GridGroupingControl: Refresh after row changed from code

[Administrator]

Hello !
I have the code below that set (null) value to nullable fields for underlying data row.

But the changes appear only after some actions from user (changing sizes, collapse or expand child tables e.t.c.)
gridGroupingControl1.Refresh() has no effect.
Please help me, how to show changes immediately ?

Thanks.

Code:
if (info.record != null && info.field != null)
{
DataRowView rv = info.record.GetData() as DataRowView;
if (rv != null && rv.Row.Table.Columns[info.field.MappingName].AllowDBNull)
rv.Row[info.field.MappingName] = DBNull.Value;

}

Where are you trying to do this code? In Form_Load,a button handler, or in some other event?

It is handler of context menu.

Is this a GridGroupingControl with nested tables? If so, how are you identfying the info.Record object you are trying to change?

If you place a stop in your code that sets things to null, is it being hit? And does infor.Record hold the values you expect?

Some things to try would be to set tableDirty.

this.gridGroupingControl1.Table.TableDirty = true;
this.gridGroupingControl1.Refresh();

or to call

this.gridGroupingControl1.Table.InvalidateCounterTopDown
