Hello,

I have the following FormTemplate that I am using to update/insert. However, I am having issues attempting to read the values of the control. Can someone please advise on how to read controls best, so that I can add these values to the SQL database? I cannot automatically add the values due to having some conditions before adding. Thank you!

                <FormTemplate>

Hi Salman,

The ItemCommand event of the Grid for the EditCommand is triggered just after the Edit button is clicked and the controls inside the template are still not available at this moment. In order to apply any changes to the controls inside the Grid edit form template, you have to do it in the ItemDataBound event, by checking if the current item is in EditMode. You can find more details on the matter here:
https://docs.telerik.com/devtools/aspnet-ajax/controls/grid/rows/accessing-cells-and-rows#accessing-controls-in-editinsert-mode

For example:
protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)
{
    if (e.Item is GridEditableItem && e.Item.IsInEditMode && !(e.Item is GridEditFormInsertItem))
    {
        GridEditableItem editFormInsertItem = e.Item as GridEditableItem;
        RadTextBox ddValue = (RadTextBox)editFormInsertItem.FindControl("txtDescription");
        string sValue = ddValue.Text;
    }
    else if (e.Item is GridEditFormInsertItem && e.Item.IsInEditMode)
    {
        GridEditFormInsertItem insertFormInsertItem = e.Item as GridEditFormInsertItem;
        RadTextBox ddValue = (RadTextBox)insertFormInsertItem.FindControl("txtDescription");
        string sValue = ddValue.Text;
    }
}
