I use RadNumericUpDown in many places. My application runs on a PC and on the Microsoft Surface and uses the Windows8Touch theme.
My problem is that whenever the user clicks the + or - button of a RadNumericUpDown the edit control receives keyboard focus which I do not want and cannot seem to prevent. Why is this a problem? Because on the MS Surface, this causes the Windows Virtual Keyboard to appear, immediately obscuring the very control the user is using. The user isn't trying to edit the text box, mind you, just tapping the buttons.
If the the user is only tapping the buttons, it seems that the edit box should not get focus. That should not happen until you actually try to *type* in it. But even if you think it *should* get focus, there at least needs to be a way to prevent it from happening. Yet I cannot find any way short of completely retemplating the control.
Here is what I tried:
1. I tried to setting the entire RadNumericControl's IsEditable property to "False" but this has no effect. Even though the user cannot edit the box, clicking the '+' or '-' button *still* makes the edit control think it is being edited enough to give it focus and force that virtual keyboard to appear
2. Then I tried setting the entire control's "Focusable" property to "False" but that didn't work either. The internal edit control still gets keyboard focus. This is because the Telerik template for the control fails to pass the "Focusable" to its internal edit through TemplateBinding.
The only way I've managed to "fix" this is by completely copying the entire RadNumericUpDown control's template and making it pass "Focusable" to its internal edit via the TemplateBinding. Then I use this template for my RadNumericUpDown and set its Focusable property to false.
But this is serious overkill and my copied template is not using the Telerik Windows8Touch theme that I applied to everything else. So it looks out of place and terrible. It appears I can copy a whole bunch of stuff from the Telerik-installed XAML for that theme, but that's even more overkill than before.
So my questions are these:
1. Am I missing some simpler method here? Does RadNumericUpDown give me a way to get at the internal edit control and prevent it from getting keyboard focus short of copying its entire template?
2. Also, am I correct that it's internal edit should NOT get keyboard focus if you just tap the buttons (at least if it's not editable)?
I am hoping you can point me to an easier way.
