Are you hiding columns using grid.Cols.Hidden[colIndex]? If, try setting the ColWidths to zero instead to see if that avoids this problem.
grid.Model.ColWidths[colIndex] = 0;

Is this a known issue?

If the grid is parentted to a container control (like a panel or usercontrol) and the container is not finally sized when the grid is added to the containers control collection, and the grid is not docked.Fill, then the grid''s client area can be clipped by the container and you would see behavior like you described. Are you using a container to hold the grid. Is the grid docked or anchored in a manner that the container is clipping the grid''s client area? This is the only issue of this type that we are aware of in3.2.1.0.

That''s exactly how this GDBD is used. The workaround you suggested seem to work fine but I had all logic implemented with HideCols where some columns need to be restored and if the width is set to zero I loose the original width.
I would really appreciate if you guys can provide a fix for this issue in next release.
Thanks, Jose.

Is your GDBG docked fill, and was it the last control that you added to the container? If you dock it some other way, or it was not the last control added to the contatiner, there is no way to prevent this behavior as you woul dhave to explicitly size teh grid properly in your code when the container''s size chnages in these cases.

my GDBG is docked fill and it is contained in a user control (ucA). That user control is also contained in another user control (ucB). I removed, reinserted and docked again ucA in ucB just to make sure it was the last control added but I''m still getting the scrolling issue.

Hi, Jose
I have simliar problem as you. Instead of Set Column widths to zero, I catch HScorll Bar event, everytime scroll chnaged, I refresh Grid.
It works fine. I test 400 rows with 25 coluumns. The preformance is not that bad.
By The way, I do think this is bug. Hopefully, they can fix in the next release.
Thanks.

What versions are you using? Is it 3.2.1.0?
I tried to reproduce this problem in this sample using 3.2.1.0. Can you tell us how to see the problem in this sample so we can get this fixed? Or, can you attach a sample project showing this problem?

It seems to be the same problem. I have same situation where columns are hide/show based on user''s data input.
Settin Width to zero is not a solution in my case, for the reasons I explained in previous post.

Hide the columns after the grid is displayed. Add buttton to Hide/Show column in Form1 and you will be able to replicate this issue.
