Question

我已经尝试过从我读到的所有内容（从添加需求源到添加pageindexchanged等等），但仍然无法弄明白......任何帮助都会感激不尽......

以下是我的代码......

<asp:UpdatePanel runat="server" UpdateMode="Conditional">
    <ContentTemplate>
        <telerik:RadAjaxManager ID="ram1" runat="server">
        <AjaxSettings>
            <telerik:AjaxSetting AjaxControlID="ajaxtimer1">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="rgNewsFeed" LoadingPanelID="LoadingPanel1" />
                </UpdatedControls>
            </telerik:AjaxSetting>
        </AjaxSettings>
    </telerik:RadAjaxManager>

    <telerik:RadAjaxLoadingPanel ID="LoadingPanel1" runat="server" />

      <telerik:RadGrid ID="rg1" runat="server" ShowStatusBar="True" AllowPaging="true" >
         <MasterTableView AutoGenerateColumns="False" TableLayout="Fixed">
            <Columns>
                <telerik:GridBoundColumn DataField="CommentSubject" HeaderText="Subject" />
                <telerik:GridHyperLinkColumn DataTextField="CommentText" DataTextFormatString="{0}" DataNavigateUrlFormatString="~/Views/m.aspx?pEntityID={0}" 
                    DataNavigateUrlFields="CmtTextID" HeaderText="Details" UniqueName="gbcCommentText" />
                <telerik:GridBoundColumn DataField="EntityFundName" HeaderText="Entity/Fund" />
                <telerik:GridBoundColumn DataField="EnteredBy" HeaderText="Entered by" />
                <telerik:GridBoundColumn DataField="CommentAge" HeaderText="Last Updated" />
            </Columns>
         </MasterTableView>
    </telerik:RadGrid>

    <asp:Panel ID="Panel1" runat="server">
        <asp:Timer ID="Timer1" runat="server" Interval="3000">
        </asp:Timer>
    </asp:Panel>

    </ContentTemplate>
</asp:UpdatePanel>

背后的代码

Protected Sub OnLoad(sender As Object, e As System.EventArgs) Handles Me.Load

        rg1.DataSource = dt 'some datatable
        rg1.DataBind()

End Sub

Public Sub Timer1_Tick(ByVal sender As Object, ByVal e As EventArgs) Handles Timer1.Tick
        rg1.DataSource = dt 'some datatable
        System.Threading.Thread.Sleep(500)
End Sub

Protected Sub rgLeoNotesNewsFeed_NeedDataSource(sender As Object, e As Telerik.Web.UI.GridNeedDataSourceEventArgs) Handles rgLeoNotesNewsFeed.NeedDataSource


    rg1.DataSource = dt 'some datatable


End Sub

Answer 1

首先，我将asp:UpdatePanel替换为telerik:RadAjaxPanel。我不得不使用telerik组件一段时间，没有最好的时间。如果您正在使用radgrid并且要使用updatepanel，请使用相应的telerik组件，例如telerik:RadAjaxPanel。通过这种方式，您将遇到更少的问题。

其次，我对以下部分感到困惑

<telerik:AjaxSetting AjaxControlID="ajaxtimer1">
    <UpdatedControls>
        <telerik:AjaxUpdatedControl ControlID="rgNewsFeed" LoadingPanelID="LoadingPanel1" />
    </UpdatedControls>
</telerik:AjaxSetting>

您似乎没有ID为rgNewsFeed和ajaxtimer1的任何控件。你基本上是说 RadAjaxManager 来更新 ajaxtimer1 更新中的 rgNewsFeed 。

这不应该像

<telerik:AjaxSetting AjaxControlID="Timer1">
    <UpdatedControls>
        <telerik:AjaxUpdatedControl ControlID="rg1" LoadingPanelID="LoadingPanel1" />
    </UpdatedControls>
</telerik:AjaxSetting>

此外，您需要像这样来格式化您的网格

<telerik:AjaxSetting AjaxControlID="rg1">
    <UpdatedControls>
        <telerik:AjaxUpdatedControl ControlID="rg1"></telerik:AjaxUpdatedControl>
    </UpdatedControls>
</telerik:AjaxSetting>

不确定您的问题是否与这些相关，但请尝试一下，看看是否有效。

修改

Protected Sub OnLoad(sender As Object, e As System.EventArgs) Handles Me.Load rg1.DataSource = dt 'some datatable rg1.DataBind() End Sub

我认为你应该在每次调用时设置数据源，但只有在它不是回发时才调用DataBind方法。请尝试以下方法。

Protected Sub OnLoad(sender As Object, e As System.EventArgs) Handles Me.Load rg1.DataSource = dt 'some datatable If Not IsPostBack Then rg1.DataBind() End If End Sub
