Wrap Panel as ListView's item Panel - WrapPanel for ItemsControl

Wrap Panel wraps controls to new lines if no space is left. 

By default, the elements within a wrap panel are placed horizontally from left-to-right, top-to-bottom, but you can also place them vertically from top-to-bottom, left-to-right. Change the Orientation property for a wrap panel within the Properties panel under Layout. (MSDN)

The Orientation can be set to Vertical or Horizontal

Here, I am using a List<> (ItemsSource="{Binding reasonDTO}") for ListView Item Source , Bind the Text="{Binding ReasonDescription}" as Button Content .

<ListView

  ItemsSource="{Binding reasonDTO}"

  Name="ReasonListView"                     

  Height="auto" HorizontalAlignment="Stretch" MinWidth="600" Width="auto">

  <ListView.Resources>

<SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="Transparent"/>

       <SolidColorBrush x:Key="{x:Static SystemColors.HighlightTextBrushKey}" Color="DarkGreen"/>

 </ListView.Resources>

  <ListView.ItemsPanel>

                    <ItemsPanelTemplate>

                        <WrapPanel Width="{Binding (FrameworkElement.ActualWidth), RelativeSource={RelativeSource AncestorType=ScrollContentPresenter}}"

                                                               ItemWidth="{Binding (ListView.View).ItemWidth, RelativeSource={RelativeSource AncestorType=ListView}}"

                                                               MinWidth="{Binding ItemWidth, RelativeSource={RelativeSource Self}}"

                                                               ItemHeight="{Binding (ListView.View).ItemHeight, RelativeSource={RelativeSource AncestorType=ListView}}" />

                       

                    </ItemsPanelTemplate>

                </ListView.ItemsPanel>

                <ListView.ItemTemplate>

                    <DataTemplate>

                                             

                        <Button Width="250"

                                        Height="55"   

                                        MinWidth="150"

                                        Margin="5"

                                        Name="ReasonButton"

                                        Style="{StaticResource RoundButtonTemplate}"                                     

                                    Click="ReasonButton_Click">

                            <Button.Content>

                                <TextBlock Text="{Binding ReasonDescription}"  TextAlignment="Center" Padding="5" Width="200"  TextWrapping="Wrap"/>

                            </Button.Content>

                                                                               

                    </DataTemplate>

                </ListView.ItemTemplate>

               

            </ListView>
