Hello!
Found one problem with radgridviev, which I dont know how to fix.

My scenario:

WPF app for .NET Framework 4
Windows 7 (x64) Ultimate
Version of Telerik dll's: 2011.1.419.40

Here's a structure of document that i'm querying from data source:
Client 
-- Animals
----- Receptions 
(there's other relations like Client - Contacts and so on...)

I show the data to user using the following hierarchy:

RadGridView (showing clients)
-- TabControl
----- RadGridView (showing animals)
---------- TabControl
--------------- RadGridView (showing receptions)


Now, for the problem:

Every RadGridView in hierarchy has handlers for: SelectionChanged, Deleted, RowEditEnded. 
When i add any of SelectionChanged, Deleted, RowEditEnded handler to receptions RadGridView my app shows only the clients grid (the topmost one) with "+" that's not expandable.
Without handlers everything (in leaf RadGridView) works as expected.
If i use a debugger it shows that i have exception: NullReferenceException that's throwed from GridViewRow.OnIsExpandedChanged.

Here's a part of xaml i use :

Any suggestions about what am i doing wrong?

EDIT: 

if i delete "RowStyleSelector="{StaticResource ReceptionRowStyleSelector}" and add handlers to my nested grid - then all seems to work again an there's no exception. But i have no row styling for grid.

That's my ReceptionRowStyleSelector code:


Styles i use a very simple:

<local:ReceptionRowStyleSelector x:Key="ReceptionRowStyleSelector">
            <local:ReceptionRowStyleSelector.DefaultStyle>
                <Style TargetType="telerik:GridViewRow"></Style>
            </local:ReceptionRowStyleSelector.DefaultStyle>
            <local:ReceptionRowStyleSelector.CompletedReception>
                <Style TargetType="telerik:GridViewRow">
                    <Setter Property="Background" Value="#4502FF49"/>
                </Style>
            </local:ReceptionRowStyleSelector.CompletedReception>
            <local:ReceptionRowStyleSelector.CanceledReception>
                <Style TargetType="telerik:GridViewRow">
                    <Setter Property="Background" Value="#40000000"/>                
                </Style>
            </local:ReceptionRowStyleSelector.CanceledReception>
            <local:ReceptionRowStyleSelector.NotifiedReception>
                <Style TargetType="telerik:GridViewRow">
                    <Setter Property="Background" Value="#4FA4B700"/>
                </Style>
            </local:ReceptionRowStyleSelector.NotifiedReception>
        </local:ReceptionRowStyleSelector>

How can I programmatically change the ConvertParameter in those TextBlocks and also change the Colorizer ExtendedPropertyName? I can't seem to figure out how to get to them.

Hi,

If a user double clicks on any element in the RadGridView the RowActivated event fires... This is especially annoying as you double click the text box in the filter options to select all text in the textbox (standard windows things) but this triggers the event.

Thanks,

Is it possible to have a multiple column GridViewComboBoxColumn where the dropdown shows multiple columns - almost like another grid?

I've got a dropdown that concatenates 3 data points and it would be cool if the dropdown rendered a mini-grid of values instead of a list of concatenated string values.  Even cooler would be sorting and filtering within the min-grid...

I'm trying to get a handle to the Grouping Event but I'm not having any luck.
Please Help.

I have a WPF application which calls a dialog using the ShowDialog method and then sets the e.NewObject of the GridView event to the newly created row. Everything works very well, however I am attempting to change the ShowDialog calls to remove the synchronous actions. This is to get the code working in an XBap environment and to get it closer to Silverlight if a port is needed.

I am however baffled as to how to do this without blocking the UI thread to wait for the dialog information.

This is basically what I am doing now:


This is what I would like to do

Hi. I'm using the WPF RadTreeListView with EnableRowVirtualization = false and EnableColumnVirtualization = false. I hook the TreeListViewRow's IsExpandedChanged event and, in the handler, I go through all the RadTreeListView's Items. Ultimately, I want to get the item containers (the TreeListViewRows) for each item.

But when an row is collapsed (as opposed to expanded) all its child items disappear from RadTreeListView's Items collection! When I expand the row, the child items come back.

Even if virtualization were on, that should only affect the existance of TreeListViewRows, not the existence of Items. How do I fix this?

Thanks,

I have implemented a class that inherits from the ScheduleView.Appointment class. The only thing that I added to this class is a constructor and 2 properties (Start & End).

When I drag an appointment within the ScheduleView, the Start and End properties (that overload the base class's Start and End properties) are not modified....the break points are never hit.

Since the class that inherits from ScheduleView.Appointment is also going to be wrapping my Model's "Appointment" class...I would really appreciate someone telling me how to get the GUI to update the Start and End properties when you drag the Appointment's start/end points to a new time value.

This is my very very simple appointment class...the start and end properties are never set when I drag an appointment in the ScheduleView:



Thanks for your time and help!

Let me explain the scenario:

In a WPF-Window i have a grid with one row and three columns. The columns are used as follow:
Column 0 => RadDocking
Column 1 => GridSplitter
Column 2 => A ContentControl

When moving the gridsplitter, the raddocking will be resized well. But:

The RadDocking contains for example two panes. If i minimize the panes, they are shown on the left site - as expected. But the GridSplitter did not "follow to the left".

Okay - the RadDocking is "working" in the area defined by grid column 0 and may be it did not know anything about other controls in the grid that must be resized if all panes in a raddocking are minimzed. Is there a solution?

I have a small example app that shows the problem at runtime - below the xaml of the window.

I'm trying to have the Legend lay on top of the chart area. To my understanding the following code should work. I am setting my data in codebehind. If I change the value of UseDefaultLayout to True the chart control displays the correct chart by using the default ChartArea and default ChartLegend etc. However, when I set UseDefaultLayout to False, like in the code below, the ChartArea displays the error No Series Data. The ChartLegend is located at the desired location so I need to know why my data is not being displayed. Please help me understand why this is not working and how to fix it.

<DataTemplate x:Key="ChartDataTemplate"> 

    <telerik:RadChart x:Name="Chart" UseDefaultLayout="False"> 

        <Grid> 

            <Grid.RowDefinitions> 

                <RowDefinition Height="1*" /> 

                <RowDefinition Height="19*" /> 

            </Grid.RowDefinitions> 

            <Grid.ColumnDefinitions> 

                <ColumnDefinition Width="19*" /> 

                <ColumnDefinition Width="1*" /> 

            </Grid.ColumnDefinitions> 

            <telerik:ChartLegend x:Name="LegendArea"

                                 Grid.Row="1"

                                 Grid.Column="0"

                                 HorizontalAlignment="Right"

                                 VerticalAlignment="Top" /> 

            <telerik:ChartArea LegendName="LegendArea" /> 

        </Grid> 

    </telerik:RadChart> 

</DataTemplate>

Thank you,
Danny
