How i can add border to ListViewItem, ListView in GridView mode
提问by Andrew
I want to have a border around ListViewItem (row in my case). ListView source and columns generated during Runtime. In XAML i have this structure:
我想在 ListViewItem 周围有一个边框（在我的例子中是行）。在运行时生成的 ListView 源和列。在 XAML 我有这个结构：
<ListView Name="listViewRaw">
<ListView.View>
<GridView>
</GridView>
</ListView.View>
</ListView>
During Runtime i bind listview to DataTable, adding necessary columns and bindings:
在运行时我将列表视图绑定到数据表，添加必要的列和绑定：
var view = (listView.View as GridView);
view.Columns.Clear();
for (int i = 0; i < table.Columns.Count; i++)
{
GridViewColumn col = new GridViewColumn();
col.Header = table.Columns[i].ColumnName;
col.DisplayMemberBinding = new Binding(string.Format("[{0}]", i.ToString()));
view.Columns.Add(col);
}
listView.CoerceValue(ListView.ItemsSourceProperty);
listView.DataContext = table;
listView.SetBinding(ListView.ItemsSourceProperty, new Binding());
So i want to add border around each row, and set border behavior (color etc) with DataTriggers (for example if value in 1st column = "Visible", set border color to black). Can i put border through DataTemplate in ItemTemplate? I know solution, where you manipulate with CellTemplates, but i don't really like it. I want something like this if this even possible.
所以我想在每一行周围添加边框，并使用 DataTriggers 设置边框行为（颜色等）（例如，如果第一列中的值 =“可见”，则将边框颜色设置为黑色）。我可以通过 ItemTemplate 中的 DataTemplate 放置边框吗？我知道解决方案，您可以在其中使用 CellTemplates 进行操作，但我真的不喜欢它。如果可能的话，我想要这样的东西。
<DataTemplate>
<Border Name="Border" BorderBrush="Transparent" BorderThickness="2">
<ListViewItemRow><!-- Put my row here, but i ll know about table structure only during runtime --></ListViewItemRow>
</Border>
</DataTemplate>

Assuming you're using a ListView with a GridView set as the View, then the ListView doesn't show vertical or horizontal lines by default.
假设您使用的 ListView 将 GridView 设置为 View，则默认情况下 ListView 不会显示垂直或水平线。
If you want to add horitzontal lines then you can change the border on the ListViewItem, e.g:
如果要添加水平线，则可以更改 ListViewItem 上的边框，例如：
<ListView ...>
<ListView.ItemContainerStyle>
<Style TargetType="{x:Type ListViewItem}">
<Setter Property="BorderBrush" Value="LightGray" />
<Setter Property="BorderThickness" Value="0,0,0,1" />
</Style>
</ListView.ItemContainerStyle>
<ListView.View>
<GridView>
<GridViewColumn ... />
</GridView>
</ListView.View>
...

You'll have to set your border in the ControlTemplate
您必须在 ControlTemplate 中设置边框
<Style x:Key="BorderedItem" TargetType="ListViewItem">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="ListViewItem">
<Border Name="Border" BorderBrush="Transparent" BorderThickness="2">
<ContentPresenter />
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Now you can set this style in your ListView
现在您可以在 ListView 中设置此样式
<ListView ItemContainerStyle="{StaticResource BorderedItem}" />
