FrameworkElementFactory.AddHandler not working

I am using a RadPropertyGrid. I am trying to use the AutoGeneratingPropertyDefinition event to provide a custom EditorTemplate with a textbox. I want to add a handler to the TextChanged event of the textbox but my event handler is never being called.

Relevant code:

public void GeneratingProperty(AutoGeneratingPropertyDefinitionEventArgs e)

{

try

{

AvailableProperties property = (AvailableProperties)Enum.Parse(typeof(AvailableProperties), e.PropertyDefinition.Binding.Path.Path);

if (IsAvailable(item.GetAvailableProperties(), property))

{

switch (property)

{

case AvailableProperties.Title:

FrameworkElementFactory textBoxFactory = new FrameworkElementFactory(typeof(TextBox));

textBoxFactory.AddHandler(TextBox.TextChangedEvent, new TextChangedEventHandler(TitleTextChanged));

textBoxFactory.SetValue(TextBox.BackgroundProperty, System.Windows.Media.Brushes.Tomato);

textBoxFactory.SetValue(TextBox.BorderBrushProperty, System.Windows.Media.Brushes.Transparent);

textBoxFactory.SetBinding(TextBox.TextProperty, new Binding("Title"));

DataTemplate template = new DataTemplate();

template.VisualTree = textBoxFactory;

template.Seal();

e.PropertyDefinition.EditorTemplate = template;

e.PropertyDefinition.OrderIndex = 0;

e.PropertyDefinition.DisplayName = "Title";

e.PropertyDefinition.Description = "The title of the attribute. Can only contain letters, numbers, and underscores.";

break;

default:

// other properties go in case statements above here

break;

}

else

{

e.Cancel = true;

}

catch

{

e.Cancel = true;

}

public void TitleTextChanged(object sender, TextChangedEventArgs e)

{

if (sender is TextBox)

{

TextBox titleTextBox = (TextBox)sender;

int caretIndex = titleTextBox.CaretIndex;

string newValue = titleTextBox.Text;

item.Title = newValue;

ApplyCorrectedValue(newValue, item.Title, titleTextBox, caretIndex);

NotifyOfPropertyChange(() => MappingsPanel);

}

else

{

Logger.Log("TitleChanged: source must be a TextBox");

throw new ArgumentException("source must be a TextBox");

}

I am using the 2012.2.912.35 version of the telerik dlls

Calling a UDF for populating a RadGridView, fails

Hi ya, I'm trying to populate one RadGridView using an UDF Sql Server which waits a parameter but it doesn't work:

XAML:

<telerik:RadGridView x:Name="dgvHistoricoOR" HorizontalAlignment="Left" FontFamily="Segoe UI"

FontSize="12" FontStyle="Normal"

Margin="10,44,-185,0" VerticalAlignment="Top" Height="175" Width="437"

ColumnWidth="SizeToCells" Grid.ColumnSpan="2" Grid.RowSpan="2">

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn DataMemberBinding="{Binding ord_repalpha}" Header="{Resx RadGridViewOr_Or}"

Width="40"/>

<telerik:GridViewDataColumn DataMemberBinding="{Binding F_Alta}" Header="{Resx RadGridViewOr_Alta}"

Width="60"/>

<telerik:GridViewDataColumn DataMemberBinding="{Binding F_Cierre}" Header="{Resx RadGridViewOr_Cierre}"

Width="60"/>

</telerik:RadGridView.Columns>

Code-behind:

ada = New SqlDataAdapter("SELECT * FROM OR_Historico_Por_Cliente(@par1)", aBD.connection)

ada.SelectCommand.Parameters.AddWithValue("@par1", Documento)

ada.Fill(ds, "OR_Historico_Por_Cliente")

Me.dgvHistoricoOR.ItemsSource = "OR_Historico_Por_Cliente"

Me.dgvHistoricoOR.DataContext = ds

OR_Historico_Por_Cliente('') UDF Sql2k8 returns a TABLE

I don't get data, my Grid remains empty

I wonder, when I call Fill method, should I include the value for the parameter???

Help!

RadListBox drag and drop wierd behaviour

I'm working on a screen with WPF which has 3 listbox (list1, list2, list3), and i can drag items from list1 to list2 and list2 to list3 or even list1 to list3, and i can do it reversely.

