以编程方式将项目添加到数据网格

Question

我在 WPF/VB.NET 中添加了一个数据网格，设法在代码中创建列，但我不知道如何向数据网格添加行。

 Private Sub button_Click(sender As Object, e As RoutedEventArgs) Handles button.Click
    Dim c1 As New DataGridTextColumn()
    c1.Header = "Šifra"
    c1.Width = 100
    c1.Binding = New Binding("Šifra")
    gridRacun.Columns.Add(c1)

    Dim c2 As New DataGridTextColumn()
    c2.Header = "Naziv artikla"
    c2.Width = 500
    c2.Binding = New Binding("Naziv artikla")
    gridRacun.Columns.Add(c2)

    Dim c3 As New DataGridTextColumn()
    c3.Header = "Količina"
    c3.Width = 100
    c3.Binding = New Binding("Količina")
    gridRacun.Columns.Add(c3)

    Dim c4 As New DataGridTextColumn()
    c4.Header = "Cijena"
    c4.Width = 100
    c4.Binding = New Binding("Cijena")
    gridRacun.Columns.Add(c4)


End Sub

如何将字符串添加到每列的数据网格中，字符串是 4 个标签的内容，这些标签会发生变化，单击按钮时我希望将 label1.content 设置为 column1，将 lebel2.content 设置为 column2 等？

Answer 1

您可以通过创建一个包含项目值的类来将自定义项目添加到 DataGrid：

Class Item
    Private _name As String

    Property Name() As String
        Get
            Return _name
        End Get
        Set(ByVal value As String)
            Me._name = value
        End Set
    End Property
    //Some other properties
End Class

现在您可以像这样创建 DataGrid 列：

Dim myColumn As New DataGridTextColumn()

myColumn.Header = "Name"
myColumn.Binding = New Binding("Name")

dataGrid.Columns.Add(myColumn)

您现在可以通过向 DataGrid 添加项目来添加行：

Dim item = New Item With {.Name = "Terry Adams"}
dataGrid.Items.Add(item)

我希望这会有所帮助。
