Question

I’m new to WPF/C#, and I’m trying to create a simple sql query application to get used to it. I have a listbox and a corresponding button in my XAML:

<ListBox Name="dbTables" Grid.Column="1" Grid.Row="2">
        <ListBoxItem>Log</ListBoxItem>
        <ListBoxItem>DownloadRequest</ListBoxItem>
        <ListBoxItem>EmailRequest</ListBoxItem>
    </ListBox>

    <!-- View report button -->
    <Button x:Name="myButton" Grid.Column="1" Grid.Row="3" Margin="0,10,0,0" Width="125" Height="25" HorizontalAlignment="Right" Click="Button_Click">View</Button>

and the corresponding C# function:

 private void Button_Click(object sender, RoutedEventArgs e)
    {
        String curItem = dbTables.SelectedValue.ToString();

        Console.WriteLine("CurItem = " + curItem);
        Results resultsPage = new Results(curItem);
        this.NavigationService.Navigate(resultsPage);

    }

However, when it outputs the CurItem it has this value:

CurItem = System.Windows.Controls.ListBoxItem: Log

Which then throws an exception when I try to run a SQL Query. I’m trying to get it to just be
CurItem = Log

I’ve tried several different ways but I can’t seem to just get the name of the selected value without the object definition attached.

The Selected Value is a ListBoxItem, so you can cast the value to ListBoxItem, and then use the Content property:

ListBoxItem selItem = (ListBoxItem)dbTables.SelectedValue;

        Console.WriteLine(selItem.Content);
