I've created some UserControls which are wrapping some standard controls, for example: a textbox/combobox + Image + textblock. I'm trying to do the same thing with AutoCompleteBox and have failed so far...
The list of items is shown fine, I can select na item, but that doesn't trigger a change to the SelectedItem. I'm using almost the same code for combobox so not sure what's wrong...
Anyway I've played around with ValueMemberPath / ValueMemberBinding on the AutoCompleteBox but not sure if that's the way to go.
The UserControl xaml:
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="3*" />
</Grid.ColumnDefinitions>
<Grid Grid.Column="0" Margin="0,0,2,0">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Image Source="{Binding ElementName=ACProperty, Path=ImageSource}" VerticalAlignment="Center"
MaxHeight="30" MaxWidth="30" Margin="1" Grid.Column="0" RenderOptions.BitmapScalingMode="HighQuality"/>
<TextBlock Text="{Binding ElementName=ACProperty, Path=Label}" VerticalAlignment="Center"
HorizontalAlignment="Left" Grid.Column="1" Margin="1" TextWrapping="Wrap" Width="100" />
</Grid>
<toolkitInput:AutoCompleteBox FilterMode="ContainsOrdinal" IsTextCompletionEnabled="True"
ItemsSource="{Binding ElementName=ACProperty, Path=ItemsSource}"
SelectedItem="{Binding ElementName=ACProperty, Path=SelectedItem}"
MinimumPrefixLength="2"
MinimumPopulateDelay="300"
VerticalAlignment="Center"
HorizontalAlignment="Stretch" Grid.Column="1" Margin="1,1,2,1" />
</Grid>
The code behind:
public static DependencyProperty LabelProperty = DependencyProperty.Register(
"Label", typeof(string), typeof(AutoCompleteProperty));
public static readonly DependencyProperty ItemsSourceProperty =
DependencyProperty.Register("ItemsSource", typeof(object), typeof(AutoCompleteProperty));
public static readonly DependencyProperty SelectedItemProperty =
DependencyProperty.Register("SelectedItem", typeof(object), typeof(AutoCompleteProperty),
new FrameworkPropertyMetadata() { BindsTwoWayByDefault = true });
public static DependencyProperty ImageSourceProperty = DependencyProperty.Register(
"ImageSource", typeof(string), typeof(AutoCompleteProperty));
public object ItemsSource
{
get
{
return (object)GetValue(ItemsSourceProperty);
}
set
{
SetValue(ItemsSourceProperty, value);
}
}
public object SelectedItem
{
get
{
return (object)GetValue(SelectedItemProperty);
}
set
{
SetValue(SelectedItemProperty, value);
}
}
public string Label
{
get
{
return (string)GetValue(LabelProperty);
}
set
{
SetValue(LabelProperty, value);
}
}
public string ImageSource
{
get
{
return (string)GetValue(ImageSourceProperty);
}
set
{
SetValue(ImageSourceProperty, value);
}
}
And in a UserControl/Window where I would like to use it:
<cont:AutoCompleteProperty Label="Product Category"
ItemsSource="{Binding Path=ProductCategories}"
SelectedItem="{Binding Path=ProductCategory}"
ImageSource="..."/>
I have updated binding in the following code....

