Drag and Drop Icon sticks to borders of appication

I am using drag and drop in GridView and in Tree.
When draging to application's borders and release - the drag objects stays on the border and not disappear.

The property RadDragAndDropManager.EnableNativeDrag should be False.

If this property is true - the behaviour is different and I have other problems even worse. (crashes and drag is not working when changing tab folders).

Calendar Header with multiple columns

I am using the radCalendar control. We are displaying two columns. The default header has the month in the middle above the two months instead of having each month have it own header. How would I go about adding the months names. I need I18n so I would prefer it be part of the control.

Nevermind we had the ViewsHeader set to false

Tutorial request - Color changer

Would be possible to get a tutorial on how you change colors (using transparent theme) as you have done in the Silverlight sample application "Holiday Planner"? I've downloaded the application but as I'm a designer I find it hard to figure out how it is implimented due to it being a viewmodel project, and VS2010 throwing and exception on MainPage.xaml (Exception was thrown on "DataTemplate": Invalid XAML).

A simple project and tutorial would be VERY helpful as the principle of using a transparent skin and simply dynamically changing some background colors (I think that's what you are doing?) is exactly what I want to do with our application!

Thank you for taking the time to read my request!

Regards,
Murray Eaton

public

DataTable ExcelData { get; set; }

RadGridViewSettings settings = null;

public Window1()

{

InitializeComponent();

}

privatevoid Window_Loaded(object sender, RoutedEventArgs e)

{

ExcelData =

newDataTable();

ExcelData.Columns.Add(

newDataColumn("Col1"));

ExcelData.Columns.Add(

newDataColumn("Col2"));

ExcelData.Columns.Add(

newDataColumn("Col3"));

ExcelData.Rows.Add(

"a", "a1", "a2");

update binded fields in tileviewItem

Hello,
I'll try to simplify my problem. Lets say I create a class with a field named "Title". after creating a few objects of this class type. I set a textbox with binding in my TileViews SmallContent :
<TextBlock Text="{Binding Title}" />

and add my objects to the TileView using "tileview1.Items.add()"

The initial view is good, but now I want to update this value. How do I refer to this field so it will be updated in the TileViewItem?
I've tried to change the "Title" value in one of my objects ( which I added using "tileview1.Items.add()" ), but the value in the TextBox doesn't change.

Bottom line: how do I update a field which is declared in the tileviews dataTemplate?

Thank you

TileView

Strange DateTime behavior

I followed the example regarding DateTime-support on the help site. I more or less copied the code but still I got a real strange behavior that can be seen on attached image (sorry for attaching one directly from Word but it seems it's not possible to delete attached items).

The first picture shows a continuous trendline for five (different) days but the graph places two points on the same day. At first I thought that the "oldest" data point was not showing correctly but after a more thorough look I realized that it's actually all data points except the first that is placed incorrectly.

The second picture shows the result after I changed a date. Some items are now shown on the correct place while some are placed way off.

Am I missing something obvious?

Here's the chart setup:

SeriesMapping seriesMapping = new SeriesMapping(); 

seriesMapping.LegendLabel = "MSFT"; 

seriesMapping.SeriesDefinition = new LineSeriesDefinition(); 

seriesMapping.ItemMappings.Add(new ItemMapping("DateTime", DataPointMember.XValue)); 

seriesMapping.ItemMappings.Add(new ItemMapping("Value", DataPointMember.YValue)); 

chart.SeriesMappings.Add(seriesMapping); 

chart.DefaultView.ChartArea.AxisX.DefaultLabelFormat = "dd-MMM-yyyy"; 

chart.DefaultView.ChartArea.AxisX.LabelRotationAngle = 45;

Drop Target Selection Color

Hello,

I am implementing a drag drop between a listview and a rad treeview. Everything is fine except that when i drag an item to the treeview, the selected hovered item on the treeview does not show.
Is there any 'out of box' solution for this, or it should be implemented manually by detecting the hovered tree view item and changing its color? if it does require manual coding, do you have some short example for it?

Thanks,

DragAndDrop

Implement Type Ahead in Grid

Has anyone implemented type-ahead capability in the WPF RadGridView like in a windows grid where you can click on a given cell, start to type and have the grid position the current row to the row that starts with whatever letters have been typed? If so can you share some code?
