WHile attempting to modify the style of the Scheduleview component I followed the instructions for editing the template and binding to my UI.

After editing the copy now my scheduleview control does not show the view selections. The group with the date and time picker is shown but no day, week, month selection. If I unbind control to the template normal view selection is restored. I dont understand how to override this part of the control.

In my code I previousely had this in the xaml:
                        <telerik:DayViewDefinition DayStartTime="6:00:00" MinorTickLength="15min" MajorTickLength="1h"/>
                        <telerik:WeekViewDefinition DayStartTime="6:00:00" MinorTickLength="15min" MajorTickLength="1h"/>
This is still in the xaml.

I assumed that editing a copy would start from the same settings as default. What is the fix? I include the template as created by expression blend.

Explicit UpdateSource in Radcombobox?
Hello Telerik,
                       I have one clarification in radcombobox..
How to get Values when Focus is in RadcomboBox?
<telerik:RadComboBox IsEditable="True" Text="{Binding Path=District,Mode=TwoWay, UpdateSourceTrigger=LostFocus, NotifyOnValidationError=True, ValidatesOnDataErrors=True, ValidatesOnExceptions=True}" Margin="103,5,33,0" Name="rcboDistrict" TabIndex="8" FontSize="11" IsDropDownOpen="False" Grid.Column="2" Grid.Row="1" VerticalAlignment="Top" Height="24" />
In XAML i am setting UpdateSourceTrigger=LostFocus..
if suppose focus is in Radcombobox and client will save the detail.That time radcombobox value not getting..

in this project i am using radmenu for displaying Save,Modify Items..If suppose Focus is in TextBox mean i am Updating manually from the following Code..
this.Dispatcher.BeginInvoke(new Action(() =>
            {
                  if (Keyboard.FocusedElement.GetType() == typeof(TextBox))
                  {
                     BindingExpression exprLastName = ((TextBox)Keyboard.FocusedElement).GetBindingExpression(TextBox.TextProperty);
                  exprLastName.UpdateSource();
             }
               //Implementation
 }));

My problem is i want to Update radComboBox also
The above code i am changing RadComboBox instead of TextBox..But its not working...
I find Debugging in runtime
KeyBoard.FocusedElement.GetType() value is PickerTextBox... But focus is in radComboBox

I don't know why pickerTextBox Comes instead of radcomboBox ?
How to update radCombobox value? any suggestions are more welcome...
(I know UpdateSourceTrigger=PropertyChanged .Here i don't want Bcoz i am doing validation in Business object level.
if suppose i am using Property changed each and every character its goes validation thats why i am avoiding..)

RadMenu Problem?
Hello Telerik Team,
                              I have one problem in my WPF project.Let i explain in detail

In my UI contains three TextBoxes..
<Label Content="First _name:" HorizontalAlignment="Right" Margin="0,40,408,247" Target="{Binding ElementName=firstNameTxt}" />
        <TextBox Margin="101,40,101,247" Name="firstNameTxt" Text="{Binding Path=FirstName, ValidatesOnDataErrors=True, =LostFocus}"  />
        <Label Content="_Last name:" HorizontalAlignment="Right" Margin="0,72,408,216" Target="{Binding ElementName=lastNameTxt}" />
        <TextBox Margin="101,72,101,216" Name="lastNameTxt" Text="{Binding Path=LastName, ValidatesOnDataErrors=True, UpdateSourceTrigger=LostFocus}"  />
        <Label Content="E-_mail:" HorizontalAlignment="Right" Margin="0,104,408,184" Target="{Binding ElementName=emailTxt}" />
        <TextBox Margin="101,104,101,184" Name="emailTxt" Text="{Binding Path=Email, ValidatesOnDataErrors=True, UpdateSourceTrigger=LostFocus}" />
All are set into UpdateSourceTrigger=LostFocus;
and also i have standard menu bar
<Menu Height="23" Name="menu1" VerticalAlignment="Top">
            <MenuItem Header="File">
                <MenuItem Header="Save" Click="MenuItem_Click" />
            </MenuItem>
        </Menu>
The menu bar purpose is saving the details to database..
Every time after entered value in textbox atleast one time i change focus to another control then only
the values are updated.Problem is if i enter third Textbox value mean here i change focus to second textbox or first textbox then only Third box value updated.

Here i want to update third box value without changing focus to firstbox or second box.. 
so i make some codes in Codebehind it comes,
public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
        }
  
        private void Window_Loaded(object sender, RoutedEventArgs e)
        {
            this.DataContext = Customer.CreateNewCustomer();
        }
  
        private void MenuItem_Click(object sender, RoutedEventArgs e)
        {
              
            if (Keyboard.FocusedElement.GetType() == typeof(TextBox))
            {
               BindingExpression exprLastName = ((TextBox)
                   Keyboard.FocusedElement).GetBindingExpression(TextBox.TextProperty);
               exprLastName.UpdateSource();
            }
            MessageBox.Show("Passed\n" +
                    ((Customer)this.DataContext).FirstName  + "\n" +
                    ((Customer)this.DataContext).LastName  + "\n" +
                    ((Customer)this.DataContext).Email);
         }
    }
The Binding expression binding value when still focus in third TextBox also...(not leaveing focus to other control)

after that i am clicking save in menuItem all values are comes correctly.Third value also updated.

After that i am changing standard menubar to RadMenu .
Here also i am doing same process.but its not return thid textbox value..

I realize where is the mistake comes from 
        if suppose i am using standard menu and the focus is in third textBox
that time i am clicking save means inside save method comes Keyboard.FocusElement=TextBox  (finding using debugging)

        same time if i am using Radmenu and the focus is in third textbox
that time i am clicking save means inside save method comes Keyboard.FocusElement=Save will come not TextBox..

I don't know why Telerik.wimdows.controls.Radmenu Header.save come instead of Textbox
can anybody give correct solution? 
     give me solution in detail..
Thank you.....

RadDock.FakePopup steals my focus
Hi,

I'm trying to add context help to my application following the method described here
http://www.codeproject.com/Articles/36117/Easy-help-with-WPF.aspx

In the main window I'm using the RadDocking to host some children views. I'm following the standard procedures described in the RadDocking document, using DocumentHost, RadSplitContainer and RadPaneGroup.

When I start the app and press the F1 button without clicking anything else, I expect the mouse click to be originated from the main Window. But when I debug I found that the sender of the keyboard input is from a Telerik.Windows.Controls.RadDock.FakePopup.

I can't find any document regarding this class. And I have no idea what it is and why it took the keyboard focus by default after my app starts.

One thing for sure is, it's invisible.

The only solution is to click somewhere on my main window first to get the focus back to where it should be. Then my F1 works as normal.

Can anyone help with it? Why RadDocking brings a FakePopup in my app and set it on focus? Is it something to do with the floating mode of the dockable panes? Urgently waiting for answers. 

Many thanks!

P.S. I'm going to prepare a demo solution to showcase the point. But actually it's very easy to reproduce. You just need to enable the context help and add a normal RadDocking control in the main window, then put a break point at the HelpProvider's Execute method. During runtime, check the sender and you will see the FakePopup.

How do I style the row indicator header cell
On the top  left corner there is a blank header cell above the row indicator columns. How do I style this?

Also I've managed to style the column header cells, but when I drag them into the grouped row the style changes back to the original blue. How do I apply styles to those little group labels?
