ColumnHeader text of selected cell had problem if visible column removed

[harisan]

Hello,

I tried this suggestion in other forum and it did not work fine if there are visible column(s) removed.
Please advise me how to get it worked correctly with Column indexing.

Dim Field As Integer = e.TableControl.TableDescriptor.ColIndexToField(e.Inner.ColIndex)
MsgBox(e.TableControl.TableDescriptor.Columns(Field).HeaderText)

Thanks and Best Regards,
Harry

Dear SriRajan,

Thanks for your assist.
It works fine with your sample since it is use single table. It didn't work as expected if there is childtable relation as in our sample project.

Kindly check out the file attached in Concurrency error in GridGroupingControl by Haneef forum, hope that you will understand and find out how to fix the bug?

Best Regards,

Hi Srirajan,

I hope you will check out the sample code so that you can figure out the colindex problem. I have file submitted in Subject: Concurrency error in GridGroupingControl

Haneef proposed a code that seems good but I got InvalidCastException

Private Sub gridGroupingControl1_TableControlCellClick(ByVal sender As Object, ByVal e As GridTableControlCellClickEventArgs)
Dim cm As CurrencyManager = e.TableControl.Table.GetCurrencyManager()
Dim dv As System.Data.DataView = cm.List --> error on this line

So far the problem have not been resolved yet.
Pls advise.

Thanks and Regards,
Harry

Hi Harry,

You can use the GetHeaderColumnDescriptorAt to retrieve the HeaderText and see if it avoids the error.

Private Sub gridGroupingControl1_TableControlCellClick(ByVal sender As Object, ByVal e As GridTableControlCellClickEventArgs)
Dim style As GridTableCellStyleInfo = CType(Me.gridGroupingControl1.TableModel(e.Inner.RowIndex, e.Inner.ColIndex), GridTableCellStyleInfo)
Dim table As GridTable = style.TableCellIdentity.Table
Dim column As GridColumnDescriptor = table.GetHeaderColumnDescriptorAt(style.TableCellIdentity.ColIndex)
MessageBox.Show(column.HeaderText)
End Sub

Regards,
Jeba.
