Hiding GridView Columns without Re-Firing ObjectDataSource Select

[Guest]

Based on wether a row is selected in a GridView I need to HIDE the last two
columns of a gridview. I do NOT need to make the cells invisible I want to
hide the entire column.

When I set the Visible property on the columns it causes the underlying
ObjectDataSource to re-issue the Select statement.

How can I hide these columns without double clutching the ODS Select?

Loop through the Rows collection and hide the cell for the column in every
row individually. Don't forget the header.

Hi jpondy,

From your description, you want to hide some certain columns in GridView
when a certain Row is selected, correct?

As for the columns, do you mean only the columns belongs to that selected
row or those columns for all the row? Yes, I agree that hiding the column
through Column.Visible is not a good approach. If you just want to hide
those columns for the selected row, you can use RowCreated event and if the
row is the selected one(make the certain columns cell invisible(set the css
style "display" to "none"). If you want the entire column to be
invisible, you can set each column cell(of each row) of that certain column
to invisible(through CSS style). How do you think?