I had to change the listbox (list3) to radListBox, because i wanted to implement the reorder within this list, i managed that drag and drop worked, and it did. but when a i wanted to drag an item from list3 (radlistbox), i got null in this variable :
" var data = ((DataObject)args.Data).GetData("DragData") as UcFileColumn", which UcFileColumn is a user control that i wanna cast with to drop in other lists. So insted od using "data" i thought using then selectedItem property to take the item dragged, and it works. Still one mysterious behaviour occured, is that when i dropped items in the lists3 (radListBox) and then drag them back into the lists(list1 or list2), and i wanted to dropped them back, the list prevent me to drop, i think when i remove item from teh radlistbox, the allowdrag dosent set anymore !!!!, is that because i used SelectedItem, if yes how should i get the element dragged from (DataObject)args.Data).GetData..

here is my XAML CODE :

<UserControl.Resources>

<Style x:Key="DraggableListBoxItem" TargetType="controls4:RadListBoxItem">

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

<Setter Property="dragDrop:DragDropManager.AllowDrag" Value="True" />

</Style>

</UserControl.Resources>

<ListBox Grid.Row="2" x:Name="List1" ItemsSource="{Binding Source1, Mode=TwoWay}" AllowDrop="True" IsSynchronizedWithCurrentItem="True"

Style="{StaticResource ListBoxStyleMenu}" Margin="2,2,2,2"

VerticalAlignment="Stretch" HorizontalContentAlignment="Center" HorizontalAlignment="Stretch">

<ListBox.ItemsPanel>

<ItemsPanelTemplate>

<UniformGrid Columns="2" />

</ItemsPanelTemplate>

</ListBox.ItemsPanel>

<ListBox.ItemContainerStyle>

<Style TargetType="{x:Type ListBoxItem}">

<Setter Property="Focusable" Value="False"/>

<Setter Property="Margin" Value="0,5,0,5" />

</Style>

</ListBox.ItemContainerStyle>

</ListBox>

<ListBox Grid.Row="2" x:Name="List2" ItemsSource="{Binding Source2, Mode=TwoWay}" AllowDrop="True" IsSynchronizedWithCurrentItem="True"

Style="{StaticResource ListBoxStyleMenu}" Margin="2,2,2,2"

VerticalAlignment="Stretch" HorizontalContentAlignment="Center" HorizontalAlignment="Stretch">

<ListBox.ItemsPanel>

<ItemsPanelTemplate>

<UniformGrid Columns="2" />

</ItemsPanelTemplate>

</ListBox.ItemsPanel>

<ListBox.ItemContainerStyle>

<Style TargetType="{x:Type ListBoxItem}">

<Setter Property="Focusable" Value="False"/>

<Setter Property="Margin" Value="0,5,0,5" />

</Style>

</ListBox.ItemContainerStyle>

</ListBox>

<controls4:RadListBox x:Name="List3" ItemsSource="{Binding Source3}" AllowDrop="False" SelectedItem="{Binding SourceSelected, Mode=TwoWay}"

VerticalAlignment="Stretch" HorizontalContentAlignment="Center" HorizontalAlignment="Stretch"

Margin="2,2,2,2" ItemContainerStyle="{StaticResource DraggableListBoxItem}">

<controls4:RadListBox.DragDropBehavior>

<behaviors:ListBoxDragDropBehavior AllowReorder="True" dragDrop:DragDropManager.TouchDragTrigger="TapAndHold" />

</controls4:RadListBox.DragDropBehavior>

</controls4:RadListBox>

I'm looking forward for your response

[Solved] Numbered list font style

Hello!

I'm having an issue when applying a font style to a numbered list in RadRiсhTextBox.

Steps to reproduce:
1. Create some lines of text
2. Select all of newly created lines of text.
3. Apply numbered list to these lines of text.
4. Set a font different from the default one

The numbrer indicator of the last line won't apply a new font.
The screenshot is attached to this post.

This can be reproduced even in your latest demo.

Thanks in advance.

Mixing Right-To-Left and Left-To-Right Text

It appears as though the WPF RichTextBox doesn't play well with mixing LTR and RTL characters in the same string.

Pasting the following string into the TextBox gives mixed results including displaying question marks, flipping brackets and changing the position of neutral characers. The issue seems to persist even when putting an LRM character in front of the bracket, as seen in this article: http://www.iamcal.com/understanding-bidirectional-text/.

[KEY]="مرحبا العالم"

Pasting the same text into (for example) Notepad++ displays the text just fine. Is this a known issue, and are there any plans to support this?

Thanks,
Tom

Scaling Coordinates for positioning of items on Rad Diagram

I have the the following requirements, that I'm unsure as to how to implement with the Rad Diagram control:

Our business objects all have geographical coordinates associated with them. The objects should be displayed as items on a diagram with the diagram positioning being representative of their geographical coordinates (Note The coordinate system in use is Northing / Easting). These coordinates should be two-way (i.e. the user should be able to drag the object to a new position and this should reflected in our object model).

Thus far I'm having difficulty understanding the following:

1) How to apply a 2 way scaling between the RadDiagram node's Point position and the business objects geographical Coordinates. The scaling should take into consideration the available space in the RadDiagram and the series of coordinates being plotted.
2) Have the business object's geographical coordinates display in the InformationAdorner i.e. whenever the object is being dragged the adorner should display the coordinates and not the X & Y of the Point.
3) How to flip the Y axis of the diagram (perhaps this is to be done in the scaling?)

I've looked thru' all the examples on the RadDiagram, but none seem appropriate for the above requirements. Any tips would be appreciated?

Gary.
