title: Get display value from combobox in radgridview
body: <p>I am using Telerik's RadGridView to display some data.  One of the columns in this gridview is a combobox, which is populated like so:</p>
  
  <pre><code>DataTable dtContractorName = A133DB.GetContractorsForCombo(true);
  GridViewComboBoxColumn contractorNameColumn = new GridViewComboBoxColumn();
  contractorNameColumn.UniqueName = "ContractorID";
  contractorNameColumn.HeaderText = "Contractor";
  contractorNameColumn.DataSource = dtContractorName;
  contractorNameColumn.ValueMember = "ContractorID";
  contractorNameColumn.DisplayMember = "ContractorName";
  contractorNameColumn.FieldName = "ContractorID";
  radGvReviews.Columns.Add(contractorNameColumn);
  </code></pre>
  
  <p>This works just fine for displaying the data properly in the gridview, but I would like to also show the displaymember of the current row on a separate part of my form when the cell is double-clicked. </p>
  
  <p>Example:</p>
  
  <pre><code>private void radGvReviews_CellDoubleClick(object sender, GridViewCellEventArgs e)
  {
      MessageBox.Show(e.Row.Cells["ContractorID"].Value.ToString());
  }
  </code></pre>
  
  <p>Unfortunately, this will only display the ValueMember for the column (i.e. 1, instead of Fred; 2, instead of Bob), and the control does not contain a definition for the "DisplayMember" or "Text" properties (where I would expect to find the value that is actually being displayed on screen).</p>
  
  <p>Any ideas on this one?</p>
