public enum MessageType

we can call it like
private void Button_Close(object sender, RoutedEventArgs e)
{
bool? Result = new MessageBoxCustom("Are you sure, You want to close
application ?", MessageType.Confirmation, MessageButtons.YesNo).ShowDialog();
if (Result.Value)
{
Application.Current.Shutdown();
}
}

Consider using this package that has the following extra benefit features:
Custom styles for border window, message foreground and background, title foreground and background, border, etc
Button to copy message box details to clipboard
Scrollable message box content
Message content is .NET UIElement which can host any content

WPF - Getting position of a control keeps returning {0;0}

I'm trying to get the positions of controls (buttons) but it keeps returning {0;0}. I'm sure there's an explanation for this, but I can't figure out why this happens.
I want the position of the control, relative to the window or a certain container. My buttons are arranged in another grid. Taking the margins of these buttons would just give 0,0 since they're all inside grid cells.
What I tried:
- var point = btnTest.TransformToAncestor(mainGrid).Transform(new Point());
- UIElement container = VisualTreeHelper.GetParent(btnTest) as UIElement;
Point relativeLocation = btnTest.TranslatePoint(new Point(0, 0), mainGrid);
I tried this with a grid as a parent and with a canvas. Everything I try gives me {0,0}. When I change the new Point parameters, the position does change. It stays the same as the parameters.
Small part of my XAML:
<Grid x:Name="mainGrid">
<Grid Name="buttonGrid" Margin="105,64,98.4,97.8">
<Grid.RowDefinitions>
<RowDefinition Height="25"/>
<RowDefinition Height="25"/>
<RowDefinition Height="25"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="50"/>
<ColumnDefinition Width="50"/>
<ColumnDefinition Width="50"/>
</Grid.ColumnDefinitions>
<Button x:Name="btnTest" Grid.Row="0" Grid.Column="0" Content="Button" HorizontalAlignment="Left" Margin="0,0,0,0" VerticalAlignment="Top" Width="26" Height="29"/>
<Button x:Name="btnTest2" Grid.Row="1" Grid.Column="1" Content="Button" HorizontalAlignment="Left" Margin="0,0,0,0" VerticalAlignment="Top" Width="26" Height="29"/>
</Grid>
</Grid>

Your code works perfectly fine, it is the timing that is the issue. The UI elements must be drawn before the position can be retrieved.
The code sample below shows the point extraction running in the constructor with the result 0,0 and then running in the loaded event which returns the desired result 84,78.
<Window x:Class="WpfApp7.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="450" Width="800" Loaded="Window_Loaded">
<Grid x:Name="mainGrid">
<Button x:Name="btnTest" Content="TileButton" HorizontalAlignment="Left" Margin="84,78,0,0" VerticalAlignment="Top" Width="109" Height="103"/>
</Grid>
public MainWindow()
{
InitializeComponent();
GetPoint();
}
private void Window_Loaded(object sender, RoutedEventArgs e)
{
GetPoint();
}
private void GetPoint()
{
var point = btnTest.TransformToAncestor(mainGrid).Transform(new Point());
UIElement container = VisualTreeHelper.GetParent(btnTest) as UIElement;
Point relativeLocation = btnTest.TranslatePoint(new Point(0, 0), mainGrid);
MessageBox.Show($"X = {relativeLocation.X} Y = {relativeLocation.Y}");
}

Scroll to object on Button click (C# /Xaml)

Is there a way to have a xaml page scroll to a particular object on a button click? For example, I have three buttons at the top of my page. I would like each button to move the scrollviewer to the top, middle, and bottom section of the page. How can I make this happen? Thanks!

