Change the shape of a Scatter chart item/point to a custom shape

Hi,

I have a scatter chart with three series and I need to change the points in two of these series to a plus sign (+). I looked in the documentation but the page below that covers styling does not mention the scatter series.

http://www.telerik.com/help/wpf/radchart-styling-and-appearance-styling-chart-series.html

I tried restyling ScatterPoint and in its template I found the property PointMark.ShapeStyle which appears to be what I need to apply a new style to. But since the Shape is an enumeration I don't know how to proceed. Would you be kind enough to give me a pointer?

Cheers,
Jose

Numerous votes for improvements but not scheduled?

Hi,

there are a number of identical/overlapping issues for the color picker, some with a relatively high vote count

Issue ID 514 - ColorPicker: Add option to define custom RGB/HSL colors - 29 votes
Issue ID 986 - ColorPicker: Add color chooser dialog like in MS Word - 15 votes
Issue ID 3525 - ColorPicker: Generate palette colors that are more similar to the Microsoft Word's - 2 votes
Issue ID 4055 - ColorPicker: Gradient color palette - 1 vote

If these were merged the item would have 47 votes which I think puts it second on the list of unscheduled items. Can you tell me if this is likely to be in the next release? We are looking to integrate with various telerik controls, but this one seems to let the wpf control set down rather from a functionality standpoint and does not meet our requirements.

thanks

Get date from mouse point

Hi Telerik,

I'm trying to retrieve the date of which I have right-clicked.
How can I retrieve a date (in month view) from a given point in the calendar.

Or if it is possible to have right-click also select the date would help me.

What I'm trying to achieve is that I have added a context menu and need to display some checked menu items according to the date being right-clicked (not the selected date).

Thanks in advance!
Best regards,
Kasper Schou

RoutedCommand and floating Pane

Hi,

I'm in this simple situation, my Shell contains 2 regions
in the first region I have a botton with a RoutedCommand associated (RoutedMyCommand)
in the second region I have a RadDocking like this :

<telerikDocking:RadDocking>

<telerikDocking:RadDocking.DocumentHost>

<telerikDocking:RadSplitContainer>

<telerikDocking:RadPaneGroup Regions:RegionManager.RegionName="Body" >

</telerikDocking:RadPaneGroup>

</telerikDocking:RadSplitContainer>

</telerikDocking:RadDocking.DocumentHost>

</telerikDocking:RadDocking>

when I activate a new View ( a new RadPane ) in Body region, the RadPane is initially "Tabbed Document" and it handle correctly the RoutedMyCommand
when the RadPane becomes "Floating" the RoutedMyCommand is not handled by View.

Telerik version 2010.3.1110.35

Thanks, Andrea.

Hierarchical RadGridView Slow Details Expansion

Hello,

I set up a simple WPF window with two grids side-by-side: A Telerik RADGridView and a Microsoft DataGrid. Both grids are set up with 2 levels of hierarchy (master-detail), and are bound to the same data (2 master records, each with 1000 detail records). Both grids have one fixed-width column on the master and detail levels.

On my machine, when I expand a master row on the Microsoft grid for the first time, it takes 4 seconds to display all the details; expanding a master row on the Telerik grid for the first time takes 9 seconds to display the details.

The thing that appears to be taking a long time is rendering the detail rows -- if I limit the height of the detail grid to 200 pixels, it takes less than a second to expand a master for the first time (this is the case with both the Microsoft grid and the Telerik grid).

I reviewed the performance tips/tricks. Is there anything else I can do to reduce the time it takes to expand a master for the first time in the RADGridView?

Any help is much appreciated!

Here is the XAML and code-behind I'm using:

<Window x:Class="MasterDetailPerformance.MainWindow"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

</DataGrid.Columns>

</DataGrid>

</DataTemplate>

</DataGrid.RowDetailsTemplate>

</DataGrid>

{

IList<Detail> details = new List<Detail>();

for ( int index = 0; index < 1000; ++index )

{

details.Add( new Detail() { ID = index, Name = index.ToString() } );

}

return details;

Capturing Keystrokes (ctrl,shift) on Grid

Hello,

I need to capture the ctrl and shift keys after selecting a row on the grid. I can code something using the SelectionChanged and keydown events but it will take a while to perfect. Has anyone already coded this logic?

Thanks
