JS DataList CheckBox与CheckBoxList联动。
代码如下：
<asp:DataList ID=dlGroup runat=server onitemdatabound="dlGroup_ItemDataBound">
<ItemTemplate>
<asp:CheckBox ID=ckGroup runat=server Text='<%# DataBinder.Eval(Container.DataItem,"GroupName") %>' onclick= JS方法/>
<asp:HiddenField ID=hidGroupTimePK runat=server Value='<%# DataBinder.Eval(Container.DataItem,"TimePK") %>' />
<asp:CheckBoxList ID=ckPsn runat=server RepeatColumns=8></asp:CheckBoxList>
</ItemTemplate>
</asp:DataList>
我的想法是通过JS 选择CheckBox时，和它一级的 CheckBoxList全选择，否则取消。
[解决办法]
protected void dlGroup_ItemDataBound(object sender, DataListItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.AlternatingItem || e.Item.ItemType == ListItemType.Item)
{
CheckBox ckGroup = e.Item.FindControl("ckGroup") as CheckBox;
CheckBoxList ckPsn = e.Item.FindControl("ckPsn") as CheckBoxList;
ckGroup.Attributes.Add("onclick", "SetNext(this,'" + ckPsn.ClientID + "')");
}
}
