 <ListView Name="CheckoutList" Margin="0,0,8,0">
  <ListView.View>
   <GridView x:Name="CheckOutGridView">
    <GridView.ColumnHeaderContainerStyle>
     <Style TargetType="{x:Type GridViewColumnHeader}">
      <Setter Property="Visibility" Value="Collapsed"/>
     </Style>
    </GridView.ColumnHeaderContainerStyle>
    <GridViewColumn>

      <DataTemplate>
       <TextBlock> 
        <Hyperlink >          
         <TextBlock Text="{Binding Path=Text}"/> 
        </Hyperlink> 
       </TextBlock>
      </DataTemplate>
     </GridViewColumn.CellTemplate>
    </GridViewColumn>
    <GridViewColumn>
     <GridViewColumn.CellTemplate>
      <DataTemplate>
       <TextBlock> 
        <Hyperlink>          
         <TextBlock Text="Remove"/> 
        </Hyperlink> 
       </TextBlock>
      </DataTemplate>
     </GridViewColumn.CellTemplate>
    </GridViewColumn>
   </GridView>
  </ListView.View>
 </ListView>

 <StackPanel Grid.Row="1">
  <Button Width="100" Height="25" Click="Button_Click" >name</Button>
  <Button Width="100" Height="25" Click="Button_Click1" >long name</Button>
 </StackPanel>
</Grid>

public partial class Window1 : Window
{
 class TextObject
 {
  private string _text;

  public TextObject(string Text)
  {
   _text = Text;
  }

  public string Text
  {
   get { return _text; }
   set { _text = value; }
  }
 }


 public Window1()
 {
  InitializeComponent();
 }

 private void Button_Click(object sender, RoutedEventArgs e)
 {
  CheckoutList.Items.Add(new TextObject("name"));
 }

 private void Button_Click1(object sender, RoutedEventArgs e)
 {
  CheckoutList.Items.Add(new TextObject("long name"));
 }

}

Given the above sample press name then long name. How come the column doesn't resize to fit its contents?

Answer 1

Try

<GridViewColumn Width="{x:Static System:Double.NaN}">

where

xmlns:System="clr-namespace:System;assembly=mscorlib"

and this should help you resize the column to fit the header content.
