I'm wondering how to prevent the columns from resizing from the user.
My UI component is a GridView nested inside a ListView.
I couldn't find any properties to prevent this functionality.
<ListView>
<ListView.View>
<GridView AllowsColumnReorder="False">
<GridViewColumn Width="20">
<CheckBox />
</GridViewColumn>
<GridViewColumn Header="Measures" Width="180"/>
</GridView
</ListView.View>
</ListView>
I would just like to stop users from being able to resize columns

I want to create a style for my ListViews in my WPF app, which makes them appear more like the Windows Explorer ListView. The thing I am stuck on is the ellipsis (...) that appears in the Grid/Details view when a column is too narrow to fix the text.
I know I can override the cell template of each column, and explicitly set the TextTrimming mode to get ellipsis on a per-column basis. However, I want a style that I can apply to any ListView to get the same behavior.
I want to be able to define the listview like this:
<ListView ItemsSource="{Binding Library}" Style="{StaticResource ExplorerListStyle}">
<ListView.View>
<GridView>
<GridViewColumn Width="90" Header="Title" DisplayMemberBinding="{Binding Title}" />
<GridViewColumn Width="60" Header="Author" DisplayMemberBinding="{Binding Author}" />
</GridView>
</ListView.View>
</ListView>
I also want to be able to override the cell template for some columns, e.g. to set the text color, ideally while still inheriting the TextTrimming mode for the text in the template.
The only way I have managed to achieve this so far is to explicitly override the TextBlock style inside the ListView:
<ListView ItemsSource="{Binding Library}">
<ListView.Resources>
<Style TargetType="TextBlock">
<Setter Property="TextTrimming" Value="CharacterEllipsis" />
</Style>
</ListView.Resources>
<ListView.View>
<GridView>
<GridViewColumn Width="90" Header="Title" DisplayMemberBinding="{Binding Title}" />
<GridViewColumn Width="60" Header="Author" DisplayMemberBinding="{Binding Author}" />
</GridView>
</ListView.View>
</ListView>
However, this seems a bit heavy handed, and it's not possible, as far as I can tell, to set this in a style.
So, I'm looking for another way to set the TextTrimming mode for a GridViewColumns header and cells, that can be set in a style, and doesn't require explicit CellTemplates.
Thanks,

I am implementing an application in wpf , MVVM pattern.
I want to implement a listview with objects. These objects contains a list. On default this list contains only 1 object. But in the listview, I want to show that certain object. So the properties of the object in the list. This is my first problem.
But I also have to be able to have more objects in this list. My second problem is that i don't really know how to realise this? And i also have to show the properties of these objects in the listview.
Maybe a treeview? but i don't get how that i got to begin on this..
Someone with some ideas?
You can arbitrarily nest DataTemplates, e.g.
<ListView ItemsSource="{Binding Data}">
<ListView.View>
<GridView>
<GridViewColumn Header="Name" DisplayMemberBinding="{Binding Name}"/>
<!-- Internal Manchines list gets its own ListView -->
<GridViewColumn Header="Machines">
<GridViewColumn.CellTemplate>
<DataTemplate>
<ListView ItemsSource="{Binding Machines}">
<ListView.View>
<GridView>
<GridViewColumn Header="Model" DisplayMemberBinding="{Binding Model}"/>
<GridViewColumn Header="Manufacturer" DisplayMemberBinding="{Binding Manufacturer}"/>
</GridView>
</ListView.View>
</ListView>
</DataTemplate>
</GridViewColumn.CellTemplate>
</GridViewColumn>
<GridViewColumn Header="Occupation" DisplayMemberBinding="{Binding Occupation}"/>
<GridViewColumn Header="Status" DisplayMemberBinding="{Binding Status}"/>
</GridView>
</ListView.View>
</ListView>
This can be improved in terms of alignment, e.g. you could set up a Grid in the DataTemplate with a shared size column to make all lists the same width (making the internal columns align might be a bit hard though)
Further you could define a style to collapse empty lists (which otherwise would show the header without items).
I have a GridView control:
<GridView>
<GridViewColumn Header="Name" Width="500">
<GridViewColumn.CellTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
</StackPanel>
</DataTemplate>
</GridViewColumn.CellTemplate>
</GridViewColumn>
<GridViewColumn DisplayMemberBinding="{Binding TypeName}" Header="Type" Width="100" />
</GridView>
for the first column("name"), I would like to have a mechanism that when every record is binded, will be a way(e.g. event), so that I can dynamically add controls to the StackPanel.
for example, my data has a column called AnimalType, if it is a cat, I will add an image to the StackPanel; if it is a cow, I will put a media element to play a movie; if it is a dog, I will put a hyper link, etc.
How can I do that?
Take a look at the DataTemplateSelector class....

