Extremely high CPU usage when dragging panes

Hi

When moving around undocked RadPanes, I am seeing very high CPU usage - around 70% according to the Windows Task Manager. My app is a very basic one with some RadDocking controls, and very little else - almost no procedural code. My CPU is a Core2Duo E6750, and my GFX card is a GeForce GTS450. When I drag the main window around, the CPU only jumps to around 10%. I'm running a release build.

Any idea why I'm seeing such high CPU usage? Could I be doing something wrong?

For reference, doing the same thing in the Telerik Demo app causes a CPU usage of about 35% - so about half what my own app takes, but still very high for such a basic operation.

Thanks

Appointment Editing does not work after adding Style Selector

Hi,

I want to customize the Appointment Item. Therefore I proceeded as described in http://www.telerik.com/help/wpf/radscheduleview-styles-and-templates-appointment-style.html. But after creating the AppointmentStyleSelector nothing happens when I doubleclick an appointment. What went wrong? Are there any triggers missing? Below is the XAML which was generated by Expression Blend (4). I'm using Q1 2011 telerik controls.

thanks in advance,

michael

how to detect same selection?

Depending on how I have set up my combobox, I can detect when a user selects an item. Either the property I have bound to SelectedItem changes, or the SelectionChanged event fires.
But neither of these occur if the user selects the same item again.

Any ideas of how I can detect this?

[Solved] Binding PasswordBox control to create user.

Hi,

I'm trying to use this control for user management, I am aware that you're not supposed to bind to PasswordBox field, and I do not intend to, but I would like to have the field there when you're going to insert a new user or edit a current user (in the case of edit it would be an empty text field).

How would you go about achieving this?

Thanks,
Daryl

Error RadDatePicker

Hi,

I have installed RadControls_for_WPF_Q1_2009_DEV.msi. Then I have created a new VS 2008 WFP C# .Net 3.5 Project.
Everything works fine when I add the RadDatePicker to the Window.

The RadDatePicker shows up on the Window

Two DLLs are added to the project
- Telerik.Windows.Controls > Version: 2009.1.312.35 > C:\Program Files\Telerik\RadControls for WPF Q1 2009\\Binaries\WPF\Telerik.Windows.Controls.dll
- Telerik.Windows.Controls.Input > Version: 2009.1.312.35 > C:\Program Files\Telerik\RadControls for WPF Q1 2009\\Binaries\WPF\Telerik.Windows.Controls.Input.dll
In the XAML File
- xmlns
  
  :telerik=http://schemas.telerik.com/2008/xaml/presentation
- <
  
  telerik:RadDatePicker Height="24" HorizontalAlignment="Left" Margin="10,10,0,0" Name="radDatePicker1" VerticalAlignment="Top" Width="84" />

But now when I start the project VS tells me to find the source RadDatePicker.cs. Original location: c:\Builds\WPF_Scrum\WPF_Team\Sources\Development\Silverlight\Telerik.Windows.Controls.Input\DatePicker\RadDatePicker.cs
Which I can not find on the machine.

When I cancel this I get an Error from the InitializeComponent() function:
Error: XamlParseException occured
'Telerik.Windows.Controls.Input;;;Component\Themes\Calendar\Telerik/Calendar.xaml' value cannot be assigned to property 'Source' of object 'System.Windows.ResourceDictionary'. Object reference not set to an instance of an object. Error at object 'System.Windows.ResourceDictionary'.

Thanks

How to drag ListViewItem to ScheduleView

I have added drag capabilites to one of our listviews so that appointments can be dragged to the ScheduleView using the RadDragDropManager.

RadDragAndDropManager

.SetAllowDrag(resultListView, true);

RadDragAndDropManager.AddDragQueryHandler(resultListView, OnDragQuery);

For the most part everythiing works, but when I grab the scrollbar thumb on the listview and drag it down, it starts a drag operation on the selected listviewitem instead of scrolling down. Also happens when tryng to resize the listview columns.

Any idea how I can get this to react only when dragging the listviewitem within the listview?

[Solved] Filter for enum values don't use specified converters in drop down (equals, not equals)

Hello everyone,

we have a simple RadGridView with one column bound to a enum property of a view model with a converter:

<telerik:GridViewDataColumn DataMemberBinding="{Binding SomeValue, Converter={StaticResource TestConverter}}" />

ViewModel:

public class TestViewModel {

public TestEnum SomeValue { get; set; }

}

public enum TestEnum {

A,

B,

C

}

And the converter code simply translates the bound enum value to a more readable text:

public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) {

var test = (TestEnum)value;

switch (test) {

case TestEnum.A: return "TestEnum with Value A";

case TestEnum.B: return "TestEnum with Value B";

case TestEnum.C: return "TestEnum with Value C";

}

throw new NotImplementedException();

}

The grid is rendered correctly ("TestEnum with Value A"), but all drop downs located in the extended filter are using the raw values ("A", "B", "C") of our enum and not the transformed values for our converter.

Is there a way to work around this issue (beside translating the values prior to binding, i.e. coding a seconding property and doing the translation without a converter)?

Version: RadControls for WPF Q1 2011

FYI - I can provide a simple c# test project in order to reproduce the issue if needed.

Your sincerely,

Christian
