I thought it would be something like the loaded event but that appears to not be the case.  Please advise, thanks.

public partial class Menu : RadPane
{
public Menu()
{
InitializeComponent();
DataContext = new MenuViewModel(mc);
Loaded += Menu_Loaded; //breakpoint here executes

}

void Menu_Loaded(object sender, RoutedEventArgs e)
{
Loaded -= Menu_Loaded; // never executes
((MenuViewModel)DataContext).ShowMenu();
}

protected override void OnLoaded(object sender, RoutedEventArgs e)
{
base.OnLoaded(sender, e); // never executes
((MenuViewModel)DataContext).ShowMenu();
}

}

Hello!

The datacontext of my custom RadRibbonBackstage changes after the ribbonview is fully loaded.

Doesn't matter if I set it's datacontext before or after the InitializeComponent() call in the constructor, I even tried to set it through xaml.

For now I can set the datacontext in the Loaded+= event of my backstage, but seems a crappy solution. I would like to know if this is a correct behavior of the control, or if I am doing something wrong.

I have attached a project where youll be able to easily reproduce the situation, change the extension from png to zip.

Hi,

how do i change the border color and tooltip when hovering the mouse over a palette color?.

Thanks.

I have a MainWindow with various tabs. One of them is a Contextual Tab. I want to set the Contextual Tab's IsActive to the boolean IsFormAgentVisible value which is a public property in my MainWindow.xaml.cs

I'm entirely new to WPF so I'm not sure a normal public property is the best way to go here. When I click on a ribbon button to launch a specific Window I set the IsFormAgentVisible to true. At this point I want to the contextualGroupFormAgents ContextualGroup below to be updated so that IsActive is now true. Hopefully this is a pretty simple task to perform. Thanks.


Contextual Tab code from the MainWindow.xaml:
             <telerik:RadRibbonView.ContextualGroups>
                <telerik:RadRibbonContextualGroup x:Name="contextualGroupFormAgents" />
            </telerik:RadRibbonView.ContextualGroups>

            <telerik:RadRibbonTab Header="Form Agents" ContextualGroupName="contextualGroupFormAgents">
                <telerik:RadRibbonGroup Header="Primary Details">
                    <telerik:RadRibbonDropDownButton Content="Change Primary Details" Click="ChangePrimaryDetailsDropDown_Click" />
                    <telerik:RadRibbonButton Content="Obsolete Forms"/>
                </telerik:RadRibbonGroup>
                <telerik:RadRibbonGroup Header="Process Status">
                    <telerik:RadRibbonDropDownButton Content="Update Process Status" Click="UpdateProcessStatusDropDown_Click" />
                </telerik:RadRibbonGroup>
                <telerik:RadRibbonGroup Header="Memos">
                    <telerik:RadRibbonButton Content="Add Memos"/>
                </telerik:RadRibbonGroup>
                <telerik:RadRibbonGroup Header="Submittal Details">
                    <telerik:RadRibbonDropDownButton Content="Change Submittals" Click="ChangeSubmittalsDropDown_Click"/>
                </telerik:RadRibbonGroup>
            </telerik:RadRibbonTab>

MainWindow.xaml.cs public property:
          public bool IsFormAgentVisible { get; set; }        

Hi, We are binding a list with both RadListBox(s) (small and large icon view) and RadCarousel to allow the user to see the same list in multiple ways. We need to allow the ability to drag items. At this point, we have enabled the List box to allow Drag and we would like to do the same thing with the RadCarousel (Drag the top most item/ image in the Carousel). Please help us with some sample code to enable the drag behavior from Carousel.
In the below code, I have both the RadListBox(s) and Carousel code.
​

<telerik:RadGridView ItemsSource="{Binding Path=ShipCollection, UpdateSourceTrigger=PropertyChanged, ValidatesOnDataErrors=true, NotifyOnValidationError=true, Mode=TwoWay}"
                                     SelectionMode="Single" SelectedItem="{Binding Path=SelectedEvent, UpdateSourceTrigger=PropertyChanged, ValidatesOnDataErrors=true, NotifyOnValidationError=true, Mode=TwoWay}" 
                                     AutoGenerateColumns="False" ShowGroupPanel="False" RowIndicatorVisibility="Collapsed" CanUserDeleteRows="False" IsFilteringAllowed="True">
                    <telerik:RadGridView.Columns>
                        <telerik:GridViewDataColumn Header="NASA Ship" DataMemberBinding="{Binding Ship, UpdateSourceTrigger=PropertyChanged, ValidatesOnDataErrors=true, NotifyOnValidationError=true, Mode=TwoWay}" Width="*" IsReadOnly="True" />
                       
                        <!--<telerik:GridViewDataColumn DataMemberBinding="{Binding Visible, Mode=TwoWay}" FilterMemberPath="Visible" IsFilterable="True" ShowFilterButton="False" />-->

Is there an easy way using the GridView to hide rows?

I have a GridView that has rows with possible components and I must add or remove them in a list. Like in the picture

Thanks,
Sieg

Basically I have a parent-child situation I want to display in a flat grid. But for a series of consecutive rows with the same parent, I only want the first row to show the parent values.

It is basically the same as this question, but for WPF instead of WinForms.

How is it possible to achieve this?

 
 How to hide programaticly rows?
 
 bool: Visible is property in collection NasaShipsCollection
 


public partial class EventField : IDataErrorInfo, IFilterDescriptor
{

 {
  return instance;
 }#endregion
}
public class BoolenFilteringControl :UserControl, IFilteringControl
{
 private bool _isActive; public void Prepare(GridViewColumn columnToPrepare)
 {
  // throw new System.NotImplementedException();
 } public bool IsActive

  get
  {
