WPF Еditable Textbox in a Listbox

WPF Еditable Textbox in a Listbox - c#

I'm new to wpf, but even so I thought this is a trivial problem. So i have а listbox with 4 columns: file names, textbox, checkbox and a button. The buttons are working fine, but for some reason i can't use the textboxes - can't click them or write inside them.
Here is my xaml:
<ListBox Name="lbDocxFiles" HorizontalContentAlignment="Stretch" Margin="10,0" Grid.ColumnSpan="2" Grid.Row="2" SelectionChanged="lbDocxFiles_SelectionChanged">
<ListBox.ItemTemplate>
<DataTemplate>
<Grid Margin="0,2">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="30" />
<ColumnDefinition Width="70" />
<ColumnDefinition Width="50" />
</Grid.ColumnDefinitions>
<CheckBox x:Name="checkBox" Grid.Column="3" Content="" HorizontalAlignment="Center" VerticalAlignment="Center"/>
<TextBox x:Name="tbNodeID" IsReadOnly="False" AcceptsReturn="True" IsEnabled="True" Focusable="True" TextWrapping="Wrap" HorizontalAlignment="Right" Height="25" Width="90" Text="" VerticalAlignment="Center" Grid.ColumnSpan="1">
<TextBox.Style>
<Style TargetType="{x:Type TextBox}">
<Style.Triggers>
<Trigger Property="IsFocused" Value="True">
<Setter Property="IsReadOnly" Value="False" />
</Trigger>
</Style.Triggers>
</Style>
</TextBox.Style>
</TextBox>
<Button Grid.Column="2" Width="70" Height="25" Content="UPLOAD" Click="btnUpload_Click" Background="#FF70ECD5" BorderThickness="0" Foreground="White" />
<TextBlock Grid.Column="0" Text="{Binding fileTitle}"/>
</Grid>
</DataTemplate>
</ListBox.ItemTemplate>
I guess i'm doing something wrong, but can't find out why the texboxes are not editable. Any help will be appreciated!
Thanks in advance!

Refer the below code. It should work. There some UI layout issue.
<ListBox x:Name="lbDocxFiles" HorizontalContentAlignment="Stretch" >
<ListBox.ItemTemplate>
<DataTemplate>
<Grid >
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="90" />
<ColumnDefinition Width="70" />
<ColumnDefinition Width="50" />
</Grid.ColumnDefinitions>
<CheckBox x:Name="checkBox" Grid.Column="3" Content="Tets" HorizontalAlignment="Center" VerticalAlignment="Center"/>
<TextBox x:Name="tbNodeID" IsReadOnly="False" AcceptsReturn="True"
IsEnabled="True" Focusable="True" TextWrapping="Wrap" HorizontalAlignment="Right"
Height="25" Width="90" Text="" VerticalAlignment="Center" Grid.Column="1">
<TextBox.Style>
<Style TargetType="{x:Type TextBox}">
<Style.Triggers>
<Trigger Property="IsFocused" Value="True">
<Setter Property="IsReadOnly" Value="False" />
</Trigger>
<Trigger Property="IsFocused" Value="False">
<Setter Property="IsReadOnly" Value="True" />
</Trigger>
</Style.Triggers>
</Style>
</TextBox.Style>
</TextBox>
<Button Grid.Column="2" Width="70" Height="25" Content="UPLOAD"
Background="#FF70ECD5" BorderThickness="0" Foreground="White" />
<TextBlock Grid.Column="0" Text="{Binding MyProperty}"/>
</Grid>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
ObservableCollection<MyModel> lst = new ObservableCollection<MyModel>();
lst.Add(new MyModel() { MyProperty = "Hi" });
lbDocxFiles.ItemsSource = lst;
}
}
class MyModel
{
private string myVar;
public string MyProperty
{
get { return myVar; }
set { myVar = value; }
}
}

