I would like to display a list of usercontrols binded to a listbox
next to each usercontrol there should be a button
<ListBox ItemsSource="{Binding usercontrollist}">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<!--usercontrol of the current binded items-->
<Button Content="x" HorizontalAlignment="Right"></Button>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
How can i do this in xaml code
Assuming usercontrollist is a collection of UserControl, then you should be able to do this:
<ContentControl Content="{Binding}" />

I have a XAML view that should hold instances of other views and those views should be displayed in a list, each contained in its own Expander. I'm using Caliburn.Micro and MEF to set all the components up.
The ItemsControl itself works just fine (shows the content of the view correctly):
<ItemsControl ItemsSource="{Binding CursorTools}">
<ItemsControl.ItemTemplate>
<DataTemplate>
<ContentControl cal:View.Model="{Binding}" />
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
But when I set the ItemsControl's DataTemplate to be an Expander, the Caliburn no longer "finds" the view for the viewmodel (so the expander is empty):
<ItemsControl ItemsSource="{Binding CursorTools}">
<ItemsControl.ItemTemplate>
<DataTemplate>
<!--<ContentControl cal:View.Model="{Binding}" />-->
<Expander Header="{Binding Path=Title}">
<Expander.ContentTemplate>
<DataTemplate>
<ContentControl cal:View.Model="{Binding}" />
</DataTemplate>
</Expander.ContentTemplate>
</Expander>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
The problem is that I will have many items and their content will be large enough to fill the screen, so how can I get the Expander to set its content properly?
Expander is actually a ContentControl so this should work:
<Expander Header="{Binding Path=Title}" cal:View.Model="{Binding}" />
I have to make listbox with textbox in it... and it has to be dynamic. I have observable collection in code behind and I want to bind that for listbox. I want dynamic listbox and this list should have editable textbox in it. So, basically I want to bind multiplr textbox from listbox. Any help would be appreciated
<ListBox HorizontalAlignment="Left" Name="ListTwo" Height="100" Margin="286.769,165.499,0,0" VerticalAlignment="Top" Width="100" ItemsSource="{Binding Source=obs}">
<ListBox.ItemTemplate>
<DataTemplate>
<TextBox Name="TextBoxList"></TextBox>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
By doing this, I have number of textbox same as items in observable collection but textbox's text is not set up.
If the items in your ObservableCollection are just plain strings, then you can data bind to the whole string value like this:
<ListBox Name="ListTwo" ItemsSource="{Binding Source=obs}" ... >
<ListBox.ItemTemplate>
<DataTemplate>
<TextBox Name="TextBoxList" Text="{Binding}" />
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
From the Binding.Path Property page on MSDN:
Optionally, a period (.) path can be used to bind to the current source. For example, Text="{Binding}" is equivalent to Text="{Binding Path=.}".
Note that if you had some objects with properties in the collection, then #nit's answer would have been correct as you would need to reference the relevant property name:
<ListBox Name="ListTwo" ItemsSource="{Binding Source=obs}" ... >
<ListBox.ItemTemplate>
<DataTemplate>
<TextBox Name="TextBoxList" Text="{Binding PropertyName}" />
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
You will have to Bind your textbox to the property in your class of which observable collection you have bound
<ListBox HorizontalAlignment="Left" Name="ListTwo" Height="100" Margin="286.769,165.499,0,0" VerticalAlignment="Top" Width="100" ItemsSource="{Binding Source=obs}">
<ListBox.ItemTemplate>
<DataTemplate>
<TextBox Binding="{Binding PROPERTYINCLASS}"></TextBox>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
What in the world is wrong with this ListBox? It is showing items as plain strings, not using the template I have provided:
<ListBox>
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<Ellipse Width="20" Height="20" Fill="LightBlue" />
<TextBlock Text="{TemplateBinding Content}" Foreground="Red" />
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
<ListBox.Items>
<ListBoxItem>html</ListBoxItem>
<ListBoxItem>head</ListBoxItem>
<ListBoxItem>body</ListBoxItem>
<ListBoxItem>table</ListBoxItem>
<ListBoxItem>tr</ListBoxItem>
<ListBoxItem>td</ListBoxItem>
</ListBox.Items>
</ListBox>
From the Remarks section in the ItemTemplate MSDN page:
When you set an ItemTemplate on an ItemsControl, the UI is generated
as follows (using the ListBox as an example):
1.During content generation, the ItemsPanel initiates a request for the ItemContainerGenerator to create a container for each data item.
