下面是控件后台和一个图片类的代码:
- public partial class WebParts_PicList : System.Web.UI.UserControl
- {
- protected void Page_Load(object sender, EventArgs e)
- {
- ShowImages();
- }
- public void ShowImages()
- {
- for (int i = 0; i < ListImages.Count; i++)
- {
- //标题和小图
- if (i == 0)
- {
- urImgTitle.InnerHtml += "<li class='current'>" + listImages[i].ImageTitle1 + "</li>";
- ulImgSmall.InnerHtml += "<li class='current'><img src='" + listImages[i].ImageSrc1 + "' alt='" + listImages[i].ImageAlt1 + "' /></li>";
- }
- else
- {
- urImgTitle.InnerHtml += "<li class='normal'>" + listImages[i].ImageTitle1 + "</li>";
- ulImgSmall.InnerHtml += "<li class='normal'><img src='" + listImages[i].ImageSrc1 + "' alt='" + listImages[i].ImageAlt1 + "' /></li>";
- }
- //大图
- ulImgBig.InnerHtml += " <li><a href=" + listImages[i].ImageHref1 + " target='_blank'><img src=" + listImages[i].ImageSrc1 + " alt=" + listImages[i].ImageAlt1 + " border='0' /></a></li>";
- }
- }
- private List<ShowImages> listImages;
- public List<ShowImages> ListImages
- {
- get { return listImages; }
- set { listImages = value; }
- }
- }
- //图片的属性
- public class ShowImages
- {
- string ImageSrc;
- string ImageHref;
- string ImageTitle;
- string ImageAlt;
- public string ImageAlt1
- {
- get { return ImageAlt; }
- set { ImageAlt = value; }
- }
- public string ImageSrc1
- {
- get { return ImageSrc; }
- set { ImageSrc = value; }
- }
- public string ImageHref1
- {
- get { return ImageHref; }
- set { ImageHref = value; }
- }
- public string ImageTitle1
- {
- get { return ImageTitle; }
- set { ImageTitle = value; }
- }
- }
实现思路是 ShowImages的集合当作控件的一个属性.然后便利集合循环赋值.
下面是页面调用的代码:
复制代码代码如下:
List<ShowImages> listImages = new List<ShowImages>();
ShowImages image1 = new ShowImages();
image1.ImageAlt1 = "喵喵";
image1.ImageHref1 = "//www.zzvips.com";
image1.ImageSrc1 = "http://b23.photo.store.qq.com/http_imgload.cgi?/rurl4_b=e52b4cc5fe67c1a2dc328adb766f1633bfc02bb27fe17aa21ca1264a0dac599fc425faf65d1daac8ab7cb5923a15443882d9d0586694a0e5eb0671af60a2f6e739d3c15b1e52f2c518a00344fa791dbaee88cc43&a=25&b=23";
image1.ImageTitle1 = "这是我的自画像";
listImages.Add(image1);
listImages.Add(image2);
listImages.Add(image3);
listImages.Add(image4);
PicList1.ListImages = listImages;
ok 一个简单的控件就实现了