So i found a solution here that works. We set the FocusManager.FocusedElement property in style trigger:
<Window.Resources>
<Style x:Key="{x:Type ListBoxItem}" TargetType="{x:Type ListBoxItem}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ListBoxItem}">
<StackPanel FocusManager.FocusedElement="{Binding ElementName=MyTextBox}" Orientation="Horizontal">
<Grid Margin="0,2">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="100" />
<ColumnDefinition Width="100" />
<ColumnDefinition Width="30" />
</Grid.ColumnDefinitions>
<TextBlock Text="{Binding fileTitle}" Grid.Column="0" />
<TextBox Name="tbNodeID" Text="{Binding Details}" Height="25" Width="90" HorizontalAlignment="Right" Grid.Column="2" />
<Button Grid.Column="1" Width="70" Height="25" HorizontalAlignment="Right" Content="UPLOAD" Click="btnUpload_Click" Background="#FF70ECD5" BorderThickness="0" Foreground="White" />
<CheckBox x:Name="checkBox" Grid.Column="3" Content="" HorizontalAlignment="Right" VerticalAlignment="Center"/>
</Grid>
</StackPanel>
<ControlTemplate.Triggers>
<Trigger Property="Selector.IsSelected" Value="True">
<Setter TargetName="tbNodeID" Property="FocusManager.FocusedElement" Value="{Binding ElementName=tbNodeID}" />
</Trigger>
<Trigger Property="IsKeyboardFocused" Value="True">
<Setter TargetName="tbNodeID" Property="FocusManager.FocusedElement" Value="{Binding ElementName=tbNodeID}" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</Window.Resources>
<Grid>
<ListBox Name="myLB" SelectedIndex="{Binding MySelectedIndex}">
</ListBox> </Grid>
This not only makes my textbox editable, but also focus it when item from the listbox is clicked.

How do I access TextBox here I want to have the cursor focus on end of the textbox for that I have to have access to the textbox. How can it be done? Should It be done from code behind or from ViewModel?
I have tried TileNameTextBox.CaretIndex = TileNameTextBox.Text.Length;
and TileNameTextBox.Focus();
It is not working as I cannot access TileNameTextBox in code behind directly.
The DataContext set in code behind is like
DataContext = new ViewModel();

WPF listbox trigger on empty change default style

I have a part of code that makes it so every listbox in my application shows a message when empty.
<Style TargetType="ListBox" BasedOn="{StaticResource {x:Type ListBox}}">
<Style.Triggers>
<Trigger Property="HasItems" Value="False">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate>
<TextBlock FontSize="20" Foreground="{DynamicResource ValidationErrorBrush}"
TextAlignment="Center" Text="Geen data beschikbaar" Width="Auto" />
</ControlTemplate>
</Setter.Value>
</Setter>
</Trigger>
</Style.Triggers>
</Style>
When I run the application with it enabled (uncommended) the empty listbox indeed display the message.
But when they are filled the item template is wider than it should be.
This is an example where I use a listbox:
<ListBox x:Name="DataGridTraffic"
Grid.Row="1"
SnapsToDevicePixels="True"
ItemsSource="{Binding Path=TrafficJams}"
ScrollViewer.VerticalScrollBarVisibility="Hidden"
SelectedIndex="-1"
ItemTemplate="{DynamicResource TrafficJamDataTemplateShort}"
AlternationCount="2"
BorderThickness="0"
HorizontalContentAlignment="Stretch"
ItemContainerStyle="{DynamicResource MainListBoxStyle}" />
Does anyone have a clue on what is going on?
Edit:
The first image shows how it is when I enable the trigger.
The second shows the way it is supposed to be.
Edit:
Here is some more as asked for.
This is the Datatemplate for the same thing as the pictures.

I need to bind to tag in my DataTemplate. Tried through construnction "{Binding Path=Tag, RelativeSource={RelativeSource TemplatedParent}}", but it disn't bind, shows the empty text. What am I doing wrong?

