您将需要使用 jquery 添加一些客户端脚本。
这是如何做到的:
在您的 .aspx 中将转发器定义为:
<asp:Repeater ID="rpt" runat="server">
<ItemTemplate>
<div class="divItem" id='divItem<%# Eval("ID") %>'>
<asp:HiddenField ID="hfSelected" runat="server" />
<asp:HiddenField ID="hfIID" runat="server" Value='<%# Eval("ID") %>' />
<asp:Image ID="imgItem" runat="server" ImageUrl='<%# Eval("ImageURL") %>' />
<asp:Label ID="lblName" runat="server" Text='<%# Eval("ItemName") %>'></asp:Label>
</div>
</ItemTemplate>
</asp:Repeater>
然后添加这个javascript:
<script>
$(function () {
$('.divItem').click(function () {
var item = $(this);
item.toggleClass("divItemSelected"); //mark div as selected: set background color, etc...
var selector = "#" + item.attr("id") + " input[type='hidden'][id*='hfSelected']";
var selected = $(selector).val();
if (selected == "true") {
$(selector).val("false");
} else {
$(selector).val("true");
}
});
});
</script>
然后在按钮单击的代码隐藏中,执行以下操作:
protected void OnSaveClick(object sender, EventArgs e)
{
foreach (RepeaterItem item in rpt.Items)
{
HiddenField hfSelected = item.FindControl("hfSelected") as HiddenField;
bool selected = false;
bool.TryParse(hfSelected.Value, out selected);
if (selected)
{
HiddenField hfIID = e.Item.FindControl("hfIID") as HiddenField;
int id = Convert.ToInt32(hfIID.Value);
// do appropriate action as needed.
}
}
}
希望这可以帮助!
