Ajax UpdateProgress timeframe [Resolved]

Posted by Sharpcnet under C# on 3/11/2014 | Points: 10 | Views : 945 | Status : [Member] | Replies : 3
<asp:UpdateProgress runat="server" AssociatedUpdatePanelID="UpdatePanel1" >  
<ProgressTemplate>
<asp:Image ImageUrl="/images/progress.gif"/>
</ProgressTemplate>
</asp:UpdateProgress>

<asp:UpdatePanel ID="UpdatePanel1" runat="server">
//gridview, textbox and button controls
</asp:UpdatePanel>


When testing this page on a local machine, the database tasks complete in a second. Maybe that's the reason the progress image doesnt show up. So I tried this..

btnSave_Click()
{
System.Threading.Thread.Sleep(3000);
//Code to save record to DB , bring back some data and bind to grid
}


Now, after clicking on btnSave, the image appears for 3 seconds and the DB task is done.

Here is the Question. When hosted on a server, the tasks might take 5-10 sec. So, in this case, will the image stay until the task is done or will it just stay for 3 secs, irrespective of the status of task.

I actually want to show the image until the tasks are done.

You code is perfect. It will show image until the server or db task is done.
You can try to see your self. Just increase the System.Threading.Thread.Sleep(10000); to some more the it will show till the task finished.

See the below example:-

<body>
<form id="form1" runat="server">
<div>
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:UpdateProgress ID="UpdateProgress1" runat="server" AssociatedUpdatePanelID="UpdatePanel1">
<ProgressTemplate>
<asp:Image ImageUrl="/images/progress.gif" runat="server" />
</ProgressTemplate>
</asp:UpdateProgress>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:Button ID="btnSubmit" runat="server" Text="Submit"
onclick="btnSubmit_Click" />
</ContentTemplate>
</asp:UpdatePanel>
</div>
</form>
</body>



public partial class _Default : System.Web.UI.Page 
{
protected void Page_Load(object sender, EventArgs e)
{

}
protected void btnSubmit_Click(object sender, EventArgs e)
{
System.Threading.Thread.Sleep(5000);
}
}


Hope you understand.
