InputPrompt shows without textbox

[Thomas]

I'm trying to get some user input on the very first app launch. However, if I put the call into the main method, the textbox does not show inside the prompt. If I call the same code on a button click event later, everything is fine.

So how do I delay the message dialog until everythig is loaded properly?

[Thomas]

Interesting. Turns out the textbox will only not load when the debugger is attached. Any idea why this might be?

Hello Thomas,

Thank you for contacting us.

I have attached a sample that illustrates how RadInputPrompt can be used in the MainPage's constructor. Please have a look and let me know what I'm missing in order to reproduce the issue that you describe.

Really sorry, I opened the thread in the wrong board. This is an issue with Windows Phone 7.

Hello,
We've set the proper forum and product.
Could you, please confirm that the reported issue is reproducible only at Windows Phone 7?

Yes, this problem only occures in Windows Phone 7 projects but independent of the emulator version deployed to.

Hi Thomas,

Did you try the solution Todor posted here in a Windows Phone 7 context? Let us know if it doesn't work so that we can think of another approach.

Unfortunately, I get an error when pasting this into a WP7 project:

'Telerik.Windows.Controls.RadInputPrompt' does not contain a definition for 'ShowAsync'



A assume this is because Visual Studio 2012 / WP7 does not support async/await out of the box? I have installed Microsoft.Bcl.Async (from nuget), this does not change anything, though.

Hi Thomas,

Thanks for writing back.

The ShowAsync method is only available on Windows Phone 8 as of now.

You will need to use the old Show method with a delegate for the closed event on WP7.
