Question

我有一个文本框。按Enter键时，我希望它将DatagridView选中的行更改为下一行。

到目前为止我所拥有的内容无效。

private void textBox_KeyPress(object sender, KeyPressEventArgs e)
{
    if (e.KeyChar == (int)Keys.Enter)
    {
        save_Click(sender, e);
        asd(sender, e);
    }
}


private void asd(object sender, KeyPressEventArgs e)
{
    SendKeys.Send("{Tab}"); //also tried enter
}

您应该按如下方式编写代码，以便在文本框的按键事件中重复行！

private void textBox1_KeyDown(object sender, KeyEventArgs e)
    {
        if (e.KeyCode == Keys.Enter)
        {
            int CurrentRow = dataGridView1.CurrentCell.RowIndex;
            CurrentRow++;
            if (CurrentRow < dataGridView1.Rows.Count)
            {
                dataGridView1.CurrentCell = dataGridView1.Rows[CurrentRow].Cells[0];
            }
            else
            {
                dataGridView1.CurrentCell = dataGridView1.Rows[0].Cells[0];
            }
        }
    }

捕获回车键最好覆盖ProcessCmdKey。

protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
{
    if (keyData == Keys.Enter)
    {
        if (yourTextBox.Focused)  // only when your are in the TextBox
        {
           advanceRow(yourDataGridView);
           return false;          // probably don't add new line
        }
    }
    return base.ProcessCmdKey(ref msg, keyData);
}

为了推进当前行，最好使用一个函数..

int advanceRow(DataGridView dgv)
{
    int current = dgv.CurrentRow.Index;
    if (current < dgv.Rows.Count - 1)  // only if we hae not reached the bottom
    {
        dgv.CurrentCell = dgv[ 0, current + 1];
        return current + 1;
    }
    return current;
}

TextBox按键（输入）增加datagridview选定的行
