Hello,

I have a telerik tabcontrol which has 5 TabItems. When I press RightArrow key i can navigate to one tab to other.

This way i reach to the last tab. Now if again i press RightArrow key i need to move back to first tab from where I started.(Cyclic behavior).

This is not happening currently.

Is there some property of telerik tabcontrol which can be use for doing so or we need to find some workaround?

Thanks & Regards,

Abdi

Do you have an example that would show me how to drag and drop between a RadGridView and a RadDiagram?

Thanks for your help,

Joel

I've got RadGridView with couple of columns. Most of them are standard GridViewDataColumn (or combobox). Some of them uses CellEditTemplate to do some custom editing.

When I edit standard ones, validation errors are shown from edit control - as in attachment1.

When I edit custom ones, validation errors are shown normal at first, but when I try to leave control I get validation error from edit control and cel level - as in attachment2.

How can I make this custom columns behave like standard ones?

Good afternoon, Telerik Team!

I have a question, how would I add items in a outlook bar programmatically

Example:

I have a Rad Outlook Bar in a WPF grid without items, in another moment,  I need programmatically include I items 1,2,3  sequentially one by one

including headers too in it

Is this possible?

Hello!

Is it possible in the GridView to swap rows and columns?
I want to display my items (bound to ItemsSource) as different columns, while the rows are fixed (and correspond to the "Columns" of the GridView).

It should look similar to http://blogs.microsoft.co.il/tomershamam/2008/09/22/lthowtogtreplace-listview-columns-with-rowslthowtogt/

However, I would prefer if the style matches our other (telerik) grids.

Hello,

 I am evaluating your control suit for WPF and I find it extremely tedious and tiresome to colorize a control. I have to reimplement the control template just for a simple color change. Not only this is extremely counter-productive, it can lead to errors when the template is updated on a future UI for WPF version.

Let's take the simple case of a DropDownButton control. I want to have 2 dropdownbutton controls. I have settled on the theme, say Office2013 theme. I want the e.g. selected background on the first control to be red and on the second control green.

How can I do this easily if I don't have a simple property to set?  You don't even expose the theme colors as *attached* properties, like in the code I am posting below (no complete code included for brevity) in order to make our lives easier.

   <Style x:Key="RadDropDownButtonOffice2013ColorizableStyle" TargetType="telerik:RadDropDownButton">

        <Setter Property="BorderThickness" Value="1" />
        <Setter Property="FontFamily" Value="Calibri" />
        <Setter Property="MinHeight" Value="26" />
        <Setter Property="Padding" Value="6 2" />
        <Setter Property="FontSize" Value="15" />
        <Setter Property="BorderBrush" Value="{Binding RelativeSource={RelativeSource Self}, Path=(t:Office2013Brushes.HighDarkBrush)}" />
        <Setter Property="Background" Value="{Binding RelativeSource={RelativeSource Self}, Path=(t:Office2013Brushes.BasicBrush)}" />
        <Setter Property="Foreground" Value="{Binding RelativeSource={RelativeSource Self}, Path=(t:Office2013Brushes.InvertedBrush)}" />
        <Setter Property="CornerRadius" Value="0" />
        <Setter Property="IsOpen" Value="false" />
        <Setter Property="HorizontalContentAlignment" Value="Center" />
        <Setter Property="VerticalContentAlignment" Value="Center" />
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="telerik:RadDropDownButton">
                    <Grid SnapsToDevicePixels="True">
                        <VisualStateManager.VisualStateGroups>
                            <VisualStateGroup x:Name="CommonStates">
                                <VisualState x:Name="Normal" />
                                <VisualState x:Name="MouseOver">
                                    <Storyboard>
                                        <ObjectAnimationUsingKeyFrames Storyboard.TargetName="Path" Storyboard.TargetProperty="Fill">
                                            <DiscreteObjectKeyFrame KeyTime="0" Value="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=(t:Office2013Brushes.InvertedBrush)}" />
                                        </ObjectAnimationUsingKeyFrames>
                                        <DoubleAnimation Duration="00:00:00.25" Storyboard.TargetName="OuterMouseOverBorder" Storyboard.TargetProperty="(UIElement.Opacity)" To="1" />
                                    </Storyboard>
                                </VisualState>

...... etc.................

and a static class to define the attached properties as shown below:

namespace Telerik
{
    public static class Office2013Brushes
    {
        #region Attached property BasicBrush
        //Define and register attached property
        public static readonly DependencyProperty BasicBrushProperty = DependencyProperty.RegisterAttached(
            "BasicBrush",
            typeof(Brush),
            typeof(Office2013Brushes),
            new FrameworkPropertyMetadata(new SolidColorBrush(Office2013Palette.Palette.BasicColor), FrameworkPropertyMetadataOptions.Inherits)
        );

