Validation Problem in Rad Numeric TextBox

[Akhil Raj]

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");
        }
    }

thanks friend... but i have a small issue regarding this method. when i delete the letters value reset to "0" correctly but the mouse is blinking...that feel ugly. any other method or any way to restrict that

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

Yes it is not supported with validation group