I am trying to implement a ListView with a GridView with sortable columns.
To sort the ListView I hook up the Click event for the GridViewColumnHeaders and adding SortDescriptors to the default view source (similar to what is done in MSDN).
Something like this:
<ListView ItemsSource="MY ITEMS SOURCE BINDING">
<ListView.View>
<GridView>
<GridView.Columns>
<GridViewColumn DisplayMemberBinding="MY DISPLAYMEMBER BINDING">
<GridViewColumnHeader Content="My Header" Click="ColumnHeaderClicked"/>
This all works fine, but I would like to generalize it a bit. To do that I simply derived GridViewColumnHeader and wrote a click-handler. I know there are many sortable list view implementations out there typically deriving from ListView, but I was just wondering if this approach is possible.
Something like this:
<ListView ItemsSource="MY ITEMS SOURCE BINDING">
<ListView.View>
<GridView>
<GridView.Columns>
<GridViewColumn DisplayMemberBinding="MY DISPLAYMEMBER BINDING">
<local:SortableGridViewColumnHeader Content="My Header"/>
For this to work I need to navigate from the SortableGridViewColumnHeader code to the containing ListView in order to set new SortDescriptors.
I tried navigating up the Parent ladder, but the GridViewColumnHeader is not a visual child of my ListView. Surely I could make a dependency property and bind it to the ListView, but there must be a way to navigate to it instead.
How would I do that in code? (I am not looking for answers on how to sort a WPF ListViews in general, I am wondering if it can be done this way).
EDIT
It turned out that what I needed was this parent searcher in the click-handler of my GridViewColumnHeader derivative.
DependencyObject parent = this;
do
{
parent = VisualTreeHelper.GetParent(parent);
if (parent == null) return;
} while (!(parent is ListView));
Now my sorting works like a charm.
There is a much easier way to do that, using an attached property. Check out this article for details.
<ListView ItemsSource="{Binding Persons}"
IsSynchronizedWithCurrentItem="True"
util:GridViewSort.AutoSort="True">
<ListView.View>
<GridView>
<GridView.Columns>
<GridViewColumn Header="Name"
DisplayMemberBinding="{Binding Name}"
util:GridViewSort.PropertyName="Name"/>
<GridViewColumn Header="First name"
DisplayMemberBinding="{Binding FirstName}"
util:GridViewSort.PropertyName="FirstName"/>
<GridViewColumn Header="Date of birth"
DisplayMemberBinding="{Binding DateOfBirth}"
util:GridViewSort.PropertyName="DateOfBirth"/>
</GridView.Columns>
</GridView>
</ListView.View>
</ListView>
I might sound dumb here, but I want to do something really simple. At design time, I want to add columns to a listview control and add some data to it. I need to add combobox in each column of the listview. The thing I am not able to find is where to mention the column number in the listviewitem. Any help appreciated guys.
<ListView IsSynchronizedWithCurrentItem="True" Margin="8,68,304,188"
BorderThickness="2,2,2,2">
<ListView.View>
<GridView>
<GridViewColumn Width="150" Header="Column1"/>
<GridViewColumn Width="150" Header="Column2"/>
</GridView>
</ListView.View>
<ListViewItem>
</ListViewItem>
</ListView>
Each column in the listviewitem is rendered based on the GridView definition, so there is no real concept of column numbers. What you do is bind objects to the the listview's itemsource and it creates listviewitems from it. Thus, there are a few hoops to jump through.
This link has an example of how to do some simple object data binding. The advantage of this is what binding structure you have for design time can probably be reused for run-time if you set the datacontext/itemsource to an empty object instead of the static one in XAML.
If you're doing this to show examples or you just have a static data source that you want to use, I would recommend using the XmlDataProvider. Then you'd change your ListView to be like this,
<ListView IsSynchronizedWithCurrentItem="True" Margin="8,68,304,188"
BorderThickness="2,2,2,2">
<ListView.View>
<GridView>
<GridViewColumn Width="150" Header="Column1" DisplayMemberPath="{Binding XPath=/A/B}"/>
<GridViewColumn Width="150" Header="Column2" DisplayMemberPath="{Binding XPath=/A/C"/>
</GridView>
</ListView.View>
<ListViewItem>
</ListViewItem>
</ListView>
