Exclude a control from using a RadAjaxLoadingPanel?

I have a default loading panel set because I want pretty much everything to use it except for one thing. Is there a way to exclude something? Here's a condensed version of what I'm hoping to make work:

<telerik:RadAjaxManager runat="server" DefaultLoadingPanelID="loadingPanel">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="btnLoad">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="rgResults"/>

<telerik:AjaxUpdatedControl ControlID="lblResults"/>

</UpdatedControls>

</telerik:AjaxSetting>

<telerik:AjaxSetting AjaxControlID="txtIDs">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="rtb1"/>

<telerik:AjaxUpdatedControl ControlID="rtb2"/>

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

I know I can just leave out a default loading panel and explicitly set a loading panel for the ones I want, like so:

<telerik:AjaxUpdatedControl ControlID="rgResults" LoadingPanelID="loadingPanel"/>

<telerik:AjaxUpdatedControl ControlID="lblResults"/>

But if all but one are going to use the loading panel, it's less wordy to do it the other way.

Ajaxified control still does postback when updated the first time

Hi,

I have this scenario:
Two controls (say controlA and controlB), both contain some RadButtons. If a click occurs in controlA, it should update controlB and vice versa. But only case 1 works, case 2 doesn't work correctly.

This is my code:

protected override void OnPreRender(EventArgs e)

{

base.OnPreRender(e);

RadAjaxManager manager = RadAjaxManager.GetCurrent(Page);

manager.AjaxSettings.AddAjaxSetting(controlA, controlB, loadingPanel);

manager.AjaxSettings.AddAjaxSetting(controlB, controlA, loadingPanel);

}

The second case only works after one click, e.g. the second, third, ... click works correctly and the loading panel will be displayed.
Both controls don't have any conditional controls, all buttons are added in CreateChildControl. EnsureChildControls is called in OnLoad of both controls.

Which of the controls might be erroneous in this case? The control which does the trigger or the control which is updated?

Issue with UpdatedControls

Hi there,

In a section of our page, we have three radGrids, each of which control the visibility of a asp:button (for example if rows.count > 0). Now that we are rolling out AJAXified grids across our application, we have reached this page and noticed that there are a number of issues introduced once we apply AJAX on these grids.

We have a function that is called in pageLoad and ItemCreated (for the affected grids) which determines the visibility of the above button. However we have noticed that once the grid is AJAXified, and the button is added as an UpdatedControl of the grid, the visibility of the button is not affected by this function, even if we removed all items in the grid.

However, if I were to reload the page after removing all items in the grid, the button would be hidden as the above visibility function would return a False, but ideally we would like this to be done during the AJAX request of the grid.

Is there something that we are missing here??

Hope you can help

Regards

A.

<telerik:AjaxSetting AjaxControlID="radFScore">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="radFScore" LoadingPanelID="RadAjaxLoadingPanel1" />

</UpdatedControls>

</telerik:AjaxSetting>

<telerik:AjaxSetting AjaxControlID="radFScore">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="btnPreview"/>

</UpdatedControls>

</telerik:AjaxSetting>

Persist files in Session instead of temp folder

I wonder how easy to persist the uploaded files in ASP.NET Session instead of writing them into the temporary folder?

Btw, is it allowed to prevent writing files into the temp folder?

Server side event when creating new node via context menu

I have a treeview and a context menu based on the examples on this website, with some added functionality.

When right clicking on a node and adding a new node, the node is put into edit mode. If I change the name of the newly created node (I set a default value in code behind), the NodeEdit server side event fires, which is what I want.

However, if I do not change the name, the server side event does not fire. This is likely by design. However, in the case where I am creating new nodes, I need that server event to fire anyway.

Is there a way to do this?

Recurring events not displayed properly

I have a strange problem with recurring events.

I have a recurring event scheduled once a week with no end date.

When I start my application I open the RadScheduler in week view, and the recurring event is shown as it should. But if I go to the next week the event is not shown.

If I then switch to month view the recurring event is shown, but only the one in the week I was in before I switch to month view.
Then, if I switch back to week view, the event is shown for that week, even if it wasn't before.

In my application I also have a RadCalendar, where the dates with appointments are bold. To do this, in the AppointmentDataBound event of the RadScheduler I use the e.Appointment.RecurrenceRule to add the dates to the SpecialDays collection of the RadCalendar. This works fine, so I don't think there is anything wrong with the recurring event itself, just the way it is displayed in the RadScheduler.

The same behavior also happens if I have recurring event scheduled once a day, and also if I vary the number of occurrences, end dates etc

Any ideas?

Regards, Jill-Connie Lorentsen
