我有ASP.NET應用程序與ListView。我從Active Directory獲取數據,現在如果ListVew正在構建,現在我需要一個等待符號。我以爲我使用來自Ajax Control工具包的一個UpdateProgress控件。但是我不知道如果我點擊一個按鈕,並且等待符號(例如gif)關閉,如果ListView完成,我該如何使用它。 :(如何使用UpdateProgress控件顯示等待時間

我的CS文件:

protected void btnBenutzerSuchen_Click(object sender, EventArgs e) 
{ 
    //If I click on this Button the gif must start 

    try 
    { 
     ... // my ListView get data 

     this.myListView.DataSource = dv; 
     this.myListView.DataBind(); 

     ... 

    } 
    catch (Exception) 
    { 
     ... 
    } 

    //If the ListView is finish the gif must close 
} 

我怎樣才能做到這一點,我能做到這一點與UpdateProgress如何:

<asp:UpdateProgress ID="UpdateProgress1" DynamicLayout="true" runat="server" AssociatedUpdatePanelID="?" > 
    <ProgressTemplate> 
    <div class="progress"> 
     <img src="images/ajax-loader-arrows.gif" />&nbsp;please wait... 
    </div> 
    </ProgressTemplate> 
</asp:UpdateProgress>

第一將你的listview aspx代碼放在更新面板

012中
<asp:UpdatePanel ID="up" runat="server"> 
    <ContentTemplate> 
     // Place your list View Code here 
     <asp:ListView .......... 
     ...... </asp:ListView> 
    </ContentTemplate> 
    <Triggers> 
     // If button is present outside update panel then specify AsynPostBackTrigger 
     <asp:AsyncPostBackTrigger ControlID="btnControlID" EventName="Click" /> 
    </Triggers> 
</asp:UpdatePanel> 

// Now Set AssociatedUpdatePanelID="up" in the UpdateProgress 

<asp:UpdateProgress ID="UpdateProgress1" DynamicLayout="true" runat="server" AssociatedUpdatePanelID="up" > 
<ProgressTemplate> 
<div class="progress"> 
    <img src="images/ajax-loader-arrows.gif" />&nbsp;please wait... 
</div> 
</ProgressTemplate> 
</asp:UpdateProgress>

必須在UpdatePanel中的按鈕?...媽媽在這裏是我的更新 – Tarasov

如果按鈕是內部更新面板然後指定一個回發觸發它,如果按鈕是更新外面板然後指定一個asynpostback觸發器,我會更新我的答案。 –

@塔拉索夫它的工作與否? –

嘗試將包含的代碼可能需要很長的時間來執行,那麼UpdateProgress控件到UpdatePanel的關聯一個UpdatePanel內的按鈕。你可能需要的代碼就像:

<asp:UpdatePanel ID="updatePanelMain" runat="server"> 
<ContentTemplate> 
    <asp:button runat="server" ID="btnBenutzerSuchen" OnClick="btnBenutzerSuchen_Click"/> 
</ContentTemplate> 
</asp:UpdatePanel> 

<asp:UpdateProgress ID="UpdateProgress1" runat="server" AssociatedUpdatePanelID="updatePanelMain" DisplayAfter="200"> 
<ProgressTemplate> 
    <div class="progress"> 
     <img src="images/ajax-loader-arrows.gif" />&nbsp;please wait... 
    </div> 
</ProgressTemplate> 
</asp:UpdateProgress> 

希望這會有所幫助。 :)

我做了一個小例子模擬一個按鈕點擊更新面板。注意必須設置的屬性AssociatedUpdatePanelID,以便顯示你的進度模板

的Default.aspx

<asp:ScriptManager ID="ScriptManager1" runat="server"> 
</asp:ScriptManager> 
<asp:UpdatePanel ID="UpdatePanel1" runat="server"> 
<ContentTemplate> 
    <asp:Button ID="btnDoSomething" runat="server" Text="Do Something" 
     onclick="btnDoSomething_Click" /> 
    <asp:ListView> YOUR_LISTVIEW_GOES_HERE </asp:ListView> 
</ContentTemplate> 
</asp:UpdatePanel> 

<asp:UpdateProgress ID="UpdateProgress1" DynamicLayout="true" runat="server" 
        AssociatedUpdatePanelID="UpdatePanel1"> 
    <ProgressTemplate> 
     <div class="progress"> 
      <img src="images/ajax-loader-arrows.gif" />&nbsp;please wait... 
     </div> 
    </ProgressTemplate> 
</asp:UpdateProgress> 

default.aspx.cs

protected void btnDoSomething_Click(object sender, EventArgs e) 
{ 
    System.Threading.Thread.Sleep(5000); 
    // or update listView 
}

它顯示的圖像,但列表視圖不建立比:/ – Tarasov

只需在updatePanel中添加listView和它將 –

顯示進度條在Asp.net
