如何为DataGridViewTextBoxColumn设置Password属性

我已经使用DataGridView来实现用户名密码UI。 密码显示在DataGridViewTextBoxColumn类型列中。 如何使用DataGridViewTextBoxColumn的现有代码并实现文本的密码属性？

Answer 1

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; }

你能试一试吗：

 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(); } 

Answer 2

 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); } }
