I have been running into various issues using SL5 RTM and the Q3 SP1 Silverlight controls. I am curious if you plan to release Silverlight 5 sources as well?

My issues:

1. {System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.} This is a breaking bug because it crashes the silverlight client.

I cannot tell if this is an issue with telerik controls, sl5 rtm, or a combination. When I switched to SL5 RTM I have this issue with both the SL4 binaries and the SL5 binaries. I did not encounter this problem using SL5 beta w the SL4 binaries.

Other people have had a similar issue:
http://stackoverflow.com/questions/8495242/silverlight-5-accessviolationexception/8512923#8512923
http://forums.silverlight.net/t/245076.aspx/1?Error+in+project+when+upgrage+from+SL4+to+SL5

In our project it is thrown after a SelectedValue binding changes. The error is thrown on line 3047 "this.EditableTextBox.Text = text" in the UpdateEditableTextBox() method of RadComboBox.cs

I am working on reproducing this in a sample project.

2. Handling the CellDoubleClickEvent on RadGridView does not work with the SL5 binaries, but it does w SL4 binaries. See the sample code https://docs.google.com/open?id=0Bx6l5GmEYzJJYmJiYWRmYjQtMzliYy00NWU1LTk1YjYtZDg4ZTQ5M2RmMTk4

Hi,

Straight onto your problems:

1) I am afraid that I also was unable to reproduce this problem with a simple application, I guess there are other factors that lead to this exception. I would need more detail about your application:
- the RadComboBox declaration - a code snippet would be best, if you could send the related code-behind it would be also of great help (event handlers, configuration, etc.)
- the theme used - whether it is a standard Telerik theme or a custom
- environment - please check again if you are using our SL5 assemblies (the best way is to open the XAP file and check the file versions)
- the controls around - whether the combobox is put in another control - ChildWindow, RadWindow, Docking, etc.
- steps to reproduce - does the exception occur when the control is shown for the first time, do you have to click or type inside it in order to throw the exception, etc., whatever could be of help.

2) You can check this demo for more info about CellDoubleClick. Everything is working normally so far.

Hi,

I got the same issue with "{System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.}"

One way to cause this error is to set celledittemplate on a radgridview column that contains a editable radcombobox and also a button that shows a childwindow. Upon closing the childwindow the selecteditem/value is updated with a new value which usually causes this exception.

I think this is caused by the fact the childwindow is opened the cell goes back into normal state and when the childwindow is closed
the binding is updated and exception is thrown on the propertychanged event.

I've submitted a support ticket including an example, the support ticket ID is: 495383

Yes, I was able to reproduce the problem. It looks like a bug in Silverlight, but unfortunately I haven't been able to reproduce it only with standard Silverlight controls. I will continue my research and eventually we will report the problem to Microsoft.

I found two workarounds for the problem:
1) Edit in the EditableTemplate template and set Foreground on the PickerTextBox control.
2) Create a new control deriving from RadComboBox and put the following code inside:
public class FixedComboBox : RadComboBox
{
    public override void OnApplyTemplate()
    {
        base.OnApplyTemplate();
        var editableTextBox = (TextBox)this.GetTemplateChild("PART_EditableTextBox");
        if (editableTextBox != null)
        {
            editableTextBox.Foreground = this.Foreground;
        }
    }
}

Unfortunately both will break the automatic inheritance of the Foreground property, but at least will not throw exceptions.

I will write again if I find something better.

I am also getting this issue with RadComboBox using Silverlight 5. I am having the same issue as one of the people on stackoverflow from the OP's links:

"I'm seeing this exception when databinding to a hidden element. We have some fields that are visible or not based on some databinding, but both of those fields are updated with another databinding. When the RaisePropertyChanged is fired on the hidden field we get the AccessViolationException. I had to add some checks to my code to suppress the RaisePropertyChanged when the control isn't visible. "

I have a 2 RadComboBoxes binding to the same SelectedItem, and one of them is hidden. This is in a form, and if the user toggles a button, the one that was visibile is now hidden and the hidden one becomes visible. When I click the now visible drop down, I get:

{System.AccessViolationException: Attempted to read or write protected memory.
This is often an indication that other memory is corrupt.}

Thanks,
Bryce

Hello All,

The best workaround we have found so far is to replace the PickerTextBox control from the RadComboBox control template with a regular TextBox and this is implemented in internal build version 2011.3.1316 (January 16th). If you have a custom control template for RadComboBox I strongly recommend replacing the PickerTextBox with a TextBox and updating the visual states.

Please, find attached a project that was used to test the exception and let me know if the problem persists on your side. If it does, please send me a project that can be used to observe it and we will do our best to provide a fix as soon as possible. The exception can be observed in both Silverlight 4 and 5 applications.

RadDateTimePicker and RadNumericUpDown suffer from the same problem and will be updated with the internal build next week.

@Anthony: Yes, Microsoft is aware of this problem and we are waiting for a final conclusion. I believe there is a bug in the Silverlight runtime, the attached solution has a test with plain Silverlight controls that is also able to reproduce the exception.

Hi,

The fix should be there. We made some tests with the project Valeri send below for both RadComboBox and RadNumericUpDown and with the latest version of the controls (2012.1.215.1050) no error was observed. The fix that changed the element to Textbox instead of PickerTextbox is there (you can see with a tool like silverlight spy).

