We have a particular scenario where we have a MasterPage that contains a RadWindow in the RadWindowManager.  When this RadWindow is made visible, certain actions that are made in the RadWindow need to be reflected in the current content page loaded in the MasterPage asyncronously. We are attempting to accomplish this task through various javascript calls.

The goal of our RadWindow is to act as a 'DockCatalog' that contains a listing of the available docks the user can add to the page, and a listing of the current docks already on the page.  Through this window, entries in the database are added/removed that represent the docks for the user.  The content page loaded into the master page contains all of the loaded current docks for the user.

The following javascript is called from the page in the RadWindow.  It's purpose is to call another javascript function to refresh the docks on the content page when the user selects to add or remove a dock item from the page.
// Refresh the docks on the parent page of the radwindows to show the changes  
// the user made from the catalog. 
function RefreshParentPage() 
    var rWindow = GetRadWindow(); 
    if (rWindow != null
        rWindow.BrowserWindow.RefreshDocks(); 


The RefreshDocks() function exists on the master page and calls the actual AjaxRequest which will cause Docks to be added or removed from the current page.
// Refresh the docks on the page because the user has  
// added/removed dock customizations from the catalog window. 
function RefreshDocks() 
    var ajaxManager = <%= RadAjaxManagerMaster.ClientID %>; 
    ajaxManager.AjaxRequest("CatalogItemsInUseChanged");  


The handler for this ajax request will reload the docks on the page based on entries in the database for the user.  That way the RadWindow catalog can add and remove items to this content page.

Our problem is that we are not sure what AjaxSettings to add to the AjaxManager so that we can see the added/removed Docks without refreshing the page.  I know the initiator needs to be the RadAjaxManager, but I am unsure what should be the updated control.  Since the AjaxRequest could add or remove docks to and from the current layout, what control should I place as the updated control.   I only want it to be ajaxify the process of adding and removing docks from the dock layout. 

Below is a snippet of the markup file for the content page that has the docks.
<telerik:RadDockLayout runat="server" ID="RadDockLayout1" OnSaveDockLayout="RadDockLayout1_SaveDockLayout" 
        OnLoadDockLayout="RadDockLayout1_LoadDockLayout"
        <telerik:RadSplitter ID="RadSplitter1" runat="server" Width="100%" Height="550px"
            <telerik:RadPane ID="RadPane1" runat="server" Scrolling="Y"
                <telerik:RadDockZone runat="server" ID="RadDockZone1" BorderStyle="None"
                </telerik:RadDockZone> 
            </telerik:RadPane> 
            <telerik:RadSplitBar ID="RadSplitBar1" runat="server" Width="20" Height="100%"></telerik:RadSplitBar> 
            <telerik:RadPane ID="RadPane2" runat="server" Scrolling="Y"
                <telerik:RadDockZone BorderStyle="None" ID="RadDockZone2" runat="server"
                </telerik:RadDockZone> 
            </telerik:RadPane> 
        </telerik:RadSplitter> 
        <div style="display: none"
            <asp:UpdatePanel runat="server" ID="UpdatePanel1"
                <Triggers> 
                </Triggers> 
            </asp:UpdatePanel> 
        </div> 
    </telerik:RadDockLayout> 


Any suggestions?  Is there a better way I can add docks from on the fly actions occuring within the RadWindow?

Hello Adam,

You should add the RadDockZone where the RadDock object is going to be added as updated control. If you do not know which one in runtime, then try adding them programmatically to the AjaxSettings based on some conditions or flags you set.

Steve, Thanks for the reply.  I am glad someone would be able to decipher what I was trying to explain!

On the Page Load event handler, I added two ajax settings with the ajaxManager as the initiator and both of my two zones as updated controls.  When I do this, it appears to work and the docks are either added or removed.

But then when I perform any command action on the dock (move, collapse, etc...) the command is performed as expected, but the docks commands then become disabled.  They are still visible on the dock, but they can not be clicked.  The docks can't even be moved afterwards.

When I remove the ajax settings I added for the zones, the commands work fine, but then I have the problem I originally posted.  It is like ajaxifying the zone breaks the ability of my async dock commands.

