SYMPTOMS

When you put a DataGrid Web server control in a MultiPage Microsoft Internet Explorer Web Controls control through code, the DataGrid does not appear in the Web Form in Design view. The DataGrid also does not appear when you view the Web Form in the browser.

CAUSE

This problem occurs because the DataGrid is not bound to any data.

Typically, when a DataGrid control is at the top level of the code, the Designer object instantiates. This behavior creates a dummy data source for the DataGrid, and then the DataGrid appears as expected.

However, when the DataGrid control is located in another control (the MultiPage control in this example), the DataGrid control does not go through the design-time code path that it would have gone through typically. Therefore, the DataGrid does not appear in the browser because the DataGrid has not been bound to any data. In this scenario, the DataGrid also does not appear in Design view at design time.

STATUS

This behavior is by design.

 POSITION: absolute; TOP: 42px" runat="server" Width="520px" Height="320px"
 BorderStyle="None"> <iewc:PageView id="FirstPage"> </iewc:PageView> 
</iewc:MultiPage>
  11. Switch to the Design view of WebForm1.
  12. Click the MultiPage control.
  13. In the toolbox, double-click the DataGrid control.
  14. Switch to the HTML view of WebForm1
  15. In HTML view, put the existing code that creates the DataGrid between the following tags:

    <iewc:PageView>

    </iewc:PageView>

  16. Switch to the Design view of WebForm1.
