  I have a Rating control in a FormView which is populated using a SQLDataSource.

  </asp:SqlDataSource>

  
  My issue is that when I attempt to update the data, the rating is not updated and the field value is ste to null.
  
  How can I use the Rating control in the update portion of the formview?
  
  Thanks in advance.

  Hello Allan,
  
  I created a sample project, based on the code snippet that you sent and I was able to reproduce similar issue - after every update the value of the RadRating is lost. In order to solve the problem I made sure that the value of the rating is preserved by adding it to the update parameters in the Updating server-side event of SqlDataSource. The example below demonstrates this:
  

  protected void Sqldatasource1_Updating(object sender, SqlDataSourceCommandEventArgs e)

  {

      e.Command.Parameters["@UnitsInStock"].Value = ((RadRating)Formview1.FindControl("UnitsInStock")).Value;

  }

  UnitsInStock is the ID of the RadSlider used in this example.
  
  As the RadRating control usually accepts Value of type Decimal, please cast the specified value to that type:
  

  <telerik:RadRating ID="UnitsInStock" runat="server" Skin="WebBlue" ReadOnly="true" Value='<%# Convert.ToDecimal(Eval("UnitsInStock")) %>'>

  
  I have attached my test page so that you can use it as a basis for your further development.
  
  If the information listed above does not help you resolve your difficulties please provide more detailed description of your scenario, as well as steps to reproduce the encountered problem.
