AJAX :: Toolkit Slideshow Extender's Webservice - Set Up The Slide Show Based On A Querystring Parameter
Oct 19, 2010
I need to set up the slide show based on a querystring parameter. I thought I had this figured out, but I clearly don't understand something about how the webservice works. I have this in the .aspx page:
<asp:Button ID="btnPrev" runat="server" Text="Prev" />
<asp:Button ID="btnPlay" runat="server" Text="Play" />
<asp:Button ID="btnNext" runat="server" Text="Next" />
<asp:Label ID="lblDesc" runat="server" />
<cc1:SlideShowExtender ID="SlideShowExtender1" runat="server" BehaviorID="SSBehaviorID"
TargetControlID="tstSlides"
AutoPlay="true"
ImageDescriptionLabelID="lblDesc"
NextButtonID="btnNext"
PreviousButtonID="btnPrev"
PlayButtonID="btnPlay"
PlayButtonText="Play"
StopButtonText="Stop"
Loop="true" >
</cc1:SlideShowExtender>
<asp:Image ID="tstSlides" runat="server" height="300px" Width="300px" />
And this in the code behind:.........................

I have used a ajax control toolkit slide shox extender to display a slide show of images.
Currently, when a user hovers mouse over the slide show, the slide keeps on changing. I want that the slide should not change, if a user hovers the mouse.

An Ajax Toolkit SlideShow used to work in .NET 2.0. After being upgraded to 3.5 the same slideshow stops working as before. It always pops up "Object reference not set to an instance of an object.". Different rewrites cause different errors at embedded Jscript level that cannot be fixed. I have added the AjaxToolkit.dll 3.5 under bin folder and placed its items in the VS2008 toolkit.

I'm using visual studio 2010 and sql server 2008. I'm trying to use a web method to get urls from a database for an ajax slide extender control. I’ve been able to create a web method to call the slides and it worked. Then I wanted to create a parameter in my web method that took a parameter. I’ve been unable to get it to work with the parameter with the web method. I’m either using the wrong syntax when calling the parameter or my web method is incorrect.
This is the code for the web method with out parameter that works
Code:
<WebMethod()> _
Public Function GetSlidesDBGalEngage() As AjaxControlToolkit.Slide()
Dim connetionString As String
Dim connection As SqlConnection
Dim command As SqlCommand
[Code] ....
This is the way I calling the web method in my extender that works
HTML Code:
<cc1:SlideShowExtender ID="SlideShowExtender1" runat="server" AutoPlay="True"
ImageDescriptionLabelID="label1" NextButtonID="btnNext"
SlideShowServiceMethod="GetSlidesDBGalRecept" SlideShowServicePath="../SlideService.asmx"
PlayButtonID = "btnPlay" PreviousButtonID="btnPrev"
TargetControlID="image1">
</cc1:SlideShowExtender>
This is my web method which has a paramater
Code:
<WebMethod()> _
Public Function GetSlidesDBGalEngage(ByVal Category As String) As AjaxControlToolkit.Slide()
Dim command As SqlCommand
Dim adapter As New SqlDataAdapter
[Code] ....
This is how I'm trying to call the web method with paramater from my slide extender which doesn't work
HTML Code:
<cc1:SlideShowExtender ID="SlideShowExtender1" runat="server" AutoPlay="True"
ImageDescriptionLabelID="label1" NextButtonID="btnNext"
[B]SlideShowServiceMethod="GetSlidesDBGalParm("Other")"
[I]I've tried using both single qoutes and double quotes and notheing works[/I].[/B]
SlideShowServicePath="../SlideService.asmx"
PlayButtonID = "btnPlay" PreviousButtonID="btnPrev"
TargetControlID="image1" ClientIDMode="AutoID">
</cc1:SlideShowExtender>
Something is wrong with the syntax in the web method with the paramter or something is wrong with the way I'm calling it .

The Slideshow isnt looping, however, it appears that the page is trying to refresh itself for each loop interval (I can see this at the bottom: downloading ...)
This should work because Im basically used the same code thats in the demo, minus the labels and buttons, and modified the web.config to be identical as well.

Here is the web.config:

I'm using the Slideshow extender and have a vexing problem that I can't see to solve. The slidehow itself works fine, but I am trying to get the value of the ImageDescriptionLabelID into a javascript variable when the slide changes. Using this code in a javascript function:
[Code]....
It appears that the add_slideChanging event fires BEFORE the image (and accompanying label) change. Is there an event that occurs AFTER the image changes?If not, any ideas on how I can make the number I'm successfully passing in the lblDesc control available to javascript?

I have found all kinds of tutorials on the web showing how to implement the AJAX slideshow extender, but can't get them to work. All I want to do is put a simple slideshow on a master page. I want to use a code behind file for the c# (do not want the script on the page itself.
I ran into a couple of problems with the samples on the web. Specifically when I try to add System.Web.Services.WebMethod and System.Web.Script.Services.ScriptMethod - VS 2010 doesn't know what the "WebMethod" or the "ScriptMethod" are. Further, VS2010 express keeps telling me "{" expected - on the line AjaxControlToolkit.Slide[] slides = new AjaxControlToolkit.Slide[5];
Every tutorial on the web seems to be for ASP.net 2.0 - and is at least 2 years old. Is there an easier way in ASP.Net 4 to implement the slideshow control? I am new to c# in general, so if someone could provide a simple cs codebehind file - and the code on the aspx page, that would be great. I understand more than I can write.

I have a slideshow extender, I will change the slideshow extender's contextkey value by a button click event. So that after button click the slideshow will display different set of image. Originally with postback everything work fine, but I don't want the whole page to refresh.
So I put the slideshow extender inside an updatepanel with triggers target the button click event. Now the whole page didn't refresh and the slideshow extender's contextkey value did change (same code as before) after button click event. However the image set on the slideshow didn't change.
I think I am missing some sort of slideshow extender reload or refresh call but I am not sure how to do this? I didn't see any related property with slideshow extender...

but when i publish the site I have JScript Error and Slideshow Extender not be loaded.

I have this slideshow extender that works perfectly with hard coded images in the page method. However as soon as I try to make the page method get its images from the database it stops working; no images are returned.
I have tried to declare the datatable that the pagemethod uses both inside the pagemethod and in the on_load event. When in the last case I test the datatable contents by hooking it up to a gridview, it shows that it does get its proper data.
Declaring this dataTable as a private static dataTable, outside the page_load, to make it accessible in the page method (like in this --- post http://forums.asp.net/p/1115257/1726736.aspx---) also does not work.
So the page method with hard coded images works and also the query to the database works!

My slideshow extender work perfectly fine, but I want to retrieve the current display picture's information on the server side.
So I added a normal asp button on the same page as the slideshow extender. When button clicked, it fire off a server side function. In the function I grabbed the SlideShow's name label, description label or the Image, but none of them contain any current information of the picture displayed at slideshow extender.
Is there another way to obtain the slideshow extender current state? Or am are those name, description label text value should be updated?
