Wpf set all columns to have the same default width - c#

I'm trying to list a lot of items in a grid and i dont want to have to repeat "ColumnDefinition Width=40" from here on to infinity as i will need to add more TextBoxes with bindings.
Is there any way that i can set all columns to have width 40 so that i don't have to list everything?
I have tried using a UniformGrid, but i couldn't make it work properly.
<ListView ItemsSource="{Binding TreeViewData}">
<ListView.Resources>
<DataTemplate
DataType="{x:Type model:Character}">
<Grid >
<Grid.ColumnDefinitions>
<ColumnDefinition Width="50"/>
<ColumnDefinition Width="40"/>
<ColumnDefinition Width="40"/>
<ColumnDefinition Width="40"/>
<ColumnDefinition Width="40"/>
<ColumnDefinition Width="40"/>
</Grid.ColumnDefinitions>
<TextBlock Text="{Binding Type}" />
<TextBox Grid.Column="1" Text="{Binding MaxHealth}" />
<TextBox Grid.Column="2" Text="{Binding Health}" />
<TextBox Grid.Column="3" Text="{Binding RegenerationSpeed}" />
<CheckBox Grid.Column="4" IsChecked="{Binding Invincible}" Margin="10,3,0,0"/>
</Grid>
</DataTemplate>
</ListView.Resources>
</ListView>

It's probably more work than its worth, since you can't directly apply a Style for a grid's ColumnDefinitions. I would probably just set a resource with your value (40) and use that. At least you would only need to change the value one place, if you decided to change the value to 50 or something. You can do that in XAML (in your ResourceDictionary if you have several controls etc. or the Window.Resources, whatever) like this:
<Window.Resources>
<GridLength x:Key="stdWidth">40</stdWidth>
</Window.Resources>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="{StaticResource stdWidth}" />
</Grid.ColumnDefinitions>
</Grid>

Cannot align textboxes inside grid properly among themselves

I have the following DataTemplate where inside is a Grid with a 'TextBlock' and TextBox that I want to align to the center:
<DataTemplate x:Key="OneSettingsEntryTemplate" DataType="{x:Type templateHelper:InputText}">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="0"
Style="{StaticResource StandardTextBlocksStyle}"
Text="{Binding Text, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"/>
<TextBox Grid.Column="1"
Style="{StaticResource DefaultTextBoxesStyle}"
Text="{Binding Content, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"/>
</Grid>
</DataTemplate>
In one of my UserControls I have the following code where I use the Template:
<StackPanel DataContext="{Binding ElementName=ControlForProjectSettings, Path=ViewModel}"
HorizontalAlignment="Center">
<TextBlock Style="{StaticResource HeadingTextBlocksStyle}"
Text="Project settings"/>
<ListView Background="#DAE7F5"
ItemsSource="{Binding ProjectSettingEntries}"
ItemTemplate="{StaticResource OneSettingsEntryTemplate}">
</ListView>
</StackPanel>
When I run my application and display some items, the last item has a longer text and therefore the TextBox flips to the right. Application Image
I tried playing around with the HorizontalAlignment and VerticalAlignment properties inside the Grid or also using a DockPanel instead of a Grid but couldn't find a solution. Any ideas?
Thanks to this source: WPF share column width between separate grids I solved my problem.
I added the IsSharedSizeScope to my Grid and the SharedSizeGroup property to my columns.
<Grid IsSharedSizeScope="True">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" SharedSizeGroup="A"/>
<ColumnDefinition Width="Auto" SharedSizeGroup="A"/>
</Grid.ColumnDefinitions>

