I have a UserControl which I need to keep adding to a StackPanel during runtime (per User's action). I want a close button (a small 'x') on the right side top corner for each item in StackPanel.
I could do this: add my UserControl to some Panel which has the 'x' button that glows on mouse hover, which when clicked deletes the item from the StackPanel.
However, I am looking for a better solution to this problem. Like is there any control out there which offers a similar functionality?
I was looking for TileView. All I need is a single row of Tiles which keep added per users input, and have the ability to delete a "Tile". Each tile would contain my UserControl.
Please let me know,
you can use tileview, but Grid can work here too, you can add you usercontrol to a cell and on other cell you can give a close button and on the close button click you can remove that row from the grid , if you are going to add more than one usercontrol than Grid can be easily maintain.
You can do this easily with the ItemsControl. Think of it like a ListBox without the selection. Just modify it a little:
<ItemsControl HorizontalAlignment="Center" VerticalAlignment="Center">
<ItemsControl.ItemTemplate>
<DataTemplate>
<Border Padding="4" Background="CornflowerBlue">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition/>
</Grid.RowDefinitions>
<Button Content="Close" HorizontalAlignment="Right"/>
<Grid Margin="4" Grid.Row="1">
<!-- put your usercontrol here -->
</Grid>
</Grid>
</Border>
</DataTemplate>
</ItemsControl.ItemTemplate>
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel Orientation="Horizontal"/>
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
</ItemsControl>

I have a very beautiful Grid control with a WebView in it and I am trying for more than 2 hours to wrap it in a ListViewItem.
This is my grid:
<Grid Width="450" Margin="0,-270,0,-200" VerticalAlignment="Stretch" HorizontalAlignment="Stretch">
<WebView x:Name="Browser" Source="http://someurl.com" Margin="0,0,0,-150/>
</Grid>
and I am very happy with it's design.
When I try to wrap it in a ListViewItem the margins change a lot and I cant seem to find the correct one to make it look exactly the way the old Grid used to.
This is my ListView:
ListView x:Name="MyList1" BorderThickness="0" Width="500">
<ListView.ItemTemplate>
<DataTemplate>
<Grid Width="450" Margin="0,-270,0,-200" VerticalAlignment="Stretch" HorizontalAlignment="Stretch">
<WebView x:Name="Browser" Source="http://someurl.com" Margin="0,0,0,-150/>
</Grid>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
The margins are hiding some part of the WebView. Hence the reason I need exactly the same margin.
I am trying to wrap it to a ListView to be able to create multiple Items.
I have a structure in WPF as follows:
<Grid x:Name="Grid" Background="#FFE5E5E5">
<ScrollViewer VerticalScrollBarVisibility="Auto" HorizontalScrollBarVisibility="Disabled" Height="790" Margin="13,9,10,0" CanContentScroll="True" HorizontalContentAlignment="Center" VerticalContentAlignment="Stretch">
<StackPanel x:Name="StackPanel" Height="770" Width="650" HorizontalAlignment="Center"/>
</ScrollViewer>
</Grid>
My program puts several UserControls inside the StackPanel. When I select one of the elements of the UserControl that is not on the top of the ScrollViewer, it automatically moves to the top.
Is there a way to prevent this and leave it in place and only allow the user to scroll up and down whenever he/she wants to?
I do not know what the container/control im looking for would be called, so I cannot really search for it.
Add More of Same Usercontrol Usercontrol
Clicking on + would add a new instance of My Usercontrol to the right of the existing ones
Clicking on X would dispose the usercontrol that was clicked
I'm not really looking for a tab control that would put each new instance on a new tab, but if there is nothing else then it might do.
The design is not to be as shown in the image obviously, the image just illustrates the basic idea
Any keyword/name suggestions or links to existing implementations?
e.g. Maybe there is a style that turns a ListBox into something suitable?
I would use an ItemsControl and customize it's ItemsPanelTemplate to be whatever you want.
ItemsControls are meant for iterating through a collection of objects, and displaying them in whatever form you want. I wrote some simple code samples of them here if you're interested, or here's another quick example:
<DockPanel x:Name="RootPanel">
<Button Style="{StaticResource AddButtonStyle}"
DockPanel.Dock="Right" VerticalAlignment="Center"
Command="{Binding AddItemCommand" />
<ScrollViewer>
<ItemsControl ItemsSource="{Binding MyCollection}">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel Orientation="Horizontal" />
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemTemplate>
<DataTemplate>
<Grid>
<local:MyUserControl />
<Button Style="{StaticResource RemoveButtonStyle}"
Command="{Binding ElementName=RootPanel, Path=DataContext.RemoveItemCommand}"
CommandParameter="{Binding }"
HorizontalAlignment="Left" VerticalAlignment="Top" />
</Grid>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</ScrollViewer>
</DockPanel>
Your ItemsControl would be bound to an ObservableCollection of objects, and your Add/Remove buttons would simply add/remove items from that collection. Since it is an ObservableCollection, it will notify the UI when the collection gets changed and automatically update.
You can indeed use a ListBox and set its ItemTemplate and ItemsPanelTemplate:
<ListBox>
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel Orientation="Horizontal"></StackPanel>
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
<ListBox.ItemTemplate>
<DataTemplate>
<Label Content="{Binding Name}" />
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
Of course, your ItemTemplate would be a reference to your control.
