I have a DataTemplate like this:
<DataTemplate x:Key="CheckBoxDataTemplate">
<CheckBox IsChecked="{Binding
Path=IsSelected, Mode=TwoWay}"
HorizontalAlignment="Center"
VerticalAlignment="Center" Name="aDM_LEVEL_FIELDListView" Path="SelectedItem">
<i:Interaction.Triggers>
<i:EventTrigger EventName="Checked">
<WPFCtlr:EventToCommand Command="{Binding DataContext.UnCheckCommand, RelativeSource={RelativeSource FindAncestor,ListView,1}}" CommandParameter="{Binding ElementName=_thisChk}" />
<!--<i:InvokeCommandAction Command="{Binding Path=SelectItemRelayCommand}" />-->
</i:EventTrigger>
</i:Interaction.Triggers>
</CheckBox>
<!--Command="{Binding Path=DataContext.UnCheckCommand}"
CommandParameter="{Binding Path=IsChecked, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type UserControl}}}" />-->
</DataTemplate>
This is the templateSelector:
<TemplateSelector:PropertyDataTemplateSelector x:Key="templateSelector"
BooleanDataTemplate="{StaticResource CheckBoxDataTemplate}"
IsEnum="IsExclusive"/>
And this is the ListView where the template is referenced:
<ListView Grid.Row="1"
ItemsSource="{Binding Path=FilteredLevelFields}"
Margin="5,10,5,5"
Name="aDM_LEVEL_FIELDListView"
SelectionMode="Single"
FontSize="13"
Background="AliceBlue"
BorderBrush="AliceBlue"
SelectedItem="{Binding Path=CurrentElement}">
<!--Style of items-->
<ListView.ItemContainerStyle>
<Style TargetType="{x:Type ListViewItem}">
<!--Properties-->
<Setter Property="Control.HorizontalContentAlignment" Value="Stretch" />
<Setter Property="Control.VerticalContentAlignment" Value="Center" />
<!--Trigger-->
<Style.Triggers>
<Trigger Property="IsSelected" Value="True">
<Setter Property="Background" Value="{x:Null}" />
<Setter Property="BorderBrush" Value="{x:Null}" />
</Trigger>
</Style.Triggers>
</Style>
</ListView.ItemContainerStyle>
<ListView.View>
<GridView ColumnHeaderContainerStyle="{StaticResource GridViewColumnHiddenHeaderStyle}">
<GridViewColumn Header="ID LEVEL FIELD" CellTemplate="{StaticResource FatherTemplate}" Width="300"/>
<GridViewColumn Header="Value" CellTemplateSelector="{StaticResource templateSelector}" Width="80" />
<GridViewColumn Header="ID LEVEL FIELD" CellTemplate="{StaticResource DetailIdenTemplate}" Width="300"/>
</GridView>
</ListView.View>
</ListView>
This is the command in my ViewModel:
RelayCommand _unCheckCommand;
public ICommand UnCheckCommand
{
get
{
if (_unCheckCommand == null)
{
_unCheckCommand = new RelayCommand(
param => this.UnCheck(param),
param => this.CanUnCheck
);
}
return _unCheckCommand;
}
}
My goal is to pass to the Command, as parameter, the element I select in my listview. How do I do that?
I did on my own:
<DataTemplate x:Key="CheckBoxDataTemplate">
<CheckBox IsChecked="{Binding
Path=IsSelected, Mode=TwoWay}"
HorizontalAlignment="Center"
VerticalAlignment="Center" Name="aDM_LEVEL_FIELDListView" Path="SelectedItem" >
<i:Interaction.Triggers>
<i:EventTrigger EventName="Checked">
<WPFCtlr:EventToCommand Command="{Binding DataContext.UnCheckCommand, RelativeSource={RelativeSource FindAncestor,ListView,1}}" CommandParameter="{Binding ElementName=aDM_LEVEL_FIELDListView, Path=SelectedItem}" />
<!--<i:InvokeCommandAction Command="{Binding Path=SelectItemRelayCommand}" />-->
</i:EventTrigger>
</i:Interaction.Triggers>
</CheckBox>
<!--Command="{Binding Path=DataContext.UnCheckCommand}"
CommandParameter="{Binding Path=IsChecked, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type UserControl}}}" />-->
</DataTemplate>

I have ListBox with ContextMenu, I have configured MenuItem to works only if I click in selected item.
