RadAjaxManager and ajaxified controls don't get along

Hi, my name is Pablo Rodriguez and I've been having issues with ajaxified controls using load on demand and RadAjaxManager. I had to make most of my ajax requests by means of javascript callings to ajaxmanager.ajaxrequest() because after updating a load-on-demand combobox in the grid or a server-side- callback node in the treeview, when I perform any ajaxified postback managed by ajaxmanager, it would throw a javascript error and break the state of the page.

My current scenario is: nested RadSplitters with RadPanes, a treeview on the left, a RadGrid on the right that holds related load-on-demand comboboxes in each row, a collapsible RadPane on the bottom and some buttons below that. You can see it on the screenshot:

Link to the picture

For example, if I work with the comboboxes and then click on any of the buttons on the bottom or any of the arrows on the vertical splitter and then try to expand a node in the tree or request items in any of the combos, I’ll be presented the loading message and nothing else will happen, no matter how many times I click on the tree node or the combobox.

The usual workflow is to select files in the tree and drop them to the grid (file queue) and then fill the comboboxes, select the files (fill the metadata of each file) and send them to the server using the “send” button.

I’m not using any ajax panel, all ajax requests are managed by RadAjaxManager or by the controls themselves. I’m using RadControls for ASP.NET AJAX 2008_1_415_dev

What would be the best combination of controls in this scenario? I don’t want to lose performance and I would like to have a stable page state anytime I make ajax requests to the server.

Accessibility: Screen Resolution

Being >30 years old, I like to set my screen resolution to 1024x768. At this resolution, the RadGrid Smart Tag fills the vertical space, making the last item, "Edit Templates", inaccessible except by tabbing into the blindspot and pressing Enter. Is there a better way to manage this problem? I'm afraid that a higher resolution might ruin these old eyes.

Window onClientClose, Master & Page

Hello.

I have a masterpage with a RadAjaxManager where I have among other things a virtual scrolling grid like this: http://demos.telerik.com/aspnet-ajax/grid/examples/client/virtualscrollpaging/defaultcs.aspx

Works perfectly.

Then I have a content page with a WindowManager. The user can open two windows and add some data. When the windows close, I want to use an ajaxRequest to update the grid. I had this working perfectly before, but once I added the AjaxManager to the masterPage I had to remove it from the content page.

So I am now trying to contact the master page ajaxManager from the content page on windowClose:

    
                function ClientClose() { 
        
                    $find("<%= RadAjaxManager.GetCurrent(Page).ClientID %>").ajaxRequest("ClientCloseLeagues"); 
        
                }

    
            Protected Sub RadAjaxManager1_AjaxRequest(ByVal sender As Object, ByVal e As AjaxRequestEventArgs) Handles RadAjaxManager1.AjaxRequest 
        
                RadAjaxManager1.Alert("AjaxRequest raised from the " + e.Argument) ' works for "LoadMoreRecords" but not "ClientCloseLeagues" 
        
                If e.Argument = "LoadMoreRecords" Then 
        
                    RadGrid2.PageSize = 15 + RadGrid2.PageSize 
        
                    RadGrid2.Rebind() 
        
                ElseIf e.Argument = "ClientCloseLeagues" Then 
        
                    Dim RadGrid1 As RadGrid = Me.Page.FindControl("RadGrid1") 
        
                    RadGrid1.DataSource = Nothing 
        
                    RadGrid1.Rebind() 
        
                End If 
        
            End Sub

What actually happens when the ClientClose function gets executed is that RadGrid2 (in the master page) is refreshed, while I am desperately trying to refresh RadGrid1 in the content page.

I've been reading the documentation: http://www.telerik.com/help/aspnet-ajax/ajxajaxmasterpage.html
(The link to the code snippet doesn't work: http://www.Telerik.com/asp-net-community/forums/forum-thread.aspx?b311D=ebgbb)

I'm really unsure what steps I need to take to get this working. The worst thing is I have a deadline today, so pretty please with sugar on top, somebody help me :)

Regards,
-DJ-

How Remove Spacing Between Graphic Buttons?

In my radtoolbar I have graphics being pulled in for clicked, disabled, hovered, and image urls. I don't know if it's because of Q1 2009 install or what, but now I'm getting spacing between my graphic buttons in the toolbar.

I have tried playing with the skin, and setting the skin="". I have also played with plugging in cssclass with different values for padding, margins, and such but I can't resolve it.

I have no widths defined for the graphics, or the toolbaritems, or the toolbar itself.

What am I missing?

Thx

Hierarchy with Templates example

Hi
I would like to modify the hierarchy with templates demo for the radgrid but I am having a few problems understandinging it.

Here's the link

Firstly in the NestedViewTemplate there is this label inside the one of the pageviews of the multipageview control
<asp:Label ID="Label1" Font-Bold="true" Font-Italic="true" Text='<%# Eval("EmployeeID") %>'
Visible="false" runat="server" />

I don't understand what is going on here: Text='<%# Eval("EmployeeID")

Is the data from the current row in the master table also being bound to the NestedViewTemplate? I suppose it must be otherwise this label wouldn't have the correct value. Can you explain to me how/why the data is being bound to the NestedViewTemplate.

I have a second question. In the demo there is a grid inside the nested view template which is bound declaratively using an SQL data source. I would like to have a grid inside the template but i want to bind it programmatically and i don't know how. Is this possible and where do i do it? I presume in some data binding event for the nestedviewtemplate I have to find the grid from the controls collection of the nestedviewtemplate. But i don't know - I'm guessing. Any help would be much appreciated.

Many thanks
andrea
