Instead of setting the Width you can completely hide the row headers by setting on the DataGrid 

    HeadersVisibility=&quot;Column&quot;

Use the `RowHeaderWidth` property:

    &lt;my:DataGrid RowHeaderWidth=&quot;0&quot; AutoGenerateColumns=&quot;False&quot; Name=&quot;dataGrid1&quot; /&gt;

Note that you can also specify a style or template for it also, should you decide you really do like it and want to keep it because you can do something cool with it.

**To remove the Row header(Gray field) in Datagrid in WPF**

    &lt;DataGrid x:Name=&quot;TrkDataGrid&quot; HeadersVisibility=&quot;Column&quot;&gt;
    &lt;/DataGrid&gt;

**To remove or hide the Column Header in DataGrid WPF**

    &lt;DataGrid x:Name=&quot;TrkDataGrid&quot; HeadersVisibility=&quot;Row&quot;&gt;
    &lt;/DataGrid&gt;

**To remove or hide both Column and Row Header in DataGrid WPF**

    &lt;DataGrid x:Name=&quot;TrkDataGrid&quot; HeadersVisibility=&quot;None&quot;&gt;
    &lt;/DataGrid&gt;

Had the same problem.

Looks like the RowHeaderWidth is not supported in XAML BUT you can specify in the code behind right after the bind and it takes out that crappy selector column.

grdName.RowHeaderWidth = 0



What does the word &quot;dead beef&quot; mean? I read it from a interview question. It has something to do with ipv6. I figured it could be a random hex number used for examples, like &quot;The quick brown fox jumps over the lazy dog&quot;.
 
Is my understanding correct? Or it has more significant meaning?

I&#39;m using the WPF DataGrid control to show some details and a select button, and I don&#39;t need the gray selector column down the left-hand side. It&#39;s also ruining the beauty of my design.

Is there a way to remove it, or how can I style it to match if not?

Despite some posts on this forum and others i cannot find something that tells me how to set the focus on a `TextBox`.

I have a userControl with many labels and textBoxes.  When the form is loaded I want the a particular textBox to have the focus.

I have set the tabIndex but that didn&#39;t seem to work.

Any suggestions?

Set the focus on a textbox in xaml wpf

I actually don&#39;t like #region in my code. *BUT* for some reason call me crazy, I would like to have them in my XAML. I would like whole sections to have a #region-like thing and collapse them (e.g. my &amp;lt;Window.CommandBindings&gt;, &amp;lt;Grid.*Definitions&gt;, &amp;lt;Menu&gt;, &amp;lt;Toolbar&gt;, etc..

Does this exist? If not, how about &amp;lt;RegionCollapse&gt;

#region in XAML

I am try to set the caret/cursor position to the **end** of the string value in my WPF textbox when I open my window for the first time.  I use the FocusManager to set the focus on my textbox when my window opens.

Nothing seems to work.  Any ideas?

Note, I am using the MVVM pattern, and I included only a portion of the XAML from my code.

    &lt;Window 
        FocusManager.FocusedElement=&quot;{Binding ElementName=NumberOfDigits}&quot;
        Height=&quot;400&quot; Width=&quot;800&quot;&gt;

        &lt;Grid&gt;
            &lt;Grid.ColumnDefinitions&gt;
                &lt;ColumnDefinition/&gt;
            &lt;/Grid.ColumnDefinitions&gt;
            &lt;Grid.RowDefinitions&gt;
                &lt;RowDefinition/&gt;
                &lt;RowDefinition/&gt;
            &lt;/Grid.RowDefinitions&gt;
    
            &lt;TextBox Grid.Column=&quot;0&quot; Grid.Row=&quot;0&quot; 
                     x:Name=&quot;NumberOfDigits&quot;
                     IsReadOnly=&quot;{Binding Path=IsRunning, Mode=TwoWay}&quot;
                     VerticalContentAlignment=&quot;Center&quot;
                     Text=&quot;{Binding Path=Digits, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}&quot;/&gt;
            &lt;Button Grid.Column=&quot;0&quot; Grid.Row=&quot;1&quot; 
                     Margin=&quot;10,0,10,0&quot;
                     IsDefault=&quot;True&quot;
                     Content=&quot;Start&quot; 
                     Command=&quot;{Binding StartCommand}&quot;/&gt;
        &lt;/Grid&gt;

Set the caret/cursor position to the end of the string value WPF textbox

I have a Button and a TextBox in my WPF app. How can I make the Button not enabled until the user enters some text in the TextBox?