Align controls correctly when using ItemsControl in WPF

Can someone tell me how to align and resize controls correctly when using the ItemsControl.
I want to have a description on the left and a TextBox on the right for multiple fields which are defined in an ObservableCollection to end up with something like:
First Name: [FirstNameTextBox]
Last Name: [LastNameTextBox]
Date of Birth: [DobTextBox]
but instead I'm getting this:
First Name: [FirstNameTextBox]
Last Name: [LastNameTextBox]
Date of Birth: [DobTextBox]
I want all the textbox to be aligned based on the largest <TextBlock>. If this was done directly in a <Grid> control, it would be straight forward as all controls are directly in the grid and you would just have the following columns definition defined
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition/>
</Grid.ColumnDefinitions>
I thought I could use the SharedSizeGroup property in the <Grid> but it still doesn't resize correctly. Instead it only displays the <TextBlock> stretch across the <Grid>.
Here's my code:
<Grid Grid.IsSharedSizeScope="True" Grid.Row="1">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" SharedSizeGroup="Labels" />
<ColumnDefinition Width="*" SharedSizeGroup="InputControls" />
</Grid.ColumnDefinitions>
<ItemsControl Grid.Row="1" ItemsSource="{Binding SelectedTemplate.Fields}">
<ItemsControl.ItemTemplate>
<DataTemplate>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition SharedSizeGroup="Labels"/>
<ColumnDefinition SharedSizeGroup="InputControls"/>
</Grid.ColumnDefinitions>
<TextBlock Text="{Binding Path=Label}" Grid.Column="0" Margin="5"
VerticalAlignment="Center" Background="Red" />
<TextBox Text="{Binding Path=Value}" Grid.Column="1" Margin="5"
VerticalAlignment="Center" Background="Blue" />
</Grid>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</Grid>
Any idea how I can resolve this?
Thanks.
UPDATE1: I cannot get this to work as I need it to. This is what I've got so far:
<Grid Grid.Row="1" Background="Purple">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" SharedSizeGroup="Overall" />
</Grid.ColumnDefinitions>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition SharedSizeGroup="Labels" Width="Auto" />
<ColumnDefinition SharedSizeGroup="InputControls" Width="*" />
</Grid.ColumnDefinitions>
<ItemsControl ItemsSource="{Binding SelectedTemplate.Fields}"
Background="Yellow"
Grid.IsSharedSizeScope="True">
<ItemsControl.ItemTemplate>
<DataTemplate>
<Grid Background="Green">
<Grid.ColumnDefinitions>
<ColumnDefinition SharedSizeGroup="Labels"/>
<ColumnDefinition SharedSizeGroup="InputControls"/>
</Grid.ColumnDefinitions>
<TextBlock Text="{Binding Path=Label}"
Grid.Column="0"
Margin="5"
VerticalAlignment="Center"/>
<TextBox Text="{Binding Path=Name}"
Grid.Column="1"
Margin="5"
VerticalAlignment="Center"/>
</Grid>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</Grid>
This ends up displaying my layout this way:
As you can see, my TextBox are correctly aligned based on the largest TextBlock but my ItemsControls is not stretched all the way across. I guess that makes sense as it is within the same grid where the ColumnDefinitions are defined.
Now, if I move the ColumnDefinitions' out this grid to the outer grid and remove all instances ofGrid.IsSharedSizeScope`, I guess the following:
Which once again is closer to what I need as my ItemsControl is now stretching all the way as I've set its Grid.ColumnSpan="2" and my TextBox are still aligned to the TextBlock and are stretching all the way across but the problem now is that the TextBlock should be smaller as the Column is set to Auto but they appear to behave as if the column was set to * and I guess I'm losing the purpose of using IsSharedSizeScope since it has been removed.
