title: remove default row selection datagridview
body: <p>I have a datagridview that when it loaded first row is selected. I want to delete a record but I don't want first row select. I want message to user that first select a row then click delete button. I try these code but they don't worked.</p>
  
  <pre><code>//kharidDataGridView.Rows[0].Selected = false;
  
  //kharidDataGridView.ClearSelection();
  
  //kharidDataGridView.CurrentCell = null;
  </code></pre>
  
  <p>I use below codes in WPF:</p>
  
  <pre><code>object item = datagrideview1.SelectedItem;
              if (item == null)
              {
                  //message to user
              }
  </code></pre>
  
  <p>thank you</p>
