Question

IEnumerable<string> peopleWithInvalidAge =
                    (from age in User
                     where age < 0
                     select name ).Distinct();

MessageBox.show("The people who have invalid age are {0}" , string.Join(", ", peopleWithInvalidAge) )

This displays the output as string . But what i want is that the output should be displayed in a tabular form . With Name and age when MessageBox.show is called.

If we can highlight inside message box then also it will be great

Please help.

Answer 1

This is for WPF

For formatting could use Window.
You can pass the IEnumerable in the ctor.
Window.ShowDialog is modal.

Window.ShowDialog Method

Window1 win = new Window1(new List<string> { "john", "susan" });
win.ShowDialog();

public Window1(IEnumerable<string> names)
{
    Names = names;
    InitializeComponent();
}
public IEnumerable<string> Names { get; private set; }

<Window x:Class="ListViewUpdate.Window1"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        DataContext="{Binding RelativeSource={RelativeSource self}}"
        Title="Window1" Height="300" Width="300">
<Grid>
    <ListView ItemsSource="{Binding Path=Names}" />
</Grid>
</Window>

Moderator there are three parts to question.
Modal, passing data, and formatting.
The other answer does not address modal or passing data to a Window.
I posted while I was creating the passing and formatting sample.
