Radcombox within a datatemplate not binding

[peter]

Hi I have an datatemplate which i have created for my raddataform, the problem i am getting is that within the datatemplate i have a radcombobox, and when loaded i want the selected value to be bound to the value form a radgridview, which is outside of the datatemplate. However this doesnt work. Here is what the datatemplate looks like;

             <DataTemplate x:Key="eventHeaderEditTemplate"  >
                    <Grid>
                        <Grid.RowDefinitions>
                            <RowDefinition Height="Auto"/>
                        </Grid.RowDefinitions>
                        <Grid Margin="8,8,0,0" d:LayoutOverrides="Height">
                            <Grid.ColumnDefinitions>
                                <ColumnDefinition Width="150" />
                                <ColumnDefinition Width="*" />
                            </Grid.ColumnDefinitions>
                            <Grid.RowDefinitions>
                                <RowDefinition />
                                <RowDefinition />
                                <RowDefinition />
                                <RowDefinition />
                                <RowDefinition />
                                <RowDefinition />
                                <RowDefinition />
                                <RowDefinition />
                                <RowDefinition />
                            </Grid.RowDefinitions>
                                           <TextBox x:Name="txtEventStateID" Text="{Binding SelectedItem.EventHeader.EventStateID, ElementName=staticDataRadGrid}" TextWrapping="Wrap" FontFamily="Segoe UI" FontSize="14" Foreground="{StaticResource StrongBrush}" Grid.Column="1" Grid.Row="6"  Margin="0,0,0,2" />

                            <Telerik:RadComboBox ItemsSource="{Binding EventStateDTOs,Source={StaticResource EventStateDTOViewModel},Mode=TwoWay}"    x:Name="comboBoxEventState"
Grid.Column="1" SelectedValue="{Binding SelectedItem.EventHeader.EventStateID, ElementName=staticDataRadGrid}"   Style="{StaticResource RadComboBoxStyle}" FontFamily="Segoe UI Light"  FontSize="24" Margin="0,0,0,2" Grid.Row="7" VerticalAlignment="Bottom" Height="40">
                                <i:Interaction.Triggers>
                                    <i:EventTrigger EventName="Loaded">
                                        <cmd:EventToCommand Command="{Binding ExecuteCommand, Source={StaticResource EventStateDTOViewModel}}" CommandParameter="geteventstates"></cmd:EventToCommand>
                                    </i:EventTrigger>
                                </i:Interaction.Triggers>
                                <Telerik:RadComboBox.ItemTemplate>
                                    <DataTemplate>
                                        <TextBlock Text="{Binding Name}"  Foreground="{StaticResource MainBrush}" />
                                    </DataTemplate>
                              </Telerik:RadComboBox.ItemTemplate>
                           </Telerik:RadComboBox>
                        </Grid>
                    </Grid>
                </DataTemplate>

Hi,

I would suggest you to use the SelectedItem together with SelectedValuePath to accomplish this. Here is sample code:

<Telerik:RadComboBox ItemsSource="{Binding EventStateDTOs,Source={StaticResource EventStateDTOViewModel},Mode=TwoWay}"
              x:Name="comboBoxEventState"
              SelectedItem="{Binding SelectedItem., ElementName=staticDataRadGrid}"
              SelectedValuePath="EventHeader.EventStateID" ...  />

I hope this helps you.

All the best, Ivo
