Placing a web user control inside a pagelist

Vote:

This one is driving me mad as I feel I've tried everything. However there must be something (hopefully something simple!) that I'm missing. Basically I have a pagelist that contains amongst its properties a url for an image and a url for a flash object. Depending on what is set for each item, I want to be able to produce code for either an image or a flash object at that point. I've been attempting this using a web user control within which I make visible the appropriate chunk of html depending on the values of the image and flash properties. This approach works well outside of a list, but within one I'm having difficulty accessing the appropriate property. I could ramble on, so if anyone has any ideas about how to best achieve this I'd like to hear them. My current fix is to call a function within the list that passes the properties along and returns the appropriate string, but I don't like having the html in the codebehind at all and would definitely prefer a solution that will allow our interface people to edit it.

Query your parent recursively for the IPageSource interface. Inside a pagelist, IPageSource.CurrentPage returns the page you're currently iterating. On a page, it will return the page itself (PageBase.CurrentPage). This is how the Property control knows how to render a property from a page in a list, or the page, depending where you put the property control in your markup. /Steve

And here is some code from a user control that sometimes is showed on a template control and sometimes on a ordinary page.


/// 
/// If there is a control implementing the IPageSource
/// interface higher up in the control hiearchy 
/// the actualPage will be set to the current page of that control.
/// If no such control is found the actualPage will be set to
/// the CurrentPage of this control.
/// 
/// If a control is found this would imply that a templated control 
/// is using this user control (for example a page list). Then we 
/// are interested of the page currently being iterated in the 
/// templated control, not the page containing
/// the templated control.
/// 
/// 
private void SetActualPage(Control control)
{			
	if ((control.GetType().GetInterface("IPageSource") != null))
	       _actualPage = ((IPageSource) control).CurrentPage;
	else if (control.Parent == null)
		_actualPage = CurrentPage;				
	else
	     SetActualPage(control.Parent);
}


private void Page_Init(object sender, System.EventArgs e)
		{
			SetActualPage(this.Parent);			
		}

It always makes me happy when I see people use the IPageSource interface. This means that they have understood how a lot of things works, both in ASP.NET and in EPiServer. The future is bright, keep up the good work, and have a great weekend :-) /Steve