I have create simple drag drop in WPF. In my application there are two Listviews. I have to drag list items from first listview and drop the item to second listview. I have created custom data template for first listview. When i drag the first listview item into second listview the data template is not customized so items are not displayed. How to display the list items with generic. Please help. My Code is as below,
<Grid Margin="0,20,0,0">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>
<ListBox
Name="memberCollection"
Grid.Column="1"
Width="150"
HorizontalAlignment="Stretch"
VerticalAlignment="Stretch"
PreviewMouseLeftButtonDown="memberCollection_PreviewMouseLeftButtonDown">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel>
<TextBox Text="{Binding Name}" />
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
<Grid
Name="gridDrop"
Grid.Column="0"
Margin="20,0,0,0"
HorizontalAlignment="Stretch"
VerticalAlignment="Stretch"
ListBox.Drop="grid_Drop"
ShowGridLines="True">
<ListBox
Grid.Row="0"
Grid.Column="0"
Margin="10,10,0,0"
AllowDrop="True" />
</Grid>
</Grid>
Code Behind
ObservableCollection<Member> member = new ObservableCollection<Member>();
public MainWindow()
{
InitializeComponent();
member.Add(new Member { Name = "Karthick", ID = "20011", Address = "10, MainRoad, Chennai" });
memberCollection.ItemsSource = member;
DataContext = new Member();
}
private void memberCollection_PreviewMouseLeftButtonDown(object sender, MouseButtonEventArgs e)
{
object selectedMember = memberCollection.SelectedItem as Member;
if (selectedMember != null)
DragDrop.DoDragDrop(memberCollection, selectedMember, DragDropEffects.All);
}
private void grid_Drop(object sender, RoutedEventArgs e)
{
ListBox listContent = e.Source as ListBox;
if (listContent != null)
Console.WriteLine("", Grid.GetColumn(listContent), Grid.GetRow(listContent));
DataObject item = (((DragEventArgs)e).Data) as DataObject;
object Target = ((Grid)(sender)).DataContext;
object listItem = item.GetData(Target.GetType());
if (listItem != null)
{
//listContent.Items.Add(listItem.Name.ToString());
//listContent.Items.Add(listItem.ID.ToString());
//listContent.Items.Add(listItem.Address.ToString());
//listContent.ItemTemplate = memberCollection.ItemTemplate;
listContent.Items.Add(listItem);
}
}
If you define the DataTemplate as a reusable resource, you can use it in both ListBoxes:
<Grid Margin="0,20,0,0">
<Grid.Resources>
<DataTemplate x:Key="dataTemplate">
<StackPanel>
<TextBox Text="{Binding Name}" />
</StackPanel>
</DataTemplate>
</Grid.Resources>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>
<ListBox
Name="memberCollection"
Grid.Column="1"
Width="150"
HorizontalAlignment="Stretch"
VerticalAlignment="Stretch"
PreviewMouseLeftButtonDown="memberCollection_PreviewMouseLeftButtonDown"
ItemTemplate="{StaticResource dataTemplate}" />
<Grid
Name="gridDrop"
Grid.Column="0"
Margin="20,0,0,0"
HorizontalAlignment="Stretch"
VerticalAlignment="Stretch"
ListBox.Drop="grid_Drop"
ShowGridLines="True">
<ListBox
Grid.Row="0"
Grid.Column="0"
Margin="10,10,0,0"
AllowDrop="True"
ItemTemplate="{StaticResource dataTemplate}"/>
</Grid>
</Grid>
If you want to display some other properties of the dropped Member in the second ListBox, you should define another ItemTemplate:
<ListBox
Grid.Row="0"
Grid.Column="0"
Margin="10,10,0,0"
AllowDrop="True">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel>
<TextBlock Text="{Binding Name}" />
<TextBlock Text="{Binding Id}" />
<TextBlock Tag="{Binding Address}" />
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
I have a data input form where i have textboxes,comboboxes and datepickers. I want to Bind comboboxes to the DB column so that users select the correct value for insertion. I have attached the viewmodel class and XAML code. In the viewmodel code "private void GetSW()" - this gets all the list of the entity class and "private void addSW()" this adds the record to the DB, Except the combobox binding everything works fine. in XAML i have binded combobox like this but this give blank combobox, please help what i am missing. I researched many topics on this forum but didn't find any solution
<ComboBox x:Name="PSW" Grid.Column="3" Grid.Row="2" ItemsSource="{Binding newSW.PreviousSW}" HorizontalAlignment="Left" VerticalAlignment="Top" Width="100" Height="20"/>

