Question

gridview分页不显示数据

aspx.cs中如下：
public void getList(string sql) //将满足sql语句的数据绑定到GridView
{
DataTable dt = GetDataTable(sql);
GrvList.DataSource = dt;
GrvList.DataKeyNames = new string[] { "Id" };
GrvList.DataBind();
}
protected void GrvList_PageIndexChanging(object sender, GridViewPageEventArgs e) //实现GridView的分页
{
GrvList.PageIndex = e.NewPageIndex;
getList(sql);

}
protected void GrvList_SelectedIndexChanging(object sender, GridViewSelectEventArgs e)
{
string stuName = (string)Session["UserName"];
int stuId = Convert.ToInt32(Session["StuId"]);.....
aspx如下：
<asp:GridView ID="GrvList" runat="server" CssClass="table2" AllowPaging="True" AutoGenerateColumns="False" PageSize="6" OnPageIndexChanging="GrvList_PageIndexChanging"

OnSelectedIndexChanging="GrvList_SelectedIndexChanging" Visible="False"> <Columns>.....

Answer 1

getList(sql);
你分页的事件中，没有这个sql。
