Currently I'm generating UserControls as follows in an abstract base class so they are available for any other pages that implement the base class:
// doc is an XML file that may or may not contain a TopStrapline node
var pageControls = new {
TopStrapline = (from strap in doc.Elements("TopStrapline")
select new TopStrapline
{
StraplineText =
开发者_StackOverflow社区(string)strap.Attribute("text")
}).FirstOrDefault(),
// loads of other UserControls generated from other nodes
};
// if there's a StrapLine node, I want to make it available as a property
// in this base class. Any page that needs a TopStrapline can just add the base
// class's TopStrapline to a placeholder on the page.
if (pageControls.TopStrapline != null)
{
this.TopStrapline = GetTopStrapline(pageControls.TopStrapline);
}
private TopStrapline GetTopStrapline(TopStrapline strapline)
{
TopStrapline topStrapline = (TopStrapline)LoadControl("~/Path/TopStrapline.ascx");
topStrapline.StraplineText = strapline.StraplineText;
return topStrapline;
}
What's bugging me about this code is that I can create an instance of TopStrapline
with the LinqToXML but it's no good as a user control because I need to load the UserControl with LoadControl
. This works but it seems a bit clunky. Ideally I could execute LoadControl
directly into the pageControls
anonymous object, and then assign that loaded control into the page's property.
Is this possible? Can anyone suggest a better solution to this issue? Thanks
Would this work for you?
this.TopStrapline = doc.Elements("TopStrapline")
.Select(e => {
var control = (TopStrapline)LoadControl("~/Path/TropStrapLine.ascx");
control.StraplineText = e.Attribute("text");
return control;
}).FirstOrDefault();
