Row Indicator not working when Custom Filter Row is used

Hi,

After implementing the custom filter row in the grid view, I noticed that the row indicator (column 0 when RowIndicatorVisibility = Visible) is not functioning correctly. The background brush changes as you select rows, but the arrow (>) just stays on the first row.

This behaviour is the same in your demo application.

Thanks.

[Solved] Styling a RadGridView row not possible using Expression Blend

I'm trying to tweak the style of the new Expression Dark skin and I'm following the tutorials about how to do this using expression blend. However the tutorial instructs that I should do the following:

Object -> Edit Additional Styles -> RowStyle -> Edit A Copy

However, when I attempt this the Edit A Copy option is greyed out and unselectable. Does any one have any idea why this is, or how to get around it?

View changed event

Hello,

I need to adjust appointment panel length every time ActiveViewDefinition is switched to prevent content scroll.

I try using MaxTimeRulerExtent property but can't find proper way to update it. Its value should be calculated as appointmnet panel length substract total headers length. The headers length is updated within MeasureOverride(). But ActiveViewDefinition changed event is rised prior to Measure/Arrange when I change active view.

What event should I listen or what another way suits better?

Thanks,
Anatoly

Setting focus/scroll to a certain time.

Hello,

First of all congrats on the new WPF Q3 SP1 release. The WPF controls looks really great.
For the ScheduleView I really like the SpecialSlots styling, this is exactly what we needed.

So here's my question,

I'm using a group filter on the resources that are in the selected appointment. That way only resources that have a correlation with the selected appointment are shown (along with their availabilities). Now, when I change the a resource for the selected appointment, the calendar is updated accordingly (showing the new resource and it's availability). Until now everything is as expected. However after the update the scroll bar is back on top and not where it was before. So how would I set the scroll bar.

I see several options.
1. Make it possible to scroll to a certain time. (independent of zoom level)
2. Autoscroll to the selected appointment.

How would you guys go about this?

Thanks,
Nico

ContextMenu on MapPolylines does not work

Hi,

I'm trying to add Context Menu to MapPolylines and somehow it is not displaying the context menu. My requirement is to Right Click on MapPolyline and select Hide Polyline from Context Menu. Please see the code below:

Registering this event when drawing Polyline

private void techpolyline_MouseRightButtonDown(object sender, MouseButtonEventArgs e)

{

MapPolyline rightClickPolyline;

ContextMenu mainMenu = new ContextMenu();

mainMenu.Background =

Brushes.LightBlue;

mainMenu.Height = 50;

mainMenu.Width = 120;

MenuItem baseItem = new MenuItem();

baseItem.Width = 120;

baseItem.Header =

"Select Action";

baseItem.Background =

Brushes.Blue;

baseItem.Foreground =

Brushes.White;

baseItem.FontWeight =

FontWeights.Bold;

mainMenu.Items.Add(baseItem);

MenuItem hidepolygonItem = new MenuItem();

hidepolygonItem.Width = 120;

hidepolygonItem.Header =

"Hide Polyline";

mainMenu.Items.Add(hidepolygonItem);

//hidepolygonItem.PreviewMouseLeftButtonDown +=new MouseButtonEventHandler(hidepolygonItem_PreviewMouseLeftButtonDown);

if (sender.GetType() == typeof(MapPolyline))

{

rightClickPolyline = (

MapPolyline)sender;

rightClickPolyline.ContextMenu = mainMenu;

}

I use the same logic to MapPinPoint items and Pushpin items and it works. Any help is appreciated.

Regards!!
Paddy

[Solved] Performance issue with largedatasets and HierarchyChildTemplate

I am running into a performance issue where I have a HierarchyChildTemplate that shows a RadGridView with 10000+ data items. The initial databinding to the toplevel works very fast but trying to expand the hierarchy takes an incredible amount of time. I've tried using different combination the following to improve performance but they don't have any effect on the internal RadGridView.

DataLoadMode="Asynchronous"

ScrollMode="Deferred"

EnableRowVirtualization="True"

Is there a way to improve the performance or is this a bug?

Thanks,
Shawn
