RadComboBox refrencing a RadGridView

[Martin Egger]

First of all I wanna say that I just started learning C# and XAML. I got very interested in the use of the Rad Controls and had some problems to implement a RadComboBox which refrences the selected Item in a RadGridView.

My goal is to develop a Master Detail View which uses the RadGridView for selection and a form with comboboxes and textboxes.

I am using Entity Framework and .Net 3.5

Here is my XAML Sourcecode:

    <DockPanel>
        <Grid DockPanel.Dock="Top" >
            <Grid.ColumnDefinitions>

            </Grid.ColumnDefinitions>
            <Grid.RowDefinitions>
                <RowDefinition />
                <RowDefinition />
            </Grid.RowDefinitions>
            <StackPanel Grid.Row="0" x:Name="PlattenDetail" DataContext="{Binding Source={StaticResource PlattenView}}">

                 <telerik:TextBoxEditor Text="{Binding ElementName=radGridView1, Path=SelectedItem.platteID}"></telerik:TextBoxEditor>
                 <telerik:RadComboBox x:Name="CBLieferant" >

                </telerik:RadComboBox>



            </StackPanel>

            <telerik:RadGridView Grid.Row="1"  Name="radGridView1" ItemsSource="{Binding Source={StaticResource PlattenView}}" AutoGenerateColumns="False" Height="582" Margin="-8,0,0,-198"
                               >
                <telerik:RadGridView.Columns>
                    <telerik:GridViewDataColumn Header="ID" DataMemberBinding="{Binding platteID}" />
                    <telerik:GridViewDataColumn Header="Lieferant" DataMemberBinding="{Binding Path=preise.lieferant.lieferantName1}" />
                </telerik:RadGridView.Columns>




            </telerik:RadGridView>

        </Grid>

    </DockPanel>

As you can see I didn't populate the ComboBox with any properties. I did this because I just did alot of trial and error with SelectedItem SelectedValue(Path) and so on and never came to a result like it worked for the textbox.

Hopefully you can help me with this issue.

Well I don't know if I am stupid for the last few weeks. I was trying everthing until today I realised that I am working with a RadGridView as a Master and TextBoxes and Comboboxes as Detail.

I don't know why I always was thinking that I was working with a ListView as a Master. Therefore always looking for does documentations. In the end I solved my problem partially with SelectionChange Event.

Though I am not finished yet I will provide my solution in the next few days.

Thx anyway.

UPDATE

Following Problem.
When a differtent Item is selected within the RadGridView it changes the values in the detailview.

private void radGridView1_SelectionChanged(object sender,SelectionChangeEventArgs e)
        {
            Platten platten = this.radGridView1.SelectedItem as Platten;
            txtBoxEditorPlattenNummer.Text = platten.plattenNummer;
            txtBoxEditorPlattenName1.Text = platten.plattenName1;
}

When I do the same for the Comboboxes it won't work.

CDM.DataAccessLayer.Style style = this.radGridView1.SelectedItem as CDM.DataAccessLayer.Style;

            radComboBoxStyle.Text = style.stylName;

When I use "Jazz" instead of style.stylName it works perfectly.

Thx.

comboBoxLieferanten.SetValue(RadComboBox.TextProperty, (platten.preis.lieferant.lieferantName1));
                comboBoxStyle.SetValue(RadComboBox.TextProperty, (platten.styl.stylName));
                comboBoxPreise.SetValue(RadComboBox.TextProperty, (platten.preis.plCode));

I solved my problem. Managed it with the SelectionChanged Event of the RadGridView.
