Docking Compass Offset Problem

I have seen the posts about the Compass being displayed incorrectly when DPI is not 100%, so I checked and that is not my problem. This just doesn't seem to me to be a problem that would need to be voted on to get it taken care of. We were almost set to buy the product on Monday, and then I ran into this. Please tell me it will be fixed.

Thanks in advance,
Steve

PS - Here's some additional information. Apparently the control does not consider having the Windows 7 taskbar on the left of the screen, so on my main monitor, not only is it offset from the top, but also from the right. Both my monitors are set at 1920x1080.

RadGridView smooth scrolling

Does anyone know of an example of how to do smooth scrolling similiar to the Xceed grid with the RadGridView.

Basically what they do is allow you to sort filter and group without paging and just with the scroll bar. Say you have 1 million records you can scroll through them without hitting the database for all the data. It just gets the 200 at a time, you can set the value as well. All you need to do is give it a Iqueryable and it does the rest.

Can you do this with the RadGridView?

How to show a text over mappolygon at runtime

Hi,
My requirement is to show the text over the map polygon at runtime.
From the xaml we can do this like:

<telerik:MapPolygon Points="56,-100 56,-108 48,-108 48,-100" Fill="Green" Stroke="Red"

StrokeThickness="4" CaptionLocation="52,-104">

<telerik:MapPolygon.CaptionTemplate>

<DataTemplate>

<Grid Background="Yellow">

<telerik:MapLayer.HotSpot="0.50.5">

<TextBlock Text="My Custom Text" />

</Grid>

</DataTemplate>

</telerik:MapPolygon.CaptionTemplate>

</telerik:MapPolygon>

But from the code behind how we can do the same thing.

MapPolygon CreatePolygon(IEnumerable<Location> points, string areaName)

{

var polygon = new MapPolygon();

polygon.Points = this.pins.Points;

polygon.ToolTip = areaName;

// also I want to set the area name over the MapPolygon

return polygon;

}

[Solved] Drag-n-drop usercontrol on map

Hi,

We are developing a new application. One of the feature that we are planning is a floor plan interface with ability to place controls on the map, and we are evaluating whether the RadMap is the right module to use.

The floor plan would be a single image, I figure this is possible by implement a custom ImageProvider
The zoom-out level needs to be limited to when the image fills the window
User need to be able to add new controls to the map, which can be a custom WPF user control, or a RadGauge. The control will be fixed at a map coordinate.
User needs to be able to drag-n-drop any control to any place on the map, and also rotate the control. The new placement and angle will be remembered.
User needs to be able to remove controls from the map (maybe through context menu on the control)

And hopefully 3-5 can be achieved through data-binding.

Is the RadMap module the right tool for what we needed? or is there some other control that would suite this scenario better?

[Solved] ContextMenuOpening event lost in Pane Client

I have a client control in my RadPanes that uses the ContextMenuOpening event to create dynamic menus if the user right clicks on images in the control. If the RadPane has the Right click ContexMenu with the dockable options my control does not get ContexMenuOpening events anymore.

Solution for this is to set the ContextMenuTemplate to Null, but I would prefer to have the ContexMenuOpening event in my Control even if the RadPane has a ContextMenu. If my Control does not handle the ContextMenu event the RadPane could take it. May be this can be added to the wish list.

[Solved] FilteringControl Prepare firing OnCollectionChanged?

I am overriding the FilteringControl to remove IsContainedIn and IsNotContainedIn. My code looks like this:

public class StringFilteringControl : FilteringControl

{

public override void Prepare(GridViewBoundColumnBase column)

{

base

.Prepare(column);   // <-- This fires OnCollectionChanged if actions are removed

var vm = this.DataContext as FilteringViewModel;

if (vm != null)

{

vm.AvailableActions.Remove(FilterOperator.IsContainedIn);

vm.AvailableActions.Remove(FilterOperator.IsNotContainedIn);

}

The base.Prepare call is firing a collection changed event if actions are removed, and this is causing an unwanted refresh of the grid every time the filter control is opened by the user. If I have a custom filter control, but do not remove actions, then the collection changed event is not fired, so the removal of actions seems to be the reason why the event is triggered.

I do not want the collection changed event to fire, or I need a way to know that the event was fired by the Prepare. Is there a way to prevent this event from firing?

Thanks for your help.
