RadTextBox modified?
Is there some property of a radtextbox that can be retrieved in the codebehind that indicates whether the value has been modified?  for a password field, I need to know if it has been modified, and if it has not been modified, not modify the password store on the back end.

Can';t get RADScheduler to work with WCF
I'm trying to get a RADScheduler project switched over from using calls directly to a SQL Server database, to working with a WCF service. I took the example provided and modified it to work in our situation. But, I'm getting a webexception:

The remote server returned an error: (415) Cannot process the message because the content type 'application/json; charset=utf-8' was not the expected type 'text/xml; charset=utf-8'.. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

RadGrid Contextual Menu on Mac (FF and Safari)
Hello,

I've implemented the RadGrid contextual menu on a RadGrid and it works fine on PC. When I right click on MAC, the menu appears for a brief time but the page postbacks before I can select an Item.

Here is code I've implemented.

Thanks in advance for your help.

RadGrid Pager Bug
There is a bug in the RadGrid Pager when the page size is set to Integer.MaxValue (I added an "All" options to the page sizes). Instead of displaying "Page 1 of 1" it displays "Page 1 of 0". Some of the GridPagerItem.Paging values are also incorrect. Here is what they contain in the ItemCreated and ItemDataBound events:

Count = 21474483647
CurrentPageIndex = 0
DatasourceCount = 240
FirstIndexInPage = 0
IsFirstPage = True
IsLastPage = False
LastIndexInPage = 239
PageCount = 0
PageSize = 21474483647

This is the code I use to modify the page sizes dropdown list:
Public Sub SetPageSizes(oPagerItem As GridPagerItem, aSizes As String())
    Dim rcbPager As RadComboBox = DirectCast(oPagerItem.FindControl("PageSizeComboBox"), RadComboBox)
    Dim iTotalItems As Integer = oPagerItem.Paging.DataSourceCount
    rcbPager.Items.Clear()
    For Each sSize As String In aSizes
        Dim iSize As Integer = 0
        If sSize.ToUpper() = "ALL" Then
            iSize = Integer.MaxValue
        Else
            If Not Integer.TryParse(sSize, iSize) Then
                Continue For
            ElseIf iTotalItems < iSize Then
                Continue For
            End If
        End If
        Dim oNewItem As New RadComboBoxItem(sSize, iSize.ToString())
        oNewItem.Attributes.Add("ownerTableViewId", oPagerItem.OwnerTableView.ClientID)
        rcbPager.Items.Add(oNewItem)
    Next
    If iTotalItems > 0 Then
        Dim oItem As RadComboBoxItem = rcbPager.FindItemByValue(oPagerItem.OwnerTableView.PageSize.ToString())
        If oItem IsNot Nothing Then
            oItem.Selected = True
        End If
    End If
End Sub

There is another strange thing to in that, if I add the "All" item as the last item to the PageSizeComboBox as above, upon postback the .Text of the item is no longer "All", but the same as the .Value.

There's other strange behavior with the PageSizeComboBox items on postback as well. If I add an item to the end that contains a fairly small value, it gets sorted first instead of last, and the default items that I did not add back (like "20" and "50") still show up in the items list.

RadWindow Blank in IE9
Hi,

I'm using a RadWindow in IE9 but when launched the contents of the window appear blank/empty, works fine in Chrome, Firefox etc.

In IE9 the console gives the following error...

SCRIPT5007: Unable to get value of the property 'getElementsByTagName': object is null or undefined 

We are using the following version of the telerik controls: 2012.2.607.40

Any ideas on why it is failing?

Thanks

[Solved] Calling RadWindow from ContextMenu
Hi,
I use the ContextMenu in RadTreeView for add/edit/delete nodes. On inserting and editing nodes, I need some user input, in order to do some other work. Therefore I want to open a RadWindow on clicking a contextmenuitem with value of selected node as parameter.

Could you please suggest me how to handle this scenario.

Thanks in advance,
