[Solved] When I set RadPane.IsHidden to 'false' after it has been set to 'true' the RadPain remains invisible.

Hello. When I set RadPane.IsHidden to 'false' after it has been set to 'true' the RadPain remains invisible. Below is XAML markup:

<UserControl x:Class="DeviceReading.Views.DeviceReadingView"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:prism="http://prismlibrary.com/"

xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"

prism:ViewModelLocator.AutoWireViewModel="True">

. . . . . . . . . . . . . . . . . . .

<StackPanel Grid.Row="0" Grid.Column="0" HorizontalAlignment="Stretch" Margin="0 5 0 3" Orientation="Horizontal">

<CheckBox Content="Gas Velocity" Command="{Binding Path=ShowHideGasVelocityChartViewCommand}" CommandParameter="{Binding Path=IsChecked, RelativeSource={RelativeSource Self}}"/>

</StackPanel>

<telerik:RadDocking Grid.Row="1" Grid.Column="0" x:Name="Docking">

. . . . . . . . . . . . . . . . . . .

<telerik:RadSplitContainer>

<telerik:RadPaneGroup>

<telerik:RadPane Header="Gas Velocity" IsHidden="{Binding IsGasVelocityChartHidden, Mode=TwoWay}" prism:RegionManager.RegionName="GasVelocityChartRegion" />

</telerik:RadPaneGroup>

</telerik:RadSplitContainer>

. . . . . . . . . . . . . . . . . . .

</telerik:RadDocking>

. . . . . . . . . . . . . . . . . . .

</UserControl>

Where UserControl is Prism UserControl. Below is ViewModel code.

public class DeviceReadingViewModel : BindableBase, IConfirmNavigationRequest

{

. . . . . . . . . .

public DeviceReadingViewModel(IEventAggregator eventAggregator)

{

this._eventAggregator = eventAggregator;

this.ShowHideGasVelocityChartViewCommand = new DelegateCommand<object>(this.showHideGasVelocityChartView);

}

// Field and property controlling of the RadPain status (Visible / Hidden)

private bool _isGasVelocityChartHidden;

public bool IsGasVelocityChartHidden

{

get { return this._isGasVelocityChartHidden; }

set { this.SetProperty(ref this._isGasVelocityChartHidden, value); }

}

// The command of hidding / visualizing of the RadPain.

public DelegateCommand<object> ShowHideGasVelocityChartViewCommand { get; private set; }

private void showHideGasVelocityChartView(object parameter)

{

if ((bool)parameter == true)

this.IsGasVelocityChartHidden = false;

else

this.IsGasVelocityChartHidden = true;

}

Initially (after application loading) the RadPain is visible and the CheckBox is unchecked. When I check the CheckBox first then the RadPain become invisible. But when I uncheck the CheckBox after it then the RadPain remains invisible (but the command is fired). How to have the command display the RadPain each time the CheckBox is unchecked? What I'm doing wrong?

TreeListView Features Example

Hello,

I was wondering if there are any existing examples that demonstate the following TreeListView features:

Custom template for Drag/Drop behavior ("drop node1 before node2" as a preview, for example)
Dragging a TreeListView item into another control that accepts drop (passing a DataObject through a DragEventArgs)

Thanks,
Ryan

Populate a tile style from resource dictionary

At the moment in my resource dictionary I have a telerik Tile control. When it's instantiated a second time I receive the follow error `Specified Visual is already a child of another Visual or the root of a CompositionTarget`

public void ListIcon()

{

var tile = Application.Current.Resources["ListTile"] as Tile;

Tiles.Add(tile);

}

app.xaml

<telerik:Tile x:Key="Calendar" TileType="Double" Background="#FF79256B" Group="Other">

<telerik:RadCalendar x:Name="calendar"

FontFamily="Segoe UI"

FontSize="10"

controls:StyleManager.Theme="Windows8"

VerticalAlignment="Top" HorizontalAlignment="Center"

SelectionMode="Extended"

IsTodayHighlighted="True" ViewsHeaderVisibility="Collapsed"

SelectedDate="{Binding SelectedDate, Mode=TwoWay}"

Culture="en-US"

DayTemplateSelector="{StaticResource EventDayTemplateSelector}"/>

</controls:Tile>

Everytime a new user is logged in, ListIcon() is called. If I log out and log into a second user the error occurs. May I ask how do I resolve this.