Now if I add IsSharedSizeScope="True" to the outer grid, I get the following result:
Again, this is close to what I want as my ItemsControl is stretched, my textboxes are also stretch but they are no longer aligned to the largest TextBlock.
Finally, if I add Grid.IsSharedSizeScope="True" to ItemsControl as originally suggested by #mm8,
<Grid Grid.Row="1" Background="Purple" Grid.IsSharedSizeScope="True">
<Grid.ColumnDefinitions>
<ColumnDefinition SharedSizeGroup="Labels" Width="Auto" />
<ColumnDefinition SharedSizeGroup="InputControls" Width="*" />
</Grid.ColumnDefinitions>
<Grid Grid.ColumnSpan="2" >
<ItemsControl ItemsSource="{Binding SelectedTemplate.Fields}"
Background="Yellow"
Grid.IsSharedSizeScope="True">
<ItemsControl.ItemTemplate>
<DataTemplate>
<Grid Background="Green">
<Grid.ColumnDefinitions>
<ColumnDefinition SharedSizeGroup="Labels"/>
<ColumnDefinition SharedSizeGroup="InputControls"/>
</Grid.ColumnDefinitions>
<TextBlock Text="{Binding Path=Label}"
Grid.Column="0"
Margin="5"
VerticalAlignment="Center"/>
<TextBox Text="{Binding Path=Name}"
Grid.Column="1"
Margin="5"
VerticalAlignment="Center"/>
</Grid>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</Grid>
<!--<TextBlock Text="Invoice Number" Grid.Column="0" Margin="5" VerticalAlignment="Center"/>
<TextBox Text="InvoiceNumber" Grid.Column="1" Margin="5" VerticalAlignment="Center"/>-->
</Grid>
I get the following:
Which brings me back to square one, though the definitions are different?
I need to achieve the following:
What am I doing wrong??
Thanks.
Try to set the Grid.IsSharedSizeScope property of the ItemsControl itself:
<ItemsControl Grid.Row="1" ItemsSource="{Binding SelectedBarcodeTemplate.Fields}"
Grid.IsSharedSizeScope="True">
Synchronizing the width of elements in an ItemsControl: https://joshsmithonwpf.wordpress.com/2008/09/06/synchronizing-the-width-of-elements-in-an-itemscontrol/
I eventually found the answer in the following article: WPF Tutorial - Grid Panel under the section: "How to share the width of a column over multiple grids".
As per article:
Columns and rows that participate in size-sharing do not respect Star sizing. In the size-sharing scenario, Star sizing is treated as Auto. Since TextWrapping on TextBlocks within an SharedSize column does not work you can exclude your last column from the shared size. This often helps to resolve the problem.
So my final XAML looks like this:
<Grid Grid.Row="1" Background="Purple" >
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition SharedSizeGroup="Labels" Width="Auto" />
<ColumnDefinition SharedSizeGroup="InputControls" Width="*" />
</Grid.ColumnDefinitions>
</Grid>
<ItemsControl ItemsSource="{Binding SelectedBarcodeTemplate.Fields}"
Background="Yellow"
Grid.IsSharedSizeScope="True">
<ItemsControl.ItemTemplate>
<DataTemplate>
<Grid Background="Green" ShowGridLines="True">
<Grid.ColumnDefinitions>
<ColumnDefinition SharedSizeGroup="Labels"/>
<ColumnDefinition />
</Grid.ColumnDefinitions>
<TextBlock Text="{Binding Path=Label}"
Grid.Column="0"
Margin="5"
VerticalAlignment="Center"/>
<TextBox Text="{Binding Path=Name}"
Grid.Column="1"
Margin="5"
VerticalAlignment="Center"
HorizontalAlignment="Stretch"/>
</Grid>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</Grid>
And the outcome now finally looks correct:
Hope this helps others!

