radgrid commanditem performinsert not firing

[Soni]

i have created radgrid as picture in attacment
my goals is to create empty radgrid then add the row with RadGrid Automatic Operation(performinsert())
but i can't fire the method anyway, when i click insert like attachment's picture nothing happen

i bind the grid with OnNeedDataSource with DataTable(without sqldatasource like others online tutorials)


here's the code

public void rg1_NeedDataSource(object source, Telerik.Web.UI.GridNeedDataSourceEventArgs e)
       {

           DataTable temp = new DataTable();
           temp.Columns.Add("Display", typeof(string));
           temp.Columns.Add("Value", typeof(string));
           rg1.DataSource = temp;
       }

public void rg1_ItemCommand(object source, Telerik.Web.UI.GridCommandEventArgs e)
       {
           if (e.CommandName == RadGrid.PerformInsertCommandName)
           {
               GridEditableItem item = e.Item as GridEditableItem;
               rg1.MasterTableView.PerformInsert(item);
               rg1.Rebind();
               //RadTextBox rbrbrbrb = new RadTextBox();
               //rbrbrbrb.Text = "tes";
               //radAP4.Controls.Add(rbrbrbrb);

           }
       }

Hi Soni,

Note that automatic Insert/Delete/Update is only possible for Declarative DataSource. In case of NeedDataSource you can explicitly write the queries for Insert/update/Delete operations. You can take a look into the following documentation

Insert/Update/Delete at Database Level with Queries
