在此我在Repeater控件中添加了一个DropDownList, 为此将一个DataTable分配为DataSource。如何编辑Repeater控件中的DropDown项目

但我想根据DataSource数据编辑DropDownList.Items。

意味着如果数据源将从1,2,3 给3个数据,则DropDownLidt有列表项,如果这是5则1,2,3,4,5这样

所以对于我必须使用哪个事件以及我应该写什么代码?

在你的Repeateritemdatabound,找到你的control,并绑定到一个数据库,或设置值,或任何你想要的,如下图所示:

protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e) 
     { 
      if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) 
      { 
       DataRowView row = e.Item.DataItem as DataRowView; 

       DropDownList dl = e.Item.FindControl("ddlCategory") as DropDownList; 
       dl.DataSource = CategoriesDataTable; 
       dl.DataTextField = "CategoryDescription"; 
       dl.DataValueField = "CategoryPK"; 
       dl.SelectedValue = row["CategoryFK"].ToString(); 
       dl.DataBind(); 
      }

protected void rpt_ItemDataBound(object sender, RepeaterItemEventArgs e) 
    { 
     if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) 
     { 
      int count = 0; 
      // set count = your datatable count 
      DropDownList ddl = (DropDownList)e.Item.FindControl("ddl"); 
      for(int i=1;i<=count;i++) 
      { 
       ddl.Items.Add(i.ToString());  
      } 

     } 
    }
