RadInputManager Error Message disappears

[DW Web Team Member]

Hi,

As you can see from the code, the text box is required to have a value. The text box has no value. I click on the button first time everything is working correctly and I have the "Error!" message inside the textbox. When I click on the button second time without changing anything, the text box still has the error style but the message disappears. And if I have EmptyMessage set up, it would appear instead of the error message. How can I make the error message stay?
Thank you

<asp:TextBox ID="txtTest" runat="server" />

    <telerik:TextBoxSetting BehaviorID="bhTest" ErrorMessage="Error!"
        Validation-IsRequired="true" Validation-ValidationGroup="ValidationSummary1">

            <telerik:TargetInput ControlID="txtTest" />
        </TargetControls>

Hello,

I cannot reproduce the described problem with the provided markup. Can you confirm it is sufficient to replicate the behavior? Also please specify on what browsers are you observing the undesired behavior and what version of the controls are you using.

Best wishes,

I am using the Q3 2009 version of the RadControls and IE 8.

Hi Tatiana,

In that case please update to the latest release, as the problem does not exist with it.

All the best,
