Is there an easy way to select current date and time using the control or I should make such button myself?

thanks in advance

I have two identical  WPF RadGridViews on my form. I want to be able to detect when the GroupHeader has been clicked so that
a) Only one group on each grid is expanded at any one time
b) If the group in radGridDebits is expanded/collapsed, the same group in radGridCredits is expanded/collapsed - i.e. synchronize the group header between both grids.
c) Basically, I'm looking for a GroupHeader.Clicked event but can't find it!!


Many thanks

Hi,

I have declared the following template in my Resource File :
<DataTemplate x:Key="MenuItem">
<telerik:RadMenuItem 
                Margin="0"
                Padding="0"
                Header="{Binding Header}"
IsCheckable="{Binding IsCheckable}"
IsChecked="{Binding IsChecked, Mode=TwoWay}"
IsSeparator="{Binding IsSeparator}"
IsEnabled="{Binding IsEnabled}"
Command="{Binding MenuCommand}"
/>
        </DataTemplate>

<HierarchicalDataTemplate 
x:Key="MenuItemTemplate"
ItemsSource="{Binding MenuItems}"
ItemTemplate="{StaticResource MenuItem}">
        <telerik:RadMenuItem Header="{Binding Header}"
                             IsCheckable="{Binding IsCheckable}"
                             IsChecked="{Binding IsChecked, Mode=TwoWay}"
                             IsSeparator="{Binding IsSeparator}"
                             Margin="0"
                             Padding="0"
                             IsEnabled="{Binding IsEnabled}"
                             Command="{Binding MenuCommand}"/>
</HierarchicalDataTemplate>

And I am using the above resources in RadGridView as below:
 <telerik:RadContextMenu.ContextMenu>
                <telerik:RadContextMenu x:Name="_gridContextMenu" 
Opened="_gridContextMenu_Opened"
ItemTemplate="{StaticResource MenuItemTemplate}"
ItemsSource="{Binding ContextMenu}">
                </telerik:RadContextMenu>
            </telerik:RadContextMenu.ContextMenu>
ContextMenu is a ObservableCollection<ContextMenuController>. 

Now Everything seems to be working except that IsSeperator doesn't work. When IsSeperator is true for a ContextMenuController it still shows as an Item occupied more space than it is supposed to be.

Look at the attached image and see how it shows the RadMenuItem which is nothing but a seperator.

Hi,

I'm having some very odd behaviour by using the Expression Dark resource dictionary for the BusyIndicator in my project. I had everything working perfectly with the default style and settings. I have a requirement to make the background overlay more opaque, so I attached the busy indicator resource dictionary and fired up my application ready to try and tweak it. At this point I have not changed anything in the resource dictionary, only attached it to my project. It seems that this action alone causes the BusyIndicator to fire and cover my whole window with the overlay. If I comment out the line that links the resource dictionary to my project, the problem disappears.

Does anyone have any idea why this might be?

All I want to do is make the grey overlay a little more transparent, so if there is another way to achieve this without editing the resource dictionary that would also help.

Thanks

Hi,

in release notes I saw, that now it's possible to navigate with HOME/END and PGUP/PGDOWN. That's great and it fundamentally works.
But I figured out some problems (in general keyboard navigation):
1. We only need row selection and no cell selection. We worked around this by setting cell selector style to something "invisible".
2. If a row gets selected via ViewModel it isn't brought into view. I worked around this by using ScrollIntoView() when ViewModels SelectedItem property changed. Sometimes I get performance issues, but couldn't reproduce them: the scrollbar moves very very slowly but the grid doesn't get updated. After several seconds it then updates the grid.
3. If I navigate via arrow down/up key very fast, the selected row is not enforced to contain the selected cell. That means there is a selected cell further up/down to the navigation direction than the selected row.
4. Sometimes it is not possible to navigate to the last row via key down (with RowDetails enabled) - the same with the first row and key up
5. If I reach the last row in the grid it looses keyboard focus (it doesn't matter which key invokes the navigation - I tried key up/down, home/end & page up/down.
6. the grid generally behaves very sluggish with keyboard navigation and enabled RowDetails

RadControls tested: 2010.3.1415.40

Hello All,

In WPF, how can I put a RadTreeView directly inside a RadPanelBarItem without highlighting effect?

this is what I've tried:


and this is the style i use:

In this style I basically retemplate the header visual. now with this style applied when i tried to hover the radtreeview, it is highlighted, how can i remove the highlight?
I've tried to add RadPanelBarItem inside the RadPanelBarItem and yeah the highlight there is removed, but how can I do that if the RadPanelBarItem's child is RadTreeView?


Thanks,

What event handles extending the appointment duration by dragging the thumb? I need to use the new values to update the database.

I already have code from handling the update from a drag and drop action. So subscribing to the appointment.PropertyChanged is not what I am looking for. I need something more specific for the drag of the start and end of the appointment.

Thanks,
Rod

Hi,

we have a weird occurence: when are invisible columns in the GridViewColumnCollection of a RadGridView and user drag and reorder columns - then the dragged column and the target column are overlapped (both header and data: as visible on the attached picture). With all visible columns or when invisible columns are grouped at the end of the gridview : this error situation does not happen.

What we doing wrong?

We use the Q3 2010 release of the WPF controls.

Hi

Is it possible to apply transition effects when the selected item in an OutlookBar changes? ie fade out the current content in the main view area, and fade in the new one?

Are there any examples of this?

Thanks
