IsTabStop doesn't work as expected?

[Vadimir]

Hi,
I'm using Telerik controls with version 2013.2.724.40, and VS 2010.
In the following code example, I'd like to use tab to navigate only between the 3 TextBoxes. IsTabStop is set to false, but the tab still stops at the RadExpander, is it an expected behavior?

Thanks.
Gong

        <TextBox/>
        <telerik:RadExpander IsExpanded="True" IsTabStop="False">
            <TextBox/>
        </telerik:RadExpander>
        <TextBox/>
    </StackPanel>
</telerik:RadWindow>

Hi Gong,

Thank you for contacting us on that matter. Please note that the IsTabStop property of the RadExpander control is set to False by default.

However, when you tab into the control, the focus goes in the button inside the header. We designed it like this, because you are allowed to expand/collapse the RadExpander using the keyboard. When the focus is in the button, you can press the space bar key and the control will change its status.

In order to achieve your requirement, you can extract the default template of the control and manually set the IsTabStop property of the RadToggleButton control to False. Please, have in mind that by following this approach you will not be able to expand/collapse the control  using your keyboard.

For your convenience I extracted and edited the default template of the control in the attached project. Please take a look at it and let us know if you need any further assistance.