For ListBox, the container is a ListBoxItem. The generator calls back
into the ItemsControl to prepare the container.
2.Part of the preparation involves the copying of the ItemTemplate of the ListBox to be the ContentTemplate of the ListBoxItem.
3.Similar to all ContentControl types, the ControlTemplate of a ListBoxItem contains a ContentPresenter. When the template is applied,
it creates a ContentPresenter whose ContentTemplate is bound to the
ContentTemplate of the ListBoxItem.
4.Finally, the ContentPresenter applies that ContentTemplate to itself, and that creates the UI.
These steps are apparently not executed when you create ListBoxItem instances directly in XAML. It is however not strictly necessary to bind the ItemSource property. You may also directly set items like this:
<ListBox xmlns:sys="clr-namespace:System;assembly=mscorlib">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<Ellipse Width="20" Height="20" Fill="LightBlue" />
<TextBlock Text="{TemplateBinding Content}" Foreground="Red" />
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
<ListBox.Items>
<sys:String>html</sys:String>
<sys:String>head</sys:String>
<sys:String>body</sys:String>
<sys:String>table</sys:String>
<sys:String>tr</sys:String>
<sys:String>td</sys:String>
</ListBox.Items>
</ListBox>
public class MyViewModel
{
public List<String> Items
{
get { return new List<String> { "html", "head", "body","table","tr","td" }; }
}
}
//This can be done in the Loaded event of the page:
DataContext = new MyViewModel();
Your XAML
<ListBox Margin="20" ItemsSource="{Binding Items}">
<ListBox.ItemTemplate>
<DataTemplate>
<Ellipse Width="20" Height="20" Fill="LightBlue" />
<StackPanel Orientation="Horizontal">
<TextBlock Text="{Binding}" />
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
I am currently working on a project using MVVM pattern and can't find anywhere a solution how to bind an ObservableCollection to a TabControl which has a template for an item of it.
For example, this is where I got so far:
<TabControl ItemsSource="{Binding ConnStringBufferOC}">
<TabControl.ItemTemplate>
<DataTemplate>
<Grid>
<TextBox Text="{Binding Username}"/>
<!-- Controls here -->
</Grid>
</DataTemplate>
</TabContro.ItemTemplate>
</TabControl>
This however only partialy works. It creates controls in the tab header area instead of the tab content area. I would want to bind each item to a new tab which has a header of a bound source from OC, for example:
Header="{Binding Name}"
And in the content area of each tab I would like to have controls, which have contents bound from the ObservableCollection in this example ConnStringBufferOC. So every tab has same controls only content bound to the controls is different.
You need to specify ContentTemplate for tab content and ItemTemplate for tab header
<TabControl ItemsSource="{Binding ConnStringBufferOC}">
<TabControl.ContentTemplate>
<DataTemplate>
<Grid>
<TextBox Text="{Binding Username}"/>
<!-- Controls here -->
</Grid>
</DataTemplate>
</TabControl.ContentTemplate>
<TabControl.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding Name}"/>
</DataTemplate>
</TabControl.ItemTemplate>
</TabControl>
I define my ItemsControl that contain RadioButtons.
I want to access the Items contained in ItemsControl that are attached as binding child - and when I try to access the ItemsControl.Items I can't see the RadioButtons.
The code:
<ItemsControl Name="itemsControl" >
<ItemsControl.ItemTemplate>
<DataTemplate>
<RadioButton Content="{Binding Key}" />
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
This is because you are setting the ItemTemplate of the control, ant not its items. To add items do it like this:
<ItemsControl Name="itemsControl" >
<ItemsControl.Items>
<RadioButton Content="{Binding Key}" />
</ItemsControl.Items>
</ItemsControl>
