GridDataItem - does not contain a definition

[Austin]

I am trying to pull grid column data in order to call a procedure.  on e.item, bold below, i am receiving error :

Error1'Telerik.Web.UI.GridNeedDataSourceEventArgs' does not contain a definition for 'Item' and no extension method 'Item' accepting a first argument of type 'Telerik.Web.UI.GridNeedDataSourceEventArgs' could be found (are you missing a using directive or an assembly reference?)

here is the C#

protected void Mask_NeedDataSource(object sender, Telerik.Web.UI.GridNeedDataSourceEventArgs e)
        {
            GridDataItem dataItem = e.Item as GridDataItem;
            string @Empl_ID = dataItem.GetDataKeyValue("Empl_ID").ToString();
            RadGridEmpl.DataSource = DataLayer.FirmEmployees.PhoneMask(@Empl_ID);
        }

how can this be fixed?

i figured out it needed to be GridItemEventArgs not GridNeedDataSourceEventArgs.

on to the real issue on a masked column can you make it dynamic?  i have a data source that will change the mask

Hello Austin,

A possible solution is to access the MaskTextBox on ItemCreated event handler and change the Mask and DisplayMask properties. Please check out the following code snippet.

protected void RadGrid1_ItemCreated(object sender, Telerik.Web.UI.GridItemEventArgs e)
{
    if (e.Item is GridEditableItem && e.Item.IsInEditMode)
    {
        GridEditableItem editItem = e.Item as GridEditableItem;
        RadMaskedTextBox mask = editItem["MaskedColumn"].Controls[0] as RadMaskedTextBox;
        mask.DisplayMask = "(###-###-####)";
        mask.Mask = "(###-###-####)";
    }
}

More about accessing cells and their controls could be found in the following help article.
