InEditMode

Is it possible to set EmptyMessage in RadGrid1_ItemDataBound Edit Mode for a telerik:GridBoundColumn or GridDateTimeColumn?

Hi ,

Please try the following code snippet to set an empty message on TextBox.
1)GridBoundColumn

ASPX:

<telerik:GridBoundColumn DataField="OrderDate" HeaderText="OrderDate" UniqueName="OrderDate" />

C#:

protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)
    {
        if (e.Item is GridEditableItem && e.Item.IsInEditMode)
        {
            GridEditableItem edit = (GridEditableItem)e.Item;
            TextBox txtBox1 = (TextBox)edit["OrderDate"].Controls[0];
            if (txtBox1.Text == "")
            {
                txtBox1.Text = "Empty";
                txtBox1.Attributes.Add("onFocus", "ClearMessage(" + txtBox1.ClientID + ");return false;");
            }
        }
   }

JS:

<script type="text/javascript">
   function ClearMessage(obj) {
        obj.value = "";
    }
</script>

2)GridDateTimeColumn

ASPX:

<telerik:GridDateTimeColumn DataField="OrderDate" HeaderText="OrderDate" UniqueName="OrderDate">
</telerik:GridDateTimeColumn>

C#:

protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)
   {
     RadDatePicker picker = (RadDatePicker)edit["OrderDate"].Controls[0];
     if (picker.DateInput.DisplayText == string.Empty)
       {
          picker.DateInput.DisplayText = "Empty";
          picker.Attributes.Add("onFocus", "onfocus '"+ picker.ClientID+"'");
       }
   }

JS:

<script type="text/javascript">
    function onfocus(id) {
        id.clear();
   }
</script>

Thanks, but it is not work like telerik:RadTextBox EmptyMessage.
If i save and not change the GridBoundColumn text, EmptyMessage (txtBox1.Text = "Empty") be default text when i save....

Hi,

The ASP TextBox does not have a property EmptyMessage.Hence one suggestion would be to access the txtBox1.Text  in the UpdateCommand,that is,if the value is "Empty", set it as null,before entering it to DB.
