SHAREDSIZEGROUP
You can use the SharedSizeGroup attribute to share column sizes across different grids. You can’t normally share sizes of star-sized columns across multiple grids, however, since star sizing works only in the context of the current grid.. Below is an example of how to get a star sized column to be the same size as a star sized column in adifferent grid.
DESIREDSIZE
After the measure phase, during which a custom element calls the Measure method on each of its child elements, each child element will set its DesiredSize property to indicate how much space it wants. The DesiredSize of a child element accounts for any margins that have been set on that child. Assume that we have the following XAML (MyElement is a custom element with a single child). ZINDEX | 2,000 THINGS YOU SHOULD KNOW ABOUT WPF You can set the Canvas.ZIndex attached property for a child element of the Canvas panel, to dictate the overlap behavior of child elements. Elements with a higher ZIndex value will appear on top of elements with a lower value.. By default, all child elements of a Canvas have a ZIndex value of 0. In this case, the Canvas lays out the child elements in the order that they exist in the ChildrenCANCONTENTSCROLL
By default, the ListBox control scrolls intelligently, one item at a time. Scrolling behavior in a ListBox is provided by a ScrollViewer.. By default, the CanContentScroll property of the containing ScrollViewer is set to true, indicating that the items panel (e.g. a StackPanel) is responsible for the scrolling. The StackPanel scrolls one item at a time as you drag the scrollbar thumb.

FontStyle – Set font as italic (e.g. Italic, Oblique) FontWeight – Set font as bold or light (e.g. Bold, Light, Extra-Bold, etc) Below is a simple example. 1. ROTATION | 2,000 THINGS YOU SHOULD KNOW ABOUT WPF You can apply a rotation transform to a 2D point using a 2 x 2 transformation, multiplying it by a 2 x 1 point matrix. This results in a second 2 x 1 point matrix that represents the transformed (rotated) point. In WPF, however, rotation transforms are done using homogeneous coordinates, which means that we multiply a 3 x 3 transformation matrix by a 3 x 1 point matrix.ISHITTESTVISIBLE

In WPF, the preferred method for executing some code when a button is clicked is to use a command . A command is an object that represents an action to be taken and is bound to a particular method that performs the action. The button is then associated with the command by setting its Command property. Here’san example.

#885 – WRAPPING A GRID IN A SCROLLVIEWER August 15, 2013 2 Comments. Because the ScrollViewer control is a ContentControl, it can contain any single element. It most often contains a single Panel, which in turn contains child elements. Below is an example of a ScrollViewer that contains a Grid, which in #556 – CLIPPING TO A BORDER USING AN OPACITY MASK When you specify a border radius for a Border element, the content within the Border is not automatically clipped to the new rounded interior.

FontStyle – Set font as italic (e.g. Italic, Oblique) FontWeight – Set font as bold or light (e.g. Bold, Light, Extra-Bold, etc) Below is a simple example. 1. #778 – ANIMATING A SCALE TRANSFORM Here’s another example of an animation of a 2D transform. In this case, we animate the scale of the object so that it grows larger and smaller and then repeats the behavior. This results in a sort of pulsating button.

