在WPF按钮显示点 - 点 - 点进步 [英] Display dot-dot-dot progress in a WPF button

问题描述

我发现用来表示在进度条和轮然而使用进度相当多的例子;我能找到的只有一个JavaScript的例子来说明一个省略号（点 - 点 - 点）指的进步，因此我觉得问这个问题的。我的应用程序是不是很复杂 - 它只有几个检查框和一个按钮。最近我的团队要求提供的增强，并希望保持它很简单。

I found quite a few examples for showing progress where the progress bars and wheels are used however; I could find only one javascript example to show an ellipsis (dot-dot-dot) to refer progress hence I thought of asking this question. My app is not very complex - it only has a few check-boxes and one button. Recently my team requested for an enhancement and want to keep it simple as well.

有一个名为GO用户配置所需的设置后，点击按钮。其背后的code也确实简单 - 它的单击事件后关闭按钮，呼叫是使用一个独立的EXE 的ProcessStartInfo 执行三项行动reconcle，岗位和发布。我用的是 WaitForExist（）的方法来重新启用按钮。

There is a button named 'GO' that the user clicks after configuring the required settings. The code behind it is also really straightforward - it disables the button after the click event and call's a standalone exe using ProcessStartInfo that performs three actions 'reconcle', 'post' and 'publish'. I use the WaitForExist() method to re-enable the button.

我的要求我的团队，以显示在按钮上的当前进程。他们只是想在按钮上的文字显示调和。核对..核对...（定期说，1秒），随后以类似的方式发布和出版

I was requested by my team to show the 'current process' on the button. They simply want the button text to show Reconciling. Reconciling.. Reconciling... (at regular intervals say, 1 sec) followed by Posting and Publishing in a similar fashion.

这将是很好知道最合适的方式来实现这一目标。先谢谢了。

It would be nice to know the most appropriate way to achieve this. Thanks in advance.

推荐答案

这样做的最简单的方法是使用 ObjectAnimationUsingKeyFrames 。设置TargetProperty上的内容，并设置每个 DiscreteObjectKeyFrame 的值到调和。调和调和... ... 。

The simplest way of doing that is using an ObjectAnimationUsingKeyFrames. Set the TargetProperty on the Content and set the Value of each DiscreteObjectKeyFrame to Reconciling. Reconciling.. Reconciling....

例如用于控件模板与内容presenter 名为 PART_Content ：

<ControlTemplate.Triggers>
    <Trigger Property="IsEnabled" Value="False">
        <Trigger.EnterActions>
            <BeginStoryboard>
                <Storyboard>
                    <ObjectAnimationUsingKeyFrames Storyboard.TargetName="PART_Content" Storyboard.TargetProperty="Content" Duration="00:00:00.8" RepeatBehavior="Forever">
                        <DiscreteObjectKeyFrame KeyTime="00:00:00.0" Value="Loading"/>
                        <DiscreteObjectKeyFrame KeyTime="00:00:00.2" Value="Loading."/>
                        <DiscreteObjectKeyFrame KeyTime="00:00:00.4" Value="Loading.."/>
                        <DiscreteObjectKeyFrame KeyTime="00:00:00.6" Value="Loading..."/>
                    </ObjectAnimationUsingKeyFrames>
                </Storyboard>
            </BeginStoryboard>
        </Trigger.EnterActions>
    </Trigger>
</ControlTemplate.Triggers>