You could look at something called a carousel control which uses a list of objects behind it and displays them similarly to itunes. This could be a bit over the top but is one solution. An example can be seen here
If this is too advanced for your needs, could it be as simple as a stackpanel with a scrollbar which is bound to a list of your user controls?
I have a recursively defined user control that needs the following properties:
there are two columns
the first contains a single border around some text
the second column contains a stack of these same type of controls (the recursive part)
if the box in the first column is shorter than the total height of the stacked boxes in the second column, the box should expand to make both columns the same height.
If the total height of the second column is shorter than the box in the first column, then the last item in the second column's stack should expand so they are the same height.
so for example, it might look like this:
Ok, so far what I have done is create a horizontal stack panel where the first item is a dock-panel containing a border and text... the second column is a vertical stack panel bound to a sublist, creating the recursive user control... like this..
<StackPanel Orientation="Horizontal" Background="AliceBlue">
<local:TMRequirementView Requirement="{Binding Baseline}" />
<StackPanel Orientation="Vertical">
<ItemsControl ItemsSource="{Binding Requirements}">
<ItemsControl.ItemTemplate>
<DataTemplate>
<local:TMGridView Baseline="{Binding}" />
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</StackPanel>
Where the requirement looks like this:
<DockPanel>
<Border MinHeight="50"
BorderBrush="Black" BorderThickness="2">
<TextBlock Text="{Binding Description}"
TextWrapping="Wrap" Background="Transparent" Height="Auto" />
</Border>
</DockPanel>
Now this works great if the stacked column is taller, but it doesn't work if the first column is taller, and I get gaps. Any idea how to handle this mutual height dependency?
Update:
So by adding a border around the right columns stack panel, I was able to see that the stackpanel actually did receive the min-height changes. However, even though there was room to expand, the children of the stack panel didn't automatically update. If I fix the minheight of the stack panel before hand to something large, the children fill up. What I need to figure out is how to update the chidren's height based on changes to the stack panel's min-height.
I think the Grid in this layout does what you describe. I put it in a DockPanel so that you can see how it resizes. Try typing stuff into the text boxes and watch how it behaves:
<Page
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<DockPanel>
<Grid DockPanel.Dock="Top">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<TextBox AcceptsReturn="True" Grid.Row="0" Grid.Column="0" Grid.RowSpan="3"></TextBox>
<TextBox AcceptsReturn="True" Grid.Row="0" Grid.Column="1"></TextBox>
<TextBox AcceptsReturn="True" Grid.Row="1" Grid.Column="1"></TextBox>
<TextBox AcceptsReturn="True" Grid.Row="2" Grid.Column="1"></TextBox>
</Grid>
<TextBlock/>
</DockPanel>
</Page>
All three rows of the Grid will have the height of a TextBox at a minimum (when you replace the TextBoxes with other elements, you'll need to set minimum heights to keep them from vanishing if they're empty). Since the third row is star-sized, it will size itself to all remaining vertical space left after the first two rows are arranged. So if there's a bunch of content in the first column, the third row in the second column gets taller.
Edit
Actually, there's no reason to even screw around with a Grid in this case: What you're describing is really the behavior of the DockPanel:
<DockPanel>
<DockPanel DockPanel.Dock="Top">
<DockPanel.Resources>
<Style TargetType="Label">
<Setter Property="DockPanel.Dock" Value="Top"/>
<Setter Property="Background" Value="Lavender"/>
<Setter Property="Margin" Value="1"/>
</Style>
</DockPanel.Resources>
<DockPanel LastChildFill="True">
<Label>Foo</Label>
</DockPanel>
<DockPanel LastChildFill="True">
<Label>Foo</Label>
<Label>Bar</Label>
<Label>Baz</Label>
<Label>Bat</Label>
</DockPanel>
</DockPanel>
<Label/>
</DockPanel>
In WPF, Is there a simple way to stop TabItems in a TabControl from being repositioned when the selected TabItem changes? So that clicking on a TabItem would simply display its contents, but not reposition the TabItems as it usually does (by moving the selected TabItem to the bottom row of tabs if it wasn't there already).
Edit: To clarify, I do want the tabs to be displayed in multiple rows, I just don't want the tab headers to be repositioned when a TabItem from a row other than the bottom row is selected. I'd like the collection of headers to remain completely static, but for the contents of that TabItem to still be displayed when its header is clicked.
Thanks!
I know its late but I had to figure this out today so here goes.
Basically you need to create your own control template for the tab control and use a different panel to contain your tab items.
Here is a simplified example using a WrapPanel.
<Style TargetType="TabControl" x:Key="MyTabControl">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="TabControl">
<Grid SnapsToDevicePixels="true" KeyboardNavigation.TabNavigation="Local" HorizontalAlignment="Stretch">
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<WrapPanel x:Name="HeaderPanel" HorizontalAlignment="Center" VerticalAlignment="Top" IsItemsHost="true"
Grid.Row="0" KeyboardNavigation.TabIndex="1" />
<ContentPresenter Grid.Row="1" x:Name="PART_SelectedContentHost" ContentSource="SelectedContent" Margin="10" />
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
You then use this as follows
<TabControl Style="{StaticResource MyTabControl}" ....
You can download the control template samples here
If you have Blend you can Edit a copy of the template for your tab control to remove this behavior I believe.
