FormTemplate OnUpdateCommand fails after update to 2010Q3

Hello, I have a RadGrid inside a RadPageView. The RadGrid is using a formtemplate for editing. Before the update to 2010 Q3 (December) the OnUpdateCommands were working perfectly. After the update clicking on the templates update button closes the edit form but the OnUpdateCommand handler is never called.

There are other RadGrids with FormTempaltes in our application that are contained inside a RadPanel item that were working correctly after the update. RadPageView -> RadPanelItem -> RadGrid

I was able to rollback to the previous version of the Telerik dlls and the application worked properly again. I have confirmed this issue on two separate machines.

Is anyone else seeing this issue?

Thanks,
Chris

Bar Chart Series Border

I'm having a little issue I can't seem to figure out. I have a bar chart with 2 series that I am adding programmatically. I’m using the vista skin and when the chart renders the first series bar has a black border but the second series doesn’t.

I can’t find how to turn the border off for the first series. Any suggestions would be appreciated.

Erase Items of RadComboBox on demand

Hi, I have 2 combox box on Load on demand.
The first one is in Autopostback mode cause when an item is selected, the second combo box is loaded on demand thanks to the selected value of the first combobx. It works perfectlly.

Nevertheless, when an another item is selected in the first combobox, I want to "erase" the selected item of the second combobox.

I tried to use item.selected.remove(), but the selected item persists in search field. Is there a trouble with the removing option when a combobox is loaded on demand? I also tried to count the number of the second combo box but it returns 0.

Thanks a lot for helping.

RAD Editor bind to dynamic page, and allow properties to change

We have an ASP.Net application that displays information for each page from the database.
The information includes standard ASP.Net controls and custom controls.
It means all these controls definition, properties (i.e position, color fiont etc) is stored in the database.

We want to develop a wizard that allows to open such a dynamic page and change the properties of these dynamic controls and save changes as properties back into database.

Can we open a page in RAD Editor that has different elements(controls) defined from database, click of each element (control)
access and change each controls properties (like font-color, background, etc) and when clicked save should save each property into the database.

My manager is expecting Telerik RAD Editor should help to achieve this.

Any guidance on this side is appreciated.

regards
Ami

Telerik.Web.UI.RadScheduler is null or not an object

First off, I'm a newb to the Telerik ASP.NET controls and am currently eval'ing the latest download. I've been through all of the forums and can't find an answer to this one.

I'm getting a "Microsoft JScript runtime error: Telerik.Web.UI.RadScheduler is null or not an object' error. I'm basing my code from what I found out on the "Scheduler / Binding to Generic List" demo. I'm using Master pages and am trying to simply bind the RadScheduler to a custom appointment class which I have created. I'm wanting to have read-only calendar representation of a single day's activities on a webform. Pretty basic requirement for now <grin>... My code below:

Markup:

<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">

<telerik:RadScheduler ID="RadScheduler1" runat="server" EnableEmbeddedSkins="false"

Skin="MPower" ReadOnly="true" DataKeyField="AppointmentID" DataSubjectField="Subject"

DataStartField="Start" DataEndField="End" DataRecurrenceField="RecurrenceRule"

DataRecurrenceParentKeyField="RecurrenceParentID" width="750px"

DayStartTime="08:00:00" DayEndTime="20:00:00" TimeZoneOffset="03:00:00" >

</telerik:RadScheduler>

</asp:Content>

CodeBehind (located in the Page_Load):

AppointmentCollection appointments = new AppointmentCollection();

this.RadScheduler1.DataSource = appointments.GetAppointmentsByDate("08/19/2011");

As well, if it proves helpful...the offending JS line of code is below. I can shift-F9 and see that my scheduler control "ctl00_ContentPlaceholder1_RadScheduler1" is populated w/all of the correct data from my binding code...it's just that the "Telerik.Web.UI.RadScheduler" is null

Telerik.Web.UI.RadScheduler._preInitialize("ctl00_ContentPlaceHolder1_RadScheduler1",0,0,1,false);

Thanks in advance for any advice!
Jim

RadEditor? Need some input please

Hello -

I have a situation where I need to display RTF text, but not allow the user to modify it in any way. The RadEditor control would be perfect for this, but I can't seem to find a way to remove the toolstrips (I found how to remove the buttons but not the toolstrips), as well as disable edit ability.

Is the Editor control what I would want to use in this situation, or is there perhaps another tool which just displays RTF?

Thanks much,
Matt

Incorrect file length - how to solve this ?

Hello,

I wonder if somebody knows how to get real file size (length) of the uploaded file. In my application I use this method:

protected void fileUploaded(object sender, FileUploadedEventArgs e)
        {
            try
            {
                if (RadAsyncUpload1.UploadedFiles.Count > 0)
                {
                    if (targetPersonalTmpFolder.Exists.Equals(false)) targetPersonalTmpFolder.Create();

                    foreach (UploadedFile uploadedFile in RadAsyncUpload1.UploadedFiles)
                    {
                        //UploadedFileInfo uploadedFileInfo = new UploadedFileInfo(uploadedFile);

                        string fullPath = Path.Combine(targetPersonalTmpFolder.ToString(), uploadedFile.GetName());
                        uploadedFile.SaveAs(fullPath, true);

                        TmpFiles_List.Add(new UplodedFileData()
                        {
                            FileName = uploadedFile.GetName(),
                            FullFileName = targetPersonalTmpFolder.ToString() + @"\" + uploadedFile.GetName(),
                            //FileContentLength = Math.Round(uploadedFile.InputStream.Length / 1024d, 0).ToString() + " KB"
                            FileContentLength = Math.Round(uploadedFile.ContentLength / 1024d, 0).ToString() + " KB"
                        });

                    }

                    BindFiles();
                    BindTmpFiles();
                }
            }
            catch (Exception ex)
            {
                //Pravdepodobne bol stlaceny klaves F5 refresh stranky...
                ReinitializeForm();
            }
        }

--------------------------------------------------------------------------------------------
The problem is that property uploadedFile.ContentLength doesn't return real length of the file. I've found that this uploadedFile.InputStream.Length returns correct file size, but when I tried to use it, then this error appeared: The process cannot access the file because it is being used by another process...

Something similar is described here: http://www.telerik.com/community/forums/aspnet-ajax/async-upload/temporary-files-locked-after-upload.aspx

For further information you can check the attachment.

Please help me to solve this issue...
