问题描述

我有管理面板，因为我有一个页面是adoutUs，页面设计为id，每次使用单个id的文本时我都必须更新文本，但是在前端，我有显示管理面板文本数据，但它显示所有数据交叉设计，所以我想放置链接按钮，即ReadMore，我该如何放置以及如何将下一个数据提供给ReadMore链接按钮(在这里，我面临的问题是后端文本数据​​显示不完整，所以我想让数据阅读更多按钮)请任何人知道帮助我

推荐答案

检查此脏代码.

Check this dirty code.

//get your data from db to a string.
string strTemp = "I have admin panel in that i have one page that is adoutUs that page design is id,text i have to update every time text with single id,but in front-end i have display admin pannel text data, but ";
//check fot number of characters you want to display before read more
if (strTemp.Length > 100)
           {
               if (strTemp.IndexOf(' ', 100) != -1)
               {
                  string  stripped = Regex.Replace(strTemp, @"<(.|\n)*?>", string.Empty);
   //you can redirect using id as query string                
 stripped = stripped.Substring(0, stripped.IndexOf(" ", 50)) + " <a href='default.aspx?redirect=yes'>Read More</a>";                 
                    Label1.Text = stripped;
               }
               else
               {
                  Label1.Text = strTemp;
               }
//check for the query string value.
if (Request.QueryString["redirect"] == "yes")
            {
                Label1.Text = strTemp;//Response.Write(strTemp);
            }

如果您使用中继器来绑定用户端的数据，则可以使用以下代码:

If you are using a repeater for binding the data from user end, you can use the following :

private void dataList_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)
{
      if( (e.Item.ItemType == ListItemType.Item) || ( e.Item.ItemType == ListItemType.AlternatingItem))
      {
            HyperLink hyplnk = (HyperLink)e.Item.FindControl("lnkReadmore");
            if (hyplnk.Text.length > 20 )
            {
                 hyplnk.Text = hyplnk.Text.Substring(0,20);
            }
      }
}