I try to create the Xaml and to solve the problem. This is my solution.
This is the Xaml code.
<Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
<Grid.RowDefinitions>
<RowDefinition Height="100"></RowDefinition>
<RowDefinition Height="*"></RowDefinition>
</Grid.RowDefinitions>
<Button HorizontalAlignment="Left" Content="Top" Click="Button_Click" ></Button>
<Button HorizontalAlignment="Center" Content="Center" Click="Button_Click_1" ></Button><Button Content="Botton" HorizontalAlignment="Right" Click="Button_Click_2" ></Button>
<ScrollViewer Grid.Row="1" Name="MyScrollViewer" MaxZoomFactor="9">
<StackPanel>
<TextBlock Name="TextBlock" Height="20"> </TextBlock>
<Rectangle Height="300" Width="100" Fill="BlanchedAlmond"></Rectangle>
<Rectangle Height="300" Width="100" Fill="Blue"></Rectangle>
<Rectangle Height="300" Width="100" Fill="BlueViolet"></Rectangle>
<Rectangle Height="300" Width="100" Fill="Chartreuse"></Rectangle>
<Rectangle Height="300" Width="100" Fill="Crimson"></Rectangle>
</StackPanel>
</ScrollViewer>
</Grid>
And this is the .cs Code
private void Button_Click(object sender, RoutedEventArgs e)
{
MyScrollViewer.ScrollToVerticalOffset(0);
}
private void Button_Click_1(object sender, RoutedEventArgs e)
{
var scrollableHeight = MyScrollViewer.ScrollableHeight;
var height= scrollableHeight / 2;
MyScrollViewer.ScrollToVerticalOffset(height);
}
private void Button_Click_2(object sender, RoutedEventArgs e)
{
MyScrollViewer.ScrollToVerticalOffset(MaxHeight);
}
}

How to get a Grid to raise MouseDown events when no UIElemets in cells clicked?

I observe Mouse.MouseDown and PreviewMouseLeftButtonDown are only raised when the mouse is clicked in a cell that contains a UIElement, e.g.:
XAML
<Window xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" x:Class="WpfApplication5.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" Width="300" Height="300">
<Grid Mouse.MouseDown="Grid_MouseDown" PreviewMouseLeftButtonDown="Grid_PreviewMouseLeftButtonDown">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="100"/>
<ColumnDefinition Width="100"/>
<ColumnDefinition Width="100"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="100"/>
<RowDefinition Height="100"/>
<RowDefinition Height="100"/>
</Grid.RowDefinitions>
<Rectangle Grid.Column="2" Grid.RowSpan="2" Fill="Red"/>
</Grid>
</Window>
Code-behind
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
}
private void Grid_PreviewMouseLeftButtonDown(object sender, MouseButtonEventArgs e)
{
Debug.WriteLine("PreviewMouseLeftButtonDown raised!");
}
private void Grid_MouseDown(object sender, MouseButtonEventArgs e)
{
Debug.WriteLine("MouseDown raised!");
}
}
The lines are only written to Debug when the red rectangle is clicked. How can I get the events, or at least one of them, to be raised the grid contains nothing?

I do not know the cause of the issue, but as a workaround giving the Grid a background, even Transparent, seems to make the events be raised!
<Grid Background="Transparent" Mouse.MouseDown="Grid_MouseDown" PreviewMouseLeftButtonDown="Grid_PreviewMouseLeftButtonDown">

Grid.Column="0"

Left=? /> < !-- How to set "LvCol_11" in here? -->
</Grid>`

It seems like that you want to set the grid.row as property which is used when the button click.
Maybe you can try this...
GridSplitterControl.xaml.cs
private void UI_Loaded(object sender, RoutedEventArgs e)
{
if (sender is GridSplitter)
{
Grid ParentGrid = this.ParentOfType<Grid>();
SetLocation(ParentGrid);
}
}
public void SetLocation(Grid p_Layout)
{
int index = Grid.GetColumn(this);
ColumnDefinition ColLocation = p_Layout.ColumnDefinitions[index];
ColLocation.MinWidth = 10;
Left = ColLocation;
}
Becarefully, besure your element's parent(Up one level) is grid.
If parent is stackPanel, border, or rectangle, it will be not working, maybe.
