GridView分页后点击后面页面显示空白
本帖最后由 warden325 于 2010-11-01 21:03:50 编辑 我是初学者，请多指教。
如题，将GridView和数据库查询结果绑定起来后，点击查询出了结果。但是点击第二面或者其他的，就直接变空白了。
前台：
<asp:GridView ID="ResGridView" runat="server"
DataSourceID="SqlDataSource1" AllowPaging="True" BackColor="White"
BorderColor="#E7E7FF" BorderStyle="None" BorderWidth="1px" CellPadding="3"
GridLines="Horizontal" onpageindexchanged="ResGridView_PageIndexChanged">
<RowStyle BackColor="#E7E7FF" ForeColor="#4A3C8C" />
<FooterStyle BackColor="#B5C7DE" ForeColor="#4A3C8C" />
<PagerStyle BackColor="#E7E7FF" ForeColor="#4A3C8C" HorizontalAlign="Right" />
<SelectedRowStyle BackColor="#738A9C" Font-Bold="True" ForeColor="#F7F7F7" />
<HeaderStyle BackColor="#4A3C8C" Font-Bold="True" ForeColor="#F7F7F7" />
<AlternatingRowStyle BackColor="#F7F7F7" />
</asp:GridView>

{
ResGridView.DataBind();
}
}
protected void QryButton_Click(object sender, EventArgs e)
{
string strTable = "";
/*set strTable...*/
SqlDataSource1.SelectCommand += "select cus_id from t_temp" + strTable;
ResGridView.Visible = true;
ResGridView.DataBind();
}
protected void ResGridView_PageIndexChanged(object sender, EventArgs e)
{
ResGridView.DataBind();
}
}
protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
GridView1.PageIndex = e.NewPageIndex;
bind();//绑定数据
}
