在datagridview C＃中禁用列标题

Question

I have a datagridview 'audit_TrailDataGridView'. I need to disable the column headers of this ie: nothing should happen when user clicks on the column headers.

private void audit_TrailDataGridView_ColumnHeaderMouseClick(object sender, DataGridViewCellMouseEventArgs e)
         {
            //do what?

         }

Please help.

Answer 1

It could be that something undesirable happens because when a user clicks on a header an event is raised intended to handle the situation when a user clicks on an actual cell, not a header (for example, the CellDoubleClick event). You need to manually check inside all such events that the cell clicked is not a header:

 private void dataGridView1_CellDoubleClick(object sender, DataGridViewCellEventArgs e)
 {
     if (e.RowIndex >= 0)
     {
         //do something here
     }
 }

Answer 2

I had a similar problem with dataGridView1_SelectionChanged event.

I wanted the DataGridView to be sorted when the header columns clicked, but not implement the code that I wanted to be runned for non-header row clicks.

So basically I found a stupid solution, I added a huge try catch block inside dataGridView1_SelectionChanged method containig everything in this method.

Maybe this will work for you or someone else too.
