Replace view/viewmodel of already existing TileView item

Hello!

I have added some TileViewItems to my TileView using RegionManager.AddToRegion() and it's working fine (I think RequestNavigate would do the trick also).

Now I would like to allow user to configure each tile separately. One configuration option would require me to change the configured tile to show another view (and maybe use its own viewmodel also).

Is this possible?

Now that I try RequestNavigate to this TileView region it always adds a new TileItem and that is not what I want in this case. I'd like to be able to only change the view/viewmodel for the tile I'm configuring.

Br,

Cannot load document

Hi,
Can You please tell me why this code is not working. In code behind:

private void Button_Click(object sender, RoutedEventArgs e)

{

OpenFileDialog ofd = new OpenFileDialog();

ofd.Filter = "Pdf-Dateien (*.pdf)|*.pdf";

if (ofd.ShowDialog() == true)

{

this.documentStream = new FileStream(ofd.FileName, FileMode.Open);

RadFixedDocument doc = new PdfFormatProvider(this.documentStream, FormatProviderSettings.ReadOnDemand).Import();

this.pdfViewer.Document = doc;

}

}

and in XAML:


<telerik:RadPdfViewer Grid.Row="1" x:Name="pdfViewer" Grid.ColumnSpan="2"/>

System report no errors, simply nothing is showing in viewer.



Best Regards

Can AutoCompleteBox work like a TextBox with Autocomplete?

Hi,

I thought (from the first look it seems so) AutoCompleteBox is what I'm looking for.
Searching the help I found not a single word how to bind Text with this control.

Further investigations brought me to a mix of "SearchText" and "SelectedItems" - which barely works

Anyhow - what I expected was:
a.) A TextBox (with validation and binding for the text)
b.) Suggestions with the possibility to choose (and also change) an item

Or (except for Validation) - the thing you see in Internet Explorer.

Can I do this with RadAutoCompleteBox?

Approach:
User has give a "Reason" for something.
In my Model I have Item.Reason - which must be filled.
Since the resons are often the same - I have a list of default reasons - as suggestions whild entering text.
The user chan choose an existing one - his own one - at the end there is text in the box - which has to be validated (IDataErrorInfo)
If it fails - red markers.....

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 :)
