I was wondering if there is a way to show multiple elements inside listview.view.
SampleCode (which doesnst work)
<ListView
x:Name="Somename"
ItemsSource="{Binding someObservableCollection}">
<ListView.View>
<TextBlock></TextBlock>
<TextBlock></TextBlock>
<TextBlock></TextBlock>
<GridView>
<GridViewColumn Header="Column 1" >
<GridViewColumn.CellTemplate>
<DataTemplate>
<TextBlock></TextBlock>
</DataTemplate>
</GridViewColumn.CellTemplate>
</GridViewColumn>
<GridViewColumn Header="Column 2">
<GridViewColumn.CellTemplate>
<DataTemplate>
<TextBlock></TextBlock>
</DataTemplate>
</GridViewColumn.CellTemplate>
</GridViewColumn>
</GridView>
</ListView.View>
</ListView>
Sample Data properties for a person.
Name
Age
Id
OldData1
OldData2
OldData3
NewData1
NewData2
NewData3
I am trying to show Name, age, Id and 3 textblocks
and then in a grid, compare olddata vs new data.
I tried doing with itemtemplate and then doing stackpanel with grid inside, but that grid looks very basic and would prefer gridview since it looks better.

We are working on a ListView (C# WPF) and we didn't found how bind a list of items in columns, with each item containing itself a list of items with the same columns.
Let's illustre this in an example :
!
We got an observable collection on objects with parameters (name, etc.) and each object contain another observable collection of objects with the sames parameters (exept they haven't a list). So we want to list it in a ListView but we can't figure how !
We do not know enough ListView to implement this structure, some advices ?
Thanks in advance
I think the best way is :
XAML :
<Window.Resources>
<DataTemplate x:Key="gridViewSecondCellTemplate1">
<StackPanel Width="100">
<TextBlock Text="{Binding Content}" FontSize="15" />
</StackPanel>
</DataTemplate>
<DataTemplate x:Key="gridViewCellTemplate1">
<StackPanel Width="100">
<TextBlock Text="{Binding Title}" FontSize="15" />
<ListView ItemsSource="{Binding MySecondSource}>
<ListView.View>
<GridView>
<GridViewColumn Header="{Binding Subtitle}" CellTemplate="{StaticResource gridViewSecondCellTemplate1}"/>
</GridView>
</ListView.View>
</ListView>
</StackPanel>
</DataTemplate>
</Window.Resources>
<ListView ItemsSource="{Binding MySource}">
<ListView.View>
<GridView>
<GridViewColumn Header="Col 1" Width="100" CellTemplate="{StaticResource gridViewCellTemplate1}"/>
</GridView>
</ListView.View>
</ListView>
I didn't try this code. Try it, and say me if it is OK.
I have 2 ObservableCollection lists, which we can call A and B, then I have a GridView that I want to bind to list A and a ComboBox INSIDE that GridView, that I want to bind to list B.
I've set the ItemsSource property of the GridView by code: gridview.ItemsSource=A (and it works!). About the ComboBox its instance it is not available by code, I suppose because its definition it is enclosed between the DataTemplate tags; so I wonder how to bind the combo to list B, either by code or by XAML.
Follows the XAML code:
<ListView Grid.Row="0" Grid.Column="1" HorizontalAlignment="Stretch" Margin="0,0,0,0" Name="lstReplacements" VerticalAlignment="Stretch">
<ListView.View>
<GridView>
<GridViewColumn HeaderContainerStyle="{StaticResource MyHeaderStyle}" Header="Wrong text" DisplayMemberBinding="{Binding Word}"/>
<GridViewColumn HeaderContainerStyle="{StaticResource MyHeaderStyle}" Header="Replacement" Width="60" DisplayMemberBinding="{Binding Replacement}" />
<GridViewColumn HeaderContainerStyle="{StaticResource MyHeaderStyle}" Header="Type" Width="30">
<GridViewColumn.CellTemplate>
<DataTemplate>
<ComboBox ItemsSource="{??????}" DisplayMemberPath="??????" Grid.Row="1" Grid.Column="0" Name="cmbCorrectionType" Width="75" />
</DataTemplate>
</GridViewColumn.CellTemplate>
</GridViewColumn>
</GridView>
</ListView.View>
</ListView>
Thanks in advance for the support!

I assume this control is in UserControl and you have set DataContext of that UserControl to the class instance where your both collections CollectionA and CollectionB resides.
You can then bind using RelativeSource:
<ComboBox ItemsSource="{Binding DataContext.CollectionB,
RelativeSource={RelativeSource Mode=FindAncestor,
AncestorType=UserControl}}"/>
Also you can set DataContext of ListView to the class instance and all you need to do is change AncestorType to ListView in place of UserControl in above binding.
