Question

I have the following templete

<ControlTemplate x:Key="tmpl_btn_TecnicianModeMenu" TargetType="{x:Type ListBoxItem}">
<Grid Opacity="1" d:LayoutOverrides="Width, Height">
    <Border 
        x:Name="Border"  
        CornerRadius="0" 
        BorderThickness="0" Height="Auto" Margin="0" Background="White">

        <StackPanel Name="stackPanel" Height="Auto" Margin="0" Orientation="Horizontal" >
            <Button x:Name="button" Style="{DynamicResource ButtonListBoxItem}" Margin="5,5,5,5" Width="120" Height="Auto" BorderThickness="0" >
                <TextBlock x:Name="textBlock" TextWrapping="Wrap" Text="בצע"  Margin="12,0" VerticalAlignment="Center" HorizontalAlignment="Stretch" Style="{DynamicResource tb_Desc}"/>
            </Button>

** I have list box of such items. I want to bind it to an observable list. the problem is that the previus programer added items to the list like this:**

  private void AddButtonToList(String LB_CheckName, String LB_Date, String LB_TchName, String LB_OK, String LB_Result, enmTechMode_Check enmCheck )
    {
        try
        {
            //create item
            ListBoxItem item2 = new ListBoxItem();
            //set template
            item2.SetResourceReference(ListBoxItem.TemplateProperty, "tmpl_btn_TecnicianModeMenu");
            item2.ApplyTemplate();

            item2.Height = 45;

            TextBlock txt1 = (TextBlock)item2.Template.FindName("LB_CheckName", item2); 
            txt1.Text = LB_CheckName;

            txt1 = (TextBlock)item2.Template.FindName("LB_Date", item2); 
            txt1.Text = LB_Date;

            txt1 = (TextBlock)item2.Template.FindName("LB_TchName", item2);  
            txt1.Text = LB_TchName;

            txt1 = (TextBlock)item2.Template.FindName("LB_OK", item2);   
            txt1.Text = LB_OK;

            txt1 = (TextBlock)item2.Template.FindName("LB_Result", item2);   
            txt1.Text = LB_Result;

            Button bt = (Button)item2.Template.FindName("button", item2);
            bt.SetResourceReference(Button.StyleProperty, "ButtonListBoxItem");
            bt.ApplyTemplate();

            bt.Click += new RoutedEventHandler(Item_Selected);
            //set tag
            bt.Tag = enmCheck;

            //add to list
            StackPanel sp = (StackPanel)ListBoxData.FindName("stackPanel");
            item2.Tag = enmCheck;
            sp.Children.Add(item2);

        }
        catch (Exception exp)
        {
         }
    }

and I have no clue how to fix this

I assume theres suppose to be a use of a convertor? please provide me a direction

I assume the observable list suppose to be of structs. but how convert those to items in the temples format?

Answer 1

In a template you would usually bind to properties of the data object. If for example you have the data class below with a Result property

public class MyData
{
    public string Result { get; set; }
    ...
}

you would bind like this:

<TextBlock Text="{Binding Path=Result}" ... />

Then you would not manually add ListBoxItems, but instead add data objects to the ObservableCollection, that the ItemsSource property of the ListBox is bound to:

myDataObjects.Add(
    new MyData
    {
        Result = "A Result"
        ...
    });

where myDataObjects is an ObservableCollection<MyData> .

In case you would need to get the UI updated when a data object changes which is already contained in the ObservableCollection, class MyData would need to implement INotifyPropertyChanged .
