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

你想在这里实现什么？只是动态添加列？ 虽然您可以使用这些代码动态添加列和行 what do you want to achieve in this ? just to add columns dynamically? though you can use these code to add columns and rows dynamically 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
