Ok so i am using SiteFinity and playing with the RadToolTipManager. Because this is SiteFinity, my RadToolTipManager is inside a UserControl. That said i am trying to dynamically load the UserControl for the RadToolTipManager from this UserControl... Now that i have confused everyone sufficients, i am also trying to access properties within the RadToolTipManager Control i am loading Dynamically. I am frustrated cause none of the example on the Telerik site show the code behind of the user control.

I need help and i need help BAD...

So here are the details:

Results.ascx.cs

On an ItemDatabound mothd i add the control to the RadToolTipManager

    
            RadToolTipManager1.TargetControls.Add(((Label)rpti.FindControl("lblFlightNum")).ClientID, "", true);

As per the examples the code behind here has the following methods which the RadToolTipManager calles:

    
                protected void OnAjaxUpdate(object sender, ToolTipUpdateEventArgs args) 
        
                { 
        
                    this.UpdateToolTip(args.Value, args.UpdatePanel); 
        
                } 
        
                private void UpdateToolTip(string elementID, UpdatePanel panel) 
        
                { 
        
                    Control ctrl = Page.LoadControl("~/UserControls/PFV_3.0_TooltipControls/FlightInformation.ascx"); 
        
                    panel.ContentTemplateContainer.Controls.Add(ctrl); 
        
                    //ProductDetails details = (ProductDetails)ctrl;

                    //details.ProductID = elementID; 
        
                }

Notice above i have commented out the lines where the property on the loaded control is accesses as i do not know how ProductDetails is inherited down and there is no explaination of this anywhere... If it were part of the ASPX page i might be able to access it but in my case it is part of a ASCX UserControl and being loaded dynamically.

So here is my UserControl i am trying to LoadOnDemand

FlightInformation.ascx.cs

    
            using System; 
        
            using System.Data; 
        
            using System.Configuration; 
        
            using System.Collections; 
        
            using System.Web; 
        
            using System.Web.Security; 
        
            using System.Web.UI; 
        
            using System.Web.UI.WebControls; 
        
            using System.Web.UI.WebControls.WebParts; 
        
            using System.Web.UI.HtmlControls; 
        
            public partial class UserControls_TooltipControls_FlightInformation : System.Web.UI.UserControl 
        
            { 
        
                string ParameterArray; 
        
                public virtual string Parameters 
        
                { 
        
                    get 
        
                    { 
        
                        return ParameterArray; 
        
                    } 
        
                    set 
        
                    { 
        
                        ParameterArray = value; 
        
                    } 
        
                } 
        
                protected void Page_Load(object sender, EventArgs e) 
        
                { 
        
                } 
        
            }

Can someone please help me load this control Dynamically and have access to it property from the OnAjaxUpdate method!

Thanks in advance,

Duncan
