ImageButton不会在中继器控制中触发OnItemCommand

大家！我正在写网页上的中继器控制。在我为中继器添加数据分页之后，我遇到了问题： ImageButton不再触发中继器的OnItemCommand事件。为什么？ImageButton不会在中继器控制中触发OnItemCommand

这里，是标记代码部分：

<asp:Repeater ID="PartsRepeater" runat="server" 
        OnItemCommand="partsRepeater_ItemCommand" 
        OnItemDataBound="partsRepeaterItem_Bound"> 
        <HeaderTemplate> 
         <table rules="all" cellspacing="0" style="border-color: rgb(31, 77, 48);

          <tr > 
           <td style="width: 92%;"> 
            <table cellspacing="0" border="0" style="border-color: rgb(31, 77, 48); border-style: solid;

我已经试过NANY的方式来解决这个问题并解决它，以便：我只是用的LinkButton图像替换的ImageButton：部分OG代码：

<td style="cursor: pointer; width: 50%;" class="PartsRepeater_InnerTable"> 
              <asp:LinkButton ID="btnEdit" runat="server" CausesValidation="false" CommandName="editRow" 
               CommandArgument='<%# Eval("PartID") %>' OnClientClick='SaveScrollPositions'> 
               <asp:Image ID="Image1" runat="server" ImageUrl="~/Images/edit.png" /> 
              </asp:LinkButton> 
             </td> 
             <td style="cursor: pointer; width: 50%;"> 
              <asp:LinkButton ID="btnDelete" runat="server" CausesValidation="false" CommandName="Delete" 
               CommandArgument='<%# Eval("PartID") %>' OnClientClick='<%# GetConfirmMessage(Eval("Name"))%>'> 
               <asp:Image ID="Image2" runat="server" ImageUrl="~/Images/delete.png" /> 
              </asp:LinkButton> 
             </td>

对不起，我没有更具体的答案，但它有somethi与中继器上的ViewState配合使用，并在回发中重新绑定中继器。

显然，当发生回发并重新绑定中继器时，它会丢失一些事件绑定，而不是运行OnCommand，它会将它视为是ImageButton的首页加载。 AFAIK它只发生在ImageButton上，而不是LinkButton或Button。

把这个在它后面的代码一定会努力

if (!Page.IsPostBack) 
{ 
    REPEATERDATABIND(); // Bind method 
}
