大家好！ 我在我的网页上写了转发器控件。在我为转发器添加数据分页后，我遇到了问题： ImageButton不再触发转发器的OnItemCommand事件。为什么呢？
这里是标记代码的一部分：
<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);

我尝试了很多方法来解决这个问题，并解决了这个问题： 我只是用linkButton替换ImageButton和image： 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>

抱歉，我没有更具体的答案，但它与转发器上的ViewState有关，并在Postback上重新绑定转发器。
显然，当回发发生并重新绑定转发器时，它会丢失一些事件绑定，而不是运行OnCommand，它会将其视为ImageButton的第一页加载。 AFAIK它只发生在ImageButton而不是LinkButton或Button。

把它放在它背后的代码中肯定会有用
if (!Page.IsPostBack)
{
REPEATERDATABIND(); // Bind method
}
