RadInputManager Validation IsRequired white space

[Jacob]

Hi,

Can I make RadInputManager validation to triger also when user inputs space char as asp:RequiredFieldValidator does ?

Hello Jacob,

One possible option is to wire the OnValidating client-side event of the relevant setting and validate the value there:

<asp:ScriptManager runat="server">
</asp:ScriptManager>
<script type="text/javascript">
    function Validating(sender, args)
    {
        if (args.get_input().get_value() == " ")
        {
            args.set_isValid(false);
            args.set_cancel(true);
        }
    }
</script>
<telerik:RadInputManager runat="server" ID="RadInputManager1">
    <telerik:TextBoxSetting BehaviorID="TextBoxSetting1" Validation-IsRequired="true"
        ClientEvents-OnValidating="Validating">
        <TargetControls>
            <telerik:TargetInput ControlID="TextBox1" />
        </TargetControls>
    </telerik:TextBoxSetting>
</telerik:RadInputManager>
<asp:TextBox ID="TextBox1" runat="server">
</asp:TextBox>

I hope this helps
