Hi,
I want to catch the event when the slider is scrolled, not when the cell is left.
Thanks.

There is a virtual method OnInplaceControlWindowProc() in the CExtGridCell class. It is spying on the window procedure of the in-place editor (which is a slider for CExtGridCellSlider) and returns true if the Windows message has been handled by the cell object. So you can override this method to handle any message from the in-place slider control.

Thanks, will try this.

Another question regarding slider cell:

I see that when not active cell, the cell displays a number. Is it possible to display a slider?
I have something like a TV tunes - contrast, brightness etc. and numbers are really meaningless.

We just added a new class CExtGridCellInplaceSlider, which implements both a slider and a scroll bar in a grid cell. Please download the updated version of the ProfUIS_Controls sample. Please note the CExtGridCellInplaceSlider class is a windowless control (does not consume HWND handles at all), which means you can safely instantiate any number of CExtGridCellInplaceSlider grid cells at any given time.

Looks great!

Thanks,
One question - will i be able to get an event/callback/derive my own class and get to know each change in the slider (not only when the cell is left.)

You can override the CExtGridCellInplaceSlider::ScrollPosSet() virtual method which is called to change the scroll position.

Can I download the CExtGridCellInplaceSlider from the ftp site?

Yes, CExtGridCellInplaceSlider is already there.

Thanks,
Works great!
