重写C1FlexGrid的按键事件

PreviewKeyDown="flex_PreviewKeyUp"  

定义按键方法

 private void flex_PreviewKeyUp(object sender, KeyEventArgs e)
{
if (e.Key == Key.Enter)
{
// 获取当前编辑的单元格
var cell = CfgReviewItem.Selection;
if (cell.Column >= 0 && cell.Row >= 0)
{
// 获取当前单元格的编辑器（C1MaskedTextBox）
var editor = e.OriginalSource as C1MaskedTextBox;
if (editor != null)
{
// 插入换行符
int caretIndex = editor.CaretIndex;
editor.Text = editor.Text.Insert(caretIndex, Environment.NewLine);
editor.CaretIndex = caretIndex + Environment.NewLine.Length;
}
}
e.Handled = true;
}
}
