We are migrating from Scheduler to ScheduleView because of performance issues with the Scheduler control. Searching online for help on migration didn't return anything useful. So I was trying to see if anyone else had went through this migration and if they can share their experience.

We use the Scheduler control heavily with many of its APIs and seems like many of them are not available in ScheduleView.

Sample code using Scheduler is listed below.

Thanks!

Hi,
 i have this sample code:
  RadPane formRadPane = new RadPane() { Header = "Not Document Pane", CanDockInDocumentHost = false };
            Canvas cReference = new Canvas();
            Image imgBg = new Image(new uri("Images/0.png"));
            imgBg.Width = 2000;
            imgBg.Height = 1980;
            cReference.childer.Add(imgBg);

            TextBlock txtBlock = new TextBlock();
            txtBlock.Text = "This Pane Cannot be docked in to document host";
            Canvas.SetLeft(txtBlock, 20);
            Canvas.SetTop(txtBlock, 20);
            cReference.childer.Add(txtBlock);

            FormRadPane.Content = cReference; 

when program run , the cReference's content Uncontrolled by formRadPane .that means cReference's content exceeds window area B.
How do I resolve this problem?

I have a RadNumericUpDown control, with default value of 0.00; but I would like to do the following: when the user clicks in it: the cursor position is placed at the beginning and when the user types, it overwrites the value.  

Can this be achieved?

EDIT: in fact what I want is to put the RadNumericUpDown in overwrite mode. Can this be done?

EDIT 2: for now I found this workaround,which puts it in overwrite model:

        private bool _lengthInputInsertActivated = false;
        private void LengthNumericUpDown_GotFocus(object sender, RoutedEventArgs e)
        {
            if (!_lengthInputInsertActivated)
            {
                KeyEventArgs e1 = new KeyEventArgs(Keyboard.PrimaryDevice, Keyboard.PrimaryDevice.ActiveSource, 0, Key.Insert);
                e1.RoutedEvent = Keyboard.KeyDownEvent;
                InputManager.Current.ProcessInput(e1);
                _lengthInputInsertActivated = true;
            }
        }

I found an issue in http://www.telerik.com/community/forums/silverlight/scheduleview/scheduleview-throws-an-error-when-cancel-create-new-appointment.aspx and have a similar issue when i cancel a createnew in the appointmentcreating event by setting e.cancel = true when there are no appointments in the obseverablecollection of a custom appointment type. I tried creating a sample app with as close to the scenario I could and it did not get the exception. I get the below exception any guidance would be greatly appreciated. This the WPF ScheduleView.

Hi.

The user changed the calenderview / selecteddate
Sample:
today = 2011.05.20
user changed to 2009.01.02

In my Button i set the current date:

calendar.SelectedDate = Datetime.ToDay;

Before i do this:
if (calendar.DisplayMode != Telerik.Windows.Controls.Calendar.DisplayMode.MonthView ) 
{ 
    calendar.DisplayMode = DisplayMode.MonthView; 
}




But the calnder doesn´t show the correctly date!
Why?

If a GridView has a selection mode of Extended, is there a way to allow selection of rows by clicking on the selected row and dragging the mouse? if you click on a selected row and drag the mouse, no other rows get highlighted.

Hi,

I have the following structure in my application:
RadOutlookBar
    -RadOutlookBarItem
        -RadPanelBar
            -RadPanelBarItem
                -RadTreeView (with Items)

So, a RadOutlookBar with a RadOutlookBarItem contains a RadPanelBar with RadPanelBarItems. The RadPanelBarItem contains a RadTreeView with RadTreeViewItems.

In the RadTreeView is also a RadContextMenu.

When I right-clicked on a TreeViewItem of the TreeView, the ContextMenus opened-event is fired and ContextMenu.GetClickedElement<RadTreeViewItem>(); will return the right RadTreeViewItem. Then I click on a MenuItem and the ItemClick-event is fired. So far, so good.

Well when I do this a second time, the ContextMenu.GetClickedElement<RadTreeViewItem>(); returns the RadPanelBarItem which contains the TreeView.
As I see the RadPanelBarItem inherits from the RadTreeViewItem and the documentation says, GetClickedElement<T>() will return the top-most element of T. I think this is an incorrect behavior, because it returns two different elements and the second time the top-most element of T.
The error occurs, when at the first time the ItemClick-event of the ContextMenu was fired, after a MenuItem was clicked.

Got it?

GetClickedElement<T>() should always return the last element (the innermost) of T or am I wrong?

Thanks,
Daniel

Hello

I have a ControlTemplate where I want to bind the datacontent.

<Button Content="Button" HorizontalAlignment="Left" VerticalAlignment="Top" Width="75">
    <Button.Template>
        <ControlTemplate>
            <StackPanel>
                <telerik:RadComboBox ItemsSource="{Binding ListCombo, Mode=OneWay}"  
                    Text="{Binding Filter.SelectedText, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" IsEditable="True"  
                    IsSynchronizedWithCurrentItem="True" IsFilteringEnabled="True"  Margin="0,0,0,81" />
            </StackPanel>
        </ControlTemplate>
    </Button.Template>
</Button>

 
Now it doesn't work properly but if I use only the control like below it work properly:

<telerik:RadComboBox ItemsSource="{Binding ListCombo, Mode=OneWay}"  
      Text="{Binding Filter.SelectedText, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" IsEditable="True"  
       IsSynchronizedWithCurrentItem="True" IsFilteringEnabled="True" Margin="0,0,0,81" />

 

What can I do to use it into a controltemplate?

Thanks in advance,

Hi there,

I created a custom filter control as user control in my WPF application. I have a button in my MainWindows.xaml which clear all filters programatically for GridView. Everything works fine. when i click on button, it clear all filters and load grid data again, but it didn't clear filter's appearance in GridView. can you please suggest me how should i change appearance of filters in GridView when click on button?

Floating panes doe not move smoothly when I move them around with the mouse. They jerk about 1cm at a time.
The complete WPF Window moves smoothly.

This problem only occurs on my desktop PC not on my far less powerful notebook.
