Hi All,
I am having a problem:
I clicked a button, in the start of code, I wrote a line to visible the HTMLPlaceHolder content, that is some html stuff. when code ends, I am setting is visibility to off. As execution of code will take approx 45 seconds, it should show the HTML content of controls. but its not showing the HTMLPlaceHolder in whole process.how can I implement it?
The hTML Content from HTMLPlaceHolder is howing properly if I set its visibility on in the start of code, and not set visible on -off as I menation earlier.

We are not aware of any problems of the functionality you mention. I tested your scenario and I could not reproduce the issue you reported. If you can provide a sample project that demonstrates the issue I will be able to investigate it.

If you want to send us an attachment you need to open a support ticket. Attachments are disabled for forum posts.
I tested the code you have pasted and the reason why you do not see anything is because of the for loops.
Silverlight's UI is single-threaded and the nested for loops of your application block the thread. That is why you cannot see the PWGrading (RadHtmlPlaceholder) changing its HtmlSource property.
You can overcome this by creating a new thread, but this will significantly complicate your solution.
If you can provide more information on what you are trying to achieve maybe I'd be able to help, but for the moment I'd suggest you do not use the nested for loops.
