Hi there,

I have a project with a RadScheduleView.

The viewDefinitions are added dynamically when I first open the App. There are 5 of them : day / week / workweek / month / timeLine by default.

In this configuration, when the activeViewDefinition is the MonthView and I click either on a "weekHeader" or a "dayHeader" to go to the corresponding week or day, it takes up to 25s.

Interestingly though, going from WeekView to DayView by clicking on a "dayHeader" in the WeekViewDefinition is almost instantaneous. So I deduced it has something to do with the way the view is displayed (weekView and DayView share the same layout, if I am not mistaken)

I have used DotTrace to try and find where the problem lies, and it appears almost all of the 25s are spent in MeasureOverride() (see attached screenshot) So my guess seems to be right, but I am puzzled as to what could produce such a loss of time on my part.

Do you know of something that could cause such a behavior ?

(nb: I use the metro Theme on the RadScheduleView)

CellEditTemplate binding

I'm attempting to bind a RadListBox within a CellEditTemplate but for some reason it isn't working. I've attempted to bind a RadListBox outwith the GridView and it works fine.

<telerik:GridViewDataColumn Header="Actionees" UniqueName="ACT856">

<telerik:GridViewDataColumn.CellEditTemplate>

<DataTemplate>

<telerik:RadListBox ItemsSource="{Binding Path=Actionees}" DisplayMemberPath="FullName" SelectedValuePath="IdentityId" />

</DataTemplate>

</telerik:GridViewDataColumn.CellEditTemplate>

</telerik:GridViewDataColumn>

Am I missing something?

Styling and support for Touch

I'm building a business application in WPF that needs to be usable from a kiosk's touch screen. No real need for fancy multitouch or gestures, but I do need basic controls that handle touch events and the ability to style the controls to make them larger for better usability.

Can the Telerik WPF controls handle touch events and easily be styled appropriately? Is there anything like the MetroTouch skin for WPF? Anyone else using the Telerik WPF controls for a basic touch-able application?

Thanks!
Jeremy

Get WPF RadGridDataGrid row and cell

Hello, I would like to know how I can get the value of a particular row / column in RadGrdiView of Wpf
like a telerik web gridview (findcontrol)
Actually I can get the value in a DataGrid wpf, that is my function

Private Function GetCellValue(ByRef dataGrid As DataGrid, ByVal row As Integer, ByVal column As Integer) As String
Dim temprow As DataGridRow
Dim rowview As DataRowView
Dim cellValue As String
GetCellValue = ""
Try
temprow = dataGrid.ItemContainerGenerator.ContainerFromIndex(row)
rowview = temprow.Item
cellValue = rowview.Item(column).ToString
Catch ex As Exception
cellValue = ""
End Try
Return cellValue
End Function

But when I do the same with telerik, I cant, that give the next error
Unable to cast object of type 'Telerik.Windows.Controls.GridView.GridViewRow' to type 'System.Windows.Controls.DataGridRow'.
if you can give me a solution, will be grateful

How to add radpanegroup to a rad split container?

hello all, I use the follwing code to create a radsplitcontainer dynamically and it works perfectly fine.

However when I try to add a pane group (commeneted code) I couldn't even see the split container showing to the right side of the window

Any suggestions, please?

Telerik.Windows.Controls.RadSplitContainer RightSplit =

new Telerik.Windows.Controls.RadSplitContainer();

RightSplit.InitialPosition = Telerik.Windows.Controls.Docking.DockState.DockedRight;

RightSplit.BorderBrush = Brushes.DarkSlateGray;

RightSplit.BorderThickness =

new System.Windows.Thickness(3);

RightSplit.Width =

100;

RightSplit.IsEnabled =

true;

RightSplit.Visibility = Visibility.Visible;

MainContainer.Items.Add(RightSplit);

//Telerik.Windows.Controls.RadPaneGroup thispaneGroup = new Telerik.Windows.Controls.RadPaneGroup();

//thispaneGroup.Width = 100;

//RightSplit.Items.Add(thispaneGroup);

Regards
RK

RadPieChart with hollow middle

I have been looking around for how to do a pie chart with a hollow middle (see the attachment), but have come up empty so far after searching for information on RadPieChart and PieSeries in particular, and for creating my own Path or Style in general. What would be the strategy to do this kind of pie chart?

I am building the PieSeries in C# code and not in XAML, so C# would be greatly appreciated. Thanks.

How to clear routed events from EventManager ?

Hi there,

I am currently having troubles with RoutedEvent in WPF. I made a simple example only using native WPF components. The example is made of a button executing a long term synchronous task the first time it's hit and showing a message "Already executed" all other times.

What you have to do to reproduce my issue is to click the button once, and when the task is executing click a second time => After finishing the first task the second click event is going to trigger a second execution => "Already executed". I want to consume any user input during the execution before it triggers an event.

How could I do that ?
