Hi Zeljko Lazic, 

 

Greetings from Syncfusion. 

 

We have analyzed your query and we have achieved your requirement by using the below code snippet. 

 

#Solution 1 : Binding directly to CheckBox IsChecked property 

<CheckBox x:Name="checkBox" IsChecked="{Binding ShowToolbar}">Turn on zoom toolbar</CheckBox> 

 

<syncfusion:SfChart Grid.Row="1"> 

    <syncfusion:SfChart.Behaviors> 

        <syncfusion:ChartZoomPanBehavior EnableZoomingToolBar="{Binding Path=IsChecked, Mode=TwoWay, Source={x:Reference checkBox}}"> 

        </syncfusion:ChartZoomPanBehavior> 

    </syncfusion:SfChart.Behaviors> 

</syncfusion:SfChart> 

 

#Solution 2:  Binding ViewModel property via Checkbox DataContext 

<CheckBox x:Name="checkBox" IsChecked="{Binding ShowToolbar}">Turn on zoom toolbar</CheckBox> 

 

<syncfusion:SfChart Grid.Row="1"> 

    <syncfusion:SfChart.Behaviors> 

        <syncfusion:ChartZoomPanBehavior EnableZoomingToolBar="{Binding Path=DataContext.ShowToolbar, Mode=TwoWay, Source={x:Reference checkBox}}"> 

        </syncfusion:ChartZoomPanBehavior> 

    </syncfusion:SfChart.Behaviors> 

</syncfusion:SfChart>
