Subclassing MSHFlexGrid control to show alternate colors

[sanjivani]

Hi,

Have anyone tried subclassing MSHFlexGrid control. I want to subclass it to show alternate backcolor in rows. I can do it by looping through rows but it is creating problem when there are large number of rows.

I also want to show row number in first column of the grid by deafult when row gets actually added/ created.

What sort of problem do you encounter when having large number of rows?

What kind of problems? I'm doing that with 15000 rows. You just have to paint 1 time when its populated, after that, just the last selected row must be repainted.

It is too slow for large number of rows. It is visible to user when alternate coloring of grid goes on.

Could you post the code you are using?

Set the Redraw property to False before the "alternate coloring" code is executed. Set it back to True when done. You should see a significant performance gain.
