我有一个网格表,我在页面加载时进行数据绑定
if (!IsPostBack)
{
BindGridViewUsers(msgID);
}
网格视图位于更新面板内,我每隔3秒更新一次面板
<asp:UpdatePanel ID="holder" runat="server">
<Triggers>
<asp:AsyncPostBackTrigger ControlID="Timer1" EventName="Tick" />
</Triggers>
<ContentTemplate>
计时器滴答每隔3秒进行一次数据绑定
protected void Timer_Tick(object sender, EventArgs args)
{
String MsgID = HttpContext.Current.Request.QueryString["MsgID"];
int msgID = Convert.ToInt32(MsgID);
BindGridViewUsers(msgID);
}
我也在表中启用了排序,但排序只停留了3秒钟,然后完成数据绑定并恢复原始表格,即使更新到表格后,如何保留排序。
<asp:BoundField DataField="TimeRead" ItemStyle-Width="25%" HeaderText="TimeRead"
SortExpression="TimeRead" />
<asp:BoundField DataField="Name" ItemStyle-Width="45%" HeaderText="Name" SortExpression="Name" />
<asp:BoundField DataField="Email" ItemStyle-Width="45%" HeaderText="Email" SortExpression="Email">
排序:
private void SortGridView(string sortExpression, string direction)
{
String MsgID = HttpContext.Current.Request.QueryString["MsgID"];
DataTable dataTable = BindGridViewUsers(Convert.ToInt32(MsgID)).Tables[0];
if (dataTable != null)
{
DataView dataView = new DataView(dataTable);
dataView.Sort = sortExpression + direction;
Grid_UserTable.DataSource = dataView;
Grid_UserTable.DataBind();
}
}
答案 0 :(得分:0)
当你调用SortGridView()方法时,我们传递两个参数sortExpression和direction
只需在页面级别声明静态变量,并为其指定方向更改方法中的方向
if (direction.Equals("ASC"))
direction = "DESC";
else
direction = "ASC";
并对Dataview进行排序。
希望这有效!
