Mono support

Hi,
as I recently read in Miguel de Icaza's blog the Telerik ASP.NET AJAX Controls now support the Mono framework (see: http://tirania.org/blog/archive/2009/Apr-03.html).
I tried to reach the test page mono.telerik.com but unfortunately I was not able to reach it.
Is it possible to reach it under another url or something?

Best regards,
Ferdinand

Scheduler doesn't work after postback

Hi all

I have a scheduler in a user control which works fine but when I popup a window and load it into the page the scheduler won't work.

Well...it will work in that it shows the scheduler and I can navigate. But after the first navigate the scheduler no longer fires any postbacks. Does anyone know what this could be?

Cheers
Jon

Updating a panel from a button outside a panel , cause controls inside panel to update the panel

Hello,

I've created a panel ("Panel1") with a textbox ("TextBox1") inside it.
Outside "Panel1" I have a button ("Button1")

I also have a "Panel2" with a label ("Label2") inside it

When the text in TextBox1 changes, I want to update "Label2"/ "Panel2", WITHOUTupdating "Panel1"
When "Button1" is clicked, I want to update "Panel1"

This does not seem to work.
When I update "Textbox1", "Panel1" is updated as well. I don't want that. I just want to update "Panel2"

If I remove ajax on "Button1", it works as expected.
"Panel2" is updated, and "Panel1" does not update.

Is this a bug ?

Expanding all NestedViewTemplates when grouped client-side

Hi,

I have a Rad Grid with a NestedViewTemplate that can be expanded/collapsed client-side. One of the requirements for this grid is to also be able to expand/collapse all NestedViewTemplates in the Grid client-side with the event raised by an external control, which I can do easily with this code that I found here in an earlier thread:

    
            function expandCollapseAll(expand) { 
        
                            var grid = $find("<%=rgDomestic.ClientID %>"); 
        
                            var table = grid.get_masterTableView(); 
        
                            var rows = table.get_dataItems(); 
        
                            for (var i = 0; i < rows.length; i++) { 
        
                                var Row = rows[i]; 
        
                                if (expand == true) { 
        
                                    Row.set_expanded(true); 
        
                                } 
        
                                else { 
        
                                    Row.set_expanded(false); 
        
                                } 
        
                            } 
        
                        }

The problem is that I also have a requirement that the grid needs to have grouping-by-column ability (also done on the client-side). However, when the grid is grouped by a column or columns, the code above no longer works and gives me the following error message when it hits the line below, 'title' is null or not an object:

    
            if(_348.title==this._owner._hierarchySettings.ExpandTooltip)

Is there any way I can expand or collapse all nestedviewtemplates with an external control client-side when the Rad Grid has been grouped by a column? Thank you.

Skinsfolder missing

Just installed ASP.Net AJAX and for some reason the referenced "Telerik" folder from "C:\Program Files\Telerik\RadControls for ASPNET AJAX Q1 2008\Skins" is missing.

Any idea why that might be the case?

Is there a way for me to just get a zip of that folder and put it in there manually?

Thanks
Karl

Calling events from a grid created at run time

Hi,

I am trying to call an event with the following code but get an error stating:

An object reference is required for the non-static field, method, or property 'FileExplorerHelper.gridFileView_RowDrop(object, Telerik.Web.UI.GridDragDropEventArgs)

    
            RadGrid gridFileView = new RadGrid(); 
        
                        gridFileView.ID = gridFileViewID; 
        
                        gridFileView.EnableEmbeddedSkins = false; 
        
                        gridFileView.Skin = "FileExplorer"; 
        
                        gridFileView.AllowPaging = true; 
        
                        gridFileView.PageSize = 20; 
        
                        gridFileView.AllowSorting = true; 
        
                        gridFileView.ClientSettings.AllowRowsDragDrop = true; 
        
                        gridFileView.ClientSettings.Selecting.AllowRowSelect = true; 
        
                        gridFileView.RowDrop += new GridDragDropEventHandler(gridFileView_RowDrop); 
        
                        pnlFileView.Controls.Add(gridFileView);

    
            protected void gridFileView_RowDrop(object sender, GridDragDropEventArgs e) 
        
                { 
        
                }

What am I doing wrong please?

Thanks,

Multiple clientside updates/inserts at once

Hi,

I'm trying to create a clientside function to insert a break-appointment in an existing appointment.
The scheduer is updated via AJAX.

for example
1 Appointment from 10:00 to 14:00
1. |10:00 ------------------------------------------------------------------------------- 20:00|
^oldAppointment^
after inserting the break there should be 3 appointments like this:

1.|10:00 ------------- 15:00| 2.|15:00 ------------- 16:00| 3.|16:00 ------------- 20:00|
^oldAppointment^ ^breakAppoinment^ ^afterbreakAppointment^
I hope i explained it comprehensible.
What I am doing so far is this:
When click on the existing big appointment this is fired (pseudo code / real code is syntactically correct, but too complex to post ):

    
            oldAppoinment.set_end(15:00); 
        
            var breakAppointment = new Telerik.Web.UI.SchedulerAppointment(); 
        
            breakAppointment.set_start(15:00); 
        
            breakAppointment.set_end(DateAdd(16:00); 

            var afterbreakAppointment = new Telerik.Web.UI.SchedulerAppointment();

                        breakAppointment.set_start(16:00); 
                    
                        breakAppointment.set_end(DateAdd(20:00); 

                        scheduler.insertAppointment(afterbreakAppointment);

                        scheduler.updateAppointment(oldAppoinment);

                        scheduler.insertAppointment(breakAppointment);

When this event is fired is see 3 async-postack sent to the server, but only the last one (scheduler.insertAppointment(breakAppointment)) gets an answered, the other two(scheduler.updateAppointment(oldAppoinment);scheduler.insertAppointment(afterbreakAppointment);) remain waiting for an answer until timeout.

Is there a way to send these 3 commands in a single postback?
Or can I even setup the scheduler so the client can manipulate appointments as he likes an postback the whole scheduler-viewstate; like a "save changes"-button.

The RADTreeView has this functionality (trackChanges/commitChanges)

Any idea how I could resolve this problem.
I'd appreciate any help!

thanks in advance,
Lukas