Can't see last item in Listbox

I'm using the ReorderListBox (https://reorderlistbox.codeplex.com/) in my windows phone application. I've got a Wrapped Text in my ListItems. Unfortunately, when the text of my Item is too long (like >300 characters), I can't use the reorder-button of my listboxitem, because I can't scroll down to see the full item/text.
<rlb:ReorderListBox VerticalContentAlignment="Bottom" Grid.Row="1" Name="Artikelliste" ItemsSource="{Binding Articlelist.Liste, Mode=TwoWay}" >
<rlb:ReorderListBox.ItemTemplate>
<DataTemplate>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition/>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="1" VerticalAlignment="Center"
FontSize="30"
Text="{Binding Bezeichnung}" TextWrapping="Wrap" />
</Grid>
</DataTemplate>
</rlb:ReorderListBox.ItemTemplate>
</rlb:ReorderListBox>

Controls vertical alignment with grid on the left and right

I have a custom listbox with a label and a checkbox in each row. I would like to have the label on the far left and the checkbox on the far right.
approach:
<ListBox x:Name="lbFieldsreq" HorizontalAlignment="Left" Height="100" Margin="513,232,0,0" VerticalAlignment="Top" Width="100">
<ListBox.ItemTemplate>
<DataTemplate>
<Grid ShowGridLines="True">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<Label Content="{Binding name, Mode=OneWay}" Grid.Column="0" HorizontalAlignment="Left" />
<Label Grid.Column="1" HorizontalAlignment="Center" /> <!--Empty column -->
<CheckBox IsChecked="{Binding ticked ,Mode=OneWay}" Grid.Column="2" HorizontalAlignment="Right" />
</Grid>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
current look:
Thx
Your XAML is mostly fine. All you really need to do is to set the ListBox.HorizontalContentAlignment property to "Stretch". This basically forces each item in the collection to stretch to fill with entire Width of the related ListBoxItem. However, you could improve this further by setting the Grid.IsSharedSizeScope Attached Property to True. Setting this in conjunction with the SharedSizeGroup property enables us to ensure that the column Widths of each column of the DataTemplate are the same. Try this:
<ListBox x:Name="lbFieldsreq" HorizontalAlignment="Left" Height="100" ItemsSource="{Binding Items}" VerticalAlignment="Top" HorizontalContentAlignment="Stretch">
<ListBox.ItemTemplate>
<DataTemplate>
<Grid ShowGridLines="True" Grid.IsSharedSizeScope="True">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" SharedSizeGroup="LabelColumn" />
<ColumnDefinition Width="*" />
<ColumnDefinition Width="Auto" SharedSizeGroup="CheckBoxColumn" />
</Grid.ColumnDefinitions>
<Label Content="{Binding}" Grid.Column="0" HorizontalAlignment="Left" />
<!--Empty column -->
<Label Grid.Column="1" HorizontalAlignment="Center" />
<CheckBox Grid.Column="2" IsChecked="{Binding ticked, Mode=OneWay}" HorizontalAlignment="Right" />
</Grid>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>

Getting text from textblock defined in style

I have a style in my Silverlight 4 app. where I define column names in a grid, is it possible to get these text of the headers from an object with this style? In the code below, what I would like to get is the strings "foo" and "bar", from an object with this style applied.
</Grid>
<Grid
x:Name="m_Headers"
Visibility="Visible"
Grid.Row="1">
<Grid.ColumnDefinitions>
<ColumnDefinition
Width="{StaticResource DataColunmWidth}" />
<ColumnDefinition
Width="{StaticResource DataColunmWidth}" />
</Grid.ColumnDefinitions>
<TextBlock
Margin="3,0,0,0"
Text="foo"
Grid.Column="1" />
<TextBlock
Margin="3,0,0,0"
Text="bar"
Grid.Column="2" />
</Grid>
I don't think you can do this with pure XAML, you'd have to duplicate the templates or create a custom control which exposes the text values as dependency properties via the template.
The best solution I think is to set up bindings for your Grid headers and fill them using your ViewModel:
<Grid
x:Name="m_Headers"
Visibility="Visible"
Grid.Row="1">
<Grid.ColumnDefinitions>
<ColumnDefinition
Width="{StaticResource DataColunmWidth}" />
<ColumnDefinition
Width="{StaticResource DataColunmWidth}" />
</Grid.ColumnDefinitions>
<TextBlock
Margin="3,0,0,0"
Text="{Binding FooText}"
Grid.Column="1" />
<TextBlock
Margin="3,0,0,0"
Text="{Binding BarText}"
Grid.Column="2" />
</Grid>
