I'm trying to migrate our apps to latest version, Q1 2013. Having few issues, the blocking one is an InvalidOperationException.

Description of one of the issues and steps it takes to reproduce:
 - WPF 4.0 app
 - RadTabControl as main canvas
 - RadGridView on one of the tabs, but not first
To reproduce just switch between tabs: when coming to the tab with RadGridView for the second time the IOE is thrown.

Exception details:

System.InvalidOperationException was unhandled by user code

Hi

I am using telerik watermarktextbox for a WPF application, I set windows 8 theme when application starts up, now I wanted to have the water mark text box to have my templated text with Segeo Font , italic and text color to be white. Both the text to be entered and the watermark content should be using Segoe WP Light , font size 10 and styled to be italic and text foreground color to be italic.

Unfortunately the water mark text does not apply this setting, however when i type some text they are according to the setting which i specified as Segoe WP Light , font size 10 ,  style to be italic.

Strange behavior is that if i change the textblock foreground to yellow for example then it works, why doesn't it work for white.

Please note that my background is black.

Let me know if its a bug or i am doing something incorrect.

<telerik:RadWatermarkTextBox FontFamily="Segoe WP Light" FontSize="12" Foreground="White" FontStyle="Italic" CaretBrush="White" Background="Transparent" Height="20" BorderThickness="0" WatermarkBehavior="HideOnClick" Margin="3,0,3,0" Grid.Column="1" x:Name="radRichTextBox" VerticalAlignment="Center">

<telerik:RadWatermarkTextBox.WatermarkTemplate>

<DataTemplate>

<TextBlock VerticalAlignment="Center" HorizontalAlignment="Left" FontFamily="Segoe WP Light" FontSize="12" Foreground="White" FontStyle="Italic" Text="Enter custom status"></TextBlock>

</DataTemplate>

</telerik:RadWatermarkTextBox.WatermarkTemplate>

</telerik:RadWatermarkTextBox>

Hi,
we use RadGridView to display a collection of objects.
the model of this collection is as follows:
Public Class Model
{
public Prop1;
public  Prop2;
..
private Dictionary<string, MethodInfo> extensionMethodeByfqdnNameCache = new Dictionary<string, MethodInfo>();
public object this[string name]
        {
            get
            {
                if (extensionMethodeByfqdnNameCache.Keys.Where(key => key == name).FirstOrDefault() == null)
                {

                    string folderPath = Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location);
 
                    string assemblyFilePath = name.Split(',')[1].Trim();
             
                    string[] assembliesSearchRslt = Directory.GetFiles(folderPath, assemblyFilePath   ".dll", SearchOption.AllDirectories);

       
                    if (assembliesSearchRslt.Count() < 1) throw new Exception("Cannot load assembly");

      
                    Assembly assembly = Assembly.LoadFrom(assembliesSearchRslt[0]);


                    var currentType = this.GetType();
         
                    var methodeinfo = currentType.GetMethod("GetExtensionObject");
                 
                    var extensionType = assembly.GetType(name.Split(',')[0].Trim());

                    MethodInfo generic = methodeinfo.MakeGenericMethod(extensionType);
                    extensionMethodeByfqdnNameCache.Add(name, generic);
                }

                return extensionMethodeByfqdnNameCache.Where(dic => dic.Key== name).FirstOrDefault().Value.Invoke(this, null);
            }
        }
}

The model is shared across multiple assembly.
using a modular mechanism personalized.
the grid is always displayed and each change (module) are added Propertie anotre specific model:
and recovering these properties through the binding as follows:
Model. [^ ClassName, Assembly]. Property

Note: Model contain a method "GetExtension" ClassName to load a Dicationnary.

Binding the work properly.

we create a personalized component filrage and we could fill it with the values ​​of this column grid personalized.

but when we must create a filter and passes FilterDescriptor Member of the filter [ClassName, Assembly]. Property with the operator Equal
unfortunately this does not filter the grid.

FilterDescriptor.Member is on, does that make a filter on the Model property declared in the Model class and can not invoke the method this [string name] to retrieve the extended properties?

how to do the filtering mechanism with an extension properties on the Model?

if you must use IColumnFilterDescriptor found in Q1 2012?

For Telerik WPF controls 2012.3.1129.45 I am getting an unwanted tab button (see attached screenshot) using the  XAML below.

Any suggestions on how to make this unwanted tab disappear?

Thank you,
Alan

I was curious if it is possible to add support for touch panning/scrolling to the RadGridView. All of our applications are for touch screens, and touch panning/scrolling would make the RadGridView much easier to use.

Thank you for the help.

Hi
Currently I display ColorEditor in a RadExpander in a RadPropertyGrid. When the expander is expanded the whole RadPropertyGrid expands to accommodate it.
Is it possible to present the ColorEditor initially collapsed so user can click to expand and spill outside of container as you can with the ColorPicker?
Or is there another container control I can use to emulate this?
Thanks
Craig

Hi Expertise,

I am using the RadcolorPicker in my project. when i click the color picker, i can able to see the color palatte. Totally 25 colors only available in this control... Can i have more color to access in this control? it means, Is there any options for "More color" in this pallette.?

Thanks in advance.

Hello,
I have a problem binding the SelectedItem of a child grid to a property on my view model. I've included the relevant XAML at the bottom.

The data binding of the SelectedItem of the parent Group finds the view model property okay. I've tried to use the same approach for SelectedItem of the child grid but a get a binding error 'BindingExpression path error: 'SelectedGroupItem' property not found on 'object' ''Group' '. Group is the type of the child object so I can understand why it complains.


How do I change the SelectedItem="{Binding SelectedGroupItem}" data binding expression to refer to the view model as the parent grid has done?

Hi everyone,

I am wondering if there is a way to know if the user close a window using the "X" button. I assume it's in the previewclosed event but what should i check in that event?

thank you

Hi,
i am using a readonly GridView with a column like this:

The problem is that the tooltip does not be displayed on column cells or on the column header.

Where did i make the mistake?
