不知道什么原因，在Datalist下面的LinkButton控件到后台就不能识别了?
<asp:DataList ID="dlFree" runat="server" RepeatColumns="1 "
onselectedindexchanged="dlFree_SelectedIndexChanged">
<ItemTemplate>
<table border="1px">
<tr>
<td>
<a href="javascript:window.location.href='showimage.aspx?id='+<%#DataBinder.Eval(Container.DataItem, "Mid ")%>">
<img style="border: 6px solid #ffffff; width: 200px; height: 200px;" alt="<%#DataBinder.Eval(Container.DataItem, "Title1 ")%>"
src='<%# DataBinder.Eval(Container.DataItem,"Photopath") %>' /></a>
</td>
<td>
<table style="width: 250px; font-size:12px;">
<tr>
<td>
<asp:LinkButton ID="LinkButton1" runat="server" >收录</asp:LinkButton>
</td>
</tr>
</table>
</td>
</tr>
</table>
</ItemTemplate>
</asp:DataList>

不知道什么原因，在Datalist下面的LinkButton控件到后台就不能识别了.....
有解决方法吗?

[解决办法]
因为你这个linkbutton控件是在datalist里面的，必须要通过datalist事件来获取

C# code

protected   void   DataList1_ItemDataBound(object   sender,   DataListItemEventArgs   e)         {                 LinkButton   link   =   (LinkButton)e.Item.FindControl( "link1 ");                 //这里就获取到了link        }
[解决办法]
也可以这样

protected   void   DataList1_ItemDataBound(object   sender,   DataListItemEventArgs   e)  
       {  
               LinkButton   link   =   e.Item.FindControl( "link1 ") as LinkButton;  
       }

探讨


也可以这样

protected   void   DataList1_ItemDataBound(object   sender,   DataListItemEventArgs   e) 
        { 
                LinkButton   link   =   e.Item.FindControl( "link1 ") as LinkButton; 
……

[解决办法]
加个判断可能好点

   protected void DataList1_ItemDataBound(object sender, DataListItemEventArgs e)
       {
           if(e.Item.ItemType==ListItemType.Item)
           {
                LinkButton link = e.Item.FindControl( "link1 ") as LinkButton;  
           }
       }
   
 } 

[解决办法]
<asp:LinkButton ID="LinkButton1" CommandName="sl" CommandArgument='传入阐述' runat="server" >收录</asp:LinkButton>

protected void DataList1_RowCommand(object sender, GridViewCommandEventArgs e)
{
    if (e.CommandName == "sl")
    {
        //执行点击事件
        Response.Write(e.CommandArgument);//输出传入的参数
    }
}
[解决办法]
HTML code
 <asp:LinkButton ID="LinkButton1" runat="server" CommandArgument='<%#Eval("ID") %>' onclick="LinkButton1_Click">LinkButton</asp:LinkButton>