This is XAML code:
<ListBox x:Name="MessagesLb" Grid.Column="1" Margin="241,100,22.4,50" Grid.Row="1" BorderThickness="0" FontSize="14" FontWeight="SemiBold" ItemsSource="{Binding Items}" SelectionMode="Extended">
<ListBox.ItemContainerStyle>
<Style TargetType="ListBoxItem">
<Setter Property="ContextMenu">
<Setter.Value>
<ContextMenu>
<MenuItem Header="Copia" Click="MessagesLbCopySubMi_Click" />
<Separator/>
<MenuItem Header="Dettagli" />
</ContextMenu>
</Setter.Value>
</Setter>
<Style.Triggers>
<DataTrigger Binding="{Binding SelectedItems.Count, RelativeSource={RelativeSource AncestorType={x:Type ListBox}}}" Value="0">
<Setter Property="ContextMenu" Value="{x:Null}" />
</DataTrigger>
</Style.Triggers>
</Style>
</ListBox.ItemContainerStyle>
<ListBox.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding}" HorizontalAlignment="Center" VerticalAlignment="Center" />
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
I tried to add Click event in my MenuItem but it doesn't work.
Example:
<MenuItem Header="Copia" Click="MessagesLbCopySubMi_Click" />
private void MessagesLbCopySubMi_Click(object sender, RoutedEventArgs e)
{
MessageBox.Show("Click event done");
}
How can I solve this?
Define the ContextMenu as a resource:
<ListBox x:Name="MessagesLb" Grid.Column="1" Margin="241,100,22.4,50" Grid.Row="1" BorderThickness="0" FontSize="14" FontWeight="SemiBold"
ItemsSource="{Binding Items}" SelectionMode="Extended">
<ListBox.Resources>
<ContextMenu x:Key="cm">
<MenuItem Header="Copia" Click="MessagesLbCopySubMi_Click" />
<Separator/>
<MenuItem Header="Dettagli" />
</ContextMenu>
</ListBox.Resources>
<ListBox.ItemContainerStyle>
<Style TargetType="ListBoxItem">
<Setter Property="ContextMenu" Value="{StaticResource cm}" />
<Style.Triggers>
<DataTrigger Binding="{Binding SelectedItems.Count, RelativeSource={RelativeSource AncestorType={x:Type ListBox}}}" Value="0">
<Setter Property="ContextMenu" Value="{x:Null}" />
</DataTrigger>
</Style.Triggers>
</Style>
</ListBox.ItemContainerStyle>
<ListBox.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding}" HorizontalAlignment="Center" VerticalAlignment="Center" />
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
I have a DataGird, then it's include Expander and ContextMenu.
This DataGird is grouping. And, it's has different ContextMenu between Expander and DataGridItem.
However, I want to binding MenuItem Command to my command, and pass DataGird's SelectedItems or SelectedIndex to Command.
But this command is not invoked. Even if it work, the parameter is not pass when I survey some method got goal (like set property tag).
So, I want to know what's correct method.

BTW, how to cast SelectedItems when got parameter?
It's not work
private void Excute(object parameter)
{
IList list = parameter as IList;
foreach (var item in list)
{
Remove((Data)item);
}
}
So, maybe I have three problems.
The ContextMenu not working.
The CommandParameter not passing.
How to convert SelectedItems to a list?
Thanks!
A MenuItem in a ContextMenu can't use an ElementName to bind to the DataGrid because the ContextMenu and the DataGrid belong to different element trees.
