没有在UserControl WPF中设置焦点 [英] Focus is not set in UserControl WPF

问题描述

我无法将重点放在用户控制项上
我在用户控件中使用DataGrid
我想把重点放在DataGrid的第一行

我发现以下代码

I cannot able to set focus on User Control Item
I am using DataGrid in User Control
I want to set focus on First row of DataGrid

I found following code

int index = 0;
     dgAccountInfo.SelectedItem = winAccountInfoGrid.dgAccountInfo.Items[index];
                    dgAccountInfo.ScrollIntoView(winAccountInfoGrid.dgAccountInfo.Items[index]);
                    DataGridRow dgrow = (DataGridRow)dgAccountInfo.ItemContainerGenerator.ContainerFromIndex(index);
      if (dgrow != null)
               dgAccountInfo.MoveFocus(new TraversalRequest(FocusNavigationDirection.Next));

通过运行以上代码，我发现 ContainerFromIndex 方法始终返回null


为了解决空问题，我发现了以下链接

By running above code I found ContainerFromIndex method always returns null


To rid of null problem I found following link

I come out of null problem using above link but still focus is not set on data grid

Thanks for reading my question

推荐答案

似乎您也需要给予控件焦点.这是在WPF中设置焦点 [ ^ ].

It seems that you will need to give the control focus as well. here is a link to a blog post on setting focus in WPF[^].
