Hot tracking in WindowsFormsHost

[Jason]

I'm having a issue with the hot tracking of input controls hosted on a WindowsFormsHost in an WPF application.

The situation is a host that has half a dozen RadTextBoxes on it, stacked vertically. We have our own custom theme which hot tracks the mouse movement by changing the border of the text boxes - much in the same way that the Windows 7 theme does, going from grey to blue when the mouse moves over the control.

If I now move my mouse up and down the form, going back and forth over the text boxes, the border colour changes don't always change correctly. It basically seems a little random. There are no issues with any of this functionality if I'm using the controls in a WinForms applications. 

I'm not sure whether this is a WindowsFormsHost problem not catching the hover events properly, or a problem with hosted telerik controls, but any help would be appreciated. 

Thanks

Hello Jason,

Thank you for your report.

The WindowsFormsHost control have a different mouse events life cycle than standard winforms application (some mouse leave, enter and wheel events are not fired) and we cannot change this behavior. As a workaround I can suggest to change the TextBox border only in case that TextBox contains focus instead of hot tracking.

I hope this will applicable for you application because we are not able to provide solution for this.

Regards,

Thanks. I was guessing it might be an issue with the host control itself