What you could do is to bind the Tag property of the ItemsPresenter to the DataGrid and then bind to properties of the DataGrid through the PlacementTarget of the ContextMenu:
<ItemsPresenter Tag="{Binding RelativeSource={RelativeSource AncestorType=DataGrid}}">
<ItemsPresenter.ContextMenu>
<ContextMenu>
<MenuItem Header="Insert2" InputGestureText="Ctrl+I"
DataContext="{Binding PlacementTarget.Tag, RelativeSource={RelativeSource AncestorType=ContextMenu}}"
Command="{Binding DataContext.InsertSelectedItems}"
CommandParameter="{Binding SelectedIndex}"/>
<MenuItem Header="Remove2" InputGestureText="Ctrl+D"
DataContext="{Binding PlacementTarget.Tag, RelativeSource={RelativeSource AncestorType=ContextMenu}}"
Command="{Binding DataContext.RemoveSelectedItems}"
CommandParameter="{Binding SelectedItems}"/>
</ContextMenu>
</ItemsPresenter.ContextMenu>
</ItemsPresenter>
How to convert SelectedItems to a list?
Like you are doing. This should work provided that the binding to the SelectedItems property of the DataGrid works:
private void Execute(object parameter)
{
IList list = parameter as IList;
foreach (var item in list)
{
Remove((Data)item);
}
}
Edit:
Of course you cannot use ElementName when binding to the CommandArgument either. Try this:
<Style TargetType="{x:Type GroupItem}">
<Setter Property="Tag" Value="{Binding Path=., RelativeSource={RelativeSource AncestorType=DataGrid}}" />
<Setter Property="ContextMenu">
<Setter.Value>
<ContextMenu>
<MenuItem Header="Insert" InputGestureText="Ctrl+I"
Command="{Binding PlacementTarget.Tag.DataContext.InsertSelectedItems, RelativeSource={RelativeSource AncestorType=ContextMenu}}"
CommandParameter="{Binding PlacementTarget.Tag.SelectedIndex, RelativeSource={RelativeSource AncestorType=ContextMenu}}"/>
<MenuItem Header="Remove" InputGestureText="Ctrl+D"
Command="{Binding PlacementTarget.Tag.DataContext.RemoveSelectedItems, RelativeSource={RelativeSource AncestorType=ContextMenu}}"
CommandParameter="{Binding PlacementTarget.Tag.SelectedItems, RelativeSource={RelativeSource AncestorType=ContextMenu}}"/>
</ContextMenu>
</Setter.Value>
</Setter>
I got this in my view, I need to be able to edit the name of the Skeleton items in the TreeView via right-click -> context menu -> rename. There is a slight problem:
When I use TextBlock it works fine (TextBlock is not editable) but the binding shuts down when I use TextBox. I tried several bindings and ancestor types, to no avail. Not sure if I should switch to TextBox at all.

I have a treeview in my WPF MVVM application. Also I have a textbox that displays the value of the treenode. Right now when I expand the treeview and select a node its value is fetched and displayed on the textbox.
Now I included a checkbox that displays the numbers that appear on the textbox as words.(For eg : 11 as one one). Once I click on the checkbox the treeview loses its focus. Both the expansion of treeview and selection is lost. Only when I click the node again the value is shown in the textbox as words. How can I fix that?

How can i bind a command parameter to self?
I try like this:
<ListBox.ItemContainerStyle>
<Style TargetType="ListBoxItem">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="ListBoxItem">
<Button Content="G"
Background="Green"
Foreground="White"
Command="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type UserControl}},
Path=DataContext.LabelGoodCommand}"
CommandParameter="{Binding /}"
Width="20" Height="20" />
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</ListBox.ItemContainerStyle>
But this doesn't work.
In viewmodel listbox items binding to ObservableCollection.
CommandParameter="{Binding RelativeSource={x:Static RelativeSource.Self}}"
By this you can get the Control and in your Execute method, Use as like this,
if(pram is Button)
{
var model = ((Button)pram).DataContext;
}
you can get the Model here.
OR
<Button Content="G"
Background="Green"
Foreground="White"
Command="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type UserControl}},
Path=DataContext.LabelGoodCommand}"
CommandParameter="{TemplateBinding DataContext}"
Width="20" Height="20" />
OR
<Button Content="G"
Background="Green"
Foreground="White"
Command="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type UserControl}},
Path=DataContext.LabelGoodCommand}"
CommandParameter="{Binding DataContext,RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type UserControl}}"
Width="20" Height="20" />
If by "self", you mean the button, you can do that:
CommandParameter="{Binding RelativeSource={x:Static RelativeSource.Self}}"
If you want the current DataContext, just don't specify the path:
CommandParameter="{Binding}"
