很多初学VB.NET的新手，差不多都是对许多小功能不能实现而苦恼，
以下我个人在论坛中遇到的许多问题的综合的通用代码，供初学者研究学习：

    '通用样式化Datagird
    'Power by:landlordh
    '调用:
    '  strHeaders() 里面改为自已需要的列名
    '  iWidths()    里面改为相对应的列宽
    '  inputnum     在样式化之前赋值
    '  style(DataGrid1, DataSet1.Tables("tabname"))
    '
    '=================================================================

    '列名，字段对应名
    Public strHeaders() As String = {"编号", "时间", "主题", "内容"}
    '列宽,为0隐藏(优先级低于inputnum),对应的列宽
    Public iWidths() As Integer = {0, 70, 130, 0}
    '显示几列,为空则显示所有,为0则隐藏所有
    Public inputnum As String

    Public Sub style(ByVal datagridname As DataGrid, ByVal dataname As DataTable)
        Try
            datagridname.DataSource = dataname
            '显示新增
            'dataname.DefaultView.AllowNew = False
            '在datagrid中直接编辑
            'dataname.DefaultView.AllowEdit = False
            Dim i As Integer
            '处理显示前几列的参数
            If Trim(inputnum) <> "" Then
                Dim num As Integer
                Try
                    num = CInt(Trim(inputnum))
                    Try
                        For i = 0 To iWidths.Length - 1
                            If i >= inputnum Then
                                iWidths(i) = 0
                            End If
                        Next
                    Catch ex As Exception
                    End Try
                Catch ex As Exception
                    MsgBox("你输入的字符不符合要求")
                End Try
            End If
            Dim ts As New DataGridTableStyle
            ts.MappingName = dataname.TableName
            ts.AlternatingBackColor = System.Drawing.Color.PapayaWhip
            ts.BackColor = System.Drawing.Color.WhiteSmoke
            ts.SelectionBackColor = System.Drawing.Color.LightSteelBlue
            ts.SelectionForeColor = Color.Black
            ts.RowHeaderWidth = 10
            ts.PreferredRowHeight = 20
            For i = 0 To dataname.Columns.Count - 1
                Dim ac As New DataGridTextBoxColumn
                '处理点击行
                'AddHandler ac.TextBox.Enter, AddressOf TextBoxEnterHandler
                ac.HeaderText = strHeaders(i)
                ac.MappingName = dataname.Columns(i).ColumnName
                ac.TextBox.Width = iWidths(i)
                ts.PreferredColumnWidth = ac.TextBox.Width
                '哪列,i=第几列数-1
                If i = 1 Then
                    ac.Format = "yyyy-mm-dd hh:mm:ss"
                    'ac.ReadOnly = True
                    'ac.NullText = ""                   
                    ac.Alignment = HorizontalAlignment.Center
                End If
                If i = 1 Or i = 2 Then
                    'ac.ReadOnly = True
                    'ac.NullText = ""                   
                    ac.Alignment = HorizontalAlignment.Center
                End If
                ts.GridColumnStyles.Add(ac)
            Next
            datagridname.TableStyles.Clear()
            datagridname.TableStyles.Add(ts)
        Catch ex As Exception
            MessageBox.Show("格式化网格出错了")
        End Try
    End Sub
