  Hi!
  
  Is there a way to select a row with the right mouse button in C1TrueDBGrid?

  Hello,

  Please use the following lines of code:

  
   private void C1TrueDBGrid1_MouseClick(object sender, MouseEventArgs e)
          {
              if(e.Button == MouseButtons.Right)
              {
                  if(c1TrueDBGrid1.SelectedRows.IndexOf(c1TrueDBGrid1.RowContaining(e.Y))>=0)
                      c1TrueDBGrid1.SelectedRows.RemoveAt(c1TrueDBGrid1.SelectedRows.IndexOf(c1TrueDBGrid1.RowContaining(e.Y)));
                  else
                  c1TrueDBGrid1.SelectedRows.Add(c1TrueDBGrid1.RowContaining(e.Y));
                  
              }
          }
  
  

  Thanks,
  
  Mohit

  If C1TrueDBGrid1 contains ContextMenuStrip, the C1TrueDBGrid1_MouseClick event will not be fired when right mouse button is clicked.
  
  Is there any way to solve this?

  Hello,

  The MouseClick event fires when you press and release the Mouse button but as the ContextMenu appears on MouseDown so it is preventing the execution of the MouseClick event.

  As a workaround you can use the same code in the MouseDown event:

    private void C1TrueDBGrid1_MouseDown(object sender, MouseEventArgs e)
         {
             if (e.Button == MouseButtons.Right)
             {
                 if (c1TrueDBGrid1.SelectedRows.IndexOf(c1TrueDBGrid1.RowContaining(e.Y)) >= 0)
                     c1TrueDBGrid1.SelectedRows.RemoveAt(c1TrueDBGrid1.SelectedRows.IndexOf(c1TrueDBGrid1.RowContaining(e.Y)));
                 else
                     c1TrueDBGrid1.SelectedRows.Add(c1TrueDBGrid1.RowContaining(e.Y));
  
             }
         }

  Thank you.
  
  I already solved it by manually showing ContextMenu on right mouse click, instead of assigning ContextMenu to the c1TrueDBGrid1.
