I have a page with a NumericTextBox with EmptyMessage set. This works and the EmptyMessage text is shown when the page loads. There is a problem when you go to a different page and then click the browser back button to return to the original page. In this case the EmptyMessage text is not shown. I tried this in IE8 and Chrome and get the same results in both. Is there a way to make this work?
Here is the code:
Here is the code:
<asp:TextBox ID="textExistingAssets" MaxLength="10" Width="100" runat="server" /><asp:RequiredFieldValidator ErrorMessage="Field is required" ControlToValidate="textExistingAssets" Display="Dynamic" EnableClientScript="False" runat="server" /><telerik:RadInputManager runat="server"> <telerik:NumericTextBoxSetting Type="Currency" DecimalDigits="0" MinValue="0" MaxValue="2000000000" EmptyMessage="$"> <TargetControls> <telerik:TargetInput ControlID="textExistingAssets" /> </TargetControls> <Validation IsRequired="false" /> </telerik:TextBoxSetting> </telerik:RadInputManager>6 Answers, 1 is accepted

Hi Patrick,
I was not able to reproduce the issue. I prepared a small sample and attached it to this forum post. Could you please give it a try and let me know how it differs from your real setup?
Kind regards,

Hi Kostadin,
Thanks for the sample code. I was not able to reproduce the problem with your sample code. But I did some further testing and found that the problem occurs when the clicked button redirects to another page in the server click event. I've modified your sample to show the problem and pasted it below. Here are the repro steps:

I've modified your sample to show the problem and pasted it below. Here are the repro steps:
- Load page, note that "$" appears in the textbox.
- Click the button to go to Google.com
- Click the browser back button.
- The "$" text is no longer in the textbox.

Hello Patrick,
The issue is reproducing only in IE. As a workaround you could use the following JavaScript:

I tried this but I'm getting an error for updateValueForAllTargetInputs. The browser is saying this is not a valid method. I can't find any documentation on this method. Is it in a newer version of the Telerik controls?

I upgraded to the latest version of the Telerik controls and now it is working as expected. The older version of Telerik that I was using must have had a defect that has since been fixed. This issue is now resolved. Thanks!
