SqlDataReader & user control

Question

i try to use userControl to display SqlDataReader data.

in the main page

  public SqlDataReader Data2;

...

 <uc1:WebUserControl ID="WebUserControl1" RData1="<%=Data2 %>" runat="server" />

and in the userControl

  Repeater1.DataSource = RData1;

        Repeater1.DataBind();



     <asp:Repeater ID="Repeater1" runat="server">    <ItemTemplate> 
 <div class="row">   <b> 
 <%#DataBinder.Eval(Container.DataItem,
 "replay_subject")%></b><br />   
 <%#DataBinder.Eval(Container.DataItem,
 "replay_text")%><hr/> </div>   
 </ItemTemplate>
      </asp:Repeater>

But i keep getting this error

Cannot create an object of type 'System.Data.SqlClient.SqlDataReader' from its string representation '<%=Data2 %>' for the 'RData1' property.

Answer 1

You can't assign RData1 using that inline code on the ASPX. The compiler try to convert Data2 to a string representation in order to set the property and RData1 is expecting a SqlDataReader so it fails.

You have to assign it on the code behind like this

WebUserControl1.RData1 = Data2;
