更改GridView标题高度(Change GridView Header Height)

更改GridView标题高度(Change GridView Header Height)

我想改变我的GridView的高度，在XAML中我使用以下代码：

<Window.Resources> <Style x:Key="myHeaderStyle" TargetType="{x:Type GridViewColumnHeader}"> <Setter Property="Height" Value="45"></Setter> </Style> </Window.Resources> <ListView x:Name="LView"> <ListView.View> <GridView x:Name="GView" ColumnHeaderContainerStyle="{StaticResource myHeaderStyle}"></GridView> </ListView.View> </ListView>

但是，如果我想动态地这样做？ 我试过了：

Style style = new Style(); style.TargetType = typeof(GridViewColumnHeader); style.Setters.Add(new Setter(GridViewColumnHeader.HeightProperty, 155)); GView.ColumnHeaderContainerStyle = style;

但是我有一个ArgumentException（值155不是有效值）。 为什么？ 我怎么解决这个问题？ 谢谢。

But if I want to do this dynamically? I tried:

Style style = new Style(); style.TargetType = typeof(GridViewColumnHeader); style.Setters.Add(new Setter(GridViewColumnHeader.HeightProperty, 155)); GView.ColumnHeaderContainerStyle = style;

But I have an ArgumentException (the value 155 is not a valid value). Why? How can i solve this problem? Thanks.

最满意答案

FrameworkElement.Height需要一个double值，因此您需要将155作为double传递给：

style.Setters .Add(new Setter(GridViewColumnHeader.HeightProperty, 155d));

要么

style.Setters .Add(new Setter(GridViewColumnHeader.HeightProperty, 155.0));

FrameworkElement.Height expects a double value so you need to pass 155 as a double with:

style.Setters .Add(new Setter(GridViewColumnHeader.HeightProperty, 155d));

Or

style.Setters .Add(new Setter(GridViewColumnHeader.HeightProperty, 155.0));
