Question

我已经通过将数据绑定到数据库列成功地在datagrid中显示数据，但问题是，所有数据列在完全显示之后出现两次即（id，user_id，status，id，user_id，status，）。除此之外，这是我的代码

<DataGrid x:Name="Grid_display" Grid.ColumnSpan="3" Margin="63,51,36,10" Grid.RowSpan="2">
                <DataGrid.Columns>
                    <DataGridTextColumn Header="ID" Binding="{Binding Path=id}"/>
                    <DataGridTextColumn Header="Publisher ID" Binding="{Binding Path=user_id}"/>
                    <DataGridTextColumn Header="Publication Title" Binding="{Binding Path=title}"/>
                    <DataGridTextColumn Header="Published Date of Document" Binding="{Binding Path=published_date}"/>
                    <DataGridTextColumn Header="File" Binding="{Binding Path=file}"/>
                    <DataGridTextColumn Header="Status" Binding="{Binding Path=status}"/>

                </DataGrid.Columns>
            </DataGrid>

 private void display_btn_Click(object sender, RoutedEventArgs e)
        {
            List<publication> q = (from p in db.publications where p.user_id == get_id select p).ToList();
            Grid_display.ItemsSource = q;

        }

您必须在数据网格上设置AutoGenerateColumns="False"。默认情况下，它是真的，并且正在添加另一组列。

<DataGrid x:Name="Grid_display" Grid.ColumnSpan="3" AutoGenerateColumns="False" 
          Margin="63,51,36,10" Grid.RowSpan="2"/>
