TreeMap not resizing after timer Tick event

[Gustavo]

After Timer Tick event the value in the ToolTip is updated but the size and the color don't.

Hello Gustavo,

Thank you for the attached code snippets and explanations. I was able to quickly create a new project and reproduce the problematic behavior.

I can confirm that this is a bug in the control. I have logged it here where you can vote and track its status, we will do our best to fix this for the upcoming SP release. I have also updated your Telerik points as a thank you for taking out of your time and helping us improve our products.

The bug is essentially an incorrect if-else clause. You can work around it by creating a new Gdp2 property to set the TooltipPath, so that the TooltipPath, ValuePath and LabelPath properties use different property names:

<telerik:TypeDefinition TargetTypeName="GdpInfo"
  ValuePath="Gdp"
  ToolTipPath="Gdp2" />

Hi Petar, thanks for help me.
This work around works for the scenario where the size was not updating.
But the color of an item still not updated when changing the value.

<telerik:RadTreeMap Name="xTreeMap" LayoutStrategy="Squarified" BorderThickness="1" BorderBrush="Black" ItemsSource="{Binding DataTags}">
      <telerik:RadTreeMap.TypeDefinitions>
        <telerik:TypeDefinition TargetTypeName="GdpInfo"
                                ValuePath="GdpValue"
                                LabelPath="Country"
                                ToolTipPath="GdpToolTip"
                                ToolTipFormat="{}{0:C0} Mln">
          <telerik:TypeDefinition.Mappings>
            <telerik:ValueBrushColorizer IsAbsolute="True"
                                 ValuePath="GdpColor"
                                 RangeMinimum="0"
                                 RangeMaximum="2000"
                                 Brushes="{StaticResource ColorizerBrushes}" />
          </telerik:TypeDefinition.Mappings>
        </telerik:TypeDefinition>
      </telerik:RadTreeMap.TypeDefinitions>
    </telerik:RadTreeMap>

Hello Gustavo,

Thank you for the additional information! Indeed the color does not get updated either. I have logged this as a separate bug here. Again we have awarded you some Telerik points as a small token of gratitude.
