Question

当用户单击linkButton OnItemCommand时，不会触发。从不调用ItemCommand事件。该代码运行并生成div并显示正确的数据，因此我知道此人对象已正确绑定，但是单击链接按钮不起作用，因为从不触发MatchList_ItemCommand。

我一直在搜索几天，但是遇到的任何事情都无法为我解决此问题。我没发现这段代码有什么问题。

(dataGridView1.DataSource as DataTable).DefaultView.RowFilter = string.Format("Name LIKE '%{0}%' OR ID LIKE '%{0}%'", searchTextBox.Text);

<asp:Panel ID="matchListPnl" runat="server" Visible="false">

       <h1>Look Up Person: Results</h1>
       <p><asp:Label ID="matchListLbl" runat="server"></asp:Label> Clicking the name loads it for administration.</p>

       <asp:Panel ID="exactMatchPnl" runat="server" Visible="false">       
          <h2><asp:Label ID="exactMatchLbl" runat="server"></asp:Label></h2>
          <asp:Repeater ID="exactMatchList" runat="server" OnItemCommand="MatchList_ItemCommand"/>

OnItemCommand不在中继器中触发
