Hi,

I have a RadGrid with EditFormType="WebUserControl". In my usercontrol I have a custom validator to check the value and allow to update or not.

My problem is that  _dataItem is null on the CustomValidator_ServerValidate event.
I try this code :

public object DataItem
{
    get
    {
        return (object)ViewState["DataItem"];
    }
    set
    {
        ViewState["DataItem"] = value;
    }
}

But even with ViewState DataItem is always null (in CustomValidator_ServerValidate event).

Have you a solution ?

Hello Mikael,

Generally, the DataItem of the GridDataItem instance is present only when binding the item, for example ItemDataBound event handler. You can try to add this field name to the DataKeyNames collection and then access it during the validation logic in server-side:
http://docs.telerik.com/devtools/aspnet-ajax/controls/grid/rows/accessing-cells-and-rows#accessing-raw-field-data-and-key-values

You can get the currently edited grid item from the UserControl page using this.NamingContainer as GridEditableItem.
I hope this will prove helpful.

Regards,