Disable button in WPF?

I want to add a simple (at least I thought it was) behaviour to my WPF `TextBox`.

When the user presses Escape I want the `TextBox` he is editing to have the text it had when the user started editing, AND I want to remove the focus from the `TextBox`.

I don&#39;t have any problem setting the text for the value it had in the beginning of the edit.

The problem is to remove the focus of the element. I don&#39;t want to move the focus to any other component, I just want the `TextBox` to lose focus. Will I have to have an invisible element to set the focus so my `TextBox` can lose focus?

I have a DataGrid with first column as text column and second column as CheckBox column. What I want is, if I click the check box. It should get checked.&lt;br/&gt;&lt;br/&gt;
But, it takes two click to get selected, for first click the cell is getting selected, for the second clicks the check box is getting checked. How to make the check box to get checked/unchecked with a single click.

I&#39;m using WPF 4.0. Columns in the DataGrid are AutoGenerated.

I want to format my string binding as `Amount is X` where `X` is a property bound to a label.

I&#39;ve seen many examples but the following doesn&#39;t work:

    &lt;Label Content=&quot;{Binding Path=MaxLevelofInvestment, 
       StringFormat=&#39;Amount is {0}&#39;}&quot; /&gt;

I&#39;ve also tried these combinations:

    StringFormat=Amount is {0}
    StringFormat=&#39;Amount is {}{0}&#39;
    StringFormat=&#39;Amount is \{0\}&#39;

I even tried changing the binding property&#39;s datatype to `int`, `string`and `double`. Nothing seems to work. This is a very common use case but doesn&#39;t seem to be supported.




WPF StringFormat on Label Content

I am using a DataGrid in row selection mode (i.e., `SelectionUnit=&quot;FullRow&quot;`). I simply want to remove the border that is being placed around the current cell when the user highlights a row in order to have true full row selection (and no cell level selection). I don&#39;t mind the notion of the grid maintaining the current cell, I just want to remove that pesky current cell border, perhaps by changing the style of the current cell. What is the easiest way to do this?

Disable DataGrid current cell border in FullRow selection mode

   I have tried this method..   without luck..

     &lt;Style TargetType=&quot;{x:Type DataGridRow}&quot;&gt;
      &lt;Style.Triggers&gt;
          &lt;Trigger Property=&quot;ItemsControl.AlternationIndex&quot; Value=&quot;0&quot;&gt;
              &lt;Setter Property=&quot;Foreground&quot; Value=&quot;Red&quot; /&gt;
         &lt;/Trigger&gt;
      &lt;/Style.Triggers&gt;
    &lt;/Style&gt;

Is there a way to get the row Index?
I have even tried

    &lt;DataTrigger Binding=&quot;{Binding AlternationIndex}&quot; Value=&quot;0&quot;&gt;
        &lt;Setter Property=&quot;Foreground&quot; Value=&quot;Green&quot;&gt;&lt;/Setter&gt;
    &lt;/DataTrigger&gt;

wpf datagrid alternate row coloring

I have two simple Model classes and a ViewModel...

    public class GridItem
    {
        public string Name { get; set; }
        public int CompanyID { get; set; }
    }

    public class CompanyItem
    {
        public int ID { get; set; }
        public string Name { get; set; }
    }

    public class ViewModel
    {
        public ViewModel()
        {
            GridItems = new ObservableCollection&lt;GridItem&gt;() {
                new GridItem() { Name = &quot;Jim&quot;, CompanyID = 1 } };

            CompanyItems = new ObservableCollection&lt;CompanyItem&gt;() {
                new CompanyItem() { ID = 1, Name = &quot;Company 1&quot; },
                new CompanyItem() { ID = 2, Name = &quot;Company 2&quot; } };
        }

        public ObservableCollection&lt;GridItem&gt; GridItems { get; set; }
        public ObservableCollection&lt;CompanyItem&gt; CompanyItems { get; set; }
    }

