[Solved] Custom cursor is ignored in the title area

Hello. If I set a custom cursor to a RadWindow, when I hover the pointer over the title area of the window, the custom cursor isn;t displayed, instead the standard arrow cursor is shown.

Is there a way to have the custom cursor displayed in the title area as well?

Moving to next cell with Enter Key

I have a Radgridview with a custom cell which is editable. When the enter key is pressed it appropriately moves to the next row down. When a value is entered into the second row and the user presses the enter key it does not move to the next row. Is there a way to always have the cursor move to the next cell down when the enter key is pressed and not just once?

How to control the plot order for multiple series

for example,

Series 1: X: P1 P1 P2

Y 2 3 4

Series 2 X:P1 P1 P2

Y: 5 6 7

If they are plotted in graph as bar series. I expected the plot order as (series1 ->P1,2) (series2->P1,5) (series 1->P1,3) (series 2->P1,6) (series1 ->P2,4) (series2 ->P2,7) . that means all the P1 category will be grouped together and has the value order as (2,5,3,6). And P2 category has value order(4,7)

but actually, it looks like P1 category has the value order as (2,3,5,6) and P2 category has value order(4,7)

in order to achieve what I want, I have to flatten the two series (series1 and series 2) into one series. But that approach is not exactly what I want. Thank you

[Solved] Inconsistent themes

I've noticed that there are some differences between several controls regarding watermark styling and left padding. It becomes quite visible if you put them next to each other. The left column only contains watermarkcontent and the right one contains text. I'm using the Windows7Theme but it looks the same in several other themes aswell.

<StackPanel Orientation="Horizontal">

<StackPanel Width="200" HorizontalAlignment="Left">

<telerik:RadWatermarkTextBox Margin="3" WatermarkContent="RadWatermarkTextBox"/>

<telerik:RadAutoCompleteBox Margin="3" WatermarkContent="RadAutoCompleteBox"/>

<telerik:RadMaskedTextInput HorizontalAlignment="Stretch" Margin="3" EmptyContent="RadMaskedTextInput" TextMode="PlainText"/>

<telerik:RadComboBox IsEditable="True" Margin="3" EmptyText="RadComboBox"/>

</StackPanel>

<StackPanel Width="200" HorizontalAlignment="Left">

<telerik:RadWatermarkTextBox Margin="3" Text="RadWatermarkTextBox"/>

<telerik:RadAutoCompleteBox Margin="3" SearchText="RadAutoCompleteBox"/>

<telerik:RadMaskedTextInput HorizontalAlignment="Stretch" Margin="3" Value="RadMaskedTextInput" TextMode="PlainText"/>

<telerik:RadComboBox IsEditable="True" Margin="3" Text="RadComboBox"/>

</StackPanel>

[Solved] Bar Chart Label Selection

I'm developing a bar chart where when the label is selected I need to set the color of that label as well as call an event handler (a different one than what I have set up for the bar selection).

Is there a property that enables this, similar to the ChartSelectionBehavior? Starting with one of the examples I found (see XAML below) I've been able to get the bar selection working and I made the label change color on mouse over, but this isn't what I need - it needs to function more like the bar selection.

DnD not working since 2016.3.1024.45

Hello,

dnd between two gridviews is not working since the upgrade from 2016.3.914.45 to 2016.3.1024.45.

In the OnDragInitialize methode I'm assigning a DnD object to eventargs.Data which is not recognized by the drop table "eventargs.Data.GetDataPresent()".
It worked perfectly in the previous version but caused yesterday a lot of trouble after upgrading an application to the latest version :(

private void OnDragInitialize(object sender, Telerik.Windows.DragDrop.DragInitializeEventArgs ea) {
string displayText = "";
var selectedRows = ((RadGridView)sender).SelectedItems;
if (selectedRows.Count == 0) {
return;
}

var list = new List<PsCore.DataObjects.DragAndDrop.BusinessPartnerEntityDndDO>();
foreach (PsCore.Interfaces.IDndDataObject row in selectedRows) {
list.Add(new PsCore.DataObjects.DragAndDrop.BusinessPartnerEntityDndDO(row.PrimaryID, row.DisplayText));
displayText = row.DisplayText;
}
ea.Data = new PsCore.DataObjects.DragAndDrop.DndContainerDO<PsCore.DataObjects.DragAndDrop.BusinessPartnerEntityDndDO>(list, displayText);

ea.DragVisual = new ContentControl { ContentTemplate = LayoutRoot.Resources["DraggedItemTemplate"] as DataTemplate, Content = ea.Data };
this.dragVisualTemp = ea.DragVisual;
ea.DragVisualOffset = new Point(ea.RelativeStartPoint.X, ea.RelativeStartPoint.Y - 20);
ea.AllowedEffects = DragDropEffects.All;
ea.Handled = true;
}

private bool IsDndObjectAllowed(DragEventArgs ea) {
Type dndContainerType = typeof(DndContainerDO<BusinessPartnerEntityDndDO>);
if (!ea.Data.GetDataPresent(dndContainerType)) {
Console.WriteLine("DND object NOT recognized");
return false;
}
var draggedData = (ea.Data as DataObject).GetData(dndContainerType) as DndContainerDO<BusinessPartnerEntityDndDO>;
if ((draggedData != null) && (draggedData.Items.GetType() == typeof(List<BusinessPartnerEntityDndDO>))) {
return true;
}
return false;
}

Best Regards,

Raul

Command Binding MVVM

Hello,

i am trying to implement a command (LeftDoubleClick) from my view to viewmodel using mvvm pattern (without code behind and event).

I saw some samples but they don't work for me!

Please can someone tell me i i am making wrong?

xaml:

<telerik:RadGridView x:Name="radGridView" Margin="8" ItemsSource="{Binding Source={StaticResource DataSource}}"

IsReadOnly="True" >

<telerik:RadGridView.InputBindings>

<MouseBinding Gesture="LeftDoubleClick" helpers:AttachedMouseBinding.Command="{Binding Path=DoubleClickCommand}" />

</telerik:RadGridView.InputBindings>

</telerik:RadGridView>

.cs:

public class UC_SEGridViewModel : InterfaceDescription.ViewModels.ViewModelBase

{

private ViewModelMaster viewModelMaster;

public ICommand DoubleClickCommand { get; set; }

public UC_SEGridViewModel()

{

DoubleClickCommand = new RelayCommand(GridItemDoubleClick);

}

private void GridItemDoubleClick(object obj)

{

//do something

}

but i don't reach my callback method (GridItemDoubleClick) when i set a breackpoint

the helper:

public class AttachedMouseBinding

{

const string PROPERTYNAMECOMMAND = "Command";

public static readonly DependencyProperty CommandProperty = DependencyProperty.RegisterAttached(PROPERTYNAMECOMMAND, typeof(ICommand),

typeof(AttachedMouseBinding), new FrameworkPropertyMetadata(CommandChanged));

private static void CommandChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)

{

FrameworkElement fe = d as FrameworkElement;

ICommand command = e.NewValue as ICommand;

InputBinding inputBinding = new InputBinding(command, new MouseGesture(MouseAction.LeftDoubleClick));

fe.InputBindings.Add(inputBinding);

//if (inputBinding != null)

// inputBinding.Command = command;

}

public static ICommand GetCommand(DependencyObject obj)

{

return (ICommand)obj.GetValue(CommandProperty);

}

public static void SetCommand(DependencyObject obj,ICommand value)

{

obj.SetValue(CommandProperty, value);

}

Thanks for your help,

Richard
