title: how to display custom text in data bound GridViewComboBoxColumn
body: <p>I am working on RadGridView of telerik. I have a "GridViewComboBoxColumn" with a list of strings as data source.</p>
  
  <p>Now the problem is that when I populate the grid view with data, it is possible that the value in data is not available in the strings data source for that column which results in blank value.</p>
  
  <p>I tried setting DropDownStyle to RadDropDownStyle.DropDown but that doesn't change anything. And I just need to display the data even if that is not present in the drop down list.</p>
  
  <p>Here is some code to help you understand it better.</p>
  
  <pre><code>    Dim lstValues As New List(Of String)
      lstValues.Add("Approved")
      lstValues.Add("Declined")
      lstValues.Add("Pending")
  
      Dim col5 As GridViewComboBoxColumn = RadGridView1.Columns("column2")
      col5.DataSource = lstValues
      col5.DropDownStyle = Telerik.WinControls.RadDropDownStyle.DropDown
  </code></pre>
  
  <p>Now the row being added would be following.</p>
  
  <pre><code>    RadGridView1.Rows.Add("Application Name", "Processing")
  </code></pre>
  
  <p>As you can see that column2 has no item named "Processing" so it is not displayed and showing as blank.</p>
  
  <p>Thanks in advance for the help.</p>
  
  <p>Regards</p>