...and a simple Window:

    &lt;Window x:Class=&quot;DataGridComboBoxColumnApp.MainWindow&quot;
            xmlns=&quot;http://schemas.microsoft.com/winfx/2006/xaml/presentation&quot;
            xmlns:x=&quot;http://schemas.microsoft.com/winfx/2006/xaml&quot;
            Title=&quot;MainWindow&quot; Height=&quot;350&quot; Width=&quot;525&quot;&gt;
        &lt;Grid&gt;
            &lt;DataGrid AutoGenerateColumns=&quot;False&quot; ItemsSource=&quot;{Binding GridItems}&quot; &gt;
                &lt;DataGrid.Columns&gt;
                    &lt;DataGridTextColumn Binding=&quot;{Binding Name}&quot; /&gt;
                    &lt;DataGridComboBoxColumn ItemsSource=&quot;{Binding CompanyItems}&quot;
                                        DisplayMemberPath=&quot;Name&quot;
                                        SelectedValuePath=&quot;ID&quot;
                                        SelectedValueBinding=&quot;{Binding CompanyID}&quot; /&gt;
                &lt;/DataGrid.Columns&gt;
            &lt;/DataGrid&gt;
        &lt;/Grid&gt;
    &lt;/Window&gt;

The ViewModel is set to the MainWindow&#39;s `DataContext` in App.xaml.cs:

    public partial class App : Application
    {
        protected override void OnStartup(StartupEventArgs e)
        {
            base.OnStartup(e);

            MainWindow window = new MainWindow();
            ViewModel viewModel = new ViewModel();

            window.DataContext = viewModel;
            window.Show();
        }
    }

As you can see I set the `ItemsSource` of the DataGrid to the `GridItems` collection of the ViewModel. This part works, the single Grid line with Name &quot;Jim&quot; is displayed.

I also want to set the `ItemsSource` of the ComboBox in every row to the `CompanyItems` collection of the ViewModel. This part does not work: The ComboBox remains empty and in the Debugger Output Window I see an error message:

&gt; System.Windows.Data Error: 2 : Cannot
&gt; find governing FrameworkElement or
&gt; FrameworkContentElement for target
&gt; element.
&gt; BindingExpression:Path=CompanyItems;
&gt; DataItem=null; target element is
&gt; &#39;DataGridComboBoxColumn&#39;
&gt; (HashCode=28633162); target property
&gt; is &#39;ItemsSource&#39; (type &#39;IEnumerable&#39;)

I believe that WPF expects `CompanyItems` to be a property of `GridItem` which is not the case, and that&#39;s the reason why the binding fails.

I&#39;ve already tried to work with a `RelativeSource` and `AncestorType` like so:

    &lt;DataGridComboBoxColumn ItemsSource=&quot;{Binding CompanyItems, 
        RelativeSource={RelativeSource Mode=FindAncestor,
                                       AncestorType={x:Type Window}}}&quot;
                            DisplayMemberPath=&quot;Name&quot;
                            SelectedValuePath=&quot;ID&quot;
                            SelectedValueBinding=&quot;{Binding CompanyID}&quot; /&gt;

But that gives me another error in the debugger output:

&gt; System.Windows.Data Error: 4 : Cannot
&gt; find source for binding with reference
&gt; &#39;RelativeSource FindAncestor,
&gt; AncestorType=&#39;System.Windows.Window&#39;,
&gt; AncestorLevel=&#39;1&#39;&#39;.
&gt; BindingExpression:Path=CompanyItems;
&gt; DataItem=null; target element is
&gt; &#39;DataGridComboBoxColumn&#39;
&gt; (HashCode=1150788); target property is
&gt; &#39;ItemsSource&#39; (type &#39;IEnumerable&#39;)

**Question: How can I bind the ItemsSource of the DataGridComboBoxColumn to the CompanyItems collection of the ViewModel? Is it possible at all?**

Thank you for help in advance!
