title: WinForm : How to load rad autocomplete textbox from database with text and value in a block
body: <p>I have a code like this:</p>
  
  <pre><code>public void LoadDiseaes()
  {
      da.OpenConnection();
      Disease disease = new Disease(da);
      txtDisease.AutoCompleteDataSource = disease.GetAll();
      txtDisease.AutoCompleteDisplayMember ="DiseaseName";
      txtDisease.AutoCompleteValueMember ="ID";
  }
  </code></pre>
  
  <p>Initially, I have used above code to bind autocomplete <code>textbox(txtDisease)</code> with its <code>Datasource</code>.  </p>
  
  <p>``````````````````````````````````````````````````````````````````````````````````````</p>
  
  <p>Then, after I selected particular disease and saved the record. This work fine.  </p>
  
  <p>My question is that when I want update that record I want to populate my <code>AutoComplete(txtDisease)</code> with the <code>Disease</code> from the Database with its Text and Value in a block which I have selected during saving the record but it gives me only a text and not value in background.</p>
