RadMaskedTextInput Default Validation.ErrorTemplate

Hi

I'm currently using a MaskedTextInput control and have noticed that the default error template used to display validation errors is different to that used by other controls on my form (TextBox, RadCombo, RadDatePicker etc).

I'm using the StyleManager to apply the Windows7 theme to all the controls...

I don't want to create a custom template and apply this to the MaskedTextInput as described in other posts, I simply want to use the same standard error template (Windows7 theme) that the other controls all seem to use so that my UI is consistent...

Please can you suggest how this may be achieved?

Thanks

Jamie

close and show RadDocking programmatically

I have two buttons one to show and other to close my RadDoking. By default, the RadDoking is deactivated(not show), when I press the show button, the RadDoking opens but on I prese my close button it does not work

My Xaml :

<telerik:RadDocking Grid.Column="1" x:Name="radDocking1" Grid.Row="1" Margin="0 0 0 10" BorderThickness="0"
Visibility=

"{Binding Hidden,ConverterParameter=True, Mode=TwoWay,  Converter={StaticResouce                                    CvtVisibilityConverter}}"

Padding="0" >

<telerik:RadSplitContainer InitialPosition="FloatingOnly"

telerik:RadDocking.FloatingLocation="450, 250" >

<telerik:RadPaneGroup >

<telerik:RadPane Title="My Pane"

CanDockInDocumentHost="False"

CanUserClose="False" CanUserPin="False" >

</telerik:RadPane>

</telerik:RadPaneGroup>

</telerik:RadSplitContainer>

</telerik:RadDocking>

My ViewModel

public class MyViewModel: ViewModelBase

{

public MyViewModel

{

Hidden = true ;

}

public bool Hidden

{

get

{

return hidden;

}

set

{

hidden = value;

OnPropertyChanged("Hidden");

}

private ICommand showCommand;

private ICommand closeCommand;

public ICommand CloseCommand

{

get

{

if (closeCommand == null)

closeCommand = new RelayCommand(param => this.CloseCommandEvent());

return closeCommand;

}

private void CloseCommandEvent()

{

Hidden = true;

}

public ICommand showCommand

{

get

{

if (showCommand == null)

showCommand = new RelayCommand(param => this.ShowCommandEvent());

return showCommand;

}

private void ShowCommandEvent()

{

Hidden = false;

}

My Converter

public class VisibilityConverter : IValueConverter

{

public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)

{

if (value == null || !(value is Boolean))

return Visibility.Collapsed;

var parm = parameter ?? false;

bool flip;

Boolean.TryParse(parm.ToString(), out flip);

var visible = flip ? !((bool)value) : (bool)value;

return visible ? Visibility.Visible : Visibility.Collapsed;

}

public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)

{

throw new NotImplementedException();

}

I do not understand why it does not work, Thank you for your help :)

Drop a dragged row on last row is imposible

Hi Telerik
I have been working on a project with you brillant TreelistView for over a year now - so glad I bought your product!

But heres my little problem - and it is also not working in your own example:
In your DragDrop-example for radTreeListView, it is not posible to drop an item on the last item.
It is posible to drop on all the other elements - except the last one.
Could you please help me with a workaround?

With kind regards from Kenneth

Cannot set cell into edit mode

Per this post (http://www.telerik.com/community/forums/wpf/gridview/edit-mode-and-the-keyboardcommandprovider.aspx) it was recommended that I implement key handling for navigation by handling PreviewKeyDown. This was working fine up until the latest version of the GridView control, in my case, Q1 2011. If I press the down arrow while in a text box in edit mode, it should move down, select the next box and then go into edit mode. Now, the cursor does move down but the cell does not enter edit mode. This is the code that's been working for some time:

        private void HandleKeyDown(KeyEventArgs e)
        {
            if (e.Key == Key.Down)
            {
                RadGridViewCommands.MoveDown.Execute(null);
                RadGridViewCommands.SelectCurrentUnit.Execute(null);
                RadGridViewCommands.BeginEdit.Execute(null);
 
                e.Handled = true;
            }
        }

[Solved] Binding Error with internal builds

Hi,

I have a solution using RadDiagram in RadDocumentPane.
This Solution worked with RadControls_for_WPF_2013_3_1204_Dev.
After installing RadControls_for_WPF_2013_3_1306_DEV_hotfix the (see below) errors occured.
Installing RadControls_for_WPF_2013_3_1313_DEV_hotfix did not solve the problem.

