How can I best refresh a listview on a timely basis (automatically). I had a look at issue Q262250 which is a great help, but I keep getting the following error:
"Besturingselement RefreshTransportRequestsTimer van het type ASPxTimer moet binnen een form-label worden geplaatst met runat=server.".
What am I missing?
Thanks on beforehand.
We have closed this ticket because another page addresses its subject:

Hi Ad,
Thank you for posting your code snippet. It looks like you need to add the ASPxTimer control to the Page.Form.Controls collection, to resolve this problem:
C#void Frame_TemplateChanged(object sender, EventArgs e)
{
if (Frame.Template == null)
return;
Page p = (Page)Frame.Template;
if (p.FindControl("RefreshTransportRequestsTimer") != null)
return;
DevExpress.Web.ASPxTimer.ASPxTimer timer = new DevExpress.Web.ASPxTimer.ASPxTimer();
timer.ID = "RefreshTransportRequestsTimer";
timer.Tick += new EventHandler(timer_Tick);
timer.Interval = 10000;
timer.Enabled = true;
p.Form.Controls.Add(timer);
}
Please update your code accordingly, and let me know whether this helps.
Thanks,
Alex

@Kirsten: While we do not have a ready WinForms example for this particular scenario, I elaborated more on how to implement this at T164532.
