AutoCompleteBox CustomFilteringBehavior with Single SelectionMode

Hi,
I'm Interest for the AutoCompleteBox Control but i have this issue:

Ihave this CustomFilteringBehavior:

public class CustomFilteringBehavior : FilteringBehavior

{

public override System.Collections.Generic.IEnumerable<object> FindMatchingItems(string searchText, System.Collections.IList items, System.Collections.Generic.IEnumerable<object> escapedItems, string textSearchPath, TextSearchMode textSearchMode)

{

var searchTextToUpper = searchText.ToUpper();

var matchingItems = items.OfType<Person>().

Where(x => x.FirstName.ToUpper().Contains(searchTextToUpper) || x.LastName.ToUpper().Contains(searchTextToUpper)

|| (x.FirstName + " " + x.LastName).ToUpper().Contains(searchTextToUpper));

return matchingItems.Where(x => !escapedItems.Contains(x));

}

and in my main page i used this CustomFilteringBeahvior:

<UserControl.Resources>

<local:ViewModel x:Key="ViewModel" />

<local:CustomFilteringBehavior x:Key="CustomFilteringBehavior" />

<DataTemplate x:Key="CustomItemTemplate">

<StackPanel Orientation="Horizontal">

<TextBlock Text="{Binding FirstName}" />

<TextBlock Text=" " />

<TextBlock Text="{Binding LastName}" />

</StackPanel>

</DataTemplate>

</UserControl.Resources>

<Grid x:Name="LayoutRoot" Background="White" DataContext="{StaticResource ViewModel}">

<StackPanel>

<telerik:RadAutoCompleteBox ItemsSource="{Binding People}"

FilteringBehavior="{StaticResource CustomFilteringBehavior}"

DropDownItemTemplate="{StaticResource CustomItemTemplate}"

BoxesItemTemplate="{StaticResource CustomItemTemplate}"

SelectionMode="Single"

AutoCompleteMode="Suggest" />

</StackPanel>

</Grid>

when typing :

in SelectionMode="Multiple" all works fine but
in SelectionMode="Single" the result after selection is :

is there any idea for this behavior ?

Thank you in advance,

AutoCompleteBox

Could not load assembly Telerik.Windows.Controls.Navigation

Hello,

I downloaded the trial version of RadControls for Silverlight and I'm having problems loading the assemblies. I extracted the downloaded contents to My Documents and added a reference to the DLLs, and got this error:

Could not load file or assembly 'Telerik.Windows.Controls.Navigation, Version=2008.2.826.0, Culture=neutral, PublicKeyToken=9c7324f9b8e4111a' or one of its dependencies. The system cannot find the file specified.

I tried copying the DLLs to my bin directory and resetting the references but still got the same error. Does anyone know what could be the cause of this problem?

Thanks,

Daniel

How do I enable drag re-ordering without drop?

I have a single RadListBox and I just want to enable drag re-ordering with no drop capabilities (the documentation is this area is horribly unclear).

I have the following XAML:

<tel:RadListBox ItemsSource="{Binding Path=DtedDirectories}"

SelectedValue="{Binding Path=SelectedDtedDirectory}"

SelectionMode="Single">

<tel:RadListBox.ItemContainerStyle>

<Style TargetType="tel:RadListBoxItem">

<Setter Property="tel:DragDropManager.AllowCapturedDrag" Value="True" />

</Style>

</tel:RadListBox.ItemContainerStyle>

<tel:RadListBox.DragDropBehavior>

<tel:ListBoxDragDropBehavior AllowReorder="True" />

</tel:RadListBox.DragDropBehavior>

</tel:RadListBox>

The problem I have is that the list box will let me drop items outside of it, thus removing the item from the list. I do not want this behavior.

[Solved] Moving objects pans the map

I may be going about this the wrong way, but here's what I am doing. I have a polygon (or whatever). I want to click a vertex point, drag it, and have the polygon updated. I do this by creating a MapPinPoint for each vertex. In the MouseLeftButtonDown event for this point, I set the MouseDragMode to None. In the Map_MouseLeftButtonUp event, I set the MouseDragMode back to Drag. The problem is when I do this, the map sometimes does a pan operation based on where I originally clicked down and where I lifted up. How can I prevent this, or is there a better way to do it?

