Hi David,

To add a column which is not bound to the datasource, you need to add the column as an unbound column.

To add an unbound column see the following code,


Then to provide values to the bounded column by handling the QueryValue event. Please see the code:

this.gridGroupingControl1.TableDescriptor.QueryValue += new FieldValueEventHandler


private void unboundField_QueryValue(object sender, FieldValueEventArgs e)
int RecordIndex

if (e.Field.Name == "print" && RecordIndex>=0)

e.Value= "value";

Please let me know if this helps.
