[Solved] RodPivotMap doesn't show custom tooltip

[Alex]

Hi,

I have a simple RadPivotMap, latest build, defined like this:

<telerik:RadPivotMap x:Name="RadTreeMap" LayoutStrategy="Squarified"
     ItemsSource="{Binding CountryData}"
     LabelPath="Country" ValuePath="CountryAmount"
     ToolTipPath="CountryAmount" ToolTipFormat="{}{0:N0} i/day}">
 <telerik:RadPivotMap.GroupDefinitions>
  <telerik:GroupDefinition Member="Continent">
  </telerik:GroupDefinition>
 </telerik:RadPivotMap.GroupDefinitions>

</telerik:RadPivotMap>

 

Data from ViewModel is simple too:

public IEnumerable<CountryItem> CountryData // ... regular MVVM property
public class CountryItem
{
 [Key]
 public int ID { get; set; }
 public string Continent { get; set; }
 public string Country { get; set; }
 public string CountryAmount { get; set; }
}

 
Using MS DomainContext/DomainDataSource to load data from DB:

_domainDataSource.LoadedData += (_o, _e) =>
 {
   List<CountryItem> list = new List<CountryItem>();

   foreach (vwCountry v in _e.Entities)
   {
    list.Add(new CountryItem()
    {
     ID = v.ID,
     Region = v.Region,
     Country = v.Country,
       CountryAmount = v.Amount,
    });
   }

   this.CountryData = list.AsEnumerable();
  }
 };

  

Now I want to get ToolTip on RadPivotMap's items. If I do it like in Telerik samples

 

<controls:ChildWindow.Resources>
    <DataTemplate x:Key="tooltTipTemplate">
    ...
    </DataTemplate>
</controls:ChildWindow.Resources>

then I get 2 exceptions for each CountryData item:
 System.Windows.Data Error: Cannot get 'ToolTip' value (type 'System.Object') from 'TreeMapData Value: 145170; ChildrenCount: 0; Depth: 1' (type 'Telerik.Windows.Controls.TreeMap.GroupData'). BindingExpression: Path='ToolTip' DataItem='TreeMapData Value: 145170; ChildrenCount: 0; Depth: 1' (HashCode=27707615); target element is 'Telerik.Windows.Controls.TreeMap.RadTreeMapItem' (Name=''); target property is 'ToolTipContent' (type 'System.Object').. System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.FormatException: Input string was not in a correct format.
 System.Windows.Data Error: Cannot get 'ToolTipAvailable' value (type 'System.Boolean') from 'TreeMapData Value: 145170; ChildrenCount: 0; Depth: 1' (type 'Telerik.Windows.Controls.TreeMap.GroupData'). BindingExpression: Path='ToolTipAvailable' DataItem='TreeMapData Value: 145170; ChildrenCount: 0; Depth: 1' (HashCode=27707615); target element is 'Telerik.Windows.Controls.TreeMap.RadTreeMapItem' (Name=''); target property is 'IsEnabled' (type 'System.Boolean').. System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.FormatException: Input string was not in a correct format.

 
And if I try to set template inside RadPivotMap -

<telerik:RadPivotMap.ToolTipTemplate>
    <DataTemplate>
        ...
    </DataTemplate>
</telerik:RadPivotMap.ToolTipTemplate>

 

I get nothing at all - no exceptions, no tooltip
     
What am I doing wrong?

TIA

Hi Alex,

This example shows tooltips on pivotmap in action. The template is defined in the resources and is then set to the pivotmap using a StaticResource markup extension. Please note, that currently only leaves have tooltips.

All the best,