I've been messing around with checkboxes and listview in my wpf application. Selecting multiple items seems to work properly, but when I click on an item and not on its checkbox it selects the item and deselects all the others previously selected, how can I fix this ?
Here's my code:
<ListView Name="NewPlace_ActionsList" HorizontalAlignment="Left" Height="254" Margin="10,74,0,0" VerticalAlignment="Top" Width="389" >
<ListView.View>
<GridView>
<GridViewColumn>
<GridViewColumn.CellTemplate>
<DataTemplate>
<CheckBox Tag="{Binding Id}" IsChecked="{Binding RelativeSource={RelativeSource AncestorType={x:Type ListViewItem}}, Path=IsSelected}" />
</DataTemplate>
</GridViewColumn.CellTemplate>
</GridViewColumn>
<GridViewColumn Header="Codice" DisplayMemberBinding="{Binding Path=Id}" />
<GridViewColumn Header="Nome" DisplayMemberBinding="{Binding Path=Name}" />
<GridViewColumn Header="Descrizione" DisplayMemberBinding="{Binding Path=Desc}" />
</GridView>
</ListView.View>
</ListView>
What do you want to accomplish? The system behaves exactly to what you coded: the checkbox is selected only in the selected row. Because the Checkbox "follows" the IsSelected of the row (ListViewItem).
So far i have been working with listview without any problem. I have been able to pass multiple columns and fill them with images, text etc. I decided to do the same thing with a listbox but things there got complicated.
In a listview i do the following :
<DataTemplate x:Key="ImageTemplate" >
<Image x:Name="FavoriteImageList" Tag="{Binding tagger}" Width="12" Height="12" Source="{Binding ImageSource}" MouseLeftButtonDown="FavoriteImageList_MouseLeftButtonDown"/>
</DataTemplate>
<ListView x:Name="Citys">
<ListView.View>
<GridView ColumnHeaderContainerStyle="{StaticResource myHeaderStyle}">
<GridViewColumn Width="90" Header="Image" CellTemplate="{StaticResource ImageTemplate}"/>
<GridViewColumn Width="178" Header="Name" DisplayMemberBinding="{Binding Name}" />
<GridViewColumn Width="178" Header="City" DisplayMemberBinding="{Binding City}"/>
<GridViewColumn Width="140" Header="Author" DisplayMemberBinding="{Binding Author}"/>
</GridView>
</ListView.View>
</ListView>
And i fill columns like this :
foreach(var fav in Favorites)
{
Citys = new List<ACity>()
{
new ACity() {tagger = Name ,ImageSource = ImageSource ,Name= Name, Author= Author, City = City}
};
ListBox.Items.Add(Citys);
}
If I do this in a listbox, it will fill with (Collection).
Is there a way to do this in a listbox, passing images buttons strings in a listbox row?
See the example from the MSDN ItemsControl.ItemTemplate
<ListBox Width="400" Margin="10"
ItemsSource="{Binding Source={StaticResource myTodoList}}">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel>
<TextBlock Text="{Binding Path=TaskName}" />
<TextBlock Text="{Binding Path=Description}"/>
<TextBlock Text="{Binding Path=Priority}"/>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
It should be pretty straight forward to match with your example.
I am trying to bind a Dictionary property stored in a EffectViewModel inside an ObservableCollection, but it appears as "(Collection)" in the column I want to see as checkboxes.
Xaml for the GridViewColumn is this:
<GridViewColumn
Width="100"
Header="GPU"
DisplayMemberBinding="{Binding ShaderSupport}">
<GridViewColumn.CellTemplate>
<DataTemplate>
<CheckBox Margin="0"
HorizontalAlignment="Center"
IsChecked="{Binding Value}"/>
</DataTemplate>
</GridViewColumn.CellTemplate>
</GridViewColumn>
ShaderSupport is of type Dictionary<ShaderType, bool> where I just want to read in the bool value for ShaderType.GPU for this GridViewColumn.
Any ideas?
EDIT: Using this shows me the bool value as string, so I am in the right path I think:
DisplayMemberBinding="{Binding ShaderSupport[GPU]}">
Try this:
<GridViewColumn
Width="100"
Header="GPU">
<GridViewColumn.CellTemplate>
<DataTemplate>
<CheckBox Margin="0"
HorizontalAlignment="Center"
IsChecked="{Binding ShaderSupport[CPU]}"/>
</DataTemplate>
</GridViewColumn.CellTemplate>
</GridViewColumn>
