Hi,

I implemented some custom connections, deriving them from RadDiagramConnection. My connections have their own properties and visual aspect (defined using styles). I'd like to use the Telerik connection tool to draw my custom connection: how can i set the custom connection type to the connection tool?

Thank you in advance

Hey,

I have RadTreeListView named ItemsTree and i have another RadTreeListView named ChildItemsTree, the ChildItemsTree is inside the RowDetailsTemplate of ItemsTree, when the user selects an item from the ChildItemsTree i noticed that the selected item of ItemsTree does not clear. what i want to do is to clear the selected items of ItemsTree when the user selects an item from the ChildItemsTree​ and vice versa.

Thanks in advance.

 Hello,

I was wondering if there was any new option in the control to modify at once several cells of a GridViewComboBoxColumn, as I am using the same ItemsSourceBinding for all rows of that column (in my GridView, the selection ​is: SelectionMode="Multiple" SelectionUnit="FullRow").

I found that as a string point, but is there some other builtin/custom option than that kind:

Hi, 

 I try to customize the appointment of a scheduleview. I use the following code to change the backgroud color. But I also need to change the background color when the appointment is selected. How can we change it ?

        <scheduleview:OrientedAppointmentItemStyleSelector x:Key="AppointmentItemStyleSelector">
            <scheduleview:OrientedAppointmentItemStyleSelector.VerticalStyle>
                <Style TargetType="scheduleview:AppointmentItem" BasedOn="{StaticResource AppointmentItemBaseStyle}">
                    <Setter Property="Background" Value="#C1D72E" />
                </Style>
            </scheduleview:OrientedAppointmentItemStyleSelector.VerticalStyle>
        </scheduleview:OrientedAppointmentItemStyleSelector>

Thanks

Hello,

When plotting a StepLineSeries onto a CategoricalAxis chart with only one single category we don't get the 'step' rendered for that value.

Is there a way to get this single value to show? Or is there another way to plot a straight line across the full width of a category at a specific value?

Thanks in advance for any help you can provide.
