I have a listview in which I have several listviewitems but I want to show additional information, therefore I added a expander which shows another listview within said listviewitem. But my problem is that the listview is only as wide as the listviews column width.
XAML
<ListView.View>
<GridView>
<GridViewColumn>
<GridViewColumn.CellTemplate>
<DataTemplate>
<Expander>
<ListView>
<ListView.View>
<GridView>
<GridViewColumn Header="Order number" DisplayMemberBinding="{Binding Id}"/>
<GridViewColumn Header="Name" DisplayMemberBinding="{Binding Name}"/>
<GridViewColumn Header="Price" DisplayMemberBinding="{Binding Price}"/>
</GridView>
</ListView.View>
</ListView>
</Expander>
</DataTemplate>
</GridViewColumn.CellTemplate>
</GridViewColumn>
<GridViewColumn Header="Order number" DisplayMemberBinding="{Binding OrderNumber}"/>
<GridViewColumn Header="Customer" DisplayMemberBinding="{Binding Customer}"/>
<GridViewColumn Header="Total Price" DisplayMemberBinding="{Binding CombinedPrice}"/>
<GridViewColumn Header="Urgency" DisplayMemberBinding="{Binding Urgency}"/>
</GridView>
</ListView.View>
</ListView>
Your issue is because the expander is within the cell in the listview and that cell will constrain it's size.
It will not expand to the size of it's content because ListView columns do not dynamically resize.
You could consider using a togglebutton and popup instead. Bind the isopen of the popup to the togglebutton ischecked.
A popup is a separate window effectively and hence not inside that "box" around the cell.
You could alternatively consider a datagrid which has rowdetails expand out below a row.

Ì want to write a software where there is a grid layout inside a scrollview.
I already hardcoded it, but I think I need to find a solution to make this dynamic! How can I manage to do this! I am pretty new to C# and WPF. I post a screenshot and my code so you can see what I am trying to achieve.
DataGrid is probably the best thing to use here, although you can also do it with a ListView using a GridView as the view:
<ListView ItemsSource="{Binding Items}">
<ListView.View>
<GridView>
<GridViewColumn Header="Name" DisplayMemberBinding="{Binding Name}" />
<GridViewColumn Header="Age" DisplayMemberBinding="{Binding Age}" />
<GridViewColumn Header="Gender" DisplayMemberBinding="{Binding Gender}" />
</GridView>
</ListView.View>
</ListView>
I have one ListView like this:
<ListView x:Name="TestLogListView" ItemsSource="{Binding TestLogList}">
<ListView.View>
<GridView>
<GridViewColumn Width="auto" Header="Type" DisplayMemberBinding="{Binding Path=ActionType}"/>
<GridViewColumn Width="auto" Header="Step No." DisplayMemberBinding="{Binding Path=StepNumber}"/>
<GridViewColumn Width="auto" Header="Element" DisplayMemberBinding="{Binding Path=Element}"/>
<GridViewColumn Width="auto" Header="Description" DisplayMemberBinding="{Binding Path=Description}"/>
</GridView>
</ListView.View>
</ListView>
And ScrollViewer like this:
<ScrollViewer x:Name="LogMapScrollViewer" ScrollChanged="ScrollViewer_ScrollChanged">
<StackPanel Orientation="Vertical" x:Name="LogMapStackPanel" Width="0"></StackPanel>
</ScrollViewer>
I am trying to link scrollbars of both of the controls so that if Scrollviewer is scrolled then ListView also scrolled and the other-way-round.
I dont want to place ListView inside a new ScrollViwer because the Gridview header row becomes scrollable.
Is there any way to do that?
I want to create a ListView with the names and the codes of the products in my ModelView but when I do:
<ListView ItemsSource="{Binding Path=Products}"
SelectedValue="{Binding Path=Product}" />
Only the Product Guids are showed.
How could I create a column with the Product.Name property and another onew with the Product.Code property?
Use a GridView. Perhaps like this:
<ListView ItemsSource="{Binding Products}">
<ListView.View>
<GridView>
<GridViewColumn Header="Name" DisplayMemberBinding="{Binding Name}"/>
<GridViewColumn Header="Code" DisplayMemberBinding="{Binding Code}"/>
</GridView>
</ListView.View>
</ListView>
I have the Xaml code that show everything correctly but I want to make it so the first column's content is bold:
<c:TreeView Name="JobList" SelectedItemChanged="JobList_SelectedItemChanged">
<c:TreeView.Columns>
<GridViewColumn Header="Jobs" Width="350" DisplayMemberBinding="{Binding Name}"/>
<GridViewColumn Header="Goal" Width="100" DisplayMemberBinding="{Binding Goal}"/>
<GridViewColumn Header="Messages" Width="120" DisplayMemberBinding="{Binding MessageType}"/>
</c:TreeView.Columns>
</c:TreeView>
Also can I also do this based on whether the item in the first column has sub treeview nodes or not?
I havent used the TreeListView, but usually you can put other UIElements in the header. Give this a try:
<GridViewColumn Header="Jobs" Width="350" DisplayMemberBinding="{Binding Name}">
<GridViewColumn.Header>
<TextBlock FontWeight="Bold" Text="{Binding Goal}"></TextBlock>
</GridViewColumn.Header>
</GridViewColumn>
How can I make a ListView imitate the ListView in Windows Explorer on the right side. Like how can I get icons in the ListView and get the arrows?
You can find the icons by using Google Image search. To create the ListView, you could do something like this is XAML:
<Grid>
<ListView ItemsSource="{Binding ListViewSource}">
<ListView.View>
<GridView>
<GridViewColumn Width="25">
<GridViewColumn.CellTemplate>
<DataTemplate>
<Image Source="{Binding Icon}"/>
</DataTemplate>
</GridViewColumn.CellTemplate>
</GridViewColumn>
<GridViewColumn Header="Name" DisplayMemberBinding="{Binding FileName}" Width="250"/>
<GridViewColumn Header="Date Modified" DisplayMemberBinding="{Binding DateModified}" Width="100"/>
<GridViewColumn Header="Type" DisplayMemberBinding="{Binding FileType}" Width="100"/>
<GridViewColumn Header="Size" DisplayMemberBinding="{Binding FileSize}" Width="100"/>
</GridView>
</ListView.View>
</ListView>
</Grid>
The next step is to create an ObservableCollection to hold all of the items in your list and call it ListViewSource. You can populate this collection with actual FileDirectory information, or your own kind of list. You'll then want to create your logic as to what happens when you doubleclick on an item. Since your question didn't specify to what detail you want the ListView to work, I'm going to stop there. Let us know if you want it to behave just like Windows Explorer, and we'll try to help you out.
