我的尝试：



'DataGridView1.Rows.Add（）



'Dim cmb As New DataGridViewComboBoxColumn（）

'Dim cmb1 As New DataGridViewComboBoxColumn（）

'Dim cmb2 As New DataGridViewComboBoxColumn（）

'Dim txtbox As New DataGridViewTextBoxColumn（）

'Dim cmbOthers As新的DataGridViewComboBoxColumn（）



'对于i = 0到3



'cmb.HeaderText =选择数据

'cmb.Name =cmb

'cmb.MaxDropDownItems = 4

'cmb.Items.Add（1 / 3）

'cmb.Items.Add（1/2）

'DataGridView1.Columns.Add（cmb）



'cmb1.HeaderText =选择数据1

'cmb1.Name =cmb1

'cmb1.MaxDropDownItems = 4

'c mb1.Items.Add（True）

'cmb1.Items.Add（False）

'DataGridView1.Columns.Add（cmb1）

What I have tried:

'DataGridView1.Rows.Add()

'Dim cmb As New DataGridViewComboBoxColumn()
'Dim cmb1 As New DataGridViewComboBoxColumn()
'Dim cmb2 As New DataGridViewComboBoxColumn()
'Dim txtbox As New DataGridViewTextBoxColumn()
'Dim cmbOthers As New DataGridViewComboBoxColumn()

' For i = 0 To 3

'cmb.HeaderText = "Select Data"
'cmb.Name = "cmb"
'cmb.MaxDropDownItems = 4
'cmb.Items.Add("1/3")
'cmb.Items.Add("1/2")
'DataGridView1.Columns.Add(cmb)

'cmb1.HeaderText = "Select Data1"
'cmb1.Name = "cmb1"
'cmb1.MaxDropDownItems = 4
'cmb1.Items.Add("True")
'cmb1.Items.Add("False")
'DataGridView1.Columns.Add(cmb1)

推荐答案

Dim cmb(2) As DataGridViewComboBoxColumn
Dim txt As New DataGridViewTextBoxColumn


With DataGridView1
    For i As Int16 = 0 To 2
        cmb(i) = New DataGridViewComboBoxColumn
        cmb(i).HeaderText = "Data" & i
        .Columns.Add(cmb(i))

    Next
    .Columns.Add(txt)
    For i As Int16 = 0 To 3
        .Rows.Add()
    Next
End With
