gridview控件自动排寻后，按某一条件查询时报错：数据源不支持派寻
页面源码
GridView的 AllowPaging="True" AllowSorting="True"
<asp:BoundField DataField="name" HeaderText="楼宇名称" SortExpression="name" />
<asp:BoundField DataField="manager" HeaderText="管理员" SortExpression="manager" />
<asp:BoundField DataField="tel" HeaderText="联系电话" SortExpression="tel" />
<asp:BoundField Visible="False" DataField="bid" HeaderText="bid" InsertVisible="False"
ReadOnly="True" SortExpression="bid" />
在程序运行时若点击某一列的标题后能排序，但是排序后再按某一条件查询时就会出错，查询代码：
string strcn = ConfigurationManager.ConnectionStrings["mycon"].ToString();
SqlConnection cn = new SqlConnection(strcn);
cn.Open();
string strsql = "select bid,name,manager,tel from building";
if (txtcxgly.Text != "")
{
strsql = strsql+" where manager='" + txtcxgly.Text+"'";
}
if (ddllm.SelectedIndex != 0)
{
strsql = strsql+" where bid="+ddllm.SelectedValue;
}
if (ddllm.SelectedIndex != 0 && txtcxgly.Text != "")
{
strsql = strsql+" where manager='" + txtcxgly.Text+ "' and bid=" + ddllm.SelectedValue;
}
SqlDataAdapter adp = new SqlDataAdapter(strsql, cn);
DataSet ds = new DataSet();
adp.Fill(ds, "query");
GridView1.DataSourceID = null;
GridView1.DataSource = ds.Tables[0].DefaultView;
GridView1.DataBind();这句出错，提示数据源不支持排序
cn.Close();
[解决办法]
GridView1.DataSource = ds.Tables[0].DefaultView;
改成GridView1.DataSource = ds；
