Thanks you.

You're welcome. The need to optimize rises from a bad design.My articles[^]

Ya sir Please Give Me Some code

I would highly suggest changing your design. You can NOT hide individual cells in a DataGridView. Changing the colors of the cell so the foreground matches the background also will not work because the user can just select the contents of the cell to invert the color of the background. The only way I can think of doing this would be to override the drawing of the DataGridViewColumn this data is in and paint it only if your conditions are met. But, this is quite a bit work to pull off and way beyond the scope of a forum post. I suggest Google for something like "Ownerdraw DataGridViewColumn" for examples.

You almost certainly cannot, as Crystal almost certainly doesn't tell you how long it wil ltake and provide progress indicators. You can do a progress bar that just spins tho, just load your report in another thread so your UI thread stays responsive. Christian Graus Driven to the arms of OSX by Vista.

Not sure what you are asking, but if you are having problems with 3rd party control, your best option would be to refer the problem to the author/publisher of the control.
