I noticed one strange thing with radgridview, under WPF (see the screenshot below)
This is a complex production planner screen, and as far as i just click the cells with mouse it works perfectly. But when i use the arrow keys to navigate between cells two thing can happen:
1. If i push less frequently the actual cell switches without problem.
2. If i push quicker, or if i hold the button the grid leaves random selected cells behind.
There are a few things in the SelectedCellsChanged event, which runs in ~200ms. This 200ms is mostly an SQL query, i run it each time to fill some other fields based on the selected cell. As i guess: if i switch faster than this, the bug appears, if i select slower than this, then it switches the cell without any problem.
Do you have any advice how can i solve this? I tried to put .unselectall after each, but it just made it worse.
