I have a WPF app which has a grid with 2 columns set to * and auto. The issue is when I reduce the size of the window the children in second column are getting clipped from right instead of left. I expect them to clip from left because I have set the horizontal alignment to right. Is there a way we can clip the second column elements from left?

Auto means that a column is given as much width as the elements within it require. The width of * sized columns is calculated by allocating space for the Auto , and fixed width columns, and then dividing up the remaining space.
WPF GridSplitter control is a divider that helps to split the available space into rows and columns in a grid. It supports to splits the controls horizontally or vertically with a splitter. In addition to that, it allows users to resize the grid's column width and row height on demand.
A Grid Panel provides a flexible area which consists of rows and columns. In a Grid, child elements can be arranged in tabular form. Elements can be added to any specific row and column by using Grid.Row and Grid.Column properties. By default, a Grid panel is created with one row and one column.
A Grid is a very powerful and useful Layout in WPF. It enables you to arrange children elements in cells defined by rows and columns. In fact, when we add a new XAML document or create a new WPF Project in Visual Studio, Visual Studio automatically adds a Grid as the first container inside the window element.
Instead of this:
<Window x:Class="WpfApp2.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:local="clr-namespace:WpfApp2"
mc:Ignorable="d"
Title="MainWindow" Height="450" Width="800" >
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" MinWidth="60"/>
<ColumnDefinition Width="auto"/>
</Grid.ColumnDefinitions>
<DockPanel HorizontalAlignment="Right" Grid.Column="1">
<Button Click="Button_Click" Content="click me" Width="150" DockPanel.Dock="Right" />
<Label Content="abcdef" Width="200" DockPanel.Dock="Right" />
<Label x:Name="mLog"/>
</DockPanel>
<Button Click="Button_Click" DockPanel.Dock="Right" Content="click me" Width="150"/>
<Label Content="abcdef" Width="200" DockPanel.Dock="Right"/>
</Grid>
</Window>
try this:
<Window x:Class="WpfApp2.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:local="clr-namespace:WpfApp2"
mc:Ignorable="d"
Title="MainWindow" Height="450" Width="800" >
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" MinWidth="60"/>
<ColumnDefinition Width="auto"/>
</Grid.ColumnDefinitions>
<DockPanel HorizontalAlignment="Right" Grid.Column="1">
<Button Click="Button_Click" Content="click me" Width="150" DockPanel.Dock="Right" />
<Label Content="abcdef" Width="200" DockPanel.Dock="Right" />
<Label x:Name="mLog"/>
</DockPanel>
<Button Click="Button_Click" DockPanel.Dock="Right" Content="click me"/>
<Label Content="abcdef" Width="200" DockPanel.Dock="Right"/>
</Grid>
</Window>
i deleted the last button width property.
output:
190
I would guess you are trying to make 3 column layout with 1 button on either side and 1 middle lane for content.
So you could try something like this, where all your content are in same grid with different z-index and horizontal alignments, now when you resize the window the label stays in middle and the buttons "clip behind" the label content from the right and the left.
<Grid>
<Button HorizontalAlignment="Left" Content="click me" Width="150" />
<Button HorizontalAlignment="Right" Content="click me" Width="150" />
<Label HorizontalAlignment="Center" Content="abcdef" Width="200" Background="White" />
</Grid>
