataGridTextBoxColumn() '*
   Dim Col3 As DataGridTextBoxColumn = New DataGridTextBoxColumn() '*
   'Grid Table
   Dim pTable As New DataTable("TeamPlayers") '*
   Dim pRow As DataRow '*
#End Region

Sub DrawGrid()
 DataGrid1.TableStyles.Clear()

 With pDatagrid
  .MappingName = "TeamPlayers"
  .AlternatingBackColor = Color.LightGoldenrodYellow
  .GridLineColor = Color.Black
  .ForeColor = Color.Blue
 End With

 With Col1 '*
  .MappingName = "Players" '*
  .HeaderText = "Player" '*
  .Width = 260 '*
  .NullText = "No Data Avail" '*
  pDatagrid.GridColumnStyles.Add(Col1) '*
 End With '*
 DataGrid1.TableStyles.Add(pDatagrid)

End Sub


I hope this will help you

I managed to fix this thanks to some advice I received from another forum. I needed to reset the datagrid's datasource after applying the tablestyle.

Thanks for taking the time to help, it's greatly appreciated.
