Hey,

since you've posted this to the WebDataGrid forum, but you are referring to UltraWebGrid in the title, could you clarify which one you're using - WebDataGrid, or UltraWebGrid?

The reason to have them hidden by default is primarily for performance - in this way, only one instance of the combo/dropdown are used for the whole grid, and their position and data source are just changed depending on which cell you click on. Otherwise, if you have X number of records, there would be X number of dropdowns for every column, that's basically X control instances, separate from the grid, which may be a performance overkill - depending on how many records you load in the grid, of course.

Thanks very much,

Angel
