Hi

I have a grid that starts off with no rows. The rows are created by adding to CriteriaColumnItem (see code snippet below).  When I a row the column in the new row shows the combobox column correctly.  However, when I add another row the new row shows the combobox correctly but the previous row now shows blank in the combobox column. 

Thanks
Rich

Guys,

I've the below requirement in Calender control.

• Highlight or circle the important days with different colors (eg. public holidays in one color and local holidays in a different color)
• Custom comments for the day should be shown in tool tip (eg. If I've applied leave for the upcoming day  it should be shown in some color (red) and if i place the mouse over it, the reason for the leave should show in tool tip)

 

Hi everyone,

I have an issue with selection of data from the RadGridView. The issue is that suddenly, after updating my Telerik Controls for WPF to 2013.1.220.40 it started hating my selection code.

I have the following XAML:

Which then triggers the following c# code when selecting a row:

However, when I select a row it the dgOrderOverview.SelectedItem is always null. If I look at it in the VS debugger I find that it says that SelectionEventArgs flags "remove" to the item I've selected, but the "added" is always null.

How come? This is new to me, it's been working since December before updating the RAD Controls for WPF.

I found exampale how to add toltip for each column, and it is working fine for me. I just wonder is there any way to define totlip once for whole row and bind with row data?

Hi all,

I have an application which is using RadTreeListView to bind and display as a tree. The ItemSource is binded from ViewModel with type is RadObservableCollection and declared:


The issue is when I add a new node to HistoryList then call RaisePropertyChange of HistoryList, the UI of RadTreeListView doesn't update even though the data added.


Then if I use reset() method of RadObservableCollection, the UI is updated but float top the top of view. So the question is how can I handle with it? I mean I wan to keep the state/position of node that I selected.. not jump or float.

This video gets better for you to understand: http://screencast.com/t/iLa3XWsa

Thank you

Hello,
I referred to a MVVM RadRibbonView example and I tried to implement RadRibbonComboBox in RibbonView with MVVM method.
But it doesn't work normally.
Please see a attached screenshot image.

I make a DataTemplate as follows.

Case1 -- use RadComboBox in RibbonView

    <!-- 
    <DataTemplate x:Key="ComboBoxItemTemplate">
        <Grid>
            <TextBlock Text="{Binding Text}" />
        </Grid>
    </DataTemplate>
    
    <DataTemplate x:Key="ComboBoxTemplate">
        <telerik:RadComboBox 
            ItemsSource="{Binding Items}" 
            ItemTemplate="{StaticResource ComboBoxItemTemplate}"
            SelectionBoxTemplate="{StaticResource ComboBoxItemTemplate}"
            SelectedIndex="{Binding SelectedIndex}"/>
    </DataTemplate>
    -->


Case 2. use RadRibbonComboBox and RadRibbonComboBoxItem 

    <DataTemplate x:Key="ComboBoxItemTemplate">
        <telerik:RadRibbonComboBoxItem Content="{Binding Text}" />
    </DataTemplate>

    <DataTemplate x:Key="ComboBoxTemplate">
        <telerik:RadRibbonComboBox 
            ItemsSource="{Binding Items}" 
            ItemTemplate="{StaticResource ComboBoxItemTemplate}"
            SelectedIndex="{Binding SelectedIndex}"/>
    </DataTemplate>

There appears to be a memory leak when a DocumentRuler is associated to a RadRichTextBox.  The following is code for a demo WPF Application project that can demonstrate this issue:

MainWindow.Xaml:

MainWindow.xaml.cs:

EditorView.xaml:

EditorView.xaml.cs:


The demo app has a button "New Editor" which will create a new usercontrol with a RadRichTextBox and associated DocumentRuler and add it to the main window.  If you keep pressing the New Editor button you will see that the memory usage of the application keeps growing.  Repeatedly creating new editors on my desktop caused the application memory usage to grow to over 4GB.

However, in EditorView.xaml, if you comment out the DocumentRuler declaration and repeat the test you will find that the memory usage of the application no longer grows unbound.  On my desktop the memory usage of the application after commenting out this line stayed under 400MB.

My desktop is running Win 7 x64, though this problem was observed on a number of different systems.

HI,

 I was wondering if it was possible to use a combination of properties in GroupDescriptor.

For example:

I have the data set: 

I would like to group by Name and Test and show the sum of the two parts (ordered by Name, then Test).

I recently had this working by adding a property to DummyModel that had both a Name and Test Properties and implemented IComparable and overwrote Equals and GetHashCode which allowed the grouping and sorting as I desired.I used this property as the Member property of the GroupDescriptor.

However this stopped working when we upgraded to v4.0.30319.

Any help on this issue would be greatly appreciated.

Thanks,

Steven

Hello,

I'm using a custom DragVisualProvider with the ListBoxDragDropBehavior and I can't seem to figure out how to offset the mouse position within the dragVisual. I know you can get the RelativeStartPoint from DragVisualProviderState, but how do you set that on the newly created dragVisual (ContentControl, in this case). 

Here is my custom DragVisualProvider code:

Hey there. I have a project with a RadMenu and it's menu Items are defined like so:


        <Style x:Key="MenuItemBaseStyle" TargetType="telerik:RadMenuItem">
            <Setter Property="Header" Value="{Binding Content}" />
            <Setter Property="IsSeparator" Value="{Binding IsSeparator}" />
            <Setter Property="ItemsSource" Value="{Binding}" />
        </Style>

        <Style x:Key="MenuItemLinkStyle" TargetType="telerik:RadMenuItem" BasedOn="{StaticResource MenuItemBaseStyle}">
            <Setter Property="Template" Value="{StaticResource MenuItemLinkControlTemplate}" />
            <Setter Property="Margin" Value="4 3 4 2" />
        </Style>

And the Template is defined:

        <ControlTemplate x:Key="MenuItemLinkControlTemplate" TargetType="telerik:RadMenuItem">
            <StackPanel>
                <Button Click="ButtonBase_OnClick" Content="{Binding Content}" Style="{StaticResource LinkButtonMenu}" />
            </StackPanel>
        </ControlTemplate>


I know it looks weird that It's a button, but there's a very specific reason we're doing that due to some issues we had after the last release. It was working fine prior to having to change it and I need it to work with the current Template I have defined for it. I tried setting the StaysOpenOnClick  property to false in the style as well and the issue still persisted. Thanks in advanced for the help.
