RibbonGallery选中的项目被卡住了

本文介绍了RibbonGallery选中的项目被卡住了的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

嗨！ $ 在RibbonSplitButton中我有一个 RibbonGallery ，它有一个可观察集合的ItemsSource。 当点击下拉列表列表中的任何项目时，它会触发一个窗口显示。 问题是，当我关闭窗口时，打开再次下拉，之前选择的项目一直被选中，使我无法通过点击它触发窗口外观。 如果我更新observablecollection，下拉列表会更新，并且删除选择，但效率非常低。

如何删除选择以不同的方式？ 提前致谢！

解决方案

您好 oolin， 您可以尝试以下方法。 您可以添加IsSelected属性在您的模型中将绑定到RibbonGallery。

private string _label; public bool IsSelected { get { return _isSelected; } 设置 { if（_isSelected！= value） { _isSelected = value; OnPropertyChanged（new PropertyChangedEventArgs（" IsSelected"））; } } }

并在RibbonGallery.GalleryItemStyle中绑定IsSelected属性。

< ribbon：RibbonGallery.GalleryItemStyle> < Style TargetType =" ribbon：RibbonGalleryItem"> //< Setter Property =" IsSelected"值=" {Binding IsSelected}" /> < Setter Property =" IsSelected" Value =" {Binding IsSelected，Converter =}" /> < / Style> < / ribbon：RibbonGallery.GalleryItemStyle>

最后，使用转换器设置Property =" IsSelected"假（总是）。然后，之前选择的项目将不会被选中。 您可以参考样本： 如何添加图库到我的功能区 $ 此外，你可以使用 RibbonButton 下划线以触发显示的窗口。 最好的问候， Yong Lu

Hi! Inside a RibbonSplitButton I have a RibbonGallery, which has an ItemsSource of an observablecollection. When any item on the dropdown list is clicked, it triggers a window to be displayed. The problem is, when I close the window, and open the dropdown again, the previously selected item keeps being selected, making it unable for me to trigger the windows appearence by clicking on it. If I update the observablecollection, the dropdown is updated, and the selection is removed, but its pretty inefficient.

Any ideas how to remove the selection in a different fashion? Thanks in advance!

解决方案

Hi oolin, You may can try the following method. You can add a IsSelected property in your model which will bind to the RibbonGallery.

private string _label; public bool IsSelected { get { return _isSelected; } set { if (_isSelected != value) { _isSelected = value; OnPropertyChanged(new PropertyChangedEventArgs("IsSelected")); } } }

And binding the IsSelected property in your RibbonGallery.GalleryItemStyle.

<ribbon:RibbonGallery.GalleryItemStyle> <Style TargetType="ribbon:RibbonGalleryItem"> //<Setter Property="IsSelected" Value="{Binding IsSelected}" /> <Setter Property="IsSelected" Value="{Binding IsSelected,Converter=}" /> </Style> </ribbon:RibbonGallery.GalleryItemStyle>

Finally, use a Converter set the Property="IsSelected" to false(always). Then, the previously selected item will not keep being selected. You can refer the sample:How do I add Galleries to my Ribbon Besides, You can use the RibbonButton to trigger a window to be displayed. Best Regards, Yong Lu
