Hello,
I using Grid Grouping Control in my form with parent child Relationship with Datasource As datatable.
when user Update Cell Value in Child table i update datasource and rebind datasourc to  ggc.

After updating cell value in child table,when I leave the cell using mouse click,I got object reference error.

By tabbing or using keys,there is not any problem.

Please suggest me any solution

Suggestion:
Please make use of the ForceImmediateSaveValue property. It may help you to update the values of the columns while leave the current cell.

Code Snippet:

//Used to update the cell value immediately upon changing the value.
this.gridGroupingControl1.TableDescriptor.Fields["ColumnName"].ForceImmediateSaveValue = true;
this.gridGroupingControl1.GetTableDescriptor("ChildTable").Fields["ColumnName"].ForceImmediateSaveValue = true;

Please let us know if you have any other concern.
