有两个CheckBox,一个在外部Repeater中,另一个在内部Repeater内。
我想在检查外部Repeater的CheckBox时自动检查内部Repeater的CheckBox。
HTML标记:
<asp:Repeater ID="repOuter" runat="server">
<ItemTemplate>
<asp:CheckBox ID="chkOuter" runat="server"
OnCheckedChanged="chkOuter_CheckedChanged" />
<asp:Repeater ID="repInner" runat="server">
<ItemTemplate>
<asp:CheckBox ID="chkInner" runat="server" />
</ItemTemplate>
</asp:Repeater>
</ItemTemplate>
</asp:Repeater>
代码隐藏
protected void chkOuter_CheckedChanged(object sender, EventArgs e)
{
// can't have access to inner CheckBox placed inside Inner Repeater
CheckBox innerCheckBox; // how?
innerCheckBox.Checked = true; // want to check it
}

你可以尝试这个(虽然未经测试)。
CheckBox chkOuter = (sender as CheckBox);
RepeaterItem item = (RepeaterItem)chkOuter.NamingContainer;
Repeater rp = item.FindControl("repInner") as Repeater;
foreach (RepeaterItem item in rp.Items)
{
(item.FindControl("chkInner") as CheckBox).Checked = chkOuter.Checked;
}
