我有一個從Control類派生的自定義無標頭控件。它的模板在Generic.xaml文件中定義。現在我想添加一些UI的東西(主要是刷子),並希望在單獨的資源字典中做到這一點,然後從代碼隱藏代碼(* .xaml.cs)中訪問這些東西。 參見波紋管: Generic.xaml(片段):如何從代碼隱藏文件中的合併ResourceDictionary中獲取資源?
<ResourceDictionary
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:PTE.Controls" xmlns:sys="clr-namespace:System;assembly=mscorlib">
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="PTE.Controls;component/Resources/CategoriesColors.xaml"/>
</ResourceDictionary.MergedDictionaries>
<CornerRadius x:Key="elementCornerBorder" BottomLeft="2" BottomRight="2" TopLeft="2" TopRight="2"/>
<Style TargetType="{x:Type local:Element}">
<Setter Property="Canvas.ZIndex" Value="50"/>
<Setter Property="MinWidth" Value="60"/>
<Setter Property="Template">...
CategoriesColors.xaml(片段):
<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<LinearGradientBrush StartPoint="0,1" EndPoint="1,0" x:Key="categoryNobleGas">
<GradientStop Color="White" Offset="0"/>
<GradientStop Color="RoyalBlue" Offset="0.5"/>
<GradientStop Color="SteelBlue" Offset="1"/>
</LinearGradientBrush>...
服務器側部分(片段):
private static void OnCategoryNameChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
{
var categoryName = (CategoryName)e.NewValue;
var element = (Element) d;
switch (categoryName)
{
case CategoryName.NobleGas:
element.Background = (Brush)element.TryFindResource("categoryNobleGas");
break;
case CategoryName.Halogen:
element.Background = (Brush)element.TryFindResource("categoryHalogen");
break;
case CategoryName.OtherNonmetal:
element.Background = (Brush)element.TryFindResource("categoryOtherNonmetal");
break;
case CategoryName.Metalloid:
一點也沒有」工作。基本上TryFindResource方法總是返回null。任何想法如何使這些東西一起工作? 謝謝!
UPD:如果我添加以下在它的工作原理控制的構造線:
this.Resources = Application.LoadComponent(new Uri("PTE.Controls;Component/Resources/CategoriesColors.xaml", UriKind.Relative)) as ResourceDictionary;
但首先,它會複製詞典(每次加載新的),並消耗大量的內存。其次,我真的想在XAML中做到這一點。
Nope :(沒有幫助:( – 2010-09-24 16:11:28
