I am getting the below cross thread operation coming from the synfusion dll while I am applying filters.
The issue comes randomly. While I apply filters. In my inside code I haven't added any code for filters as it is automatically working using syncfusion. Require your urgent help in this. The application is used for adding a powerpoint pluging