For a reference, I have an UpdatePanel creating triggers on the events for the docks similar one of your examples. here is the code.
AsyncPostBackTrigger saveStateTrigger = new AsyncPostBackTrigger(); 
saveStateTrigger.ControlID = dock.ID; 
saveStateTrigger.EventName = "DockPositionChanged"
UpdatePanel1.Triggers.Add(saveStateTrigger); 
 
saveStateTrigger = new AsyncPostBackTrigger(); 
saveStateTrigger.ControlID = dock.ID; 
saveStateTrigger.EventName = "Command"
UpdatePanel1.Triggers.Add(saveStateTrigger); 

The updatePanel is controlling my async dock commands.  So somehow I think the UpdatePanel and the ajax settings for the zones are not playing together nicely.

Thanks,
Adam

Hello Adam,

I've missed the part from your first post, that you are using both UpdatePanel and Prometheus ajax in your app. Indeed using two different ajax controls is not a good idea and you should either use only the AjaxManager or the UpdatePanel. This is due to the fact that once a control fires a request, it will be intercepted by the closest parent control (in this case the UpdatePanel) and the AjaxManager would not have any effect on that control. Similar scenario is observed with AjaxManager and AjaxPanel (more info here).
Take a look at this online example to see how ajaxification of dock objects is handled through MS AJAX. You can inspect the code by using the tabs below the example.

Kind regards,

Steve,  Thanks for the advice.

We have taken the approach to leverage your Prometheus Ajax controls over the MSAjax controls.  With that said, I am trying to migrate your portal example to not use UpdatePanels.

We are having some difficulty ajaxifying the commands (and 'DockPositionChanged' event) for the docks.
We would like to do something like this...

AjaxSetting ajaxSetting = new AjaxSetting(dock.ClientID);
ajaxSetting.EventName = "Command";
this.RadAjaxManager1.AjaxSettings.Add(ajaxSetting);

in hopes that it would replace...

AsyncPostBackTrigger saveStateTrigger = new AsyncPostBackTrigger();
saveStateTrigger.ControlID = dock.ID;
saveStateTrigger.EventName = "Command";
UpdatePanel1.Triggers.Add(saveStateTrigger);

Any suggestions??

You should change the following in "MyPortal example":

1) Change the UpdatePanel on the page with aps Panel, e.g.
<asp:Panel ID="PanelForUpdate" runat="server"></asp:Panel>
2) Add an RadAJAXManager on the page
3) Instead triggers you should use AjaxSettings in CreateSaveStateTrigger method. For example:

AjaxSetting
setting1 = new AjaxSetting(dock.ID);
setting1.EventName =
"DockPositionChanged";
setting1.UpdatedControls.Add(
new AjaxUpdatedControl(PanelForUpdate.ClientID, ""));
RadAjaxManager1.AjaxSettings.Add(setting1);

4)Also you should change the ButtonAddDock_Click handler. E.g. you should use $find('RadAajaxManager1').ajaxRequest('');
instead of:
$find('{0}').doPostBack('DockPositionChanged');

I think that's all.

Hi,

 

I have using myprotal sample and use the last code suggestion of using  asp panel and ajaxmanger. However, I tried to add module using ajaxrequest  and add the module to updatepanel and zone1. However, radock‚Äôs zone assignment is not missing from the view state.  I have used ajaxrequest because the radwinow close event will trigger the AjaxRequestButton function. Html and c# is provided.

 

 

Thank you,

 

Purvang

Hello Joerg,

I prepared a sample project for you (attached to this post) illustrating how to create RadDocks dynamically with RadAjax. Check it out and let me know if I missed something from your logic.

I hope this helps.

Thank you for the sample code for the portal. However, the controls will be added via ajaxrequest and not on ButtonClick bubbled event. I have a radwindow that loads the controls and when event is fired from radwindow client side code ajaxrequrest is fired .  However, I am getting some load state errors when it tried adding user conrols with radgrid and clientside rowclick feature. I have included some c# code and aspx page.
