I'm currently not sure how to implement a solution for this problem. I want a RadGridView which has the ability to select multiple items whether it's shift or ctrl clicks, but I once the items are selected, I want the user to be able to right click and make a selection in a menu. For instance, if a grid column is just a column to designate colors of each item, the user can select in the menu, change color and a window pops open and then they can select the color. Once the color is selected, then all the items that the user selected would be changed to that color. I understand I should use the RadContextMenu, but I'm not certain on how to use it with multiple selections.
Also, how can I make a custom column? For instance, I could just have a rectangle that would fill up and items cell and be a randomized color?
