Just wondering if it's possible to bind the listbox in the XAML below to the GridViewDataColumn in a relative manner - I can do it explicitly but I want to add the Columns dynamically and would like to set up some logic in the the Column's Converter.
<navigation:Page.Resources>
<converters:DebugConverter x:Key="DebugConverter"/>
<converters:DebugInnerConverter x:Key="DebugInnerConverter"/>
<DataTemplate x:Key="ChemistryResultsTemplate">
<ListBox><!-- Bind this to parent GridViewDataColumn data -->
<ListBox.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding ProfileResult}"></TextBlock>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</DataTemplate>
</navigation:Page.Resources>
<Grid x:Name="LayoutRoot">
<telerik:RadGridView x:Name="LabReportGrid" AutoGenerateColumns="True">
<telerik:RadGridView.Columns>
<telerik:GridViewDataColumn DataMemberBinding="{Binding ChemistryResults, Converter={StaticResource DebugConverter}}"
CellTemplate="{StaticResource ChemistryResultsTemplate}"
x:Name="Testing">
</telerik:GridViewDataColumn>
</telerik:RadGridView.Columns>
</telerik:RadGridView>
</Grid>

When an item is selected in my ListView, I want to display a specific user control in the my ContentControl.
Using the following code, my content control merely displays "Microsoft.UI.Xaml.Data.CollectionView". I understand the ContentControl is trying to bind to the entire list, but how do I tell it to bind to the CollectionViewSource's CurrentItem?
<Page.Resources>
<CollectionViewSource x:Name="PChoicesCollectionView" Source="{x:Bind ViewModel.PChoices}"/>
</Page.Resources>
<ListView ItemsSource="{Binding Source={StaticResource PChoicesCollectionView}}">
<ListView.ItemTemplate>
<DataTemplate x:DataType="p:PBase">
<Grid>
<TextBlock Text="{x:Bind Name.Name}" FontSize="18" FontWeight="SemiBold"/>
</Grid>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
<ContentControl ContentTemplateSelector="{StaticResource pDataTemplateSelector}" Content="{Binding Source={StaticResource PChoicesCollectionView}}"/>
You could bind to the SelectedItem property of the ListView:
<ListView Name="lv"
ItemsSource="{Binding Source={StaticResource PChoicesCollectionView}}">
<ListView.ItemTemplate>
<DataTemplate x:DataType="p:PBase">
<Grid>
<TextBlock Text="{Binding}" FontSize="18" FontWeight="SemiBold"/>
</Grid>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
<ContentControl ContentTemplateSelector="{StaticResource pDataTemplateSelector}"
Content="{Binding SelectedItem, ElementName=lv}"/>
I need to find the LongListMultiSelector inside ListBox .
<ListBox x:Name="ListBoxName" Width="400">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel>
<Bewise:ExpanderControl x:Name="bewiseControl" HeaderText="{Binding Title, Mode=OneWay}" Width="400" >
<Bewise:ExpanderControl.ContentArea>
<toolkit:LongListMultiSelector ItemsSource="{Binding LstProdcuts}" x:Name="LongList">
<toolkit:LongListMultiSelector.ItemTemplate >
<DataTemplate>
<StackPanel >
<TextBlock Text="{Binding Title}" />
</StackPanel>
</DataTemplate>
</toolkit:LongListMultiSelector.ItemTemplate>
</toolkit:LongListMultiSelector>
</Bewise:ExpanderControl.ContentArea>
</Bewise:ExpanderControl>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
i need to access LongList inside ListBoxName.I needed this LongList to get the selected item and itemSource or to add item to the selecteditem of the list
You could use the VisualTreeHelper class in order to access elements within.
Example!
I have this xaml in windows phone 8.1.
My page data context is binded to a ViewModel, i.e. VM.
And My listView is binded to Items of ViewModel.
And the text in each list view item is binded to Text of Items of ViewModel.
<Page DataContext="{Binding VM}">
<ListView ItemsSource="{Binding Items}">
<ListView.ItemTemplate>
<DataTemplate>
<TextBox Text="{Binding Text}"/>
<TextBox Text="{Binding soemthing in VM}" />
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
</Page>
My question is how can I change the parent datacontext of my 2nd TextBox so that I can bind something in my ViewModel (not my ViewModel.Items)?
Thank you.
If you don't mind Element Binding,
<ListView ItemsSource="{Binding Items}">
<ListView.ItemTemplate>
<DataTemplate>
<TextBox Text="{Binding Text}"/>
<!-- Bind the DataContext directly to the whatever element you like, in this case the page, then the Text Binding is basically the DataContext.VM_Property -->
<TextBlock Text="{Binding DataContext.VM_Property}" DataContext="{Binding ElementName=page}" ></TextBlock>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
My datacontext has two properties: Items which is a collection and DetailsVisiblity which is enum of type Visiblity.
On the page I have a Listbox with ItemsSource="{Binding Entries}". Inside the DataTemplate, I can bind stuff to properties of Items, but how do I get access to DetailsVisiblity which is a property of DataContext?
DataContext has two properties: ObservableCollection<Item> Entries, and Visibility DetailsVisiblity. Item class has two properties: Title and Details.
Here is the view. How do I bind Visiblity of the second TextBlock to DetailsVisiblity property?
<ListBox ItemsSource="{Binding Items}">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel>
<TextBlock Text="{Binding Title}" />
<TextBlock Text="{Binding Details}" Visibility="{Binding ???}" />
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
You could name the ListBox and in the Binding you reference it with ElementName, and in Path you use DataContext.DetailsVisibility
<ListBox x:Name="listBox" ItemsSource="{Binding Items}">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<TextBlock Text="{Binding Title}" />
<TextBlock Text="{Binding Details}"
Visibility="{Binding ElementName=listBox,
Path=DataContext.DetailsVisibilty}" />
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
Suppose I have a user control which datacontext is bound to a VM. This VM has a property for a list MyList.
Inside this user control I have a ComboBox, I want to set following kind of xaml
<Grid x:Name="LayoutRoot" Background="White">
<StackPanel HorizontalAlignment="Stretch">
<sdk:DataGrid ItemsSource="{Binding YourList}" IsReadOnly="True" AutoGenerateColumns="False" >
<sdk:DataGrid.Columns>
<sdk:DataGridTextColumn Header="Name" Binding="{Binding Name}" />
<!-- ...... -->
<sdk:DataGridTemplateColumn Header="User" >
<sdk:DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<ComboBox ItemsSource="{Binding ElementName=LayoutRoot, Path=DataContext.MyList}" DisplayMemberPath="Value" SelectedValuePath="Key" SelectedValue="{Binding UserID}" ></ComboBox>
</DataTemplate>
</sdk:DataGridTemplateColumn.CellTemplate>
</sdk:DataGridTemplateColumn>
</sdk:DataGrid.Columns>
</sdk:DataGrid>
</StackPanel>
</Grid>
but it is not working.
How to resolve this problem?
This worked form me. This was the ItemSource for a ComboBox that was within a DataGrid:
ItemsSource="{Binding RelativeSource={RelativeSource AncestorType=sdk:DataGrid},
Path=DataContext.Teams}">
Are you trying to get to the main VM from within the UserControl? take a look at this solution. http://weblogs.asp.net/dwahlin/archive/2009/08/20/creating-a-silverlight-datacontext-proxy-to-simplify-data-binding-in-nested-controls.aspx
