Question

我在datagrid wpf

中有这些列

        <DataGrid.Columns>
            <DataGridComboBoxColumn SelectedItemBinding="{Binding Path=ProductId}" DisplayMemberPath="Name" SelectedValuePath="Id" />         
            <DataGridTextColumn Binding="{Binding Path=StorageAmount}" Width="*" Header="Со склада" />
            <DataGridTextColumn Binding="{Binding Path=Trade1Amount}" Width="*" Header="С точки 1" />
            <DataGridTextColumn Binding="{Binding Path=Trade2Amount}" Width="*" Header="С точки 2" />
            <DataGridTextColumn Binding="{Binding Path=TotalAmount}" Width="*" Header="Всего" FontWeight="Bold" />
        </DataGrid.Columns>

如何以编程方式从代码绑定 DataGridComboBoxColumn ，而不是从xaml绑定？我无法将 Name 定义为 DataGridComboBoxColumn ，因此我无法从代码访问以填充此Combobox的 DataContext

Answer 1

将x：-namespace与Name-attribute一起使用。这将做你想要的：

<DataGridComboBoxColumn x:Name="m_yourComboBoxColumn" SelectedItemBinding="{Binding Path=ProductId}" DisplayMemberPath="Name" SelectedValuePath="Id" />

从代码绑定DataGridComboBoxColumn
