Feature Request: Frozen Columns

It would be a nicer UX if a user did not have to first move the frozen column indicator in order to resize a column.

I am happy to style it myself this way but I am struggling to find the correct element, is it the PART_FrozenColumnsPreview element?

Regards,
Maurice

Is it supported to add ContextMenu on a RadContextMenu?

Hello, my case is: I have a RadContextMenu, and there's a RadListBox filling the RadMenuGroupItem of the RadContextMenu. And then I added a TextBlock in the ItemTemplate of the RadListBox. And finally, I added a ContextMenu on this TextBlock, this ContextMenu on TextBlock didn't work. Right clicking on the TextBlock which is also the an Item of the RadListBox, no ContextMenu pop up, nothing happened. So what's the reason of it? Is this kind of case supported? Thanks for any comments, that would be great help for me, thanks a lot.

Can't set a theme for PDF Viewer

Hi, I'm trying to use the PDF Viewer control, everything works nicely except for one thing,

he toolbar theme won't change no matter what I select.

            <telerik:RadPdfViewerToolBar x:Name="pdfViewTools"
                                         RadPdfViewer="{Binding ElementName=pdfViewer, Mode=OneTime}"
                                         telerik:StyleManager.Theme="Fluent"
                                         HasClockwiseButton="False"
                                         HasCounterclockwiseButton="False"
                                         HasOpenButton="False"
                                         HasPageDownButton="False"
                                         HasPagesCountGroup="False"
                                         HasPageUpButton="False"
                                         HasSignatureButton="False"/>
            <telerik:RadPdfViewer x:Name="pdfViewer"
                                  DataContext="{Binding CommandDescriptors, ElementName=pdfViewer}"
                                  Grid.Row="1"
                                  telerik:StyleManager.Theme="Fluent"
                                  telerik:RadPdfViewerAttachedComponents.RegisterContextMenu="True"/>

Where am I going wrong?

RadScheduleView - different appointment types

Hello,

I'm working on a scenario where i have to use 2 different types of appointments, with different properties. both share a common abstract base class, which is derived from the Appointment Class.

public abstract class MyBaseClass : Appointment

{

private string _designation;

public string Designation

{

get { return this.Storage<MyBaseClass>()._designation; }

set

{

var storage = this.Storage<MyBaseClass>();

if (value == storage._designation) return;

storage._designation = value;

this.OnPropertyChanged(() => this.Designation);

}

public class DerivedType : MyBaseClass

{

private string _longText;

public string LongText

{

get { return this.Storage<DerivedType>()._longText; }

set

{

var storage = this.Storage<DerivedType>();

if (value == storage._longText) return;

storage._longText = value;

this.OnPropertyChanged(() => this.LongText);

}

public class OtherType : MyBaseClass

{

private bool _myBool;

public bool MyBool

{

get { return this.Storage<OtherType>()._myBool; }

set

{

var storage = this.Storage<OtherType>();

if (value == storage._myBool) return;

storage._myBool = value;

this.OnPropertyChanged(() => this.MyBool);

}

When using a ListBox, i would simply put multiple datatemplates with DataType={x:Type ...} into the listbox resources. As this did not work, I tried to override ScheduleViewDataTemplateSelector:

public override DataTemplate SelectTemplate(object item, DependencyObject container, ViewDefinitionBase activeViewDefinition)

{

Occurrence o = (item as Occurrence);

if (o.Appointment is DerivedType)

return this.DerivedTypeTemplate;

...

}

<local:TelerikScheduleTemplateSelector x:Key="ScheduleTemplateSelector">

<local:TelerikScheduleTemplateSelector.DerivedTypeTemplate>

<DataTemplate>

<Grid Background="LightGray">

<Grid.RowDefinitions>

<RowDefinition MinHeight="15"/>

<RowDefinition Height="*"/>

</Grid.RowDefinitions>

<Label Grid.Row="0" Content="{Binding Appointment.LongText}" />

<Label Grid.Row="1" MinHeight="30" Margin="2" Background="Green" />

</Grid>

</DataTemplate>

<local:TelerikScheduleTemplateSelector.OtherTypeTemplate>

<DataTemplate>

<Grid Background="LightGoldenrodYellow">

<Grid.RowDefinitions>

<RowDefinition Height="20"/>

<RowDefinition Height="*"/>

</Grid.RowDefinitions>

<CheckBox Grid.Row="0" Margin="2" IsChecked="{Binding Appointment.MyBool}" Content="asdf" />

