NullReferenceException on most UXPage XAML files

lawton@xogent.com — Tue, 24 Feb 2015 19:00:32 GMT

After upgrading from 8.0.5000 to 10.0.5000 and persisting through 11.0.5000, most of the UXPage xaml pages in my silverlight app show the following error:

NullReferenceException: Object reference not set to an instance of an object.

I have deleted the obj and bin folders.

I have updated all references.

If I delete a section of the XAML, and then add it back, it will show the design view again.

Any guidance?

UXTextbox ValidationTooltip Exception while using Custom Style

DaveDeSmet — Tue, 16 Jul 2013 11:10:22 GMT

Good day,

I recently got this exception when using ValidationTooltip on a UXTextbox with a custom Style.

In the sample project, I placed 2 UXTexbox controls, one with a custom style and the other without. The control without the style works without any problem and the ValidationTooltip is displayed, however, the control with the style don't.

The style was created using Edit Template -> Edit a Copy. In this sample I haven't modified the style.

When focus on control with the style, I get an exception on IsOpen property.

I have recorded a video showing the steps to reproduce the problem.

Since I was not able to upload mp4 files, I uploaded it to my dropbox (for a better quality, right click on the link below and save):

Note: I've also tested with the UXPasswordBox and there's no problem with this control. However, I haven't tested with the remaining controls. So, please take into account the others.

Please, let me know if there's more information needed.

Regards,

Dave

Hi,

is it possible to have a masked input using UXTextBOX ??? I want to drive user to put only numbers in my textbox.

I have a solution using the keyup property, but i'd like to know if is it possible to specify directly while instancing the control.

Thank you.

P.S. is it possible to have (for each control) something like a whitepaper with all the properties, methods, and so on ??? Your controls are fantastic but we are very unhappy of your documentation ....
