System.IndexOutOfRangeException:找不到列 [英] System.IndexOutOfRangeException: Cannot find column

问题描述

我正在实现gridview排序，这是用户控件的一部分.下面的代码给我Indexoutofrange错误.

I am implementing gridview sorting which is part of a user control. Below code gives me Indexoutofrange error.

错误消息位于

dtView.Sort = strSort;

错误消息:

System.IndexOutOfRangeException:找不到列TEXT_COUNTY_ID.

System.IndexOutOfRangeException: Cannot find column TEXT_COUNTY_ID.

有人能指出我在做什么错吗?

Can anyone point out what I am doing wrong?

protected void SortGridData_Hkl(Object sender, GridViewSortEventArgs e)
    {
        GridView _dgd_work_onoff = (GridView)Page.FindControl("bodyuc$dgd_work_onoff");
        DataSet dstemp;
        DataView dtView;
        if (ViewState["dsfetchResults"] != null)
        {
            dstemp = (DataSet)ViewState["dsfetchResults"];
            string strSortOrder = ViewState["SortOrder"].ToString();

            if (strSortOrder == "DESC")
            {
                strSortOrder = "ASC";
                ViewState["SortOrder"] = strSortOrder;
            }
            else
            {
                strSortOrder = "DESC";
                ViewState["SortOrder"] = strSortOrder;
            }

            string strSort = e.SortExpression.ToString() + " " + strSortOrder;
            ViewState["SortString"] = strSort;

            dtView = dstemp.Tables[0].DefaultView;

            dtView.Sort = strSort;
            if (dtView.Count != 0)
            {
                if (_dgd_work_onoff != null)
                {
                    _dgd_work_onoff.DataSource = dtView;
                    _dgd_work_onoff.DataBind();
                }
            }


        }

'dsfetchResults'应该包含数据库中的数据.

'dsfetchResults' is suppose to contain the data from the database.

推荐答案

找到解决方案.列名称与数据库列的名称不同.

Got the solution. The column name was different from that of the database column.
