add OnError to GridDateTimeColumn

[Elliott]

Is it possible to add an OnError ClientEvent to the DatePicker control when a GridDateTimeColumn is opened for Edit?

there are 3 clientevents - OnDateSelected, OnPopupOpening, OnPopupClosing but not OnError

thanks

Hi Marianne,

You could try something, like this:

protected void RadGrid_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)
        {
            if (e.Item is GridEditableItem && e.Item.IsInEditMode)
            {
                GridEditableItem dataItem = (GridEditableItem)e.Item;
                RadDatePicker picker = (RadDatePicker)dataItem["DateTimeColumnUniqueName"].Controls[0];
                picker.DateInput.Attributes.Add("OnError", "DatePickerValidation(),return false");

            }
        }

Best wishes,

what I ended up doing was to check for an invalid entry in the textbox prior to any update

protected void rdpShipDate_SelectedDateChanged(object sender, EventArgs e)
{
    RadDatePicker rdpShipDate;
                         kode
    rdpShipDate = (sender as RadDatePicker);
    if (rdpShipDate.InvalidTextBoxValue.Length > 0)
    {
        return;
    }
