在repeater 的ItemDataBound的事件中，获取绑定列的值

protected void RpVoteManage_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
RadioButtonList rb = e.Item.FindControl("RadioButtonList1") as RadioButtonList;
HiddenField hfd = e.Item.FindControl("hfd1") as HiddenField;

// 方法2
string jx = DataBinder.Eval(e.Item.DataItem, "Jx").ToString();
if (jx.Trim().Length > 0)
{
rb.SelectedValue = jx;

}

// 方法1 用隐藏控件绑定值
//if (hfd.Value.Trim().Length > 0)
//{

// // rb.SelectedValue = hfd.Value.Trim();
// //ListItem lt=new ListItem(hfd.Value,hfd.Value);
// //rb.SelectedItem.Selected = lt;
//}
}
