Question

有一个DataGridView在运行时创建，从数据库中获取数据。数据网格视图中有四种类型的列：

DataGridViewTextBoxColumn
DataGridViewComboboxColumn
DataGridViewButtonColumn
DataGridViewCheckBoxColumn

创建datagridview的代码如下：

    _form.DGV_.AutoGenerateColumns = False
    _form.DGV_.Columns.Clear()

    'Required Variables
    Dim pom_DataGridViewTextBoxColumn As DataGridViewTextBoxColumn = Nothing
    Dim pom_DataGridViewComboBoxColumn As DataGridViewComboBoxColumn = Nothing
    Dim pom_DataGridViewButtonColumn As DataGridViewButtonColumn = Nothing
    Dim pom_DataGridViewCheckBoxColumn As DataGridViewCheckBoxColumn = Nothing

    'Column-1 (ID: jntDate)
    pom_DataGridViewTextBoxColumn = New DataGridViewTextBoxColumn
    pom_DataGridViewTextBoxColumn.DataPropertyName = "jntDate"
    pom_DataGridViewTextBoxColumn.HeaderText = "Date"
    pom_DataGridViewTextBoxColumn.DefaultCellStyle.Format = "d"
    _form.DGV_.Columns.Add(pom_DataGridViewTextBoxColumn)

    'Column-2 (ID: jntAcc)
    pom_DataGridViewComboBoxColumn = New DataGridViewComboBoxColumn
    pom_DataGridViewComboBoxColumn.DataPropertyName = "jntAcc"
    'Cond: If dataset Acc does not contain any table then add table from database.
    If Acc.Tables.Count > 0 Then
        pom_DataGridViewComboBoxColumn.DataSource = Acc.Tables.Item(0)
    Else
        Acc.Tables.Add(Tbl_Select("SELECT *, accNo AS byNo, accName as byName FROM tblAccounts", False, ""))
        pom_DataGridViewComboBoxColumn.DataSource = Acc.Tables.Item(0)
    End If
    'Cond: If _Account_Name_Number is True then set DisplayMember property to 'byName'.
    If _Account_Name_Number Then
        pom_DataGridViewComboBoxColumn.DisplayMember = "byName"
    Else
        pom_DataGridViewComboBoxColumn.DisplayMember = "byNo"
    End If
    pom_DataGridViewComboBoxColumn.ValueMember = "accID"
    pom_DataGridViewComboBoxColumn.HeaderText = "Account"
    _form.DGV_.Columns.Add(pom_DataGridViewComboBoxColumn)


    'Column-3 (ID: xxxx)
    pom_DataGridViewButtonColumn = New DataGridViewButtonColumn
    pom_DataGridViewButtonColumn.DataPropertyName = "xxxx"
    pom_DataGridViewButtonColumn.UseColumnTextForButtonValue = True
    pom_DataGridViewButtonColumn.HeaderText = "X"
    pom_DataGridViewButtonColumn.Text = "X"
    pom_DataGridViewButtonColumn.Width = 32
    pom_DataGridViewButtonColumn.DefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleCenter
    pom_DataGridViewButtonColumn.DefaultCellStyle.ApplyStyle(pom_DataGridViewButtonColumn.DefaultCellStyle)
    _form.DGV_.Columns.Add(pom_DataGridViewButtonColumn)

    'Column-4 (ID: jntReview)
    pom_DataGridViewCheckBoxColumn = New DataGridViewCheckBoxColumn
    pom_DataGridViewCheckBoxColumn.DataPropertyName = "jntReview"
    pom_DataGridViewCheckBoxColumn.HeaderText = "Review"
    pom_DataGridViewCheckBoxColumn.DefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleCenter
    pom_DataGridViewCheckBoxColumn.DefaultCellStyle.ApplyStyle(pom_DataGridViewCheckBoxColumn.DefaultCellStyle)
    _form.DGV_.Columns.Add(pom_DataGridViewCheckBoxColumn)

在WPF应用程序中，需要使用这四列填充相同的DataGrid。如何在WPF中的DataGrid中创建数据并将数据绑定到四种类型的列？

Answer 1

为什么不跳过cs代码中的所有内容呢？当数据网格需要更复杂的模板，数据触发器，自定义样式，动画等等时，你会开始将自己固定在角落里并且会碰到墙壁......此外，它不仅会让下一个人更容易，而且会更容易你也是。当你必须在3-6个月后在.cs代码中创建的野兽中添加/修复某些东西时，可能需要一段时间来了解发生了什么：）

相反，在xaml中完成所有工作，创建UserControl，将此数据网格放入其中，将DataContext从UserControl的各种实例传递到它的DataGrid。
