Hello unodgs
It is difficult for me to find the root cause. I have got the exception in three places, always trying to access hitems[] elems over its scope and always when moving the mouse over the Grid time after the Grid is filled with data.
I suppose this is circumstantial, but I usually use grids with few rows but hundreds of columns.
I have began to enclose the code with problems with if (hitems.GetCount() > hcol) {
...
}
Best regards
Koldo

This is workaround. The problem is hcol should never point to not existing column. I guess the problem is in GetMouseCol. Could you pleas post workable test case similar to your real app?

Hello unodgs
I will try it. Now is not a good time as I am using the program with other people so I do not want it to crash.
But of course the way to solve the problem is to begin with preparing a test case.
