Any issues with using LoadControl() in the web service?
[WebMethod]
public string GetMyUserControlHtml()
{
UserControl temp = new UserControl();
MyUserControl ctrl =
(MyUserControl)temp.LoadControl("~/MyUserControl.ascx");
ctrl.MyProperty = "x";
string retval;
using ( StringWriter sw = new StringWriter() )
{
HtmlTextWriter hw = new HtmlTextWriter(sw);
ctrl.RenderControl(sw);
retval = sw.ToString();
}
return retval;
}
I'm also getting an empty result when trying to do it the way you have.
Seems to work Ok for WebControl (such as Label), but not UserControl.
[WebMethod]
public string Get()
{
Label l = new Label();
l.Text = "Hello world";
string retval;
using (StringWriter sw....)
{
HtmlTextWriter hw ...;
l.RenderControl(hw);
retval = sw.ToString();
}
return retval;
}

Yup, that is basically what I am doing, but I dont get any content.
StringBuilder sb = new StringBuilder();
using ( StringWriter sw = new StringWriter( sb))
using ( HtmlTextWriter htw = new HtmlTextWriter( sw))
{
MyUserControl ctrl = new MyUserControl();
ctrl.MyProperty = value;
ctrl.RenderControl( htw);
}
return sb.ToString();
When I place the user control on a page it is rendering correctly.
I must be missing something obvious ...

Subject: [ADVANCED-DOTNET] UserControl & RenderControl method
Hi,
How can I extract the html of an usercontrol?
The method renderControl is returning an empty content! :S
I want to use an usercontrol's content to be returned in a webservice.
I googled around but cannot find a solution...
