[英]Showing a ModalPopupExtender control when an UpdateProgress control is activated
[英]Specify when UpdateProgress Control are displayed
是否有人擁有資源或提供了代碼示例,說明單擊某個按鈕時何時不顯示UpdatePrgress控件。
在您的標記中:
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<fieldset>
<legend>UpdatePanel</legend>
<asp:Label ID="Label1" runat="server" Text="Initial page rendered."></asp:Label><br />
<asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click" />
</fieldset>
</ContentTemplate>
</asp:UpdatePanel>
<asp:UpdateProgress ID="UpdateProgress1" runat="server">
<ProgressTemplate>
Processing...
</ProgressTemplate>
</asp:UpdateProgress>
在后面的代碼中:
protected void Button1_Click(object sender, EventArgs e)
{
// Introducing delay for demonstration.
System.Threading.Thread.Sleep(3000);
Label1.Text = "Page refreshed at " +
DateTime.Now.ToString();
}
這應該工作,嘗試一下...
