如何将焦点设置到 WPF 工具包数据网格的特定单元格 [英] how to set focus to particular cell of WPF toolkit datagrid

问题描述

我正在使用 WPF 工具包提供的 DataGrid 控件来显示产品列表及其 OpenStock、描述等.在此 DataGrid 中，我已将 OpenStock 列设置为可编辑，其余列不可编辑.我现在想要什么，当我的这个窗口加载时，我想将键盘焦点设置到 OpenStock 列的第一个单元格，如果可能的话，在编辑模式下.我搜索了 2 天，最后在这里发帖.

I am using WPF toolkit provided DataGrid control to display product list along with its OpenStock, Description etc. In this DataGrid i have set OpenStock column to editable and rest are non-editable. What i want now when my this windows loads, I want to set keyboard focus to first cell of OpenStock column and if possible in edit mode. I searched this for 2 days and finally posting here.

推荐答案

您需要将当前单元格设置为要编辑的单元格，然后调用 BeginEdit 在你的 Loaded 处理程序中:

You need to set the current cell to the one you want edited and then call BeginEdit in your Loaded handler:

dataGrid1.CurrentCell = new DataGridCellInfo(
    dataGrid1.Items[0], dataGrid1.Columns[3]);
dataGrid1.BeginEdit();

如果您在 XAML 中为您的 DataGridTextColumn 命名，您可以使用该名称而不是 Columns[3].

If you give your DataGridTextColumn a name in XAML you can use that name rather than Columns[3].
