hi,
  In edit form template of gridview i used radnumerictextbox. I validate the value using requiredfiled validator. My initial value is 0 and i set in the required field validator. How can i handle empty text. When i delete values in textbox and press update the validator not captured the error and i got the old value before the textbox used.

How can i hablde this issue?

Hello,

Try the following work-around and see whether it helps.

aspx:
 
  <FormTemplate> 
        <asp:Button ID="Button2" runat="server" Text="Update" CommandName="Update" /> 
        <telerik:RadNumericTextBox  ClientEvents-OnBlur="OnBlur" ID="tbUnitPrice" runat="server" Value="0" EmptyMessage="0"
        </telerik:RadNumericTextBox> 
 
        <asp:RequiredFieldValidator ID="RequiredFieldValidator1" ControlToValidate="tbUnitPrice" 
            ErrorMessage="This field is required" InitialValue="0" runat="server" Display="Dynamic"
        </asp:RequiredFieldValidator> 


javascript:
 
    function OnBlur(sender, args) { 
        if (sender.get_value() == "") { 
            sender.set_value("0"); 
        }     
    }

This doesn't seem to work if we have validation group involved.
