Hi!, I have a question.

When I edit a text from Node, the text is removed and I cant add again the text, this is the code of this:

  <DataTemplate x:Name="NodeTemplate" x:Key="NodeTemplate">
  	<go:SpotPanel 
  		Name="SpotPanel"
  		go:Part.SelectionAdornmentTemplate="{StaticResource NodeSelectionAdornmentTemplate}" 
  		MouseLeftButtonDown="Node_MouseLeftButtonDown"
  		MouseLeftButtonUp="Node_MouseLeftButtonUP"
  		go:Part.SelectionAdorned="True" 
  		go:Node.Location="{Binding Data.Location, Mode=TwoWay}" Background="White">
  		<go:NodePanel Sizing="Auto" go:SpotPanel.Main="True">
  			<Grid Name="grillaNodo" VerticalAlignment="Center" HorizontalAlignment="Center">
  				<Grid.RowDefinitions>
  					<RowDefinition />
  					<RowDefinition />
  				</Grid.RowDefinitions>
  				<TextBlock 
  					Grid.Row="0" 
  					Text="{Binding Data.Icono}" 
  					Name="Icono_Nodo" 
  					HorizontalAlignment="Center" 
  					FontFamily="Fonts\SegoeUiSymbol.ttf#Segoe UI Symbol"
  					Foreground="{Binding Data.ColorIcono, Mode=TwoWay, Converter= {StaticResource converterColor}}" 
  					FontSize="{Binding Data.TamanioFuenteIcono, Mode=TwoWay}" />
  				<TextBlock Name="TextoNodos" 
  						   Grid.Row="1" 
  						   Text="{Binding Data.Text, Mode=TwoWay}" 
  						   Foreground="{Binding Data.ColorTexto, Mode=TwoWay, Converter= {StaticResource converterColor}}" 
  						   FontSize="{Binding Data.TamanioFuenteTexto, Mode=TwoWay}" 
  						   FontFamily="{Binding Data.TipoFuenteTexto, Mode=TwoWay}" 
  						   go:Part.TextEditable="True" LostFocus="TextoNodos_LostFocus" HorizontalAlignment="Center" />
  			</Grid>
  		</go:NodePanel>
  		<Rectangle Fill="Transparent" Width="6" Height="6" go:SpotPanel.Spot="MiddleLeft" 
  				   go:SpotPanel.Alignment="MiddleLeft" 
  				   go:Node.PortId="L" 
  				   go:Node.LinkableFrom="True" 
  				   go:Node.LinkableTo="True" 
  				   Cursor="Hand" 
  				   go:Node.FromSpot="MiddleLeft" 
  				   go:Node.ToSpot="MiddleLeft" />
  		<Rectangle Fill="Transparent" Width="6" Height="6" go:SpotPanel.Spot="MiddleTop" 
  				   go:SpotPanel.Alignment="MiddleTop" 
  				   go:Node.PortId="T"
  				   go:Node.LinkableFrom="True" 
  				   go:Node.LinkableTo="True" 
  				   Cursor="Hand" 
  				   go:Node.FromSpot="MiddleTop" 
  				   go:Node.ToSpot="MiddleTop" />
  		<Rectangle Fill="Transparent" Width="6" Height="6" go:SpotPanel.Spot="MiddleRight" 
  				   go:SpotPanel.Alignment="MiddleRight" 
  				   go:Node.PortId="R"
  				   go:Node.LinkableFrom="True"
  				   go:Node.LinkableTo="True"
  				   Cursor="Hand" 
  				   go:Node.FromSpot="MiddleRight"
  				   go:Node.ToSpot="MiddleRight" />
  		<Rectangle Fill="Transparent" Width="6" Height="6" go:SpotPanel.Spot="MiddleBottom"
  				   go:SpotPanel.Alignment="MiddleBottom"
  				   go:Node.PortId="B"
  				   go:Node.LinkableFrom="True"
  				   go:Node.LinkableTo="True"
  				   Cursor="Hand" go:Node.FromSpot="MiddleBottom"
  				   go:Node.ToSpot="MiddleBottom" />
  	</go:SpotPanel>
  </DataTemplate>

When the TextBlock’s string is empty, that FrameworkElement/UIElement is fairly narrow, although it has a positive width. So that makes it harder to click on in order to start editing again.

Another way to start editing (regardless of the string to be edited) is to select the node and hit the F2 key.

Another solution is to impose a minimum size on the TextBlock.
