VB中datagrid如何添加

界面里点击datagrid控件，

法一：如果已经连接数据源、表、有查询语句，单击右键，选择“字段刷新”（retrieve fields），确定。

法二：单击右键，选择“编辑”（edit）编辑该控件，通过编辑控件（此时再次单击右键，插入行或列）完成

vb.net Datagridview添加行，需要四个按钮，一个datagridview控件。代码如下：

Public Class Form1

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

'添加行

Me.DataGridView1.Rows.Add()

End Sub

Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click

'添加列

Me.DataGridView1.Columns.Add("1", "on")

End Sub

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click

'删除行

Me.DataGridView1.Rows.RemoveAt(0)

End Sub

Private Sub Button4_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button4.Click

'删除列

Me.DataGridView1.Columns.RemoveAt(0)

End Sub

End Class
