Thanks a lot .

it's another problem. I described the solution here. You need just call  triggerHandler("jqGridAfterGridComplete") directly after setFrozenColumns.

I will try to create a test case for it.

I thried to do this, but it not help. The problem is that jQuery.height returns 0 it the grid is hidden with display:none.

The most practical workaround would be to use activate callback of jQuery UI tabs, test whether the activating grid has whether frozenColumns parameter of jqGrid are set to true (grid already has frozen columns) and call setFrozenColumns if not. In the way one will call setFrozenColumns on visible grid on the first activation of the tab contains the grid.

Another more alegant solution would be changing calculation of height. One can use the trick from here (or here) where one use visibility: hidden !important; display: block !important; styles to mesure dimensions of elements which could be hidden.

It works on the simple test case with addRowData but not in my real case that uses json to load data.

I tried to move the setFrozenColumns() in the gridComplete event but it shows the same problem.

Thank you for the test cases. This help us.

Frozen Columns are not compatible with addRowData (sorry)

You can try to use data parameter in grid to add data and then call setFrozen Colummns.

In your case I think (not tested) this will work if you first add the data with fillGrid function and after this call setFrozen Columns.

If I enable frozen columns the headers of the frozen columns in the hidden tab are overwritten by the first row of data.

You can see a test case here  http://jsfiddle.net/danypd69/quuvR/2/

check the second tab (Grid2) and you will see what I mean
