Has anybody found a way to disable a column in DataGridView i.e prevent it
being selected. With DataGrid it was fairly easy to check on the column being

possible with DataGridView.

Hi,
I have a DataGridView control, where I am setting its Datasource
property to a datatable. The DataGridView has it's MultiSelect property
set to false
I also have a handler for the SelectionChanged event.
When I load the data, I set the DataSource property, and then call
ClearSelection() to make sure there are no selected rows.

I have a windows app with a DataGridView (lets call it DGV). At some
point in the life of my app I want to clear the selection of the
currently selected row (Multiselect=false) from DGV - to do that I
tried this:
DGV.ClearSelection()
Cosmetically this appears to work but it appears that the DGV still
stores the index...
