Hello, 

I have this combobox with is bound to List of customers around 5k customers

I changed to virtualization and this helped in getting the list faster but when I added SelectedValue to bind to my viewmodel It is getting very very slow to load.

Is there any way to overcome this problem ?

Regards

Using the RangeBarSeries with data points that overlap another series, the tooltip for the covered up data point is shown rather than the one on top.

However the "hover" clearly knows which is the series being hovered over. See attached screenshots. chart1.pg shows the longest (yellow) bar being hovered over. chart2.png shows the adjacent orange series and chart3 shows the green series. All 3 have the same tooltip, of the longest series which runs underneath the others.

How can I fix this and get the tooltips to show for the proper data point?

Does the RadGridView have something similar to the SelectedItemsSource that the RadListbox has? I'd like to automatically bind the selected items to a collection in my view-model like I do with the list box.

example:

<telerik:RadGridView
     ItemsSource="{Binding ..., Mode=OneWay}"
     telerik:ListBoxSelectedItemsBehavior.SelectedItemsSource="{Binding ..., Mode=OneWay}">

I am trying to set the default visual style of my line series. (Using Telerik UI for WPF 2015)

Based on the page, the default visual style of the dot & line styling can be set at the default visualstyle properties:

https://docs.telerik.com/devtools/wpf/controls/radchartview/styles-and-templates/customizing-cartesianchart-series

This configuration does not seems to work on Telerik UI for WPF 2015, how do I set the dot size & coloring on line series ? 

I have two series, and I want to display them in a same graph. 

The series 1 has valued at {0.5: value1, 1.5 : value2, 2.5 : value3}

And series 2 has value at { 1: value 1, 2 value2: 3 value3} 

How do I draw the two series on the same graph with X value being interlaced ? Tried linear axis but nothing displayed, tried catagroy axis but the graph is separated into two parts. The x value is not interlacing. 

I have an application where I want to write tests to confirm the content of a ToolTip. If the ToolTip is simple text, all is fine, the checks in Step Builder work as expected.

If I add other elements e.g.

            <Polygon 
                        Points="16, 32 32, 32 24, 18"
                        Visibility="Visible"
                        ToolTipService.ShowDuration="360000" HorizontalAlignment="Right" Width="32">
                <Polygon.Fill>
                    <SolidColorBrush Color="Aqua"/>
                </Polygon.Fill>
                <Polygon.ToolTip>
                <StackPanel>
                    <TextBlock Text="Foo"/>
                    <Ellipse Width="20" Height="20" Fill="Pink"/>
                    <TextBlock Text="Bar"/>
                </StackPanel> 
            </Polygon.ToolTip>
            </Polygon>
What I see in the Visual Tree is a ToolTip "FooBar". How can I do a test on, say, the colour of the ellipse?

If my ToolTip is made of Runs e.g.

                    <TextBlock>
                        <Run Text="Foo"/>
                        <Run Text="Bar"/>
                    </TextBlock>

Then in the Visual Tree, the ToolTip is blank and any steps created in Step Builder to determine the content will fail.

If the tooltip is made up from WPF elements, how can these be accessed, either via Step Builder, or via a coded step?

I'm evaluating to use ChartView3D to visualise the path of a drill hole, that starts at the surface and goes into the ground. To achieve this I rotated the whole graph 180 degrees but then all labels and axis titles also rotates :( See screendump.

Is there any way to only rotate the graph? Or counter-rotate the labels and titles? Or any other way to achieve this?

I already set PasswordBox properties:
