After I have removed the paramter from page_load, I am still getting this error:

<title>The HTTP verb POST used to access path '/IwantIoffer/ShowAd.aspx/GetSlides' is not allowed.</title>

I have just realized it missed the /localhost in the path. Any idea??? It should be "http://localhost/IwantIoffer/ShowAd.aspx/GetSlides'

I wonder if thsi is causing the problem. I have this in page_load:

slideshowextender.SlideShowServiceMethod = "GetSlides?AdID=" + adIdQs;

Also This does not look like a valid URL: http://localhost/IwantIoffer/ShowAd.aspx/GetSlides?AdID=49245. Why is it generated in this form???

Server Error in '/IwantIoffer' Application.

The resource cannot be found.

Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly.

Requested URL: /IwantIoffer/ShowAd.aspx/GetSlides

Version Information: Microsoft .NET Framework Version:2.0.50727.1433; ASP.NET Version:2.0.50727.1433

However when I run the same URL on the live server: http://www.zikbay.com/ShowAd.aspx/GetSlides?AdID=49245, it goes to Search.aspx. The only reason for this can be that it is hitting Page_load of Show.aspx with no parameter called "ID"....

Here is my code:

Here is GetSlides method: class="coloredcode">1 <asp:Panel ID="PhotoPanel" runat="server" Visible="False"> <p class="notice"> <asp:LinkButton ID="HidePhotoPanel" runat="server" OnClick="HidePhotoPanel_Click">Hide again</asp:LinkButton></p> <div style="text-align: center"> <p> <%-- <asp:ImageButton ID="FullSizePhoto" runat="server" OnClick="FullSizePhoto_Click" AlternateText="Show other ad photos if they exist." />--%> <asp:Image ID="FullSizePhoto" runat="server" Style="border: 1px solid black; width: auto" AlternateText="Ad Photo" /> <asp:Label runat="Server" ID="imageLabel1" /><br /> <br /> <asp:Button runat="Server" ID="prevButton" Text="Prev" Font-Size="Larger" /> <asp:Button runat="Server" ID="playButton" Text="Play" Font-Size="Larger" /> <asp:Button runat="Server" ID="nextButton" Text="Next" Font-Size="Larger" /> </p> <%-- <asp:Image ID="Image1" runat="server" Height="300" Style="border: 1px solid black;width:auto" ImageUrl="~/slideshow/images/Blue hills.jpg" AlternateText="Blue Hills image" />--%> <ajaxToolkit:SlideShowExtender ID="slideshowextender" runat="server" TargetControlID="FullSizePhoto" SlideShowServiceMethod="GetSlides" AutoPlay="true" ImageDescriptionLabelID="imageLabel1" NextButtonID="nextButton" PlayButtonText="Play" StopButtonText="Stop" PreviousButtonID="prevButton" PlayButtonID="playButton" Loop="true" /> </div> </asp:Panel>

Check your server mapping - the error indicates that there's a problem resolving the url to the webservice... "/ShowAd.aspx/GetSlides?AdID=49245 is not a valid virtual path."

Re: SlideShowExtender and database integration, c# newbie

rfurdzik — Mon, 31 Mar 2008 02:24:44 GMT

After upgrade to 3.5 it does not work anymore, please see the error here (click on any image): http://www.zikbay.com/Ad/49245

Any idea what is causing this??? It is the same code I placed above...

Thanks so much for your post, Marcel (Aug of 2006). It was a long time ago, but your method worked for me - I've been looking all over on how to get a parameter passed to the GetSlides() method. I couldn't get the contextkey to work, so this was a great solution; thank you!

Re: Problems with Slide Control

rfurdzik — Fri, 06 Jul 2007 00:35:45 GMT

OK, the full path works fine, you guys still should fix the relative path problem with URL rewriter...

public static AjaxControlToolkit.Slide[] GetSlides()

{

// Check if the URL querystring contains a valid ad.

int aid = DefaultValues.IdNullValue;

string adIdQs = HttpContext.Current.Request.QueryString["AdID"];

if (adIdQs != null && !Int32.TryParse(adIdQs, out aid))

{

HttpContext.Current.Response.Redirect("~/Search.aspx");

}

//int aid = 121; //hardcoded value just for testing

//int aid = AdId; //This wan't work as the webservice MUSt be static and AdId is Instance method..

AdsDataComponent.PhotosDataTable dreImages = PhotosDB.GetPhotosByAdId(aid) as AdsDataComponent.PhotosDataTable;

//AjaxControlToolkit.Slide mySlides = new AjaxControlToolkit.Slide();

AjaxControlToolkit.Slide[] mySlides = new AjaxControlToolkit.Slide[dreImages.Count];

// ArrayList myList = new ArrayList();

//int i;

//for(i=0; i<5; i++)

// myList.Add(i);

//myList.Add("Hello");

//for(i=0; iConsole.WriteLine("Array Index [{0}]: {1}", i, myList[i].ToString());

if (dreImages != null)

{

int i = 0;foreach (AdsDataComponent.PhotosRow photo in dreImages)

{

StringBuilder ImageUrl = new StringBuilder();

if (ClassifiedsHttpApplication.SiteUrl != null)

{

ImageUrl.Append(ClassifiedsHttpApplication.SiteUrl);

if (!ClassifiedsHttpApplication.SiteUrl.EndsWith("/"))

