RibbonComboBox 选定的图库项目在鼠标离开时恢复为旧值 [英] RibbonComboBox selected gallery item reverts to old value on mouse leave

问题描述

我已将 WPF 功能区替换为最新的库，组合框选择更改会触发数据网格的重新加载.我对 RibbonComboBox 有问题.

i have replaced WPF ribbons to the newest library, the combobox selection changed triggers reload of datagrid. I have problem with the RibbonComboBox.

如果我用鼠标光标离开所选项目，则所选项目将恢复为旧项目.如果我将光标保持在所选项目上，直到数据网格重新加载完成，则新值会被 Ribboncombobox 接受.

If i leave with mousecursor out of the selected item, the selected item is reverted to the old item. if i keep cursor on the selected item until the datagrid reload is finished, the new value is accepted to the ribboncombobox.

我是否错过了一些特殊的ribboncombobox 属性以仅通过单击接受更改，或者这是组合框组件中的错误?唯一可能的解决方法是在线程中启动数据网格重新加载功能，让功能区组合框完成其进程.

Do i miss some special ribboncombobox property to accept change by click only or this is a bug in the combobox component? only possible workaround would be launch datagrid reload function in thread to let the ribbon combobox finish its processes.

此处的示例代码:

<r:RibbonComboBox>
       <r:RibbonGallery SelectedValuePath="Content" SelectionChanged="pgSize_SelectionChanged">
         <r:RibbonGalleryCategory>
            <r:RibbonGalleryItem Tag="20" Content="Size (20)" Foreground="Green" />
            <r:RibbonGalleryItem Tag="30" Content="Size (30)" Foreground="Green" IsSelected="True"/>
            <r:RibbonGalleryItem Tag="50" Content="Size (50)" Foreground="Orange" />
            <r:RibbonGalleryItem Tag="100" Content="Size (100)" Foreground="Red" />
         </r:RibbonGalleryCategory>
       </r:RibbonGallery>
</r:RibbonComboBox>      

推荐答案

这是功能区控件中的错误.请参阅连接错误报告.

This is a bug in the ribbon control. See the Connect bug report.
