is not allowed here because it does not extend class 'System.Web.UI.UserControl'

Question

I have created a User Control that extends the DEVExpress ASPxGridView. My goal is to have this control be a template (style settings, shared properties) for all the times I would but the GridView somewhere, but instead of having to add the properties and Styles, I could use it as a template. All other properties, events, etc would be inherited from the base class

Here is my ascx.cs code

namespace CORE.Web.UserControls
{
   public partial class ucGridView : DevExpress.Web.ASPxGridView.ASPxGridView
      {
      }
}

and the ascx code

<dx:ASPxGridView ID="gcGridView" runat="server" AutoGenerateColumns="False" Styles-AlternatingRow-Enabled="True">
<Settings HorizontalScrollBarMode="auto" VerticalScrollBarMode="auto" VerticalScrollableHeight="500" />
<SettingsPager PageSize="20">
    <PageSizeItemSettings Visible="true" ShowAllItem="true" />
</SettingsPager>
<SettingsBehavior AllowFocusedRow="true" />
<Styles>
    <Header VerticalAlign="Top" Wrap="True"></Header>
    <AlternatingRow Enabled="True"></AlternatingRow>
</Styles>

and where it is put in the aspx page

<uc1:ucGridView runat="server" ID="ucGridView" DataSourceID="masterStatsObjectDataSource" />

There are other issues, like columns and whatever that know I will deal with, but I am hitting a roadblock just getting it to work at runtime

I get this error message

'CORE.Web.UserControls.ucGridView' is not allowed here because it does not extend class 'System.Web.UI.UserControl'.

Line 1 of the aspx page is

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="ucGridView.ascx.cs" Inherits="CORE.Web.UserControls.ucGridView" %>

I am not sure where to go from here, as this should be easy. Any help would be greatly appreciated.

Thanks

Solution

This Control might not be in the current namespace.

Can you explain this a little more? I have the same issue and am not sure what to do. Can you give an example of the correct code so I can see how it differs from the original code in your post?

That helped in my case. Strangely, the error did only occur when I tried to "publish precompiled." After fixing the namespace issue (it was wrong in the website registration, not in the C# part), everything compiled succsssfully.
