gridview取值，在线等

Question

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow || e.Row.RowType == DataControlRowType.Header || e.Row.RowType == DataControlRowType.EmptyDataRow )
        {
            
             foreach (GridViewRow row in this.GridView1.Rows)
            {
                HyperLink link = (HyperLink)row.Cells[4].Controls[0];
                string Member_order_ID = link.Text.Trim();
                if (e.Row.Cells[5].Text == "重复消费")
                {
                    HyperLink hyl = (HyperLink)e.Row.FindControl("EditID");
                    hyl.NavigateUrl = "OrderAgain.aspx?Member_Order_ID=" + Member_order_ID;
                }
                else
                {
                    HyperLink hyl = (HyperLink)e.Row.FindControl("EditID");
                    hyl.NavigateUrl = "RegisterQiChuMember.aspx?Member_Order_ID=" + Member_order_ID;
                }
           }
        } 
    }------------------------------------------------为什么我这里Member_order_ID取到的值都是上一行的，而且第一行是没有值得

Answer 1

if (e.Row.RowType == DataControlRowType.DataRow )

Answer 2

改为:
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow || e.Row.RowType == DataControlRowType.Header || e.Row.RowType == DataControlRowType.EmptyDataRow )
        {
            
                             HyperLink link = (HyperLink)row.Cells[4].Controls[0];
                string Member_order_ID = link.Text.Trim();
                if (e.Row.Cells[5].Text == "重复消费")
                {
                    HyperLink hyl = (HyperLink)e.Row.FindControl("EditID");
                    hyl.NavigateUrl = "OrderAgain.aspx?Member_Order_ID=" + Member_order_ID;
                }
                else
                {
                    HyperLink hyl = (HyperLink)e.Row.FindControl("EditID");
                    hyl.NavigateUrl = "RegisterQiChuMember.aspx?Member_Order_ID=" + Member_order_ID;
                }
           
        } 
    }

Answer 3

GridView1的RowDataBound事件，每一行绑定时都会触发一次，它本身就是一个“遍历”，在里面再加上foreach循环，当然就不对了

Answer 4

Eddie兄：
    HyperLink link = (HyperLink)row.Cells[4].Controls[0];
这句好像就不对了吧，你把我的foreach去除了，那么row就不存在了，那这里我该用什么替代

Answer 5

e.Row.RowType == DataControlRowType.Header
去掉

Answer 6

e.Row.RowType == DataControlRowType.Header
去掉
------------------------------
还是不行的，每一页都是第一行没有值，后一行的值都是前一行的

Answer 7

    HyperLink link = (HyperLink)e.Row.Cells[4].Controls[0];

Answer 8

 HyperLink link = (HyperLink)e.Row.Cells[4].Controls[0];----这行报错“Specified argument was out of the range of valid values.
Parameter name: index “

Answer 9

if (e.Row.RowType == DataControlRowType.DataRow )
{ 
HyperLink link = (HyperLink) GridView1.Rows[e.Row.RowIndex].FindControl("EditID");
}
最好把DataKeyNames="ID"设个关键字作为索引．
PagerSettings-Visible=false;
