A (less) simple include for ASP.NET

@Brett: yep. Still not getting IntelliSense on those properties. Working on an interesting solution, going almost full-circle to where we started...

Just replace this as the UserControl in my comments above...

System.Web.UI.Control control=LoadControl(Path);

foreach (string key in this.Attributes.Keys)

{

PropertyInfo pinfo = control.GetType().GetProperty(key);

pinfo.SetValue(control, Convert.ChangeType(this.Attributes[key], pinfo.PropertyType), null);

}

this.Controls.Add(control);

then you can add properties like

<x:Control runat=server Path="~/TheControl.ascx" idx="1" category="books" />

Good for standard types.

I don't know: if you use this much it looks like an awful lot of extra reflection code to go through at runtime. Could be a real performance hog for not a lot of syntax savings. I'd like to see some load testing.

@Brett: yes, I'm preparing the next post along those lines, except you'll also be able to set properties for the included control. :) And maybe something else after that...

I have done this for a while now as i deal with a graphic designer who doesn't want me futzing too much with the aspx files...

1. Add a UserControl that just has this:

public string Path { get; set; }

protected void Page_Load(object sender, EventArgs e)

{

this.Controls.Add(LoadControl(Path));

}

2. In web.config

<pages>

</controls>

</pages>

3. On any aspx page - regardless of the existence of the @Page directive or control registration etc....all you do is add the glabally registered control and enter the path of the control ... <x:Control runat=server Path="~/TheControl.ascx" /> - postback etc. works as normal

4. ???

5. Profit.

This is really interesting. I don't see a need for it right now, but I'm sure it's an awesome thing to know.

Why is it that people don't prefer to Register their ascx file but persistently use include instead?

Cool, this is looking a lot like Rails' partial views. It would have a lot less Reflection cruft if you used C# 4.0 dynamics ... or if you wrote it in VB. ;)
