UnBound CheckBoxColumn Child grid

HI, I have a been trying different way to get around a slow checkbox issue. Now I am using an unbound Checkbox in a heirarchy Grid but I can''t find a way to programmatically set the Child''s checkbox value without modifying the datasource directly. I have implemented the unbound Checkbox according to the KB on how to add an unbound checkbox I found on this site. Currently for the Parent I do this: For I = 0 To GridGroupingControl1.TableControl.Table.Records.Count - 1 MyWellRecord = GridGroupingControl1.TableControl.Table.Records(I) Dim WellRecordIndex As Integer = Me.GridGroupingControl1.Table.PrimaryKeySortedRecords.IndexOf(MyWellRecord) checkboxvalues(WellRecordIndex) = True Next But I can''t find a way to get the PrimaryKeySortedRecords.IndexOf for the Child Table. Please Help This is a major stumbling block us. Regards, Chris Wescott

Hi Chris, This can be achieved by using the following code snippet. int RecordIndex =this.gridGroupingControl1.Table.RelatedTables["RelationName"].PrimaryKeySortedRecords.IndexOf(e.Record); Here is the sample which explains how to add unbound checkbox column for a parent and child table. Let us know if this helps. Best regards, Madhan
