Hi,

We are using Nebula grid for a UI having a model based on columns rather
than rows. This is working fine, but the problem is, when we have many
columns (more than 100), the grid navigation becomes too slow. Its takes a
lot of time to even click on a cell and get focus.

Any idea how to solve this?

Thanks,

Not really. You have to profile the code to find out where the time is
spend and why a big number of columns harms the navigation whereas rows
don't.

Thanks Tom,

The problem was due to improper layout properties we were using. The problem
was not with the Grid but with the Form Layout that we were using. We
adjusted some properties of this layout and its working fine now.
