ReadOnly RadNumericTextBox not firing OnFocus()

[Thad]

Hello,

When I set ReadOnly=true on a RadNumericTextBox via markup, the client event OnFocus() does not fire.

<telerik:RadNumericTextBox CssClass="FarmSerialNumber" ID="rntbAcreageFarmSerialNumber"
    runat="server" Width="40px" Value='<%# DoubleFromDb(Eval("FarmSerialNumber"), true) %>'
    ReadOnly='<%# DoubleFromDb(Eval("FarmSerialNumber"), true) != null %>' MinValue="1">
    <NumberFormat DecimalDigits="0" GroupSeparator="" />
    <IncrementSettings InterceptMouseWheel="false" />
    <ReadOnlyStyle ForeColor="Gray"></ReadOnlyStyle>
    <ClientEvents OnValueChanged="radNumericTextBox_ClientValueChanged" OnFocus="acreageControl_ClientFocus" />
</telerik:RadNumericTextBox>

The documentation does not mention that this doesn't fire when it is readonly.
http://www.telerik.com/help/aspnet-ajax/input-client-side-onfocus.html

To ensure that this is not a problem with the <input> element, I added this and it works fine.

<input type="text" onfocus="alert('Yup.  Works')" readonly="readonly" />

Is this a bug or by design?

Thanks!
Thad

Hello Thad,

By design focus and blur client events are not fired when the Input is ReadOnly.

Hi Vasil,

I would highly suggest reconsidering this design decision.  This is not a limitation of the html INPUT or asp.net TextBox control, so it should not be a limitation of the RadInput control.  I can come up with many perfectly valid reasons why someone would want JavaScript code to fire off when a ReadOnly control gets focus.

Unfortunately, it sounds like the only workaround I have is to have two controls instead of one and display a readonly asp:textbox if there is a value already entered and display the telerik:radnumerictextbox if no value has been entered.

Um, I keep getting an "Oops..." message when posting a reply, but it's posting anyway.  Sorry for the multiple posts.

Hello Thad,

The design is such because the control is actually not in focus, you see that it's styling remain ReadOnly, and its value is the display value and so on.

However you see the cursor because the visible HTML input is focused. If you want to check if it is visible you could attach a handler to the onfocus DOM event of the visible input element.
For example this code should work for you:

<script type="text/javascript">
  function focused(sender, e)
  {
    alert("focused");
  }
</script>
<telerik:RadTextBox runat="server" onfocus="focused(this,event)" ReadOnly="true">
</telerik:RadTextBox>

Hi Vasil,

That is a very acceptable workaround.  Thank you!

Is it possible to at least add a note into the documentation regarding the fact that the control differs from the base controls?  Or a sample into the troubleshooting/application scenarios?  That would be very useful.

Thanks!

Hi Thad,

Thank you for the suggestion, we added a note in the events section of the help about the Input, It will be visible after the next upload of the site.

Best wishes,
