Discussion:
Need help with a Templated ASP.NET Control

Guys,

I'm at my wits end here on this templated control. I cannot get it to
function properly.
Perhaps a look by someone else can tell me where I'm going wrong.

The problem is that when I try to use the <%# Container.xxxx %> syntax for
the template in the asp.net markup, the Container field returns my parent
object and not the template object.

Any suggestions?

Thanks,
Mike

Here's the basics of the control:


[DefaultProperty("UploadURL")]
[PersistChildren(true)]
[ToolboxData("<{0}:ScannerControl runat=server></{0}:ScannerControl>")]
public class ScannerControl : Control, INamingContainer {

public ScannerControl(): base() { }

...

private ITemplate _toolbarTemplate;
/// <summary>
/// Gets or sets the template...
/// </summary>
[PersistenceMode(PersistenceMode.InnerProperty)]
[TemplateContainer(typeof(ToolbarTemplate))]
public ITemplate ToolbarTemplate {
get { return _toolbarTemplate; }
set { _toolbarTemplate = value; }
}

protected override void CreateChildControls() {
Controls.Clear();
if (ToolbarTemplate != null) {
ToolbarTemplate tt = new ToolbarTemplate();
ToolbarTemplate.InstantiateIn(tt);
Controls.Add(tt);
}
}

}


/// <summary>
///
/// </summary>
public class ToolbarTemplate: Control, INamingContainer {

public ToolbarTemplate() { }

public ToolbarTemplate(string javascriptCommand, string tooltip) {
this.JavascriptCommand = javascriptCommand;
this.ToolTip = tooltip;
}

private string _javascriptCommand;
/// <summary>
/// Gets or sets ...
/// </summary>
public string JavascriptCommand {
get { return _javascriptCommand; }
set { _javascriptCommand = value; }
}

private string _toolTip;
/// <summary>
/// Gets or sets ...
/// </summary>
public string ToolTip {
get { return _toolTip; }
set { _toolTip = value; }
}


}
