PortalModuleControl Error...7/16/2004 5:11:07 AM

0/0

Hi Guys,

i create a control (.ascx) file which contain a XSL transforms control, which open a HttpWebRequest to a URL then get the XML. After load the XML string to the XML document then i assign a XSLT as the transformSource for the XMLDocument object.


i insert all the backend stuff... but the dt.aspx execute to this line, i got type mismatch error...
--> PortalModuleControl portalModule = (PortalModuleControl) Page.LoadControl(moduleSettings.DesktopSrc);


so i try to test out the code... by just adding the control by control instead of using the PortModuelControl and it works fine....
--> Panel.Controls.Add(Page.LoadControl("~/controls/myXMLContorl.ascx"));

any idea why is not working?

Thanks a lot guys!!!

Pat, I have created an application which retrieves xml data from a weather website.

First, Remember that PortalModuleControl inherits UserControl -- which is why we don't let our custom userControls Inherit from the actual UserControl class, but instead we use PortalModuleControl (PMC) ( A great way for multiple inheritance when you think about it.)

Now, in my Class file called WeatherCtl, I have:

Public Class Weatherctl Inherits PortalModuleControl. Because I Inherit from PortalModuleControl, My Control is a UserControl and it is a PortalModuleControl. Remember your is a... and has a... inheritance versus composition relationships.

My Class is also a WeatherCtl. I have no need to cast this class to a PortalModuleControl because it is one. In the page attributes, I have @Page...Inherits="rw.lib.Weatherctl"
Keeping in mind that my class Weatherctl inherits PortalModuleControl which in turn inherits UserControl.

Now, I am not really clear on exactly what you want to cast to a PMC or why you would want to, but I don't see how you could cast an existing UserControl which does not inherit from PMC to a PMC. Your code snippet was so brief, I can't say I am too helpful.

Best of Luck,

Rick...

I have been receiving the same error.

I have created a Control that is as simple as it gets:

<%@ Control Language="c#" AutoEventWireup="false" Codebehind="Sample.ascx.cs" Inherits="ASPNET.StarterKit.Portal.DesktopModules.Sample" TargetSchema="http://schemas.microsoft.com/intellisense/ie3-2nav3-0"%>
<p>I am hoping that this will work....</p>

I am getting the same error message that Pat has been getting.

Any ideas?
