将checkboxcolumn添加到DataGridView中

我使用VS 2008和VB.NET作为语言。我有两个网格。在一个网格中,ii具有用户的数据。例如手机号码,电子邮件和其他信息。在第二个网格中,我已经添加了一些警报。

我需要在警报gridview中的每一行附加两个复选框列。单击该复选框,将执行特定的数据库操作。

目前,我在datagridview中添加了复选框,但我无法检查/取消选中它们。

请帮我解决检查/取消选中问题,并提示我执行复选框点击的数据库操作。

这就是我在datagridview

中添加复选框的方法
Dim email As DataGridViewCheckBoxColumn = New DataGridViewCheckBoxColumn(True)
Dim sms As DataGridViewCheckBoxColumn = New DataGridViewCheckBoxColumn(True)

email.HeaderText = "Email"
email.ReadOnly = False
sms.HeaderText = "SMS"
sms.ReadOnly = False

UserAlarmDataGridView.Columns.Add(email)

UserAlarmDataGridView.Columns.Add(sms)

我尝试将列的readonly属性设置为false,但它不起作用。

检查以下代码

Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
    Dim AlarmColumn1 As New DataGridViewCheckBoxColumn(True)
    Dim AlarmColumn2 As New DataGridViewCheckBoxColumn(True)

    AlarmColumn1.Name = "Alarm1"
    AlarmColumn1.HeaderText = "Email"
    AlarmColumn1.ReadOnly = False

    AlarmColumn2.Name = "Alarm2"
    AlarmColumn2.HeaderText = "SMS"
    AlarmColumn2.ReadOnly = False

    UserAlarmDataGridView.Columns.Add(AlarmColumn1)
    UserAlarmDataGridView.Columns.Add(AlarmColumn2)
    UserAlarmDataGridView.ReadOnly = False
End Sub

基于CheckBox单击进行数据库操作,请使用以下

Private Sub UserAlarmDataGridView_CellContentClick(sender As Object, _
    e As System.Windows.Forms.DataGridViewCellEventArgs) Handles UserAlarmDataGridView.CellContentClick

    Dim ColumnName1 As String = UserAlarmDataGridView.Columns(e.ColumnIndex).Name

    If ColumnName1 = "Alarm1" Or ColumnName1 = "Alarm2" Then
        Dim CellCheckBox1 As DataGridViewCheckBoxCell = _
            CType(UserAlarmDataGridView.Rows(e.RowIndex).Cells(ColumnName1), DataGridViewCheckBoxCell)

        Dim CellCheckBoxState1 As String = CellCheckBox1.EditingCellFormattedValue.ToString

        MsgBox("Row = " & CellCheckBox1.RowIndex & vbCrLf & _
               "Column = " & CellCheckBox1.ColumnIndex & vbCrLf & _
               "State = " & CellCheckBoxState1)
    End If
End Sub

捕获复选框状态值的更好方法....

micInputStream.on('data', function(data) {
    console.log("Recieved Input Stream: " + data.length);
});
