如何设置DataGridViewTextBoxColumn的密码属性

本文关键字：DataGridViewTextBoxColumn 密码属性设置何设置 | 更新日期: 2023-09-27 18:05:59

我使用DataGridView实现用户名-密码UI。密码在"DataGridViewTextBoxColumn类型"列中显示。我如何使用现有的代码DataGridViewTextBoxColumn和实现密码属性的文本?

处理EditingControlShowing事件，然后将编辑控件转换为TextBox并手动将UseSystemPasswordChar设置为true:

TextBox passwordText = e.Control as TextBox;
if (passwordText != null)
{
    passwordText.UseSystemPasswordChar = true;
}

<标题>编辑

你可以试试这个吗:

private void dataGridView1_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)
{
    if (dataGridView1.Columns[e.ColumnIndex].Name == “passwordDataGridViewTextBoxColumn” && e.Value != null)
    {
        dataGridView1.Rows[e.RowIndex].Tag = e.Value;
        e.Value = new String(‘*’, e.Value.ToString().Length);
    }
}
private void dataGridView1_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
{
    if (dataGridView1.CurrentRow.Tag != null)
        e.Control.Text = dataGridView1.CurrentRow.Tag.ToString();
}

if (e.ColumnIndex >= 0)
{
    if (dataGridView.Columns[e.ColumnIndex].Name == "Password" && e.Value != null)
    {
        dataGridView.Rows[e.RowIndex].Tag = e.Value;
        e.Value = new String(''u2022', e.Value.ToString().Length);
    }
}