        //Get/Set methods
        public static Brush GetBasicBrush(DependencyObject obj)
        {
            return (Brush)obj.GetValue(BasicBrushProperty);
        }
        public static void SetBasicBrush(DependencyObject obj, Brush value)
        {
            obj.SetValue(BasicBrushProperty, value);
        }
        #endregion

        #region Attached property MainBrush
        //Define and register attached property
        public static readonly DependencyProperty MainBrushProperty = DependencyProperty.RegisterAttached(
            "MainBrush",
            typeof(Brush),
            typeof(Office2013Brushes),
            new FrameworkPropertyMetadata(new SolidColorBrush(Office2013Palette.Palette.MainColor), FrameworkPropertyMetadataOptions.Inherits)
        );

        //Get/Set methods
        public static Brush GetMainBrush(DependencyObject obj)
        {
            return (Brush)obj.GetValue(MainBrushProperty);
        }
        public static void SetMainBrush(DependencyObject obj, Brush value)
        {
            obj.SetValue(MainBrushProperty, value);
        }
        #endregion

........ etc..

 The above code works fine: I can set the colors of the controls independently if I want to, or leave it to the default theme color. But, as it's easily understood, it is counter-productive for the developer to rewrite all the templates with the above logic.

The question is:

a) why you haven't created your controls to be "independently colorizable" (using attached properties or any other method you see fit) 

b) if you are planning to implement some pattern to make "colorization" easier.

I am displaying couple of rows in the normal view and whenever any of those rows are expanded, display additional 500 rows using hierarchical view.

The radgridview freezes up when trying to display the 500 rows. I tried with 50 rows and the grid did not freeze. 

I have attached a sample project which duplicates the issue. (It is actually a zip file, not jpg).

Please look at the BindableDynamicDictionary.cs.The relevant function which generates the rows dynamically is GetUserDetails.

This function is called whenever TryGetMember function is called by the radgridview with parameter "Details".

Details is the bound property for the child grid.Most of the other code can be ignored.

Can you please help identify the issue?

Please note the attachement is a .zip file. Not jpg.

I have the following Apply method that has been working:

        protected override void Apply(Telerik.Windows.Controls.TreeMap.RadTreeMapItem treemapItem, object dataItem)
        {
            BranchIntegrationDetails details = dataItem as BranchIntegrationDetails;
            SolidColorBrush brush = PickBrush(details);
           
            // Apply the color
            treemapItem.Background = brush;            // Apply additional text
            IntegrationStatisticsControl statisticsControl = new IntegrationStatisticsControl()
            {
                VerticalAlignment = System.Windows.VerticalAlignment.Bottom,
                HorizontalAlignment = System.Windows.HorizontalAlignment.Right,
                Foreground = ForegroundBrush,
                Margin = new System.Windows.Thickness(0,0,10,0)
            };
            statisticsControl.SetValue(Grid.RowSpanProperty, 2);
            Grid grid = treemapItem.ChildrenOfType<Grid>().ElementAt(1);
            grid.Children.Add(statisticsControl);
        }

The expected output can been in the first picture (see "expected.png").

 When I add the theme file into my app.xaml:

            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="StyleResources.xaml" />
                <ResourceDictionary Source="TelerikTheme/Telerik.Windows.Controls.xaml"/>
                <ResourceDictionary Source="TelerikTheme/Telerik.Windows.Controls.DataVisualization.xaml"/> <!-- this one is bad -->
                <ResourceDictionary Source="TelerikTheme/Telerik.Windows.Controls.Navigation.xaml"/>
            </ResourceDictionary.MergedDictionaries>

The control that I want to apply does not anymore (see "unexpected.png"). The same code is still working, I can see my control is added to the Grid, just I could not know why it is not showing.

I would like to know the difference between these two types, besides the obvious that one is a generic and the other is not.

Specifically:

1. Why does the generic version not support the same constructors passing an IEnumerable query?

2. Does the non generic version when passed a IEnumerable query inherently know the collection type by the result type of the query?

3. What then is the purpose of the VirtualQueryableCollectionView(IEnumerable, Type) constructor, as the second parameter Type will need to match that of the IEnumerable?

4. Is there a way within the ItemsLoading to force the non generic version to let user code handle the query (ie. e.Handled = true)

The non generic version blocks on the UI thread when requesting new items.  This is very odd coming from Telerik.  .  Even if you don't pass a query on the constructor, the ItemsLoading still blocks while loading nothing.

This blocking UI is very bad, forcing me to use the generic version which allows me to handle the ItemsLoading query (queuing the request on a background thread as is correct).

Thanks,

Mike