ImageUrl.Append("/");ImageUrl.Append("PhotoDisplay.ashx?size=full&photoid=");

ImageUrl.Append(photo.Id.ToString());

}

//string ImageUrl = "PhotoDisplay.ashx?size=full&photoid=" + photo.Id.ToString();

mySlides[i] =

new AjaxControlToolkit.Slide(ImageUrl.ToString(), "Image 1", "Image 1");

i++;

}

return mySlides;

// return new AjaxControlToolkit.Slide[] {

// new AjaxControlToolkit.Slide("images/Blue hills.jpg", "Blue Hills", "Go Blue"),

// new AjaxControlToolkit.Slide("images/Sunset.jpg", "Sunset", "Setting sun"),

// new AjaxControlToolkit.Slide("images/Winter.jpg", "Winter", "Wintery..."),

// new AjaxControlToolkit.Slide("images/Water lilies.jpg", "Water lillies", "Lillies in the water"),

// new AjaxControlToolkit.Slide("images/VerticalPicture.jpg", "Sedona", "Portrait style picture")};

//}

}

David, thanks for your reply. OK, I was not sure if it supports. I will put the full path now and let you know if it works.

I have to find out first how to get the full path to my root directory in the webservice....

Re: Problems with Slide Control

David Anson — Thu, 05 Jul 2007 23:37:51 GMT

SlideShow seems to support full URLs in the Slide constructor. For example, if I add the following line to the GetSlides method in SlideShow.aspx (10618 release), I see the new image fine:

new AjaxControlToolkit.Slide("http://www.live.com/live/1.900.9.001/img/wl_jewel.gif", "Windows flag", "Windows flag"),

As such, if you return the URL-remapped paths to your images from your web service I'd expect it to work. Could you maybe try this again?

Re: Problems with Slide Control

rfurdzik — Thu, 05 Jul 2007 23:06:13 GMT

Thanks a lot. I will put this under a seperate thread.

Re: Problems with Slide Control

kirtid — Thu, 05 Jul 2007 22:59:41 GMT

I see. This deviates from the general question of the thread. I was referring to the earlier question of passing additional data to the webservice. I will point David to this thread since he knows more about url rewriting.

kirtid:

The SlideShow extender webservice now takes in additional context. If you take a look at the sample website demo we document that and there are examples in the SampleWebsite and Toolkit tests project that demonstrate how to use that parameter.

Thanks, a lot

I am not sure how this is an answer to my question. It seems that Slides extender is using original URL path, instead of the rewritten one. How sendding additional string parameter can help here? Is there a property I can set for the base URL, so it does not use the current original URL? It would be also nice if I can provide full URL to my pictures, but extender adds the base path (wrong) in the background.... Did you guys test it with URLRewriter?

This is what I currently get with Extender using URLRewriter:

1 Link: original Link: http://localhost/mysite/Ad/118 Rewritten link: http://localhost/mysite/ShowAd.aspx?id=118

2) Extender shows pictures as:http://localhost/mysite/Ad/PhotoDisplay.ashx?size=full&photoid=360; This is what ist should be: http://localhost/mysiste/PhotoDisplay.ashx?size=full&photoid=362

Here is my code just in case:

    [System.Web.Services.WebMethod]
    [System.Web.Script.Services.ScriptMethod]
    public static AjaxControlToolkit.Slide[] GetSlides()
    {

        // Check if the URL querystring contains a valid ad.
        
        int aid = DefaultValues.IdNullValue;
        string adIdQs = HttpContext.Current.Request.QueryString["AdID"];
        if (adIdQs != null && !Int32.TryParse(adIdQs, out aid))
        {
            HttpContext.Current.Response.Redirect("~/Search.aspx");
        }

        //int aid = 121; //hardcoded value just for testing
        //int aid = AdId; //This wan't work as the webservice MUSt be static and AdId is Instance method..

        AdsDataComponent.PhotosDataTable dreImages = PhotosDB.GetPhotosByAdId(aid) as AdsDataComponent.PhotosDataTable;
        AjaxControlToolkit.Slide[] mySlides = new AjaxControlToolkit.Slide[dreImages.Count];
       
         if (dreImages != null)
        {
            int i = 0;

            foreach (AdsDataComponent.PhotosRow photo in dreImages)
            {
                string ImageUrl = "PhotoDisplay.ashx?size=full&photoid=" + photo.Id.ToString();
               
                mySlides[i] =
                    new AjaxControlToolkit.Slide(ImageUrl, "Image 1", "Image 1");
                i++;
            }

        }

        return mySlides;

               

    }
}

Problems with Slide Control

rfurdzik — Thu, 05 Jul 2007 20:02:34 GMT

I had the same problem. Thaks for the fix. The problem is that the webservice is static and can not access properties from the instance of the page... Here is more info: http://west-wind.com/weblog/ShowPost.aspx?id=8282

Do you guys know how to change the full path of the pticture? The problem is that with UR Rerwiter this does not work at all! The Slides Extender adds path to the existing original path request instead of to the rewritten one! So I am getting this URL:

http://localhost/mysite/Ad/PhotoDisplay.ashx?size=full&photoid=375 instead of this one http://localhost/site/PhotoDisplay.ashx?size=full&photoid=375

It is using the source URL path! http://localhost/mysite/Ad/ It should use the rewritten one: http://localhost/mysite/
