I have attached a datatable to the grid grouping control.

grdcontrol.DataSource = m_datatable;

When the data on the grid changes, the datatable doesnt get updated. Which property should be set/called to updated the datatable when the grid changes?

Thanks

Hi Navaneeth,

Thanks for using Syncfusion Products.

By default, the grid datas should be updated to underlying datasource as you leave the row (not the cell). If you want the grid values updated as you leave the cell , you can add a CurrentRecordContextChange event handler, and call the Table.EndEdit method for the related table. This will update the underlying datasource if any changes is detected. Also you need to set the Table.TableDirty = true. This property indicates to the engine that it needs to re-categorize elements when the underlying datasource is updated. Below are the codes that shows this task.

private void grid1_CurrentRecordContextChange(object sender, CurrentRecordContextChangeEventArgs e)
{
if(e.Action == CurrentRecordAction.CurrentFieldChanged
|| e.Action == CurrentRecordAction.EndEditComplete )
{
this.grid.CurrencyManager.EndCurrentEdit();
e.Table.EndEdit();
e.Table.TableDirty = true;
}
}

Please try these code and let me know if this helps.

Best regards,
Vinoth
