Force RAD AJAX Panel to update

[Jacques Woolston]

Hi,

Is there a way to force the RAD AJAX Update Panel to update in the same way you can with the MS Update Panel, for some reason the RAD one is not updating controls within when another MS Update Panel modifies the content within the RAD panel.

Thanks

hi


Can you please paste your complete C#/VB.NET ASPX and Javascript code here, so I can take a look at it.
And please elaborate and give me the steps needed to reproduce the problem.

Best...

I'll create a complete sample project with examples and open a support itcket if that's easier, it's quite a lot of code!

I have now submitted a support ticket with an example regarding this thread.

I'm currently using the following to trigger a postback in ajax panel to refresh the panel:

function refreshData()
{
   var pnl = <%= RadAjaxPanel1.ClientID %>;
   pnl.AjaxReqeustWithTarget('<%= RadAjaxPanel1.UniqueID %>','');
}

It seems to be working, but the loadingpanel isn't displaying?  What am I doing wrong?  Is there a better method?

Hello Johnson,

You can directly invoke the AjaxRequest() method of the AjaxPanel in order to trigger the update, AjaxRequestWithTarget() is only being used when you need some other control to fire up its default event. Currently there is a known problem with LoadingPanel in MasterPage scenarios. If this is the case make sure the LoadingPanel is in the same namingcontainer and set the LoadingPanelID from code behind.

Kind regards,

How to do that from code behind?

the idea is that i have an AjaxPanel inside a usercontrol, and i update a textbox inside that panel from the containing form, but the text is not updating unless something is HARD refreshing the panel.

is there a way to force reload from code behind?

Unfortunately Sebastian, this is more a javascript solution (client side), i cannot use it since the two AjaxPanels exists in two different contexts and linking between them would be very difficult.

isnt there a common library of module between all AjaxPanels? i imagines that there is somethings like:

BigBrother.Execute(String.Format("$find('{0}').ajaxRequest();", RadAjaxPanel2.ClientID));

Hello Alaa,

In such case you may consider ajaxifying the entire scenario with single RadAjaxManager and specify appropriate ajax settings/invoke its ajaxRequest method when needed. Examine the implementation from the following online example for further details:
