我有一个DataGridView和一个文本框。我想显示datagridview单元格值(在编辑模式下)到Excel等文本框。 我正在尝试这样的事情:

private void dataGridView1_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
    {
        var ctl = e.Control as DataGridViewTextBoxEditingControl;
        if (ctl == null)
        {
            return;
        }
        ctl.KeyPress -= ctl_Keypress;
        ctl.KeyPress += new KeyPressEventHandler(ctl_Keypress);
    }

和:

private void ctl_Keypress(object sender, KeyPressEventArgs e)
    {
        var box = sender as System.Windows.Forms.TextBox;
        if (box == null)
        {                
            return;
        }
        tb_currendCellValue.Text = box.Text;            
    }

,但目前无法正常工作。 请帮我。谢谢。

解决:将“ KeyPress”更改为keyUp才能正常工作。

我相信这是您的问题的答案:Change datagridview cell value in edit mode

我将上面的链接中的想法重新编码为您的案例,并对其进行了测试。我在编辑控件中创建了_KeyUp事件。如果编辑控件是TextBox类型,则应添加更多内容,例如测试。

enter image description here

C#

private TextBox CtrlTextbox;
private void DataGridView2_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
{
    if (RowIdx >= 0)
    {
        CtrlTextbox = (TextBox)e.Control;
        CtrlTextbox.KeyUp += CopyText;
    }
}

private void CopyText(object sender, KeyEventArgs e)
{
    this.TextBox1.Text = sender.Text;
}

VB.NET

Dim CtrlTextbox As TextBox
Private Sub DataGridView2_EditingControlShowing(sender As Object, e As DataGridViewEditingControlShowingEventArgs) Handles DataGridView2.EditingControlShowing
    If RowIdx >= 0 Then
        CtrlTextbox = CType(e.Control, TextBox)
        AddHandler CtrlTextbox.KeyUp, AddressOf CopyText
    End If
End Sub

Private Sub CopyText(sender As Object, e As KeyEventArgs)
    Me.TextBox1.Text = sender.Text
End Sub

哦,还有另一种好的方法-绑定。请参阅这篇文章:A Detailed Data Binding Tutorial 如果您看一章,数据绑定还有什么用?,您会确切地看到您的情况。