You should know that TemplateBinding can be used only in ControlTemplate, not DataTemplate. So you can try something like this as a workaround:
<TextBlock TextBlock.FontSize="12" HorizontalAlignment="Left"
VerticalAlignment="Stretch" TextAlignment="Center" Margin="6,-2,0,0"
Text="{Binding Tag,
RelativeSource={RelativeSource AncestorType=RadioButton}}"/>

WPF how to detect listviewitem has been selected

I have DataTemplate for my ListView control, which contains few textblocks and a button. I want the button to be visible only when the item is selected.
Here's my DataTemplate code:
<ListView.ItemTemplate>
<DataTemplate>
<Grid Background="AliceBlue">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="300" />
<ColumnDefinition Width="*" />
<ColumnDefinition Width="90" />
</Grid.ColumnDefinitions>
<TextBlock HorizontalAlignment="Left" Margin="10,0,10,0"
VerticalAlignment="Center" FontFamily="Verdana" FontSize="16"
FontWeight="Black" Grid.Column="0" Text="{Binding name}"/>
<StackPanel Orientation="Horizontal" HorizontalAlignment="Center" Grid.Column="1">
<TextBlock FontFamily="Verdana" FontSize="10" Grid.Column="1"
VerticalAlignment="Center" HorizontalAlignment="Center"
Text="Number of Chapters: " />
<TextBlock FontFamily="Verdana" FontSize="12" Grid.Column="1"
VerticalAlignment="Center" HorizontalAlignment="Center"
Text="{Binding chaptersCount}" />
</StackPanel>
<Button HorizontalAlignment="Center" Height="50" Width="80" Content="Read"
Grid.Column="2" Visibility="Hidden" Click="Button_Click_3" Name="ReadButton"/>
</Grid>
</DataTemplate>
</ListView.ItemTemplate>
How can I do that?

You can achieve this with DataTrigger in DataTemplate which will check for IsSelected property of Templated parent:
<ListView.ItemTemplate>
<DataTemplate>
.....
<Button HorizontalAlignment="Center" Height="50"
Width="80" Content="Read"
Grid.Column="2" Visibility="Hidden" Name="ReadButton"/>
</Grid>
<DataTemplate.Triggers>
<DataTrigger Binding="{Binding IsSelected,
RelativeSource={RelativeSource Mode=TemplatedParent}}"
Value="True">
<Setter TargetName="ReadButton" Property="Visibility"
Value="Visible"/>
</DataTrigger>
</DataTemplate.Triggers>
</DataTemplate>
</ListView.ItemTemplate>

You need to slightly change your Button: A quick XAML way would be to add a Trigger on its Visibility to make it hidden when not selected (note: code written here, hopefully there's no typo):
<Button HorizontalAlignment="Center" Height="50" Width="80" Content="Read"
Grid.Column="2" Click="Button_Click_3" Name="ReadButton">
<Button.Style>
<Style TargetType="{x:Type Button}">
<Style.Triggers>
<DataTrigger Binding="{Binding Path=IsSelected, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type ListViewItem}}" Value="False">
<Setter Property="Visibility" Value="Visible" />
</DataTrigger>
</Style.Triggers>
</Style>
</Button.Style>
</Button>

Any suggestion to get me out of this warning would be highly appreciable!?

You should merge the Resource Dictionary (2nd snip) to where you use it (1st snip), follow the following example and you should be good to go:
Add this to your Grid node (could add it in any ancestor node of your Button):
<Grid.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary
Source="Resources/MyResourceDictionary.xaml">
</ResourceDictionary>
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Grid.Resources>
Some good links to read regarding Resources and Resource Dictionaries:

http://blogs.msdn.com/b/wpfsldesigner/archive/2010/06/03/creating-and-consuming-resource-dictionaries-in-wpf-and-silverlight.aspx

Looks like your'e not the only one who encountered such problem, and it sounds like some bug in the VS wpf designer.
However, Expression Blend 4 deals with this problem using a design time resource dictionary which helps resolving such resources.
The resource could not be resolved (VS 2010 RC)
