How can I Show Trackball for each series?

For i = 0 To Me.RadListView1.Items.Count - 1
                If RadListView1.Items(i).CheckState = Telerik.WinControls.Enumerations.ToggleState.On Then
                   Dim lii As Integer = RadListView1.Items(i).Value
                    Dim liText As String = RadListView1.Items(i).Text
                    ''SingleHistory = MeasureWS.SingleHistory(lii.ToString, TextBoxStart.Text, TextBoxEnd.Text, "120")
                    SingleHistory = MeasureWS.SingleHistory(lii.ToString, "", TextBoxStart.Text, TextBoxEnd.Text, "120")

                    Dim LineSeriesY As New LineSeries()
                    LineSeriesY.LegendTitle = liText
                    'LineSeriesY.Name = liText
                    Dim LineSeriesX As New LinearAxis()
                    LineSeriesX.HorizontalLocation = AxisHorizontalLocation.Left
                    LineSeriesX.AxisType = AxisType.Second
                    'LineSeriesX.Title = ""
                    LineSeriesY.VerticalAxis = LineSeriesX
                    LineSeriesY.HorizontalAxis = horizontalAxis
                    RadChartView1.Series.Add(LineSeriesY)

                    LineSeriesY.CategoryMember = "DateTime"
                    LineSeriesY.ValueMember = "PV"

                    LineSeriesY.DataSource = SingleHistory
                    'Form2.DataGridView1.DataSource = SingleHistory

                    Dim controler As New ChartTrackballController()
                    AddHandler controler.TextNeeded, AddressOf controler_TextNeeded
                    RadChartView1.Controllers.Add(controler)

                End If
            Next


Private Sub controler_TextNeeded(sender As Object, e As TextNeededEventArgs)
        Dim dataPoint As CategoricalDataPoint = TryCast(e.Points(0).DataPoint, CategoricalDataPoint)
        e.Text = String.Format("{0} : {1}", dataPoint.Category, dataPoint.Value)
End Sub

Hi! First I am new in telerik controls :)

I want use this control (Q3 2014 version) in the vertical orientation and with a background image (i draw this image). Good, set the background image is not a problem, only needs modificate BodyElement property in the RangeSelectorElement. The problem is to set a vertical orientation (in the RangeSelectorElement), this not work fine. The buttons in the borders of the control not work in the correct direction, and when i try move the selected range with the mouse it´s do strange things.

Thanks!

I've got a RichTextEditor that I'm filling with the output from an HtmlFormatProvider.Import

After I've imported, I'd like to change the font and font size for the entire document.  Is there a way to do this?

Hi,

I'm unable to close all MDI childs in once.
I've used the following code:

I am building a RadScheduler application via a demo that I found online by a member of the Telerik team.  I have everything working but when I try and expand the calendar to 3 Rows (MultiViewRows = 3) and attempt to save it, it throws the following error:

Property accessor 'ZoomLevel' on object 'RadCalendar1' threw the following exception: 'Object reference not set to an instance of an object.'

Thanks for your help!

Hi there,

If someone can shed some light, I have purchased the license for winforms library over the phone, but can't seem to find the development (non-evaluation) library. When login-in to telerik.com the 'Products' sections doesn't have any product registered. How do I obtain the control library that can be used in production.

Any idea?

Thanks in advance.
