title: How to manually drop down a DataGridViewComboBoxColumn?
body: <p>I have a DataGridView with one DataGridViewComboBoxColumn in my WinForms application. I need to drop down (open) this DataGridViewComboBoxColumn manually, let's say after a button is clicked.</p>
  
  <p>The reason I need this is I have set SelectionMode to FullRowSelect and I need to click 2-3 times to open the combo box. I want to click on the combobox cell and it should drop down immediately. I want to do this with CellClick event, or is there any other way?</p>
  
  <p>I am searching in Google and VS help, but I haven't found any information yet.</p>
  
  <p>Can anybody help please?</p>
