How to give the DataTextField and DatavalueField for a CheckBoxList nested inside a Repeater?

My repeater control is given below..but it is not working..please help me

<asp:Repeater runat="server" ID="rptCategories">
    <HeaderTemplate>
     </HeaderTemplate>
    <itemtemplate>
    <asp:CheckBoxList ID="CheckBoxList1" runat="server" DataSource='<%# ((System.Data.DataRowView)Container.DataItem).Row.GetChildRows("CategoryToMenu") %>' DataTextField='<%# DataBinder.Eval(Container.DataItem, "[\"ItemName\"]")%>' >
               < /itemtemplate>
</asp:Repeater>

推荐答案

使用Repeater的ItemDataBound事件，如下所示：

Use the ItemDataBound event of the Repeater, like this:

protected void rep_Comps_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
    CheckBoxList chkList = e.Item.FindControl("chk_chkbx") as CheckBoxList ;
    if (selectList != null)
    {
        chkList.DataSource = SomeDataSource();
        chkList.DataBind();

        chkList.DataTextField = "SomeColumn";
       chkList.DataValueField = "SomeID";
    }
}
