Why UserControl without XAML controls do not inherit properties? - c#

I had a working user control done in WPF in XAML. Now I have removed the XAML and created the usercontrol with code because I need to inherit from this control. Previosuly I had code like this one on the code using the control:
<mc:MyControl Foreground="White">
And all the controls inside the MyControl control used this Foreground setting. Now that I've created the control just using C# this is not happening anymore.
Someone know why and how to fix this?
Thanks in advance.
EDIT:
This is the XAML:

#SoMoS - I think what you are talking about is a CustomControl, and not a UserControl. If so, did you apply a control template to your inherited control?
You can read about the differences between custom controls to user controls in here-
http://wangmo.wordpress.com/2007/09/28/user-controls-vs-custom-controls/
http://www.wpftutorial.net/CustomVsUserControl.html
If you will apply a control template to your custom control, you could manage its look just as you would with a User Control with XAML.

WPF Telerik Scatter Point colors

I am beginner in WPF telerik technology framework.
I want custom colors to points in telerik scatter point chart. But colors of points are not changing. What should I do? Is there something fundamentally wrong in what I am doing?
Here is c# code
var pallate = ColorPallate();
var PS = new ScatterPointSeries();
var pallaet = new ChartPalette();
PaletteEntryCollection pall = new PaletteEntryCollection();
for (int i = 0; i < data.GetLength(0); i++)
{
ScatterDataPoint point = new ScatterDataPoint();
point.XValue = data[i, XAxisIndex];
point.YValue = data[i, YAaxisIndex];
int value = 0;
if (!float.IsNaN(PredictedResult[i]))
value = System.Convert.ToInt32(PredictedResult[i]);
var filler = new PaletteEntry();
filler.fill(pallate[value]);
pall.Add(filler);
PS.DataPoints.Add(point);
}
pallaet.SeriesEntries.Add(pall);
this.Cross_Plot.Palette = pallaet;
Where ColorPallate() provide custom color palatte as
private Brush[] ColorPallate()
{
var pallate = new Brush[15];
pallate[0] = new SolidColorBrush(Colors.Red);
pallate[1] = new SolidColorBrush(Colors.Orange);
pallate[2] = new SolidColorBrush(Colors.Green);
pallate[3] = new SolidColorBrush(Colors.Pink);
pallate[4] = new SolidColorBrush(Colors.Black);
pallate[5] = new SolidColorBrush(Colors.Brown);
pallate[6] = new SolidColorBrush(Colors.Crimson);
pallate[7] = new SolidColorBrush(Colors.DarkOrange);
pallate[8] = new SolidColorBrush(Colors.ForestGreen);
pallate[9] = new SolidColorBrush(Colors.Indigo);
pallate[10] = new SolidColorBrush(Colors.DarkKhaki);
pallate[11] = new SolidColorBrush(Colors.Purple);
pallate[12] = new SolidColorBrush(Colors.Gold);
pallate[13] = new SolidColorBrush(Colors.RosyBrown);
pallate[14] = new SolidColorBrush(Colors.Gray);
return pallate;
}
Here is XMAL code

</Style>
</telerik:ScatterPointSeries.DefaultVisualStyle>
</telerik:ScatterPointSeries>
</telerik:RadCartesianChart>
<TextBlock Grid.Column="2" HorizontalAlignment="Left" Margin="131,37,0,0" TextWrapping="Wrap" Text="Well points on X Axis" VerticalAlignment="Top" Width="248"/>
<TextBlock Grid.Column="2" HorizontalAlignment="Left" Margin="389,35,0,0" TextWrapping="Wrap" Text="Well points on Y axis" VerticalAlignment="Top" Width="243"/>
I shall be very thankful to you for your efforts
You could use Telerik's PointTemplateSelector. This allows each point to be customized dynamically in code.

ListView Scrolling does not work when Manipulation events wired into ListviewItem - WP8.1

