非常感谢！] 1

Answer 1

If dgv.IsCurrentCellInEditMode = True Then
    MsgBox("Please exit edit mode and try again.")
    Exit Sub
End If
Execute("DELETE FROM tblSample;")

Dim c As Integer = 0
Dim dgv As Integer = dgv.Rows.Count - 1
While c < dgv
    Execute("INSERT INTO tblSample VALUES (" + dgv.Item(0, c).Value.ToString + "," + dgv.Item(x, c).Value.ToString + ");")
    c += 1
End While
fillDatatable(xDT, "SELECT * FROM tblSample;")
dgv.DataSource = xDT
dgv.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.Fill
dgv.Refresh()
MsgBox("Changes Applied!")



Public Sub fillDatatable(_datatable As DataTable, Query As String)
    Dim sqlQuery As String = (Query)
    Using conn As New SqlConnection(yourConnectionString)
        conn.Open()
        Using da As New SqlDataAdapter(sqlQuery, conn)
            da.Fill(_datatable)
        End Using
        conn.Close()
    End Using
End Sub

这假设你有一个＆＃34;执行＆＃34;执行SQL查询的方法。（tblSample =你的桌子）（dgv =您的datagrdview）（x =行号（0,1,2,3 ...））它使用数据表作为临时＆＃34;保存点＆＃34;对于数据，不是最有效的，但它应该工作。希望它有所帮助！的xD
