Windows modal

I created a form and I want it to be modal, so users can't interact to what is behind this form.

I've already tried to set "FormBorderStyle" to FixedDialog, but I still can interact with contents below this window.

Am I missing something?

Thanks!!

Changing forecolor on selected tab

Hi.

I'm using the Breeze theme with default values on this pageview control.

Boss says he doesn't like the black on grey appearance of the tab text as they'll be difficult to see. He wants me to change the forecolor of the selected tab to white. (I thought I'd change the theme but 5mins with the theme editor terrified me)

How can I achieve this please?

How To Create Chart in RadChartView With one Vertical arc

Also, I started drawing a chart using ScatterLineSeries. Unfortunately, the problem with this is that the peaks and descents in this chart model are not what I want, and sometimes the chart is somewhat unusual. For a better explanation, I will add the charts I have prepared and the charts I intend to add. Please advise you on how to make a perfect match like the sample image.

Draw route directly with list of coordinates not list of waypoints

Hello,

Do you know if it's possible to draw route directly from coordinates (precalculated with address, town stored in database) ?

I can just use WayPoint from routerequest object, but it's a argument type string ?

In BingMapsRESTToolkit project, it's possible to set coordinates directly to calculate a route ?

But I don't found options with RadMap ?

Do you know if it's possible to add this option with a legacy (inherit) or not ?

Dim oRequest As New RouteRequest()
With oRequest
.DistanceUnit = DistanceUnit.Kilometer
With .Options
.Mode = TravelMode.Driving
.Optimization = RouteOptimization.Time
.RouteAttributes = RouteAttributes.All
.RouteAvoidance = RouteAvoidance.Highways
End With
With .Waypoints
STRING NOT POINTG
End With
End With

Thank you

Best regards

Name with icon

Hi there!

Im working with property grid, and I need to put an image with property name.

I have achieved it, but I need give some margin betwen image and text.(See attached image)

I used that code:

Private Sub PropertyGridParams_ItemFormatting(sender As Object, e As UI.PropertyGridItemFormattingEventArgs) Handles PropertyGridParams.ItemFormatting

e.VisualElement.Image = New Bitmap(ImagePath, New Size(18, 18))

e.VisualElement.ImageAlignment = ContentAlignment.MiddleRight

End Sub

How can I set custom image without cover the text?

Thank you!

CartesianMarkedZone annotation offset

Hi,

I'm trying to create a marked zone that goes between two points in a step line series, but instead the zone runs from the centre of one category to the next.

Is it at all possible to offset the zone or otherwise transform my data for the chart so that I can get the effect I'm going for? I've attached a quick screenshot showing the actual area in grey and where I would want it as a red outline.

Thanks
