I have gotten it to work but the problem I am having is passing in a variable using contextKey. I need to find a way to set the contextKey parameter based on a variable that is being passed from another page. Should be simple but....

Put some code up and I will see if I can help you out with your problem.

Hi Tim,

 

Thanks for your reply - I was getting a bit despondant and nearly gave up...

It's a while since I wrote this, so it's a bit rusty...  Things appeared to be going OK in DNN, jsut that the image never got updated.  If you can find the flaws in this, or could provide a working example, I would be thrilled!!!

 

I created a control: SlideShowControl.ascx

 

<%

@ Control Language="C#" AutoEventWireup="true" CodeFile="SlideShowControl.ascx.cs"

 

<%

Inherits="DotNetNuke.Modules.AJAXControlToolkit.AJAXControlToolkit" %>@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="cc1" %>

<

<

br />asp:UpdatePanel ID="UpdatePanel1" runat="server">

 

<ContentTemplate>

 

 

<asp:Image ID="Image1" runat="server" Height="316px" Width="388px"ImageUrl="~/images/Blue hills.jpg" /><br />

 

<br />

 

<asp:Label ID="lblImageDescription" runat="server" /><br />

 

<br />

 

<asp:Button ID="Btn_Previous" runat="server" Text="Previous" />

 

<asp:Button ID="Btn_Next" runat="server" Text="Next" Width="64px" /><br />

 

<br />

 

<asp:Button ID="Btn_Play" runat="server" Text="Play" /><br />

 

<cc1:SlideShowExtender ID="SlideShowExtender1" AutoPlay="true" ImageDescriptionLabelID="lblImageDescription"

 

Loop="true" NextButtonID="Btn_Next" PlayButtonID="Btn_Play" PlayButtonText="Play"

 

PreviousButtonID="Btn_Previous" SlideShowServiceMethod="GetSlides" StopButtonText="Stop"

 

TargetControlID="Image1" runat="server" SlideShowServicePath="SlideShowService.asmx">

 

</cc1:SlideShowExtender>

 

</

</ContentTemplate>asp:UpdatePanel>

 

 

and the code behind...

 

using

ScriptManager objScriptManager = ScriptManager.GetCurrent(this.Page);// Add a reference to the web service

 

objServiceReference.Path =

objScriptManager.Services.Add(objServiceReference);

}

}

}

}

 

 

and the slide show service...

Hi,

no - this never worked.  It seemed that the images were being supplied correctly from the web service, but the displayed image never changed.  The same code ( .asx component) worked ok in Visual studio though...
