this post was super helpful. It kept me from spending too much time on the wrong path. Important to remember that when the appearance of the control changes, you have to do something different in how you access it in the controls collection for a cell.

Thanks for your quick reply!
I am using “AutoGenerateColumns=True”. The tricky part is how to do the Update since the database table design is vertical… Which now made me realize the impossible task to do a normal Update in GridView. Hmm, maybe a stored procedure will do the job, constructing the update command on-the-fly. I’ll try that! Thanks for your time.

Henrico –

You’re sort of right. It is not dynamic in the respect that the columns are hard-coded, yes, but it is dynamic in the respect that it’s not hard-bound to a datasource. If you need a TRULY dynamic GV, you can either turn on “autogeneratecolumns=true” or you can add columns at run-time. Something like “Gridview1.Columns.Add([your DataControlField object])” for each column in whatever datatable you have (do a “DataTable.Columns.Count” and then add as many rows as there are columns in your underlying datatable).

Anyways, hope this helps, and thanks for your comment!

I don’t find this example so dynamic…
You are creating a GridView with three, hard coded, bound columns. Or, am I missing something?

In my code I need to populate the GridView by autogenerating the columns. The update should then handle the situation whether there are 2 or 100 columns. Is this possible?
