Hello,

FOr the char I use the ItemToolTipFormat
<telerik:SplineSeriesDefinition ShowItemLabels="False" ShowItemToolTips="True"
ItemToolTipFormat="Month: #DATAITEM.Month
Intake: #DATAITEM.Intake{C2}
Target: #DATAITEM.Target{C2}
Turn Over: #DATAITEM.TurnOver{C2}
Maintenance: #DATAITEM.Maintenance{C2}" />

For the #DATAITEM.Target{C2} would it be possible to use a custom convertor on the value?

Adding reference to chart controls breaks intellisense in XAML

Trying to familiarize myself with the 4.5 WPF chart controls, but I found that adding a reference to Telerik.Windows.Controls.Charting breaks all intellisense in XAML. Same appears to go for Controls.Chart, and Controls.Data.

I'm using a build that seems to have the .DLLs dated Oct 17th.

Changing MouseOver/Selected slot brushes

Hi,
I am working on a month view in the ScheduleView control, and I've been trying to find a way to change the brushes of the slots (ie the TimeRulerMonthViewItem) when they are hovered over or selected.
Another related issue is srtetching that selection/hover border to fill the entire slot - instead of just under the GoToDayButton I want it to also show behind the button (the button is transparent of course).
Is there a way to apply this style changes?

Please see attached photo (hope it's comprehensible).

Thanks,
Nadav.

[Solved] How to get Member, Operator and Value from Filter events

Hi Telerik Team,
Almost in all of your examples of Filtering concepts I found, you directly given the Member, Operator and Value for FilterDescriptor. But, I wish to give that values dynamically. How to achieve it? I'll be very thankful to you if suggests any good idea for this..

Private

Sub Me_Filtering(ByVal source As Object, ByVal e As GridViewFilteringEventArgs) Handles Me.Filtering

I tried to get this from e, but couldn't get.

Private

Sub Me_Sorting(ByVal source As Object, ByVal e As GridViewSortingEventArgs) Handles Me.Sorting

But, I can get Member, SortingState from e in Sorting events.

Please Help..

Thanks & Regards,

Need help on changing the style of filter icon for RadGridView

Hi guys,

I posted this question in an other board and nobody answered so I am reposting this here since Telerik admins are more active in this place.

In this picture, you can see that the "Country" column has been highlighted and is active (i.e. has Distinct Filter). But in this case, that little wine-glass-like icon on the left is grey instead of orange. Do you know how I can make that icon change colour when the column is active?

The classes that are involved are RadGridView, a class that overrides IFilteringControl, and a set of GridViewColumns.

Thanks.

Export to PNG

Hello

I'm trying to export shapes to a png file using exportToImage() method in RadDiagram.
However, the generated png image is all black, that is every pixel is black.
The RadDiagram I generated is not in the visual tree.

I did something like this:

var diagram = new RadDiagram();

diagram.Load(shapeData);

using (FileStream stream = new FileStream("C:\\test\\test-1.png", FileMode.OpenOrCreate, FileAccess.Write))

{

diagram.ExportToImage(stream);

}

Is it because RadDiagram is not in the visual tree? Is there a work around?

Thanks

The Tag 'RadDataServiceDataSource.DataSourceContext' does not exist in XML namespace

Hi,

I just installed RadControls for WPF v2012.3.1017.40. I have VS2012 v11.0.50727.1 RTMREL and I'm targeting .NET 4.0.

I'm getting the following error when referencing RadDataServiceDataSource:

Error 1 The tag 'RadDataServiceDataSource.DataSourceContext' does not exist in XML namespace 'http://schemas.telerik.com/2008/xaml/presentation'. Line 55 Position 22. D:\SVN\branches\DataExtractor-2.0.x\Workbench\MainWindow.xaml 55 22 Workbench

Here is the XAML in question:

<Window

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

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

xmlns:myvm="clr-namespace:SmartProcure.Workbench.ViewModels"

xmlns:mycv="clr-namespace:SmartProcure.Workbench.Converters"

xmlns:mdmhub="clr-namespace:SmartProcure.Workbench.MdmHub"

xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"

x:Class="SmartProcure.Workbench.MainWindow"

Title="SmartProcure DataExtractor Workbench" Height="800" Width="1024" MinHeight="800" MinWidth="1024" Closed="Window_Closed">

...

<telerik:RadDataServiceDataSource x:Name="dataServiceMdmHub" Height="100" Width="100" AutoLoad="True" PageSize="25" QueryName="ImportQueue">

<telerik:RadDataServiceDataSource.DataSourceContext>

<mdmhub:MdmHubEntitiesContext/>

</telerik:RadDataServiceDataSource.DataSourceContext>

</telerik:RadDataServiceDataSource>

I tried many recommendations from other posts, but none have fixed the problem. I can see in Object Browser that RadDataServiceDataSource has a DataSourceContext property, but VS is not able to find it to compile the project.

Thanks in advance
