Ajaxify RadGrid和来自后台代码的标签
Ajaxify RadGrid和来自后台代码的标签
提问于 2012-04-19 03:33:31
我正在尝试在代码后面Ajax化RadGrid控件和标签。这是我的代码。但是当RadGrid改变时，标签值不会被刷新。你能告诉我这里可能出了什么问题吗？
谢谢你的帮助。

try
{
if (!Page.IsPostBack)
{
RadAjaxManager1.AjaxSettings.AddAjaxSetting(RadGrid1, lblName, null);
}

请检查下面的代码片段或演示。这对我来说是正确的。如果有任何问题，请告诉我。
.aspx
<telerik:RadScriptManager ID="RadScriptManager1" runat="server">
</telerik:RadScriptManager>
<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
</telerik:RadAjaxManager>
<telerik:RadGrid ID="RadGrid1" runat="server" OnNeedDataSource="RadGrid1_NeedDataSource"
AllowPaging="True" OnPreRender="RadGrid1_PreRender" AutoGenerateColumns="false">
<PagerStyle AlwaysVisible="true" />
<MasterTableView>
<Columns>
<telerik:GridBoundColumn DataField="Name" HeaderText="Name" UniqueName="Name">
</telerik:GridBoundColumn>
</Columns>
</MasterTableView>
</telerik:RadGrid>
<br />
<asp:Label ID="Label1" runat="server"></asp:Label>.aspx.cs
protected void RadGrid1_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
{
DateTime dt = new DateTime();
dynamic data = new[] {
new { ID = 1, Name ="Name1", customdate=dt,NO = 11.00},
new { ID = 2, Name = "Name2", customdate=dt,NO = 11.00},
new { ID = 3, Name = "Name3", customdate=dt,NO = 11.00},
new { ID = 4, Name = "Name4", customdate=dt.AddYears(2011),NO = 11.44},
new { ID = 5, Name = "Name5", customdate=dt,NO = 10.4}
};
RadGrid1.DataSource = data;
}
protected void Page_Load(object sender, EventArgs e)
{
RadAjaxManager1.AjaxSettings.AddAjaxSetting(RadGrid1, Label1, null);
}
protected void RadGrid1_PreRender(object sender, EventArgs e)
{
Label1.Text = DateTime.Now.ToString();
}在上面的例子中，如果你改变了radgrid的页面大小，那么它也会更新标签文本。

尝试不使用加载面板的重载：
RadAjaxManager1.AjaxSettings.AddAjaxSetting(RadGrid1, lblName);如果这仍然不起作用，请尝试如下所示：
ScriptManager.GetCurrent(Page).RegisterAsyncPostBackControl(RadGrid1);
ScriptManager.GetCurrent(Page).RegisterAsyncPostBackControl(lblName);页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
