How to perform the editing successfully in GridControl?

To perform editing it is necessary to add a PrimaryKeyColumn to the TableDescriptor . Please refer the below code snippet which illustrates this:

C#

this.GridGroupingControl1.TableDescriptor.PrimaryKeyColumns.Add("Col1");

VB

Me.GridGroupingControl1.TableDescriptor.PrimaryKeyColumns.Add("Col1")

Adding PrimaryKeyColumns to the Child table:

C#

GridTableDescriptor childtd1 = this.GridGroupingControl1.TableDescriptor.GridRelations[0].ChildTableDescriptor;

childtd1.TableDescriptor.PrimaryKeyColumns.Add("Column name");

VB

Dim childtd1 As GridTableDescriptor = Me.GridGroupingControl1.TableDescriptor.GridRelations(0).ChildTableDescriptor

childtd1.TableDescriptor.PrimaryKeyColumns.Add("Column name")
