How WPF changes animation trigger rig values behind the scenes

EventTrigger's actions are not actions, and actions can support multiple actions

The togglebutton beginstoryboard in the loaded event and then pause immediately.

beginstoryboard ..Just want to get a name.

pausestoryboard ..

resumestoryboard ..

routedevent="Time out.

pausestoryboard...

In addition, ToggleButton supports 3 states (set via isthreestate): checked unchecked indeterminate

The value of the ischecked property is true false null, and the property type is bool?

So there's one more event:

The easiest way to do this is to use ToggleButton instead and write two triggers, one for Event and one for UnChecked

You can try using the mediaelement control to ***** the file, you draw a mediaelement on the interface, put it at the bottom of the screen, set the opacity to 0, and then set the name property to mediaelement1

Write { in the checked event of the togglebutton; unchecked event; In this way, when checked** unchecked, pause, and click again to continue**.

Yes, for example, when the control height changes to 200, set the background color to red.

property="height" value="200"/>

Yes, any widget has a sizechanged event. You go to the background and go to the animation you want to start! ~

Define a template yourself, and then start a similar sample when you set sizechanged in the trigger.

Your idea of doing this is not in line with WPF's thinking, the business logic and the interface are separated, and you should use the viewmodel to do it.

Generally similar to the control name, value).

I have a question and would like to consult the landlord. The bound path is used to set the "properties" of the bound object. For example, when a textbox is used to display the studentname of the student class in the background, it will be written as What I don't understand is path=desiredsize height What is this?

How can a property name participate in a calculation operation?

I'm sorry to dig a grave, leave a solution for those who are looking for the same problem in the future, you use int32animation, the interpolation is integer, if you want to animate continuous, you should use doubleanimation, so that the interpolation is not a discrete integer point.

You can use binding:

Among them, the abc in converter=abc is the converter you need top+10

It's better to write in the background, you can get the property by writing in the foreground, to=""To +10 on the original basis, I think of a way to use converter...

WPF, like Silverlight, provides a foreground display conversion mechanism called a converter when data binding.

For example, if you display an int value in a textblock, the value of "0" will be green; Less than 0 is shown in red.

Then you create a converter class to do the data conversion process (there are many examples and tutorials on the Internet).

That's how the front desk works:

This way, the font color of the textblock will change as the content changes. The same can be applied to the listview control.

Background writing is usually very complicated, try to write it as resource in XAML, and it can be used in the background"key"] as style

key"] as style

A similar approach applies.
