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.


Using: WPF40_2010_2_0812

I'm using the RadGridView in an MVVM application. The SortingState of each column is bound to a property (one per column) in my ViewModel. When I set a new value to these properties in code I expect the sorting of the corresponding column to be updated. However, that doesn't work as expected. The column header indicates that the column is ordered as I specified, but the rows are not ordered. Also, if I update the data in the GridView the sorting I set through code completely disappears.

I've found one perticular interesting scenario:
1. I start the application and load some data into the GridView.
2. I sort the data by column A by clicking the header of this column (works fine).
3. I press a button that invokes a command in the ViewModel that sets the SortingState of column A to SortingState.None (removes the sorting that is) and sets the SortingState of column B to SortingState.Ascending
4. The GridView header now indicates that the data should be sorted ascending by column B and not sorted by any other column. However, the rows are still sorted as before (by column A).
5. Now I fetch some new data (completely replace the old data).
6. The GridView now reverts into my previous sorting order, that is to sort by column A. This is both indicated by the GridView header and by the way the rows are actually sorted.

What am I doing wrong?

Here's how my XAML looks:

And the ViewModel:

Code to fetch data removed for brevity. Note that this is not my actual code so please disregard typos.

Hi,

in my gridview, I have a column base on a bool value and for each rows, for this column, a checkbox is visible. I would like to know if it's possible to center horizontally those checkboxes?

Thank's

Hi,

im using a TreeListView and would like to get an event, when the selection in a ComboboxColumn changes. I can't find any event helping me. Here is my XAML:

		<telerik:RadTreeListView Name="rtlvQuery" Grid.Column="0" Grid.Row="0" IsDragDropEnabled="true" Margin="30" AutoGenerateColumns="False" >
			<telerik:RadTreeListView.ChildTableDefinitions>
				<telerik:TreeListViewTableDefinition ItemsSource="{Binding Filters}" />
			</telerik:RadTreeListView.ChildTableDefinitions>
			<telerik:RadTreeListView.Columns>
				<telerik:GridViewDataColumn DataMemberBinding="{Binding IsActive}" Header="Active" />
				<telerik:GridViewDataColumn DataMemberBinding="{Binding Name}" Header="Name" />
				<telerik:GridViewDataColumn DataMemberBinding="{Binding Description}" Header="Description"/>
				<telerik:GridViewComboBoxColumn ItemsSourceBinding="{Binding AvailableFilterTypes}" DataMemberBinding="{Binding FilterType}"  
												Header="Type" SelectedValueMemberPath="Value"  DisplayMemberPath="DisplayName" />
				<telerik:GridViewDataColumn DataMemberBinding="{Binding IsNegated}" Header="Negate"/>
 
			</telerik:RadTreeListView.Columns>
		</telerik:RadTreeListView>

I use a ItemSourceBinding because the available Combobox is bound to a filtered List of EnumMemberViewModel build by EnumDataSource.FromType<FilterType>( );

I tried the following, that I found in the forum for RadGridView, but thta doesn't seem to work in TLV:

		<Grid.Resources>
			<Style TargetType="telerik:RadComboBox" >
				<EventSetter Event="SelectionChanged" Handler="ComboBox_SelectionChanged" />
			</Style>
		</Grid.Resources>

Any idea, how I could solve this?

Thanks
Hans

Hi,

i am trying to change the selection of a RadComboBox with seperate Buttons.
One to select the previous entry in the RadComboBox and one to select the next.
Is there a way to do that with build-in commands?
Or is there another possibility to do that without Code-Behind?

Greetings,

I'm using the RadGridView inside of a Windows Forms ElementHost and have lost the ability to drag the column headers. I'm using Q1 2010 release. It worked great for us in Q3 2009 SP2. Any Suggestions for a work around would be great.

Thanks much

Hello,

I'm not sure if this is working as designed or a bug, but here is the issue.

We have a GridView hosted in a RadPane.  If the Pane is pinned, grouping works great.  If the pane is unpined, you can hover over it to expand the pane, but none of the grouping features work until you pin the pane again.

On a secondary note, I also noticed the sorting also get's lost when the pane is pinned and unpinned.

We are using the latest release 2010.2 812 of the controls.

Here is a quick sample on how we are using it:
