Setting content dynamically

[Mrn]

Hello,

Is it possible to set the content of an Expander in code behind? For example, a certain grid or stackpanel with its own children controls... something like this:

<telerik:RadExpander Grid.Row="0" Header="{Binding Strings.Parameters, Source={StaticResource LocalizedStrings}}" Name="radExpanderParameters" Width="Auto" IsExpanded="True" >
                       <Grid Name="gridType" Grid.Row="0" Grid.Column="1" VerticalAlignment="Stretch" ShowGridLines="False">
                                <Grid.RowDefinitions>
                                    <RowDefinition Height="*" />
                                    <RowDefinition Height="2*" />
                                 </Grid.RowDefinitions>

                                <StackPanel Grid.Row="0" Margin="10" VerticalAlignment="Center">
                                    <RadioButton Margin="3" Content="Type 1" Height="16" GroupName="QueryType" x:Name="radioButton1"
                                                IsChecked="{Binding QueryType, Mode=TwoWay, ConverterParameter=current, Converter={StaticResource RadioButtonConverter}}" />
                                    <RadioButton Margin="3" Content="Type 2" Height="16" GroupName="QueryType" Name="radioButton2"
                                                IsChecked="{Binding QueryType, Mode=TwoWay, ConverterParameter=historical, Converter={StaticResource RadioButtonConverter}}" />
                                    <RadioButton Margin="3" Content="Type 3" Height="16" GroupName="QueryType" Name="radioButton3"
                                                IsChecked="{Binding QueryType, Mode=TwoWay, ConverterParameter=prediction, Converter={StaticResource RadioButtonConverter}}" />
                                   </StackPanel>

                                <StackPanel Grid.Row="1" Margin="10">
                                </StackPanel>

                        </Grid>
                    </telerik:RadExpander>

but I'd like to set the Grid in code behind instead.

Thanks in advance!

Hi Mrn,

Evrything that is possible is XAML is possible in code behind. The opposite is not true.
Your code from xaml should be similar to this C#:

private void BuildExpanderOnTheFly()
{
    RadExpander expander = new RadExpander();
    Grid grid = new Grid();
    grid.VerticalAlignment = VerticalAlignment.Stretch;
    grid.ShowGridLines = false;
    grid.RowDefinitions.Add(new RowDefinition() { Height = new GridLength(1, GridUnitType.Star) { } });
    grid.RowDefinitions.Add(new RowDefinition() { Height = new GridLength(2, GridUnitType.Star) { } });
    StackPanel panel = new StackPanel();
    RadRadioButton button = new RadRadioButton() { IsChecked = true, Content="Buuuuuton" };
    panel.Children.Add(button);
    grid.Children.Add(panel);
    expander.Content = grid;
    this.LayoutRoot.Children.Add(expander);
}

All the best,
