“功能区组合框"并不总是选择您单击的项目. [英] Ribbon Combo Box not always selecting the item you click on.

问题描述

你好

我正在使用WPF的功能区控件(版本4.0)，偶尔遇到一个问题，当尝试从功能区组合框中选择一个项目时，该项目没有被选择并且该字段留为空白.以下是SelectionChanged之一的示例 我实现的事件处理程序，该事件处理程序附加到出现此问题的组合框之一.

I am using the Ribbon Control for WPF (Version 4.0), and am having an issue where occasionally, when attempting to select an item from a Ribbon Combo Box, the item is not selected and the field is left blank. The following is an example of one of the SelectionChanged event handlers that I have implemented which is attached to one of the Combo Boxes that are having this issue.

 

 private void VersionListGallery_SelectionChanged(object sender, RoutedPropertyChangedEventArgs<object> e)
 {
  if (this.VersionListGallery.SelectedItem == null)
  {
  return;
  }
  this.VersionId = (Identifier)this.VersionListGallery.SelectedItem;
 }

推荐答案

Hello Josh，

Hello Josh,

如何在Ribbon中定义ComboBox控件，我们必须将ComboBox放入RibbonGallary.请参考该主题.

How do you define your ComboBox controls in Ribbon, we must put the ComboBox into RibbonGallary. Please refer to this thread.
