Dynamically Loading User controls

[tperri]

I'm dynamically loading user controls into a place holder, which is working fine, but the properties I've created aren't available.

Control avgRateControl = (Control)Page.LoadControl("_controls/AverageRates.ascx");
phRatesList.Controls.Add(avgRateControl);
avgRateControl.hotelList = getHotelRates;
avgRateControl.searchStructure = searchStructure;

Do I need to do something else to expose them?

Thanks in advance for the help!

What do you mean by "aren't available"? Does intellisense recognise the "hotelList" and "searchStructure" properties? If not, how have you declared these properties (i.e. are they Public) and can you give an example?

No, they don't show in intelisense. If I drag and drop the control directly on the page, the properties are accessible, no problem. But when I looad like this, they are not. Here is one of my properties decalred. They are all declared the same:

    private XmlDocument _hotelList = new XmlDocument();
    public XmlDocument hotelList
    {

        get
        {
            return _hotelList;

        }
        set
        {
            _hotelList = value;

        }

    }

Ah, I think I see why now. You've loaded the control with the type "Control" which means it is actually a System.Web.UI.Control. Since this object doesn't have "hotelList" and "searchStructure" properties the object doesn't know what the are and causes an error.

You'll probably have to cast your control to the user control type before you can access the properties you have created.

Alternatively, you could load it as the correct type to start with e.g.

        WebUserControl avgRateControl = (WebUserControl)Page.LoadControl("_controls/AverageRates.ascx");

NOTE: Replace "WebUserControl" with your user control type so in this case it's probably "AverageRates".
