I have a slider with minimum 0 and max 100.
I have a popup window that is visible when I mouseover the slider.
Currently, I binded the popup with the slider value.
What I want is:
When I move the mouse over the slider, I want to see value that suppose to be in that position.
For example:
My XAML:
<Window x:Class="WPFMavka.VideoPlayer"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:WPFMavka"
Title="MainWindow" WindowStyle="None" Width="1920" Height="1080" WindowState="Maximized" KeyboardNavigation.TabNavigation="None" Closing="Window_Closing">
<Grid Name="tst">
<local:MetroSlider x:Name="bla" MouseMove="Rectangle_MouseMove" MouseLeave="Rectangle_MouseLeave" IsMoveToPointEnabled="True" HorizontalAlignment="Left" Width="542" VerticalAlignment="Top" Margin="116,839,0,0" Value="0" Style="{DynamicResource SliderStyle1}" Height="66" AutoToolTipPrecision="0" AutoToolTipPlacement="TopLeft"/>
<Popup Name="floatingTip" AllowsTransparency="True" Placement="Relative" PlacementTarget="{Binding ElementName=bla}">
<Border BorderBrush="Black" BorderThickness="1" Padding="4">
<TextBlock Text="{Binding ElementName=bla, Path=Value}"></TextBlock>
</Border>
</Popup>
</Grid>
</Window>
My Code-Behind:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Controls.Primitives;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Shapes;
namespace WPFMavka
{
/// <summary>
/// Interaction logic for VideoPlayer.xaml
/// </summary>
public partial class VideoPlayer : Window
{
public VideoPlayer()
{
InitializeComponent();
}
private void Window_Closing(object sender, System.ComponentModel.CancelEventArgs e)
{
Environment.Exit(1);
}
private void Rectangle_MouseMove(object sender, MouseEventArgs e)
{
if (!floatingTip.IsOpen) { floatingTip.IsOpen = true; }
Point currentPos = e.GetPosition(bla);
floatingTip.HorizontalOffset = currentPos.X-14;
floatingTip.VerticalOffset = -32;
}
private void Rectangle_MouseLeave(object sender, MouseEventArgs e)
{
floatingTip.IsOpen = false;
}
}
}
Found a better solution - changing the TextBlock
onMouseOver
the slide > I get the current position of mouse on the slider and then uses .ValueFromPoint()
XAML:
<Window x:Class="WPFMavka.VideoPlayer"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:WPFMavka"
Title="MainWindow" WindowStyle="None" Width="1920" Height="1080" WindowState="Maximized" KeyboardNavigation.TabNavigation="None" Closing="Window_Closing">
<Grid Name="tst">
<local:MetroSlider x:Name="slider" MouseMove="slider_MouseMove" MouseLeave="slider_MouseLeave" IsMoveToPointEnabled="True" HorizontalAlignment="Left" Width="746" VerticalAlignment="Top" Margin="330,851,0,0" Value="0" Style="{DynamicResource SliderStyle1}" Height="44"/>
<Popup Name="floatingTip" AllowsTransparency="True" Placement="Relative" PlacementTarget="{Binding ElementName=slider}">
<Border Name="floatingTipBorder" BorderBrush="Black" BorderThickness="1" Padding="4">
<TextBlock Name="sliderTextBlock"/>
</Border>
</Popup>
</Grid>
</Window>
Code-Behind:
private void slider_MouseMove(object sender, MouseEventArgs e)
{
if (!floatingTip.IsOpen) { floatingTip.IsOpen = true; }
Point currentPos = e.GetPosition(slider);
Track _track = slider.Template.FindName("PART_Track", slider) as Track;
sliderTextBlock.Text = _track.ValueFromPoint(currentPos).ToString();
floatingTip.HorizontalOffset = currentPos.X -(floatingTipBorder.ActualWidth / 2);
floatingTip.VerticalOffset = -32;
}
private void slider_MouseLeave(object sender, MouseEventArgs e)
{
floatingTip.IsOpen = false;
}
You can use AttachedCommand
s for this. You can download the library from here . So in this case you could do something like:
<Window x:Class="WPFMavka.VideoPlayer"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:WPFMavka"
xmlns:AttachedCommand="clr-namespace:AttachedCommandBehavior;assembly=AttachedCommandBehavior"
Title="MainWindow"
WindowStyle="None"
Width="1920"
Height="1080"
WindowState="Maximized"
KeyboardNavigation.TabNavigation="None"
Closing="Window_Closing">
<Grid Name="tst">
<local:MetroSlider x:Name="bla"
MouseMove="Rectangle_MouseMove"
MouseLeave="Rectangle_MouseLeave"
IsMoveToPointEnabled="True"
HorizontalAlignment="Left"
Width="542" VerticalAlignment="Top"
Margin="116,839,0,0"
Value="0"
Style="{DynamicResource SliderStyle1}"
Height="66" AutoToolTipPrecision="0"
AutoToolTipPlacement="TopLeft"
AttachedCommand:CommandBehavior.Event="MouseMove"
AttachedCommand:CommandBehavior.Command="{Binding UpdateCurrentMouseTimeCommand}"
AttachedCommand:CommandBehavior.CommandParameter="{Binding ElementName=Bla, Path=Value}"/>
<Popup Name="floatingTip" AllowsTransparency="True"
Placement="Relative"
PlacementTarget="{Binding ElementName=bla}">
<Border BorderBrush="Black" BorderThickness="1" Padding="4">
<TextBlock Text="{Binding CurrentMouseTime, NotifyOnSourceUpdated=True, Mode=OneWay}" />
</Border>
</Popup>
</Grid>
</Window>
Then in your command UpdateCurrentMouseTimeCommand
you set the property
private string currentMouseTime = String.Empty;
public string CurrentMouseTime
{
get { return value; }
set
{
if (currentMouseTime == value)
return;
currentMouseTime = value;
OnPropertyChanged("CurrentMouseTime");
}
}
Where the containing class must implement INotifyPropertyChanged
.
I hope this helps.
