I have an Infragistics.UltraGrid and I want to add a right-click event on it. I have 6 columns in grid and when I click on last four columns of six I call context menu, but when I right click on first and second column nothing is happen.
By the way if I right click on first or second column and then right-click on other columns, my context menu disappear.
So can you please answer me what's wrong with first two columns?
