Load template from embedded resource

Question

How can I load an embedded resource as an ITemplate? The LoadTemplate() method only takes a string virtual path, and obviously this will not work for embedded resources.

Answer 1

Your control should look like it:

public class Con : Control
{
    public Template Content { get; set; }

    protected override void CreateChildControls()
    {
        base.CreateChildControls();

        Content = new Template();

        // load controls from file and add to this control
        Content.InstantiateIn(this);
    }

    public class Template : ITemplate
    {
        public void InstantiateIn(Control container)
        {
            // load controls
            container.Controls.Add((HttpContext.Current.Handler as Page).LoadControl("Emb.ascx"));
        }
    }
}

Then the embedded file:

<%@ Control Language="C#" %>

Then when using the control it will load the embedded resource, so using:

<%@ Register Assembly="TestWeb" Namespace="TestWeb" TagPrefix="c" %>

Will create a TextBox.
