ASP.NET GridView动态绑定怎么排序

[wa6190064]

如题，最好给点代码哈

[dingjian2008]

<asp:GridView ID="GVCell" runat="server" Width="100%" AllowSorting="True" onsorting="GVCell_Sorting" DataKeyNames="网元">
</asp:GridView>

protected void GVCell_Sorting(object sender, GridViewSortEventArgs e)
{
DataTable dt = GetData();//获取数据源
DataView dv = new DataView(dt);
if (ViewState["gvsort"].ToString() == " DESC")
{
ViewState["gvsort"] = " ASC";

dv.Sort = "排序列名 asc";
}
else
{
ViewState["gvsort"] = " DESC";

dv.Sort = "排序列名 desc";
}
dt = dv.ToTable();
GridView1.DataSource = dt;
GridView1.DataBind();

}

在绑定结束时间里写代码设置 SortExpression 属性。

能不能不再重新绑定数据源啊

也可使用List<T>实现自定义排序

使用dataSet数据源，启用排序，每列添加一个属性，就可以排序了。

[parverxiao]

protected void GridView1_Sorting(object sender, GridViewSortEventArgs e)
{
//排序
GridView1.EditIndex = -1;
if (ViewState["sortColumn"] == null)
{

ViewState["sortColumn"] = e.SortExpression.ToString();
ViewState["sortDirection"] = "ASC";

}
else
{
if (ViewState["sortDirection"].ToString() == "ASC")
{
ViewState["sortDirection"] = "DESC";
}
else
{
ViewState["sortDirection"] = "ASC";
}

}
string sortExpression = e.SortExpression;
bind();
}

通过JS感觉比较灵活一些。老外一个sorttable.js以前用过，很简单，用了后你会有体会的。
