I have a gridview which I populate with mostly integer data. When the use clicks the edit link I replace the label with dropdowns which are populated from a datatable. I will have up to 27 rows of data for this gridview with no more than 15 columns of data. Of the 15 columns all will be dropdown boxes except for two. Any idea how to get around this issue?

This is an ASP.Net error and should be posted in that forum.

N-E-Way...

There is a possibility you may have too much data. This is unlikely, but possible if you have a significant number of values in the drop downs.

When you go to edit mode, is only a single row in edit mode? Or the whole grid?
Are you doing any javascript manipulation of the values?
Was this a one time error?
