I have an application that is using the new DataGridView in Visual Studio 2005. Its kind of a complicated grid in that the columns are mixtures of different types of cells (combo box, text box, and check box cells). This application is sort-of mimicking an excel spreadsheet.

Anyway, the roadblock that I am up against now is that when I set a cell value in my grid, it is VERY slow. I have only about 120 rows and 5 columns in my grid.

When I step through the code to figure out what is so slow, everything executes fine except when I execute this line:

Grid(ColumnIdx, RowIdx).Value = strParms

When I execute this in the debugger, I can make out text in the status bar of the IDE that flashes up really fast and continually and says "Loading Symbols for XXXX" and XXXX continually changes to nonsense names.

I'm up against a deadline with this project. I thought the datagridview would work well enough that I didn't need to buy a 3rd party control, but now I'm worried that I made the wrong decision...

Any help would be SO appreciated!
