Hi,
We received your sample application - did you send two of them ?
Anyway, I took a quick look and the problems you have are easy to fix. First, you seem to have two references to Gizmox.WebGUI.Client. Remove both of them,and then reference Gizmox.WebGUI.Client again to make sure you have the correct up to date one.
Second, the code you have looks like a code generated by a designer in version 6.4.x that you are now trying to use in 6.3.x. Is that a correct assumption. If I open your application in version 6.4 and rereference the Gizmox.WebGUI.Client there are no errors.
So, what you simply do, after you fix the above, is that you locate these three lines containing non-existing properties, and just delete or comment out the lines.
That should fix these problems.
Hope it helps,
Palli
