Question

For example I got a <asp:FormView> and there are IDs inside. Why is that I can’t get one of the ID inside the <asp:FormView>, the error shows as “The name ‘commentsLabel’ does not exist in the current context“

How to get the ID of one of the <asp:TextBox> that is inside <asp:FormView> ?
Thank you.

The question isn’t very clear, but I suppose this is what you have:

<asp:FormView runat="server" ID="aFormView">
  <ItemTemplate>
    <asp:Label runat="server" ID="commentsLabel"/>
  </ItemTemplate>
</asp:FormView>

and you want to access commentsLabel in the code behind of the control/page on which you have this markup.

Since FormView is a naming container, you can find the controls inside it like this:

Label commentsLabel = (Label)aFormView.FindControl("commentsLabel");
