Help with Page.LoadControl(Type t, Object[] parameters)

[Guest 20221009]

I have done very little Webforms dev ever since MVC beta came out and I am battling to load a user control with parameters.

I have a UseControl for handling comments need to add this via code based on certain conditions. What does this method expect as the Type. I have searched and I m yet to find a good resource on this.

Control ContentComments = Page.LoadControl(contentType, parameters);

Control ControlComments = Page.LoadControl(ControlComments, parameters);

Does this help?

Your link got me in the right direction, thanks. It throws a : Constructor on type 'Namespace.Controls.ChildContent' not found.

I have a default contructor on this and I am not sure what I am missing. Bloody Webforms!

On a simpler note, try Page.LoadControl("UserControlPageHere").

This works fine and I had looked at that option. The only drawback is that I am unable to to pass the control data if I do it this way, unless there is a way to do it.

Got it to work this way.

   ChildContent ContentComments = new ChildContent();
                        ContentComments = Page.LoadControl("~/Controls/ChildContent.ascx") as ChildContent;

                        ContentComments.contentID = contentID;
                        ContentComments.ContentBody = ContentBody;

                        ContentComments.ID = "LinkedContent" + i.ToString();                        
                        
                        PlaceHolder1.Controls.Add(ContentComments);

I am pretty chuffed, but my Webforms skills suck badly these days.

Well done. It had crossed my mind to set parameters after the fact, and there you go.

Haha! Would've suggested that if I read this thread earlier. User controls come in real handy in an AJAX / Web Service environment when you can render the output to HTML, if you extend the Page class a bit to allow for that. I somehow find myself still enjoying Web Forms (albeit my own severely butchered, quasi-MVC form) more than the "proper" MVC framework provided by Microsoft. I guess old habits die hard...
