Hi,

I'm trying to get the position of a context menu relative to his placement target by using MousePosition property and there is an issue.

Here's what I have :

<telerik:RadContextMenu>
    <telerik:RadMenuItem Header="Add item" Command="{Binging AddItemCommand}" CommandParameter="{Binding MousePosition, RelativeSource={RelativeSource FindAncestor, AncestorType=telerik:RadContextMenu}}"/>
</telerik:RadContextMenu/>

When I click on "Add Item", the position that I received in the viewModel is (Double.NaN, Double.Nan), so I conclued that the value of MousePosition is updated after the evaluation of the bindings. Is there another way to get the MousePosition of the contextMenu that would works with MVVM ?

Thank you,

Etienne

Hi,

I have a RadTreeView where data is populated from an xml using XmlDataProvider.  I would like to bind the SelectedItem of TreeView to a ViewModel property of type string. When I do the binding using SelectedItem={Binding mydata}", the value mydata is set to System.Xml.XmlElement type.

I was able to find the logic to get the exact value. For testing purpose, I created a new TextBox control to retreive the exact selected data.

 <TextBox  DataContext="{Binding ElementName=ReportersTreeView, Path=SelectedItem}" Grid.Row="6"   Text="{Binding XPath=@Name}"></TextBox>

However in real scenario, I don't need this TextBox. 

I want to know how can I integrate this code to my tree view control such that XPath=@Name is correctly retrieved from SelectedItem  and set to my viewmodel property?

Below is my TreeView control and my Template.

 <HierarchicalDataTemplate x:Key="NodeTemplate">
            <TextBlock x:Name="tb"/>
            <HierarchicalDataTemplate.ItemsSource>
                <Binding XPath="child::node()" />
            </HierarchicalDataTemplate.ItemsSource>
            <HierarchicalDataTemplate.Triggers>
                <!--<DataTrigger Binding="{Binding Path=NodeType}" Value="Text">
                    <Setter TargetName="tb" Property="Text" Value="{Binding XPath = @name}"></Setter>
                </DataTrigger>-->
                <DataTrigger Binding="{Binding Path=NodeType}" Value="Element">
                    <Setter TargetName="tb" Property="Text" Value="{Binding Path=Attributes[Name].Value}"></Setter>
                </DataTrigger>
            </HierarchicalDataTemplate.Triggers>
        </HierarchicalDataTemplate>
        <XmlDataProvider x:Key="ReportersDataProvider" Source="ProbesTree.xml"
                         XPath="*">

 <telerik:RadTreeView Grid.Row="2"  IsDragDropEnabled="True" Name="ReportersTreeView"  SelectionMode="Single" IsSingleExpandPath="False" IsLineEnabled="True"   AutomationProperties.AutomationId ="ReportersTreeView" VerticalAlignment="Stretch"
                ItemTemplate= "{StaticResource NodeTemplate}" ItemsSource="{Binding Source={StaticResource ReportersDataProvider}}"  VerticalContentAlignment="Stretch" HorizontalContentAlignment="Stretch"/>

Please help.!!!!

Thanks,

I have an object that I have some data in. The object has the following properties

Description
Amount
Date

I want to plot a chart where Date would be in X axis and Amount will be on Y (which is easy). If I just set the ItemsSource and the X and Y properties, this works fine.

However for each distinct description I want to show a new series. But I want to keep this dynamic. so if there is Series 1 and Series 2 in Description, then only two would show, if there is more than 2 then all would show. How is this doable?

Hi

  I don't know what I am asking is can be done, but have to try a shot, Currently using Schedule view for my project, and on that as you people know there is Day,Week,Month and timeline option on it, what I am expecting is, can Onclick event can be done  on "Day" or "week" so that  it can trigger method in viewmodel(class file) currently this click option is nothing to do with Viewmodel, the reason I need this because, if employee has an many appointments Ex 1000, it takes time to load all the 1000 values,so what I need is on page load it should show only todays appointments, on selection of "Week" it should call a method and pass the week parameters to get only week's appointment and so on, I want to get appointment based on selection of Day or Month it has to load only based on that Selection event, not the entire future appointment list, hope I made it understand , Please let me know for any clarification, and I am attaching the pic of existing view of mine, so please guide me in this, any help is appreciated, thanks :)

Hi

We are trying to do custom sorting per grouping in a datagrid and I've been unable to find any examples. Say we have 2 groups, foo and bar, and we want to sort the row on 2 different properties. The groups are, in this particular example, known and I somehow like to specify a GroupSortingExpression per grouping. 

In the attached screenshot, I would like to sort the group 'group-1' by foo and the group 'group-2' by bar. Is this possible?

Any hints are greatly appreciated!

Hello,
In this demo: http://demos.telerik.com/silverlight/#ImageEditor/Cropping you use BitmapToRadBitmapImageConverter. Can you please share the code for the converter?

I suppose it is something like this:

public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
        {
            var image = value as BitmapImage;
            if(image != null)
                return new RadBitmap(image);

            return null;
        }

But will be good to have the original code.

I am using the the Windows7Theme for my application and I want to do so for RadToggleButtons too...but I need it to have a more pronounced background color when checked (like the Office Blue theme which highlights the control in yellow). What is the easiest way to accomplish this?

Thanks.

We have the "TileReorderMode" property set to "None" - but when using your finger to scroll left and right the tiles they still move up and down somewhat -- which messing with scrolling smoothly.  Is there a way to stop this individual tile movement?

When we have the tile's "InEnabled" set to "False" - this allows for the desired smooth scrolling - but still need a way to trigger actions when clicking / touching the tiles -- and can't get any events to fire when tiles are disabled...

Would love a solution for either of the two situations above...

Hello

I have some problems with drag and drop inside RadListBox. Everything is fine but it only works for first element in RadListBox - I mean that I can drag only first item down in any place, but only the first one. When I create a separate project everything works fine but it is not working in my application. I can't send any example of it and that a shame but I have a question. Is it possible that only first element can be dragged? 

What can be wrong, maybe some property needs to be set for other items when drag is being initialized? OnDragInitializeHandler is being fired but nothing after that. Many thanks for your advice.
