I'm using the MVVM pattern for my application.

 

Is it possible to bind the SortDescriptors collection of a RadGridView to a list in my viewmodel, and if so how do I do that?

 

Creating a property of type SortDescriptionCollection in my viewmodel is easy, but I don't know how to bind the gridview to that.

 

Thanks // David

Hi,

When I create one line series, the zoom and scroll work fine.
However, when I add more line series and try to zoom in, the series behave weird. Parts of the lines disappear and they don't actaully look like they're zoomed in.

Is there a limitation to implementing zoom on only one series? Or am I doing something wrong?


Thanks in advance.

I want the images to traverse in a liner path, like an image gallery.
How to define the path?

Hello, it's been hours since I've tried and searched for any samples that implements hierarchical data using Linq to SQL. It says in your feature product that it automatically detects hierarchy relationship. Could you please provide a tutorial on how to implement or bind a datacontext to the datatemplate of my hierarchychildtemplate? 

And, i currenty coded

void MainWindow_Loaded(object sender, RoutedEventArgs e)

        {

            

            m_dcData = new DataAccessDataContext();

            m_dcData.Log = Console.Out;

            rgvData.ItemsSource = m_dcData.Orders;

 

        }

And I tried to commenting out rgvData.ItemsSource = m_dcData.Orders and tried Binding the Linq to SQL class to xaml but I failed. How do I bind a Linq to SQL Class in xaml file so that in my second hierarchical data grid it shows the table that is related to the parent node?

<Grid>

        <Border telerikQuickStart:ThemeAwareBackgroundBehavior.IsEnabled="True" />

        <telerik:RadGridView x:Name="rgvData" CanUserFreezeColumns="False" GridLinesVisibility="Horizontal" ItemsSource="" IsReadOnly="True" AutoGenerateColumns="False">

            <telerik:RadGridView.ChildTableDefinitions>

                <telerik:GridViewTableDefinition />

            </telerik:RadGridView.ChildTableDefinitions>

            <telerik:RadGridView.Columns>

                <telerik:GridViewDataColumn DataMemberBinding="{Binding OrderDate}" Header="Order Date" />

                <telerik:GridViewDataColumn DataMemberBinding="{Binding EmployeeID}" Header="Employee" />

                <telerik:GridViewDataColumn DataMemberBinding="{Binding Freight}" />

                <telerik:GridViewDataColumn DataMemberBinding="{Binding ShipCountry}" Header="Ship Country" />

                <telerik:GridViewDataColumn DataMemberBinding="{Binding ShipCity}" Header="Ship City" />

            </telerik:RadGridView.Columns>

            <telerik:RadGridView.HierarchyChildTemplate>

                <DataTemplate>

                    <telerik:RadGridView x:Name="RadGridView1" CanUserFreezeColumns="False" AutoGenerateColumns="False" ShowGroupPanel="False" IsReadOnly="True">

                        <telerik:RadGridView.Columns>

                            <telerik:GridViewDataColumn DataMemberBinding="{Binding CustomerID}" Header="Customer ID" />

                            <telerik:GridViewDataColumn DataMemberBinding="{Binding Address}" Header="Address" />

                            <telerik:GridViewDataColumn DataMemberBinding="{Binding City}" Header="City" />

                            <telerik:GridViewDataColumn DataMemberBinding="{Binding Country}" Header="Country" />

                        </telerik:RadGridView.Columns>

                    </telerik:RadGridView>

                </DataTemplate>

            </telerik:RadGridView.HierarchyChildTemplate>

        </telerik:RadGridView>

    </Grid>

Thanks!

I have time series data that has gaps on holidays and weekends that must be omitted from the charts.  I am fine indexing the dates, that actually works good for me.  What I need to do is replace the index that is present on the X axis with the date it represents.  I have not found how to do this on the WPF charting controls.

Thanks!

Hi
I have a data table which contain round about 25 columns but i just want to show the 10 columns out of those in the RAD Carousel Control. Can you please guide me on how can i  achieve this functionality

Hi,
is it possible to have some kind of automatic page scrolling, so that the last added item is always visible?

I mean, while the software continues to add items, and the items reach the bottom of the grid, then you can't see the new items added unless you continuously scroll down *each new item added*!
The behaviour I want is that the grid automatic scroll down, letting the last item inserted to stay visible at the bottom of the page: is thi possible?

Thanks

Hi

when clicking on Automatic in the ColorPicker control included in my xaml as follows:

<telerik:RadColorPicker SelectedColorChanged="RadColorPicker_SelectedColorChanged" Tag="Foreground" Margin="5 0 5 0"/>

a System.NullReferenceException is thrown.

Sincerely.

I have a listbox that shows dates, when a user clicks on a specific date I want it to become editable. So when I click on the listbox item, a trigger switches its datatemplate from a template containing a textblock to a template containing a RadDatePicker.

When this occurs, the RadDatePicker immediatley updates the binding source with the value.  Why is this?  The WPF Toolkit date picker does not do this, but I'd have to use the RadDatePicker.

Because I am using entity framework self tracking entities, this immediatley marks the entity I've bound to as modified.

Does anyone know a way to stop the RadDatePicker updating the binding source as soon as it appears on a datatemplate?

I've recreated this problem in a test window.  The XAML looks like this:


... and the .cs looks like:


Thanks for any help!
Simon.
