I have attached the code for Selection of a single row (currently activated). But when the form is open at a large resoultion like 800 * 600, the scrollbar of form appears. And when selecting the row results black lines of the selected row. and also not refreshing the range of selection. Is this control''s problem? I have chosen "64, 10, 36, 106" as the Alphablend color of the grid. Is this color''s problem or VB.NET form''s scroll problem?
I did not see any attachment so I could not see how you have things working.
Do you have the grid.AllowSelections property set so it also includes the AlphaBlend flag? If not, this tells the grid to use just invert the selected area on the screen instead of using the hosen alphablendselectioncolor. And this may make the selections look bad.