I guess you want to display the list of SoftwareDefEntity objects in your ComboBox.
Bind to the SWentities property then:
<ComboBox x:Name="PSW" Grid.Column="3" Grid.Row="2" ItemsSource="{Binding SWentities}" DisplayMemberPath="Name" ... />
And raise the PropertyChanged event in its setter of this property:
private List<SoftwareDefEntity> _swEntities;
public List<SoftwareDefEntity> SWentities
{
get { return _swEntities; }
set { _swEntities = value; RaisePropertyChanged(); }
}
This is the code to bind the data to combobox. i did not add any of other controls since those are working fine at your place. Observable collection is easy way to bind combobox .
Here is your View Model..
public class SoftwareVersionListViewModel : ViewModelBase
{
public SoftwareVersionListViewModel()
{
GetSW();
}
//Define the observable collection
private ObservableCollection<SoftwareDefEntity> _SWmappings2 = new ObservableCollection<SoftwareDefEntity>();
//here is your Entity list
public List<SoftwareDefEntity> SWentities
{
get;
set;
}
// Obeservable collection property for access
public ObservableCollection<SoftwareDefEntity> SWmappings2
{
get { return _SWmappings2; }
set
{
_SWmappings2 = value;
OnPropertyChanged("appeventmappings2");
}
}
/// <summary>
/// load the combobox
/// </summary>
private void GetSW() // Method that reads the data from the service layer
{
SWDefService obj = new SWDefService();
SWentities = obj.getSW(); //getSW is the method refered in Service layer
SWentities.ForEach(_SWmappings2.Add);
}
}
and Xaml...
<ComboBox x:Name="ComboBox" ItemsSource="{Binding SWmappings2, UpdateSourceTrigger=PropertyChanged}" DisplayMemberPath="PreviousSW" SelectedItem="{Binding PreviousSW, Mode=TwoWay}" Grid.Row="0" >
</ComboBox>
My itemscontrol is currently loading each row correctly. I am trying to get it to change the background color of each row when the user selects it.

Which currently looks like this:
I tried adding a DataTemplate.Triggers but it doesn't seam to do anything. How exactly do you detect that a row in a itemscontrol has been selected? The only examples I have found use a datagrid. I tried changing mine to a datagrid instead of the itemscontrol, but then the it wouldn't load the data.
Datagrid:
<DataGrid x:Name="grd" Background="White" DataContext="{Binding DatabaseServers}" Grid.Row="2">
<Image Source="{Binding StatusImage}" Height="10" Width="10" />
<Label Grid.Column="1" HorizontalAlignment="Left" Content="{Binding ServerName}" />
<Label Grid.Column="2" HorizontalAlignment="Left" Content="{Binding SourceDatabase}" />
<TextBox x:Name="dst" Grid.Column="3" Text="{Binding DestinationDatabase , Mode=TwoWay, UpdateSourceTrigger=LostFocus}" VerticalAlignment="Top" />
<Label Grid.Column="4" Content="{Binding Status}" VerticalAlignment="Top" />
<Button Grid.Column="4" BorderThickness="0" HorizontalAlignment="Center" Width="50" Margin="3" Content="{Binding Status}" Command="{Binding EnabledCommand}" CommandParameter="{Binding}" />
</DataGrid>
Just shows a bunch of lines there is no data in each row.
I am very new to WPF so I cant really figure out what I am doing wrong here.

And This is My C# Code :-
public Dictionary<string, bool> DictTemperature { set; get; }
DictTemperature = new Dictionary<string, bool>();
if (!appSettings.Contains("AppTemperature"))
{
DictTemperature.Add("Celsius", true);
DictTemperature.Add("Fahrenheit", true);
DictTemperature.Add("Kelvin", true);
DictTemperature.Add("Rankine", true);
appSettings.Add("AppTemperature", DictTemperature);
}
DictTemperature = (Dictionary<string, bool>)appSettings["AppTemperature"];
here listbox is showing count as 4 and showing the key value pairs also but unable to bind key with the textblock.
Please tell me the solution....
You can do it Shown here (Binding a Dictionary's key and value in a listbox with wpf)
For some reason using Content="{Binding Time, StringFormat=t} is still giving me a long date. The backing field is a DateTime property initialised with DateTime.Now but no matter what string format I try it still shows the full date...
I would like only to see HH:mm tt
Any ideas?

StringFormat works on properties of type string. The Content property is of type Object so you need to specify the format using ContentStringFormat property of Label control.
<Label Content="{Binding Time}" ContentStringFormat="t" VerticalContentAlignment="Center" Foreground="IndianRed" FontSize="36" Grid.Column="0" />