The problem might be that this fix does not handle all scenarios. Could you please send me a project that the problem can be seen with the latest binaries.

All the best,

I am also having the problem with the RadNumericUpDown control. I'm still on 2011 Q3 SP1, but it doesn't sound like that matters. It also happens whether I targert Silverlight 4 or 5...simply having Silverlight 5 dev installed seems to break it.

In my case I kind of know the circumstances that cause it....

I have a tree control on the left with different types of elements:
Parent Item
Child Item
Parent Item
Child Item

When you select a Parent, the right side controls fill with Parent properties, when you select a child, it fills with child properties.
The Parent and child are completely different objects so the right side has 2 sets of controls in Borders. When you click on a parent we show the parent border and hide the child border and when you click on a child we show the child border and hide the parent border...one set of controls visible at a time.

The app starts with a Parent item selected, so the Child border is hidden
If I then select a Child with a non-zero value being pushed into the UpDown, it crashes.
If the child has all *zero* values, it does not crash...maybe because the default value is zero and does not trigger a change?

As an experiment I set it so that the child border is *never* hidden and it does not crash in either the non-zero or zero case. It has some connection to the visibility state of the control when you set it.

So, my work-around which is still holding up is to force an update of the Child border before its controls are filled with values:

ChildBorder.Visibility = Visibility.Visible

ParentBorder.Visibility = Visibility.Collapsed

' THIS FIXES IT FOR ME

ChildBorder.UpdateLayout()

' Fill Child controls.

' ...

With the explicit UpdateLayout after making the border visible, I no longer have the exception, which lets me continue working.

I have recently upgraded to Silverlight 5 developer runtime. Still running Silverlight 4 version of Telerik's controls though. I'm getting this error from time to time in the Set-method of RadDateTimePicker.DateTimeText:

[StyleTypedProperty(Property = "CalendarStyle", StyleTargetType = typeof(RadCalendar))]
[StyleTypedProperty(Property = "ClockStyle", StyleTargetType = typeof(RadClock))]
public partial class RadDateTimePicker : Control, IThemable
{
    // ...
 
    public string DateTimeText
    {
        get { return (string)GetValue(DateTimeTextProperty); }
        set { SetValue(DateTimeTextProperty, value); } // <- Crash here
    }
}

answered on 02 Mar 2012, 09:37 PM

I've upgraded to 2012 Q1 and the crash I was getting with the RadNumericUpDown appears to be fixed...but setting some other properties throws a "System.NullReferenceException: Object reference not set to an instance of an object".

I don't know how to attach the sample app since only images appear to be allowed so here is the XAML and the code:

MainPage.xaml:

<UserControl x:Class="SilverlightApplication2.MainPage"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

<Grid x:Name="LayoutRoot" Background="White">

<telerik:RadNumericUpDown HorizontalAlignment="Left" Name="RadNumericUpDown1" VerticalAlignment="Top" />

</Grid>

</UserControl>

MainPage.vb: set property on UpDown on page load. This throws exception every time for me.

Partial Public Class MainPage

Inherits UserControl

Public Sub New()

InitializeComponent()

End Sub

Private Sub MainPage_Loaded(sender As Object, e As System.Windows.RoutedEventArgs) Handles Me.Loaded

RadNumericUpDown1.NumberFormatInfo.NumberGroupSeparator = ""

End Sub

End Class

Hi,

@John

Few releases back we changed the behavior of RadNumericUpDown and now you have to create a new instance of NumberFormatInfo as RadNumericUpDown doesn't have a default one. You have to change your code to:

RadNumericUpDown1.NumberFormatInfo = New NumberFormatInfo() With {

.NumberGroupSeparator = ""}

@Patrik

Are you using the latest 2012.1.215 version of the controls? You can't attach a project to a forum thread, in order to attach a project you have to open a support thread or a Bug report.

I have installed latest official release of Telerik controls for Silverlight 4 (2012.1.326.140) and I'm getting AccessViolationException for RadNumericUpDown with SL5 RTM (with SL4 RTM works fine). It seams that problem is in the style. I created custom style where in ControlTemplate for VisualState "Disabled" I set Foreground of textbox:

<ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Foreground" Storyboard.TargetName="textbox">
   <DiscreteObjectKeyFrame KeyTime="0" Value="#FF8D8D8D"/>
</ObjectAnimationUsingKeyFrames>

If I comment this part AccessViolationException disappear.

RadNumericUpDown used in different pages inside DataForm. The problem exists for all of them. Like I mentioned it works fine with Sl4 RTM, and with Sl5 it works only if i disable part where I set Foreground of textbox for "Disabled" VisualState (this is only place where I actually change Foreground of textbox, I don't think it has anything to do with disabled state, it is something related with setting foreground of textbox).

Best regards,
Predrag

Hi Predrag,

I could not get the exception using your style. However, there are a few other exceptions related to missing resources.

Also, an important thing to note is that since 2012 Q1 RadNumericUpDown uses a regular TextBox control instead of PickerTextBox in its control template.

I suggest that you upgrade to 2012 Q1 or 2012 Q1 SP1 version of the controls, because the style you are using seems outdated. Let me know if you have any issues with the updated one.

I am attaching here a copy of the latest xaml for RadNumericUpDown for reference.
