大家好! 我正在我的网页上编写中继器控件。在我为中继器添加数据分页后，我遇到了问题: ImageButton 不再触发中继器的 OnItemCommand 事件。为什么？
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);
border-style: solid; width: 100%; border-collapse: collapse;">
<tr >
<td style="width: 92%;">
<table cellspacing="0" border="0" style="border-color: rgb(31, 77, 48); border-style: solid;
width: 100%; border-collapse: collapse;">
<tr style="background-color: #1f4d30; color: white;">
<td style="width: 10%;">
<asp:Label runat="server" Text="Name" ID="lblName">

最佳答案
我已经尝试了很多方法来解决这个问题并解决了: 我只是将 ImageButton 替换为 linkButton 和图像: 部分代码:
<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>