RadExpander.IsExpanded Binding

I've just switched to telerik and are replacing my elements.

My problem is that the normal expander works and the telerik doesnt.. I've placed them next to each other in the code, to validate this.

    
            <Expander IsExpanded="{Binding Path=IsExpanded}"></Expander> 
        
            <Telerik:RadExpander IsExpanded="{Binding Path=IsExpanded}" ></Telerik:RadExpander>

Bound to

    
            private bool _isExpanded = true;  
        
            public bool IsExpanded  
        
            {  
        
               get { return _isExpanded; }  
        
               set 
        
               {  
        
                   _isExpanded = value;  
        
                   //Some code  
        
               }  
        
            }

Is this the wrong way to do it?

[Solved] RadDiagram Layout() & AutoFit() - when is the proper moment to use it?

I'm adding shapes and connections manually in code behind to my RadDiagram. I'd like RadDiagram to layout shapes and fit it after adding last item, so i call RadDiagram.Layout(); and RadDiagram.AutoFit(); but that does not work. Why?

private void Button_Click_1(object sender, RoutedEventArgs e)

{

var shapes = new List<RadDiagramShape>();

for (int i = 0; i <= 15; i++)

{

var shape = new RadDiagramShape();

shapes.Add(shape);

if (i == 0)

{

_mainShape = shapes[0];

}

if (i > 0)

{

var conn = new RadDiagramConnection {Source = _mainShape, Target = shape, SourceCapType = CapType.Arrow1};

RadDiagram.Items.Add(conn);

}

RadDiagram.Items.AddRange(shapes);

RadDiagram.Layout();

RadDiagram.AutoFit();

}

[Solved] Insert space issue

Hi,
I'm using the newly released version (2013.3.1016.40) of RadMaskedTextInput control.
The control has a strange behavior when inserting space.

<telerik:RadMaskedTextInput Culture="" Mask="" MinWidth="300" Margin="10,10,10,10"

HorizontalContentAlignment="Right"

UpdateValueEvent="LostFocus" TextMode="PlainText" InputBehavior="Insert" />

1. Type 1234567.
2. Put the cursor between 1 and 2.
3. Type space.
The input becomes "12 34567".

My environment: VS 2010, Windows 7.

Regards,
Gong

[Solved] Get DoubleClicked Cell and its Data Coordinates

Hi all,
Is there a way to get the clicked cell (double click) with 2013-3 version?
In the previous versions and internal builds (since one or two month ago) I was able to get clicked cell with this code:

private void pivot_MouseDown(object sender, MouseButtonEventArgs e)

{

if (e.ClickCount == 2)

{

RadPivotGrid p = sender as RadPivotGrid;

FrameworkElement cell = e.OriginalSource as FrameworkElement;

then with cell object I was able to read properties such MDX coordinates to open for example a drill down data window.

Now if I try this code the cell variable is null. How can I get clicked cell and then MDX coordinates? Is it possible?

Many thanks in advance!

Best Regards,
Davide

RadRibbonWindow Title Bar Issue with Win8 and VS2012RC

Hi,

I'm using Telerik RadControls for WPF Q2 2012 within Visual Studio 2012 RC. Generally, I've no problems, except with the RadRibbonWindow, which displays a light blue bar over the entire Title Bar area, effectively covering up the three buttons on the upper right hand side (see attached image). The problem appears to be similar to that found in the post "trying to run existing application with RadRibbonWindow in Win8... Aero2 error" within this same forum.

In that post (dated 07/12/2012), Viktor (from Telerik) replies that an internal build will be available in a week (approx. 07/19/2012). However, I find no internal build that addresses this issue. To be specific, my version of Telerik.Windows.Controls.RibbonView is 2012.2.607.40 and the runtime version is v4.0.30319.

I'm replacing the standard WPF MainWindow XAML file Window control with a Telerik RadRibbonWindow and set "RadRibbonWindow.IsWindowsThemeEnabled = false;" in the static constructor of MainWindow. I'd appreciate any direction or fix you can provide.

Thanks,

Chris A