I have wired Manipulation events with the listviewitem to capture left swipe and right swipe. But when I try to scroll down the listview, it does not work! The manipulation events get fired and the listview does not scroll!
This is the listview Datatemplate
<Grid Height="60" Width="380" Margin="0,0,0,1">
<Grid x:Name="ItemGrid" HorizontalAlignment="Left" VerticalAlignment="Center" Width="380" Height="60" Background="Orange" Canvas.ZIndex="2"
ManipulationMode="TranslateX" ManipulationStarted="On_ChannelItem_ManipulationStarted" ManipulationDelta="On_ChannelItem_ManipulationDelta" ManipulationCompleted="OnChannelItemManipulationCompleted">
<TextBlock x:Name="titleTextBlock" Margin="20,0,0,0" Canvas.ZIndex="2" VerticalAlignment="Center" TextAlignment="Left" FontSize="25" >
</TextBlock>
</Grid>
<Grid x:Name="DelGrid" Opacity="0.0" HorizontalAlignment="Right" VerticalAlignment="Center" Height="60" Background="Red" Canvas.ZIndex="-1" Tapped="On_ChannelDelete_Tap" Width="380">
<Button Content="X" FontSize="25" Canvas.ZIndex="-1" VerticalAlignment="Center" HorizontalAlignment="Center" Width="380" BorderThickness="0" />
</Grid>
</Grid>
This is the manipulation events
private void OnChannelItemManipulationCompleted(object sender, ManipulationCompletedRoutedEventArgs e)
{
Grid ChannelGrid = (Grid)sender;
Grid DeleteGrid = (Grid)((Grid)(ChannelGrid.Parent)).Children[1];
double dist = e.Cumulative.Translation.X;
if (dist < -100) // Swipe left
{
Storyboard SwipeLeft = new Storyboard();
DoubleAnimation OpacityAnimation = new DoubleAnimation();
OpacityAnimation.EnableDependentAnimation = true;
OpacityAnimation.From = 0.0;
OpacityAnimation.To = 1.0;
OpacityAnimation.BeginTime = TimeSpan.FromMilliseconds(0);
OpacityAnimation.Duration = new Duration(TimeSpan.FromMilliseconds(1));
Storyboard.SetTarget(OpacityAnimation, DeleteGrid);
Storyboard.SetTargetProperty(OpacityAnimation, "Opacity");
SwipeLeft.Children.Add(OpacityAnimation);
DoubleAnimation WidthAnimation = new DoubleAnimation();
WidthAnimation.EnableDependentAnimation = true;
WidthAnimation.From = 380;
WidthAnimation.To = 0;
WidthAnimation.BeginTime = TimeSpan.FromMilliseconds(30);
WidthAnimation.Duration = new Duration(TimeSpan.FromMilliseconds(100));
Storyboard.SetTarget(WidthAnimation, ChannelGrid);
Storyboard.SetTargetProperty(WidthAnimation, "Width");
SwipeLeft.Children.Add(WidthAnimation);
SwipeLeft.Begin();
}
else if (dist > 100) // Swipe right
{
Storyboard SwipeRight = new Storyboard();
ColorAnimation changeColorAnimation = new ColorAnimation();
changeColorAnimation.EnableDependentAnimation = true;
changeColorAnimation.To = Colors.Green;
changeColorAnimation.Duration = new Duration(TimeSpan.FromMilliseconds(100));
Storyboard.SetTarget(changeColorAnimation, ChannelGrid);
PropertyPath p = new PropertyPath("(ChannelGrid.Background).(SolidColorBrush.Color)");
Storyboard.SetTargetProperty(changeColorAnimation, p.Path);
SwipeRight.Children.Add(changeColorAnimation);
SwipeRight.Begin();
}
}
How do I enable the normal listview scrolling as well as the swipe? Vertical Scrolling is possible when I remove the manipulation events
Update your manipulation mode to include System:
ManipulationMode="TranslateX,System"

Scale child back in WPF

I have a Grid which scaled/zoomed with ScaleTransform by slider. At runtime many UIElements are added to this Grid.
I want to show some tooltips, but not scaled! How should I do that?
For the example: Grid has scaleX and scaleY 2, so I set new ScaleTransform(0.5, 0.5), but didn't help. It seems that the most similar value is 0.740.. Why?
Even Grid's LayoutTransform.Inverse is set to scale values 0.5.
XAML:
<ScrollViewer HorizontalScrollBarVisibility="Auto" VerticalScrollBarVisibility="Auto" Height="Auto" Width="Auto" Name="graphScrollViewer" ScrollChanged="graphScrollViewer_ScrollChanged">
<Grid Margin="0,0,0,0" Name="graphGrid" Width="Auto" Height="Auto" ScrollViewer.IsDeferredScrollingEnabled="True" MouseLeftButtonDown="graphGrid_MouseLeftButtonDown" MouseLeftButtonUp="graphGrid_MouseLeftButtonUp" MouseMove="graphGrid_MouseMove">
<Grid.LayoutTransform>
<ScaleTransform ScaleX="{Binding ElementName=sldZoom, Path=Value}" ScaleY="{Binding ElementName=sldZoom, Path=Value}" />
</Grid.LayoutTransform>
</Grid>
</ScrollViewer>
<Slider Minimum="0.1" Maximum="20" Value="1" x:Name="sldZoom" Panel.ZIndex="10" Orientation="Horizontal" VerticalAlignment="Bottom" HorizontalAlignment="Right" Margin="0,0,20,20" Height="23" Width="100" ValueChanged="sldZoom_ValueChanged"/>
Code-behind:
(method of Rectangle (MouseEnter event) dynamically added to grid)
private void rect_MouseEnter(object sender, MouseEventArgs e)
{
RectToolTip = new TextBlock();
RectToolTip.HorizontalAlignment = HorizontalAlignment.Left;
RectToolTip.VerticalAlignment = VerticalAlignment.Top;
RectToolTip.TextAlignment = TextAlignment.Center;
RectToolTip.Height = this.HeaderTwoHeight + 1;
RectToolTip.Text = " " + (RectsTasks[(sender as Rectangle)]).Info + " ";
RectToolTip.Background = this.ToolTipBackground;
RectToolTip.Foreground = this.ToolTipFontColor;
RectToolTipBorder = new Border();
RectToolTipBorder.Child = RectToolTip;
RectToolTipBorder.BorderThickness = new Thickness(this.ToolTipBorderThickness);
RectToolTipBorder.BorderBrush = this.ToolTipBorderColor;
RectToolTipBorder.Margin = new Thickness(e.GetPosition((graphGrid)).X + 10, e.GetPosition((graphGrid)).Y + 10, 0, 0);
RectToolTipBorder.VerticalAlignment = System.Windows.VerticalAlignment.Top;
RectToolTipBorder.HorizontalAlignment = System.Windows.HorizontalAlignment.Left;
graphGrid.Children.Add(RectToolTipBorder);
RectToolTipBorder.LayoutTransform = RectToolTip.LayoutTransform = new ScaleTransform(????);
Grid.SetZIndex(RectToolTip, 20);
Grid.SetZIndex(RectToolTipBorder, 20);
}
You need to assign the inverse transform to the child element, so that the child will stay intact.
RectToolTipBorder.LayoutTransform = graphGrid.LayoutTransform.Inverse as Transform;