Posts about IsHitTestVisible written by Sean. If you set the IsHitTestVisible property of a container element to false, it will turn off hit testing for all elements within that container. Even if a child element sets its own IsHitTestVisible property to true, it will still be hidden from hit testing. The false value set at the container level applies to all child elements, no matter what #989 – ENABLING LIVE FILTERING IN A COLLECTIONVIEWSOURCE Like sorting, filtering in a CollectionViewSource is not automatically done when you change the contents of one of the data bound items. By default, you need to call the Refresh method of the CollectionViewSource. In the example below, we filter on first name "Joan" and then change Joan Fontaine's first name to "Bob". Noticethat the list is
2,000 THINGS YOU SHOULD KNOW ABOUT WPF You can define a custom data template for items in a TreeView, displaying any content you like in a panel, for each data item.. There’s a problem with doing this, however, if you want the container in the data template to stretch the entire width of the TreeView.In the sample below, we have a data template for a dog breed the displays data across three columns in a Grid.SHAREDSIZEGROUP
You can use the SharedSizeGroup attribute to share column sizes across different grids. You can’t normally share sizes of star-sized columns across multiple grids, however, since star sizing works only in the context of the current grid.. Below is an example of how to get a star sized column to be the same size as a star sized column in adifferent grid.
2,000 THINGS YOU SHOULD KNOW ABOUT C# In C# 6.0, you can use a using directive not only with namespace names, but also with the name of a static class. This allows invoking static methods in the class without having to specify the class name. For example, assume that we have a static class Utility with an AddInts method. Assume also that Utility is defined within a namespace having the name SomeNamespace.DESIREDSIZE
After the measure phase, during which a custom element calls the Measure method on each of its child elements, each child element will set its DesiredSize property to indicate how much space it wants. The DesiredSize of a child element accounts for any margins that have been set on that child. Assume that we have the following XAML (MyElement is a custom element with a single child). ZINDEX | 2,000 THINGS YOU SHOULD KNOW ABOUT WPF You can set the Canvas.ZIndex attached property for a child element of the Canvas panel, to dictate the overlap behavior of child elements. Elements with a higher ZIndex value will appear on top of elements with a lower value. By default, all child elements of a Canvas have a ZIndex value of 0. In this case, the Canvas lays out the childCANCONTENTSCROLL
By default, the ListBox control scrolls intelligently, one item at a time. Scrolling behavior in a ListBox is provided by a ScrollViewer.. By default, the CanContentScroll property of the containing ScrollViewer is set to true, indicating that the items panel (e.g. a StackPanel) is responsible for the scrolling. The StackPanel scrolls one item at a time as you drag the scrollbar thumb. VERTICALCONTENTALIGNMENT Recall that the HorizontalAlignment and VerticalAlignment properties specify how child controls should be located and sized within their parent container.. The HorizontalContentAlignment and VerticalContentAlignment properties are similar, but specify how a control’s content should be aligned, within the interior of the control.. Below is an example of some non-default values for CANEXECUTE | 2,000 THINGS YOU SHOULD KNOW ABOUT WPF July 14, 2011 3 Comments. In WPF, the preferred method for executing some code when a button is clicked is to use a command . A command is an object that represents an action to be taken and is bound to a particular method that performs the action. The button is then associated with the command by setting its Command property. Here’san example.
SCALETRANSFORM
A 2D scale transform in WPF is accomplished by using a transformation matrix. The transformation matrix is multiplied by another matrix representing a single 2D point to be transformed. The resulting matrix describes the transformed point. When scaling a user interface element, this transformation is done individually on each point togenerate

BASICS | 2,000 THINGS YOU SHOULD KNOW ABOUT WPF To convert from DIPs to pixels, you need to know your screen DPI setting (e.g. 96, 120): # pixels = (DIPs) * (DPI / 96) So 96 DIPs = 96 pixels at 96 DPI, and 96 DIPs = 120 pixels at 120 DPI.

Because ToggleButton is a ContentControl, it can contain a single child element that can be any .NET object. You typically set the ToggleButton’s content to a text string, which appears as a label on the button. But you can also set the content to some other control. In the example below, the content of each ToggleButton in a panel is set to an Image control.

ABOUT 2,000 THINGS
The idea behind the 2000things.com project is to present a series of lists of things that you should know about a particular technology, which each post building on previous posts and adding a small amountof information.
Here are the 2,000 Things blogs that I publish: 2,000 Things You Should Know About C# – A list of things about the .NET programming language C# 2,000 Things You Should Know About WPF – A list of things about the WPF programming environment 2,000 Things You Should Know About HTML – A list about creating web content using HTML As of early 2019, both of these blogs contain a bit over 1,200 posts, but both are dormant at the moment–I’m not adding more content. The third blog is brand new, so doesn’t yet contain any content.Stay tuned!
