Hi

i have a treeview control in a wpf form

the user wants to jump and select an item when he presses any letter on the keyboard

so i did just that with the treeView_TextInput event and on capturing text i found the desired item and selected it like this:

treeView.SelectedItem = found;
treeView.BringItemIntoView(found);
treeView.BringIntoView();​

My problem is that after the item is selected, the keyboard navigation will not work from the newly selected item.

as a matter of fact, the navigation will move from the previously selected item that the user selected with the mouse and not from the one the code selected

is that a bug?

thank you

Hello,

I'm trying to create a custom SelectionMiniToolbar but I am encountering several issues.

I've tried some examples found here but I still have problems.

First of all I'm unable to remove the Title Bar from the RadRichTextBoxWindow and also I'm unable to position correctly the Window to appear where the default SelectionMiniToolbar would appear.

I would really like to have an example that shows how to declare a custom SelectionMiniToolbar and how to position it correctly as the default toolbar does.

Right now all the code that I have is:

RichTextBoxFormatToolbar.xaml 

01.<richTextBoxUI:RadRichTextBoxWindow x:Class="Views.RichTextBoxFormatToolbar"
03.             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
04.             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
05.             xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
06.             xmlns:richTextBoxUI="clr-namespace:Telerik.Windows.Controls.RichTextBoxUI.Dialogs;assembly=Telerik.Windows.Controls.RichTextBoxUI"
07.             ResizeMode="NoResize" WindowStartupLocation="CenterOwner">
08. 
09.    <StackPanel Orientation="Horizontal">
10. 
11.        <Button>Test</Button>
12.         
13.    </StackPanel>
14.     
15.</richTextBoxUI:RadRichTextBoxWindow>

RichTextBoxFormatToolbar.xaml.cs

01.[CustomSelectionMiniToolBar]
02.  public partial class RichTextBoxFormatToolbar : RadRichTextBoxWindow, ISelectionMiniToolBar
03.  {
04.      public RichTextBoxFormatToolbar()
05.          : base()
06.      {
07.          InitializeComponent();
08.      }
09. 
10.      public void Hide()
11.      {
12.          Owner = null;
13.          Close();
14.      }
15. 
16.      public void SetOpacity(double opacity)
17.      {
18.          Opacity = opacity;
19.      }
20. 
21.      public void Show(Point location, RadRichTextBox radRichTextBox)
22.      {
23.          SetOwner(radRichTextBox);
24.          Show();
25.      }
26.  }

 

Thanks a lot for the help

Hi,

 

I have a RadDateTimePicker which is databound to a class object when my form loads I want to display and empty value in order that the watermark content is displayed. I also want to display a date range when the date time picker is selected and in order to do this I am setting the display range values when the main window is loaded. My problem is that I am seeing the default null value  01/01/0001 00:00:00!  How do I achieve this behavior 

 

<telerik:RadDateTimePicker x:Name="DeldateTime" Width="160" TimeInterval="0:30:0" DateTimeWatermarkContent="Delivery Date\Time" SelectedValue="{Binding dtDeliverDate, Mode=TwoWay, NotifyOnValidationError=True, ValidatesOnDataErrors=True}" Height="26" VerticalAlignment="Bottom" ToolTip="Delivery date - Select both Day and Time values!" TabIndex="4" IsTabStop="True"  />

Date range set on loaded event

Me.DeldateTime.SelectableDateStart = DateTime.Now.AddMonths(-3)
Me.DeldateTime.SelectableDateEnd = DateTime.Now.AddMonths(3)
Me.DeldateTime.DisplayDate = DateTime.Now

Property

Public Property dtDeliverDate() As DateTime
        Get
            Return Me.m_dtDeliverDate
        End Get
        Set(value As DateTime)
            Me.m_dtDeliverDate = value
            If IsDate(m_dtDeliverDate) Then
                Me.m_szDeliveryTime = Format(m_dtDeliverDate, "HH:mm")
            End If
            Me.SendPropertyChanged("dtDeliverDate")
        End Set
    End Property​

Hello Telerik

 

A double click on any node, edge, or text content of my Diagram display the underlying object type (c.f. attached image)

I succeeded to prevent this for the nodes, adding the following property to the Diagram in XAML:

ShapeDoubleClicked="diagram_ShapeDoubleClicked"

And in code-behind:

private void diagram_ShapeDoubleClicked(object sender, Telerik.Windows.Controls.Diagrams.ShapeRoutedEventArgs e)
      {
         e.Handled = true;
      }

However I would like to disable this behavior for anything on the Diagram.