AutoCompleteBox SelectedItems Binding problem

Hi,

I have a Listbox with a datatemplate:

<DataTemplate x:Key="ListBoxDataTemplate">

<StackPanel Orientation="Horizontal">

<TextBlock Text="{Binding FieldName, Mode=TwoWay}" Width="120" />

<telerik:RadAutoCompleteBox Width="197" Name="autoCompBox"

Background="Beige" SelectionMode="Multiple" TextSearchMode="StartsWith"

TextSearchPath="Code" AutoCompleteMode="Suggest"

DropDownItemTemplate="{StaticResource ContactSearchTemplate}" DataContext="{Binding}"

ItemsSource="{Binding DataContext.Codes, Mode=TwoWay, RelativeSource={RelativeSource AncestorType=telerik:RadListBox}}"

SelectedItems="{Binding Path=AssociatedCodes, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}">

</telerik:RadAutoCompleteBox>

</StackPanel>

</DataTemplate>

My ListBox ItemsSource property is binded to a property in ViewModel named:

public List<ReportDataAssociation> ReportDataAssociation

{

get { return m_reportDataAssociation; }

set { m_reportDataAssociation = value; OnPropertyChanged("ReportDataAssociation"); }

}

This property is an object with the following properties:

string FieldName;

ObservableCollection<ReportCodes> AssociatedCodes;

The FieldName is binded to the TextBlock
The AssociatedCodes is binded to the SelectedItemsProperty of each AutoCompleteBox.

I load an ObservableCollection<ReportCodes> named Codes which is binded to all AutoCompleteBoxes.
The AssociatedCodes is a property of ReportDataAssociation which is binded to SelectedItems.
Any ReportCode I add to the AssociatedCodes' List is from the ObservableCollection<ReportCodes> named Codes
so the referece to the object is the same.

The problem is:
When I select or delete some items from some autocompletebox,
the property AssociatedCodes does not change.
When I change the property AssociatedCodes at runtime, the selectedItems in autocompletebox
don't change.
I think it's a binding problem but i can't figure out what it is.
Maybe because the AutoCompleteBoxes are in a template.

I tried to bind the selectedItems in many ways, the binding shown above is one of my many tries..
Please help
Thanx in advance

[Solved] Dll conflicts with telerik reporting dll

Hi telerik support

I have a telerik license for the wpf controls and we are using 2012 version (2012.2.725.40).

Now, i want to try the telerik reports.

For this i'd created a separate solution (Visual studio solution) which contains 2 projects (one for reporting lib and another one for wpf) which is working fine with no issues.

Now the problem is when i try to integrate with my existing wpf application, what i did as follows

1. Added the ReportLib project to the existing solution

2. Added new window for the report in which added a reportViewer control ( as given by the telerik samples, which is also working fine as i said above)

Now the issue is, Since i'm already using telerik controls inside my application, the report viewer is not showing in the window

Can you please help me, how to resolve this?

NOTE: I'd also tried adding the latest dlls( Telerik.Windows.Data.dll, Telerik.Windows.Controls.Input,Telerik.Windows.Controls.Navigation, Telerik.Windows.Controls). by doing so, my existing controls are not working (build error)

Getting Started with UriImageProvider

I know there's probably a simple solution to this problem but I cant find it for the life of me. Im trying to use RadMap in order to display a floor plan that I can later add points to similar to the demo shown here. The issue that im facing is that I cant get the Floor plan to appear. Ive tried using different images with different sizes and that has yet to yield any results when I run it I simply see a blank canvass with the coordinates. The floor plan is saved as a FloorMap.png and for now I have placed it in my desktop. I was not sure how to set the GeoBounds so I have left them as they appear in the sample used here
