AJAX :: SlideShow Extender - Page Method Can't Get Its Slides From Database?
Mar 8, 2010
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!
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.
I'm using ajax slideshow extender for a slideshow. How do I use an imagebutton to play/pause slideshow. I would have to change the imageurl with the corresponding action...
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?
what i am trying to achieve is a single image control with slideshow extender attached which when of the category option buttons are pressed the SlideService goes get the images for that category from the image folder sub folders and starts to display them i have got the code to work as to, the point that i have to hardcode the images sub folders path in to the webmethod - but i want the image folder name to be passed as a parameter when the webmethod GetSlides is called - the code i have so far is From the aspx page - (the category name will be a string retrieved from the button text when clicked
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...
when I run my site that used Slideshow Extender, i get this Error:
Microsoft JScript runtime error: Sys.InvalidOperationException: Can't add a handler for the error event using this method. Please set the window.onerror property instead.
in localhost i ignore this Error and Slideshow Extender works correct.
but when i publish the site I have JScript Error and Slideshow Extender not be loaded.
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?
i have developed a AutoComplete Search with the JAX AutoCompleteExtender Now i found a solution to use these control without a webservice (amsx) you only have the function in the codebehind (default.aspx.cs) , to do this you must let theServicePath empty. In the codebehind of your webpage is only the function which gets the data from the database.Important the function must be static !!

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:
I would like to use the ajax slideshow extender and getting the Image Url stored in a databaseso far my webserivice look like this..but I think im making a mistake somewhere..its not working
<WebMethod()> _ Public Function GetSlides() As AjaxControlToolkit.Slide() Dim Connection As SqlConnection
I've watched the Slideshow videos and created a number of examples that run fine. The code I've attached at the bottom is the smallest one, but instead of hard coding the image locations, I would like to select the slides from either of the following statements, which return the top 5 images selected randomly from our floorplans database.
<asp:AccessDataSource id="AccessDataSource1" runat="server" DataFile="../fpdb/J3_2005.mdb" SelectCommand="SELECT TOP 5 [Elev_Pimage] FROM [PLANS_Active] ORDER BY RND(INT(NOW*[SF_Total])-NOW*[SF_Total])" /> or,
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:J3_2005Slideshow %>" ProviderName="<%$ ConnectionStrings:J3_2005Slideshow.ProviderName %>" SelectCommand="SELECT TOP 5 [Elev_Pimage] FROM [PLANS_Active] ORDER BY RND(INT(NOW*[SF_Total])-NOW*[SF_Total])" /> <title>SlideShow</title>

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
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 .
I have AutocompeteExtender control in my page.it calls web method (in webservice) that have no parameter I have two web methods in webservice Method 1Geist(string PreText, int Count){....}Method 2GetList(){.......}ethod 2 calls.I want to call method 1.