I did try the same idea with the MouseDoubleClick event, but it didn't change anything: edges and texts still displays object types...

Is there a solution to this?

Thanks for your help,

Sylvain

How would I go about enabling the tool tip for a slot in the RadScheduleView. I already have a tool tip defined for the appointment, but I need to provide the user with additional information about each slot when they are trying to decide where to make their appointment.

Thank you in advance,

Hi,

I have a rad grid view in my application and I like the power of the column filtering.

My xaml looks like this:

<telerik:RadGridView AutoGenerateColumns="False" ItemsSource="{Binding Entries}" IsReadOnly="True" CanUserReorderColumns="False" CanUserDeleteRows="False" CanUserInsertRows="False" RowDetailsVisibilityMode="Visible" SelectionMode="Extended">
    <telerik:RadGridView.Columns>
        <telerik:GridViewDataColumn DataMemberBinding="{Binding Name}" Header="Name" IsReadOnly="True"/>
        <telerik:GridViewDataColumn DataMemberBinding="{Binding Connections}" Header="Connections" IsReadOnly="True"/>
    </telerik:RadGridView.Columns>
</telerik:RadGridView>

The gridview binds its itemssource to an observable collection. 

When someone is filtering on the connections column and one of the items connection property changes, the filtered content is not updated. The updated value does appear in the column however (thanks to INotifyPropertyChanged). I noticed that when the collection changes the filter does work. Is there a way to trigger a filter update as well when a property like connections is updated?

Kind regards

Hi,

I must use a SecureString as a property type. Is it possible to edit the value in the PropertyGrid? How can I achieve this?

I already tried to get the value in the EditEnded event and tried to convert it on my own, but I do not get the value, it is null.

Thanks for your replies.

I was wondering how to style dynamically-created clustered/stacked bar charts (created using ChartSeriesProvider), so that there is a border around each bar (i.e., be able to set BorderBrush and BorderThickness properties).  Here is a code snipped of the *.xaml without borders.

<telerik:RadCartesianChart.SeriesProvider>
               <telerik:ChartSeriesProvider Source="{Binding Data}">
                   <telerik:ChartSeriesProvider.SeriesDescriptors>
                       <telerik:CategoricalSeriesDescriptor ItemsSourcePath="Data" ValuePath="Sales" CategoryPath="Article">
                           <telerik:CategoricalSeriesDescriptor.Style>
                               <Style TargetType="telerik:BarSeries">
                                   <Setter Property="CombineMode" Value="Stack" />
                                   <Setter Property="local:ChartUtilities.SeriesStackGroupKey" Value="{Binding StackGroup}" />
                                   <Setter Property="LegendSettings">
                                       <Setter.Value>
                                           <telerik:SeriesLegendSettings Title="{Binding NameInLegend}"/>
                                       </Setter.Value>
                                   </Setter>
                               </Style>
                           </telerik:CategoricalSeriesDescriptor.Style>
                       </telerik:CategoricalSeriesDescriptor>
                   </telerik:ChartSeriesProvider.SeriesDescriptors>
               </telerik:ChartSeriesProvider>


Thanks!

Hi,

 I insert a table to a RichTextBox and formatting it with both built-in UI and programmatically as http://docs.telerik.com/devtools/wpf/controls/radrichtextbox/document-elements/features-tables.html#formatting-a-table-via-the-built-in-ui . However when I'm adjusting the height of table row, by programmatically it can be shorter than the default size when font size is 8 and by cursor the min height is the default height when the table is created. Is there anyway to make the mouse drag the row height smaller then that?

Thanks,

Yiping