My (Reduced) XAML:

<Grid DataContext="{Binding}" x:Name="grdHolder">

<Grid.RowDefinitions>

<RowDefinition Height="Auto" />

<RowDefinition Height="*" />

</Grid.RowDefinitions>

<StackPanel Orientation="Horizontal">

<telerik:RadToggleButton IsChecked="{Binding IsPropertiesWindowHidden, Mode=TwoWay, Converter={StaticResource bInvertedConverter}}" Content="Eigenschaften" ToolTip="Eigenschaften anzeigen / verbergen" Margin="6,2" Height="24" HorizontalAlignment="Left" />

<telerik:RadToggleButton IsChecked="{Binding IsDetailsWindowHidden, Mode=TwoWay, Converter={StaticResource bInvertedConverter}}" Content="Details" ToolTip="Detailsvorschau anzeigen / verbergen" Margin="6,2" Height="24" HorizontalAlignment="Left" />

<telerik:RadToggleButton IsChecked="{Binding IsConditionsWindowHidden, Mode=TwoWay, Converter={StaticResource bInvertedConverter}}" Content="Bedingungen" ToolTip="Bedingungsfenster anzeigen / verbergen" Margin="6,2" Height="24" HorizontalAlignment="Left" />

</StackPanel>

<telerik:RadDocking Grid.Row="1">

</telerik:RadPane.Content>

</telerik:RadPane>

</telerik:RadPaneGroup>

</telerik:RadSplitContainer>

</telerik:RadDocking>

</Grid>

The Errors:
System.Windows.Data Error: 4 : Cannot find source for binding with reference 'ElementName=grdHolder'. BindingExpression:Path=DataContext; DataItem=null; target element is 'Grid' (Name=''); target property is 'DataContext' (type 'Object')
System.Windows.Data Error: 4 : Cannot find source for binding with reference 'ElementName=dGram'. BindingExpression:(no path); DataItem=null; target element is 'XDiagramNavigationPane' (Name=''); target property is 'Diagram' (type 'RadDiagram')
System.Windows.Data Warning: 4 : Cannot find source for binding with reference 'ElementName=DropDownButtonElement'. BindingExpression:Path=IsChecked; DataItem=null; target element is 'DropDownMenu' (Name='DropDownMenuElement'); target property is 'IsOpen' (type 'Boolean')

The last Error is known for a long time (and also exists in my working solution - but has no negative effects so I simply ignored it)
See:
http://www.telerik.com/community/forums/wpf/docking/binding-error-using-raddocking-with-documenthost.aspx

But the first two (for grdHolder and dGram) occurred first after installing the hotfixes.
The result - no Diagram content.

A first fix was to change the xaml like this:

<telerik:RadDocking Grid.Row="1">

<telerik:RadDocking.DocumentHost>

<telerik:RadSplitContainer>

<telerik:RadPaneGroup>

<telerik:RadDocumentPane CanUserClose="False" CanFloat="False" CanUserPin="False" Visibility="Collapsed">

<Grid >

Removing the DataContext binding on the Grid brings back the diagrams functionality - but still the error:
System.Windows.Data Error: 4 : Cannot find source for binding with reference 'ElementName=dGram'. BindingExpression:(no path); DataItem=null; target element is 'XDiagramNavigationPane' (Name=''); target property is 'Diagram' (type 'RadDiagram')

is there - so I have an empty NavigationPane.
