title: Get "data grid" data to text boxes using column name
body: <p>I'm using this code to get my data to text boxes. </p>
  
  <pre><code>TextBoxName.Text = gridViewName.SelectedRows[0].Cells[0].Value.ToString();
  </code></pre>
  
  <p>But, all the time this column index may not be the same one. </p>
  
  <p>So, I need to get this datagrid value to the text box using its column name.</p>
  
  <p>Is it possible? </p>
  
  <p>If possible, what will be the code?  </p>
