如何使用Asp.Net Ajax SlideControl加载图像? [英] How to load images using Asp.Net Ajax SlideControl?

问题描述

大家好！

我写了这段代码:

Hello Every one!

I wrote this code:

<asp:ScriptManager ID="Sm1" runat="server">
        </asp:ScriptManager>
        <br />
        <asp:Image ID="Image1" runat="server" Height="316px" Width="388px" ImageUrl='<%# "Photo_Handler.ashx?ph_id="+Eval("AlbumId")%>' /><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 />
        <asp:SlideShowExtender ID="SlideShowExtender1" runat="server" AutoPlay="true" ImageDescriptionLabelID="lblImageDescription"

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

            PreviousButtonID="Btn_Previous" StopButtonText="Stop" TargetControlID="Image1"

            SlideShowServiceMethod="GetSlides">

        </asp:SlideShowExtender>

在这里，我尝试使用Asp.Net Ajax幻灯片放映控件.我正在从数据库加载图像.如何绑定图像?
这里的webService方法是这个

Here i am trying to use Asp.Net Ajax Slide Show Control. I am loading the images from database. How to bind the images?
Here the webService method is this

public static  AjaxControlToolkit.Slide[] GetSlides( int id)
    {
        int size;
        OURKUTEntities oe=new OURKUTEntities();//this is the Entity name
        var get_pics = oe.Photos.Where(i => i.AlbumId == id).ToList();//Here am geting the Photos from PHOTOS Table
        size = get_pics.Count;
        AjaxControlToolkit.Slide[] slide = new AjaxControlToolkit.Slide[size];
        int j = 0;
        foreach (var item in get_pics)
        {
            if (size != j)
            {
                var photocontent = item.Photo_Content;
                string s = Convert.ToString(photocontent);
                slide[j] = new AjaxControlToolkit.Slide(s, item.PhotoName, item.Photo_Type);
                j++;
            }
        }
        return (slide);
    }

推荐答案

最明显的方法是拥有一个带有ID的网页，以从数据库返回图像，然后将这些URL用于您的幻灯片放映控件.

The most obvious way is to have a web page that takes an id to return an image from the DB, then use those URLs to your slideshow control.
