ggc ColIndex have problem with masterdetail child relation

Hi,
I just resolved it by : ColIndexToField

There is another important issue that I don't know how to deal with. After I updated any changes in particular row and call DS.AcceptChanges then I edit the same row and update it again. But this time I got DBconcurrency error. How to make the data in ggc synchronized with the recent updated dataset and avoid the error?

Thanks and Regards,
Harry

Hi Harisan,

Thank you for your interest in Syncfusion Products.

Please call the EndEdit() method and see it helps to avoid the error.


if(this.gridGroupingControl1.Table.CurrentRecord != null)
this.gridGroupingControl1.Table.CurrentRecord.EndEdit();
this.gridGroupingControl1.CurrencyManager.EndCurrentEdit();


Kindly let us know if you need any further asssitance.

Best Regards,

Hello Jeba,

Thanks for your assist.
I tried it but it still got the same error.
Do I need to write BeginInit somewhere in the module? I need further assist of this matter to resolve it.

Hello Jeba,

I got InvalidCastException error on this line:
Dim dv As System.Data.DataView = cm.List

Unable to cast object of type 'System.Windows.Forms.BindingSource' to type 'System.Data.DataView

How to make this work out?

This is the code to retrieve HeaderText from Haneef:

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

If Not dv Is Nothing Then
Dim col As GridColumnDescriptor = e.TableControl.Table.GetColumnDescriptorAt(e.Inner.RowIndex,e.Inner.ColIndex)
If Not col Is Nothing Then
Console.WriteLine(col.MappingName)
Console.WriteLine( dv.Table.Columns.Contains(col.MappingName) )
End If
End If
End Sub

Thanks and Regards,
Harry
