I was useing the demo version of the control for 8.1 and all was working fine.  I purchased 8.2 and replaced the files associated to the ASPx Spell Checker control and then I noticed the problem.

I am using the container spell checking option, really nice feature, but when the controls are checked, after each control it displays the message Spell Check Is Complete (OK Dialog) then continues to the next control, after that control it again displays the complete message and again repeats the process.

If I have 10 textboxes on the screen, I end up with 10 ok prompts.

My controls are nested within an update panel and each control has a textbox water mark extender applied and some have a masked edit.  I removed the wark extender and the mask edit extenders, but the problem still occurs.

I then took the controls out of the update panel and it works as expected.  In 8.1 it worked while the controls were in the update panel.

So how do we correctly use the spell checker control, using the container method, with the controls in an update panel or is this a bug that was introduced with 8.2?

Well I did some more testing, and started two demo projects using the 8.1 version and the 8.2 version. I started with using the exact code form the demo on this site for the spell checker. It worked as expected in both cases.

I then added a standard asp.net textbox control to the same form and when doing a spell check in the 8.2 project the spell checker got hung in the loop and never completed.  In 8.1 it works fine with asp.net textbox controls.

So the problem is in 8.2 and it stems from it trying to check the asp.net textbox control.

I am not going to go back and retrofit an entire application to use the ASPx textbox control, especially since this worked previously with 8.1 with the standard asp.net textbox control.