</Grid>

</DataTemplate>

</local:TelerikScheduleTemplateSelector.OtherTypeTemplate>

</local:TelerikScheduleTemplateSelector>

this seems to work partially, but I found some problems:

-> the bindings are not recognized, as I cannot set the DataType to DerivedType or to OtherType
-> Sometimes when switching to other weeks in the scheduleview, I get Binding Errors, because of a missing MyBool Property on DerivedType, and vice-versa

Is there an easier way to get different looks based on the type of the appointment? Could you point me in the right direction, or maybe provide a small sample?

Thanks a lot!

WPF RadDocking AutomationId not set

Hi,

we are using the rad docking and set a automationid to all levels (RadDocking, RadSplitContainer, RadPaneGroup and RadPane) but if we let the CUIT run it needs much time or he doesn´t find the control.

Also if we check the UI with AccChecker we can see that there is no AutomationId set.

If have downloaded a example from this thread:

https://www.telerik.com/forums/cuit-is-failing-perform-actions-on-the-controls-placed-inside-the-radpanegroup#g4MK_X_CbU-XMfaGOlK9vg

But it doesn´t work on my computer and I can see that there is no automationid set.

See AutomationIds in the Code.jpg file.

In the file ACC.jpg you could see that there is no AutomationId found.

Currently it´s not possible to upload the source code because it´s to big and it´s not allowed.

Could you tell me where we miss something or is it a bug?

Thanks for your help.

FixedDocumentViewers Exception

I have a Window that I have dropped a RadPdfViewer on, the system added Telerik.Windows.Controls, Telerik.Windows.Controls.FixedDocumentViewers, Telerik.Windows.Documents.Core, and Telerik.Windows.Documents.Fixed.

I have done nothing else, when I run the app I get an Exception:

Listbox Custom DragDropBehavior

Hi!

I'm trying to use binding in DragDropBehavior of RadListBox like this

View gets viewmodel via injection

public partial class MyView : UserControl
{
public MyView (ViewModels.MyViewModel viewModel)
{
InitializeComponent();
DataContext = viewModel;
}
}

Behavior code:

public class MyDragDropBehavior : Telerik.Windows.DragDrop.Behaviors.ListBoxDragDropBehavior
{
public override bool CanDrop(Telerik.Windows.DragDrop.Behaviors.DragDropState state)
{
return state.IsSameControl;
}

public override void Drop(Telerik.Windows.DragDrop.Behaviors.DragDropState state)
{
base.Drop(state);
DropCommand.Execute(null);
}

public ICommand DropCommand
{
get { return (ICommand)GetValue(DropCommandProperty); }
set { SetValue(DropCommandProperty, value); }
}

public static readonly DependencyProperty DropCommandProperty =DependencyProperty.Register("DropCommand", typeof(ICommand), typeof(MyDragDropBehavior), new PropertyMetadata(null));
}

Items binding is working well. Behavior is working but binding to DropCommand is not. I obtain binding error:

Cannot find source for binding with reference 'RelativeSource FindAncestor, AncestorType='System.Windows.Controls.UserControl', AncestorLevel='1''. BindingExpression:Path=DataContext.DropCommand; DataItem=null; target element is 'MyDragDropBehavior' (HashCode=25707777); target property is 'DropCommand' (type 'ICommand')

ViewModel is

public class MyViewModel
{
public MyViewModel()
{
DropCommand = new DelegateCommand(OnDrop);
Items = new ObservableCollection<MyItem>();
}
public ObservableCollection<MyItem> Items { get; set; }
public DelegateCommand DropCommand { get; set; }

private void OnDrop(){}
}

What is wrong?

Reg: PIVOT GRID Custome View Save

Hello Team,

We are into the WPF application development. We are using the RadPivotGrid control to view the information grid. To view the same BI format we are saving the view(i.e in XML format). When we save the view. our application is saving the data in our database in XML format. Please review the attached file which is saved in xml format. But we want to know the what is the <ValueTypes> node which is created while saving the view. We want to know what is the version number saved in the file. Is there any relation with .net framework version while generating the XML string?

Below is the XML string.
