WPF Datagrid COMException on using IncludeHeader ClipboardCopyMode
Found this from Andrew Smith at http://blogs.infragistics.com/forums/t/35379.aspx -
Technically only 1 process can open the clipboard so if another process has it opened the subsequent requests will fail until the first releases the clipboard. This was sort of handled in the WinForms Clipboard class where it would retry the set with a delay in between each try but the WPF clipboard class doesn't do this so if it fails on the first show the exception occurs. Even then we should probably catch the exception and raise the clipboard operation error if it still fails.
Same thing is explained and some ways to fix it are mentioned on this italian blog -
Following MSDN forum thread suggests that this could be machine specific problem, can you reproduce this on other machines? -