How to place canvas with drawings inside certain column of a ListView control?

How to place canvas with drawings inside certain column of a ListView control ?
I have this:
<DataTemplate>
<Canvas Width="60" Height="20" Background="Red" ClipToBounds="True" >
<ContentPresenter Content="{Binding Path=Graph}" />
</Canvas>
</DataTemplate>
and:
var canvas = new Canvas();
canvas.Children.Add(new Ellipse(){});
var items = new ObservableCollection<LvItem>() { new LvItem(){ Graph = canvas} };
myListView.ItemsSource = items;
but it shows System.Windows.Controls.Canvas as a text, and not the canvas itself with its drawings.
It's working, check example below.
XAML:
<ListView Name="myListView" >
<ListView.View>
<GridView>
<GridViewColumn Width="140" Header="Grap">
<GridViewColumn.CellTemplate>
<DataTemplate>
<Canvas Width="60" Height="50" Background="Red" ClipToBounds="True" >
<ContentPresenter Content="{Binding Path=Graph}" />
</Canvas>
</DataTemplate>
</GridViewColumn.CellTemplate>
</GridViewColumn>
</GridView>
</ListView.View>
</ListView>
LvItem class:
class LvItem
{
public Canvas Graph { get; set; }
}
Code-behind:
var canvas = new Canvas();
canvas.Children.Add(new Ellipse() { Width = 50, Height = 50, Fill = new SolidColorBrush(Colors.Yellow) });
var canvas2 = new Canvas();
canvas2.Children.Add(new Ellipse() { Width = 50, Height = 50, Fill = new SolidColorBrush(Colors.Blue) });
var items = new ObservableCollection<LvItem>() { new LvItem() { Graph = canvas }, new LvItem() { Graph = canvas2 } };
myListView.ItemsSource = items;
Result:

itemBorder.CornerRadius = new CornerRadius(8);
itemBorder.BorderBrush = new SolidColorBrush(Colors.White);
itemBorder.Height = 70;
// Main stack panel
StackPanel mainPanel = new StackPanel();
mainPanel.Orientation = Orientation.Horizontal;
itemBorder.Child = mainPanel;

Border imageBorder = new Border();
imageBorder.Margin = new Thickness(5, 0, 0, 0);
itemBorder.BorderThickness = new Thickness(2);
itemBorder.CornerRadius = new CornerRadius(2);
itemBorder.BorderBrush = new SolidColorBrush(Colors.White);
itemBorder.Background = new SolidColorBrush(Colors.White);
itemBorder.Height = 45;
itemBorder.Width = 45;
mainPanel.Children.Add(imageBorder);
// The item's image
Image image = new Image();
image.Source = new BitmapImage(new Uri("/Crystal%20Cloud;component/Resources/Images/weapons/swords/sword_0.png"));
imageBorder.Child = image;
// The stack panel for the text
StackPanel textPanel = new StackPanel();
textPanel.Margin = new Thickness(10, 0, 0, 0);
mainPanel.Children.Add(textPanel);
// The title text block
TextBlock titleText = new TextBlock();
titleText.Text = "Wooden Dagger";
titleText.FontFamily = new FontFamily("Comic Sans MS");
textPanel.Children.Add(titleText);
// The status text block
TextBlock statusText = new TextBlock();
statusText.Text = "DPS: 1";
statusText.FontFamily = new FontFamily("Comic Sans MS");
statusText.FontSize = 16;
statusText.Margin = new Thickness(15, 0, 0, 0);
textPanel.Children.Add(statusText);
return itemBorder;
}
Erg... just found the bug itemBorder should be changed to imageBorder.
