请帮我这样做





我使用转发器控件显示菜单，但它在主页面中没有显示任何内容

How can we Display menu items dynamically in master page from database in asp.net?

please help me to do this


Im using repeater control for displaying menu but it doesn't show anything in master page

<asp:Repeater ID="rptrmenu" runat="server">
               <ItemTemplate>

                   <li><a style="color:White " id='<%#Eval("menu_id ")%>' class="aTab" >

                      <%#Eval("menu_name ")%></a></li>

{
   if (!IsPostBack)
   {
      BindRepeaterData();
   }
}

public void BindRepeaterData()
{
   Con1.SetConnection();
   StrQry = new StringBuilder();
   StrQry = new StringBuilder();
   StrQry.AppendFormat("select a.Menu_Id,a.Menu_Name from EGP_MstMenu a inner join EGP_UserGroupMenu b on a.menu_id=b.menu_id  ");
   da = new OleDbDataAdapter(StrQry.ToString(), Con1.Con);
   DataSet ds = new DataSet();
   Repeater rptrmenu = new Repeater();
   da.Fill(ds);
   if (ds.Tables[0].Rows.Count > 0)
   {
      rptrmenu.DataSource = ds;
      rptrmenu.DataBind();
   }
}

推荐答案

根据您在问题中发布的代码，代码中似乎没有问题，但请检查您的表是否返回任何值。但是在评论中提到的代码中你提到的位置有错误：

As per code you posted in your question, there seems no issue in code, But check if your table returning any value or not. But in the code mention in comment you have error in position as mentioned:

<asp:Repeater ID="rptrmenu" runat="server">


                    <li>

                       <%#Eval("menu_name ")%></li>
