Hi Sumudu,
Thanks for using Syncfusion products.
In order to add new record when PushButton in last column of the AddNewRecord is clicked, EndEdit() method can be used. Please make use of the below code.
Code Snippet
//event hookup.
this.gridGroupingControl1.TableControlPushButtonClick += new GridTableControlCellPushButtonClickEventHandler(gridGroupingControl1_TableControlPushButtonClick);
void gridGroupingControl1_TableControlPushButtonClick(object sender, GridTableControlCellPushButtonClickEventArgs e)
{
//to add record on button click.
this.gridGroupingControl1.Table.EndEdit();
}
