When we put the last version of Infragistics controls, some of the grids now don't have selected rows. I click on the grid's row and nothing happens.

Can somebody tell me what it could be the problem.

In DisplayLayout I set the property SelectTypeRowDefault="Extended" 

We have more than 10 places in the project where we use UltraWebGrids, and for some reason in 4 places, we don't have selected row functionality. Some of the grids are multi band, some are autogenerate columns, and in one page works but in another don't.
