Oh dear. Now if only you'd talked to me beforehand, I'd have recommended against this book - I found it to be simply awful. I have huge respect for Juval, but this book keeps telling you to refer to things in other books that he's written, and that's not good in my mind.

Multiple Silverlight controls on an html/aspx page or multiple controls
on a single Silverlight page?

For the former, you should maybe post your question on a more appropriate board,
like Web Development[^].

For the latter, you could place controls "haffazard" by placing them on
a Canvas.

It looks like they're placed on a Canvas, as I mentioned.

WPF Control Name overwrite on initialization

NoviceUser0916-Mar-09 22:19

I am new to the world of WPF - so not sure how to do the below functionality. It will be great if someone can help me.

I have developed an app using WPF (XAML). What I am trying to do is during the start up time of the app, I am trying to read a file (.txt and xml) and I am trying to load the content for the controls from there. Those names will overwrite the default names for the controls given in the xaml files. I am loading the default names in xaml file from a resx file.
For example, one control is the name of the. In resx file, I stored "default user". Now every user should be able to display there name by simple adding a pre-defined tag "My_Name" and then providing there name in a .txt file. The app, on strat up, should load that string from the .txt file.
I found out a way to do it in the code - by reading the string from the file and assiging thet Control.Content = "Name_Read_From_File" - but I am trying to do it at the strat-up time by parsing the xaml file directly - so that I can restrict the functionality in one place. Many thanks in advance...

Why do you think this has something to do with WPF? Confused | :confused:

Write a method that loops over your collection and write the data to the excel file. Here[^].

The ListView in WPF is so different to the Forms one. Unsure | :~

Maybe the problem is how to iterate inside the ListView items.
Here it is:

GridView grid = source.View as GridView;
if (grid == null)
{
    //Sorry, only for GridView views
    return;
}
foreach (GridViewColumn col in grid.Columns)
{
    //value of header is col.Header
}
foreach (Object item in source.Items)
{
    PropertyInfo[] dataFields = item.GetType().GetProperties();
    int i = 0;
    foreach (GridViewColumn col in grid.Columns)
    {
        try
        {
            //Get the name of field displayed on grid
            string strPath = ((Binding)col.DisplayMemberBinding).Path.Path;
            //Get the field value
            object propValue = GetValue(item, source.Items, strPath);
            //Value of cell is propValue
        }
        catch (Exception)
        {
        }
    }
}

I think it will be easier to export (to excel, pdf or anything) from here.

I discourage the use of this method unless you really "really" have to put your class in a single xaml file. I can't even think of a scenario where you'd have to use this method.

I've just found out that you can place both the markup and the code in the xaml file.

<Window x:Class="WpfApplication1.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="Window1" Height="600" Width="300">
    <Grid>
        <Grid.Resources>
            <Style TargetType="{x:Type Button}">
                <Setter Property="Background" Value="Azure" />
            </Style>
        </Grid.Resources>

        <Grid.RowDefinitions>
            <RowDefinition />
            <RowDefinition Height="Auto" />
        </Grid.RowDefinitions>

        <Grid.Children>
            <StackPanel x:Name="stack" />
            <Button HorizontalAlignment="Center" Grid.Row="1" Content="Add button" Click="Button_Click" />
        </Grid.Children>
    </Grid>


    <x:Code>
        <![CDATA[
            public Window1()
            {
                InitializeComponent();
            }

            private void Button_Click(object sender, RoutedEventArgs e)
            {
                var button = new Button() { Content = "Newly added button" };
                var rnd = new Random(DateTime.Now.ToBinary().GetHashCode());
                
                switch (rnd.Next(3))
                {
                    case 0:
                        button.Background = Brushes.BlueViolet;
                        break;
                    case 1:
                        var style = new Style();
                        style.Setters.Add(new Setter(Button.BackgroundProperty, Brushes.DarkBlue));
                        button.Style = style;
                        break;
                }

                stack.Children.Add(button);
            }
        ]]>
    </x:Code>
</Window>

You don't have to place the code in a CDATA section. You even can do this.

<Window x:Class="WpfApplication1.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="Window1" Height="600" Width="300">
    <Grid>
        <Grid.Resources>
            <Style TargetType="{x:Type Button}">
                <Setter Property="Background" Value="Azure" />
            </Style>
        </Grid.Resources>

        <Grid.RowDefinitions>
            <RowDefinition />
            <RowDefinition Height="Auto" />
        </Grid.RowDefinitions>

        <Grid.Children>
            <StackPanel x:Name="stack" />

            <x:Code>
                public Window1()
            {
                InitializeComponent();
            }

            private void Button_Click(object sender, RoutedEventArgs e)
            {
                var button = new Button() { Content = "Newly added button" };
                var rnd = new Random(DateTime.Now.ToBinary().GetHashCode());
                
                switch (rnd.Next(3))
            </x:Code>

            <Button HorizontalAlignment="Center" Grid.Row="1" Content="Add button" Click="Button_Click" />
        </Grid.Children>
    </Grid>

    <x:Code>
                {
                    case 0:
                        button.Background = Brushes.BlueViolet;
                        break;
                    case 1:
                        var style = new Style();
                        style.Setters.Add(new Setter(Button.BackgroundProperty, Brushes.DarkBlue));
                        button.Style = style;
                        break;
                }

                stack.Children.Add(button);
            }
    </x:Code>
