局部刷新gridview的问题
html页：
HTML code
<body>
<form id="form1" runat="server">
<div>
</div>
<cc1:ScriptManager ID="ScriptManager1" EnablePartialRendering="true" runat="server">
</cc1:ScriptManager>
<asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
<cc1:UpdatePanel ID="UpdatePanel1" runat="server" >
<ContentTemplate>
<asp:GridView ID="GridView1" runat="server" Height="205px" Width="554px" AutoGenerateColumns="False" DataKeyNames="id" OnRowEditing="GridView1_RowEditing" >
<Columns>

<%-- <cc2:TimerControl ID="TimerControl1" runat="server" Interval="1000" OnTick="Timer1_Tick">
</cc2:TimerControl>--%>
</ContentTemplate>
</cc1:UpdatePanel>

</components>
</page>
</script>
</body>
后台.cs
C# code
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
showdb();
}
}
private void showdb()
{
SqlConnection con = new SqlConnection(System.Configuration.ConfigurationManager.AppSettings["strcon"]);
SqlDataAdapter da = new SqlDataAdapter("select * from admin", con);
DataSet ds = new DataSet();
da.Fill(ds,"users");
this.GridView1.DataSource = ds.Tables["users"];
this.GridView1.DataBind();
}
protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e)
{
this.GridView1.EditIndex = e.NewEditIndex;
showdb();
}
为什么没有实现自动刷新来更新gv里的数据呢？？？
------解决方案--------------------OnTick="Timer1_Tick"
这个事件代码呢？
------解决方案--------------------看看你后台的Timer1_Tick 这个函数!
使用vs2005将一个dataview绊定数据源,删除出错,提示必须声明变量？解决思路
