我看過很多關於此主題的其他帖子,但現在我花了一天多的時間嘗試獲取某些內容,但我會嘗試在這裏提出質疑,並希望你能幫助我。在xaml中使用自定義控件中的C#變量(silverlight)
我想製作一個自定義控件,我可以在屬性菜單中添加值,其中我在項目中添加控件,每次都需要新的東西。
以及info我需要在XAML資源控制,但我不能從C#中的字符串綁定到我在XAML需要:
的C#代碼:
using System;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Ink;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;
using System.Collections.ObjectModel;
using System.ComponentModel;
using System.Windows.Threading;
using WFSilverlight.Shared;
using WFSilverlight.Core;
using System.Collections.Generic;
using System.Linq;
using System.Reflection;
using BG_CalgaryNC_11611.Controls;
namespace BG_CalgaryNC_11611
{
public partial class BG_Calgary_Text_Nav : UserControl
{
//public string NavPage = String.Empty;
[Category("BG")]
public string PageToNavigate { get; set; }
[Category("BG")]
public string DesciptionPageName { get; set; }
[Category("BG")]
public string DisplayName { get; set; }
public BG_Calgary_Text_Nav()
{
InitializeComponent();
NavText.Text = DisplayName;
NavPage = "BG_CalgaryNC_11611_" + PageToNavigate;
//this.DataContext = this;
//NavText.Resources.Add("navPageResourse", NavPage);
//NavText.Resources.Add("displayNameResourse", DesciptionPageName);
}
public string NavPage { get; set; }
}
}
,我想使用「NavPage」和「DesciptionPageName」在xaml中添加。
的XAML代碼:
<UserControl
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"

xmlns:i="http://schemas.microsoft.com/expression/2010/interactivity"
mc:Ignorable="d"
x:Class="BG_CalgaryNC_11611.BG_Calgary_Text_Nav"
d:DesignWidth="640" d:DesignHeight="480">
<Grid x:Name="LayoutRoot" Cursor="Hand">
<Viewbox HorizontalAlignment="Right" VerticalAlignment="Top">
<TextBlock x:Name="NavText" TextWrapping="Wrap" FontSize="10.667" FontWeight="Bold" Text="TC9-21" Height="16" Width="43">
<TextBlock.Resources>
<BG_CalgaryNC_11611_Controls:TranslatableCPNavItem Description="{Binding NavPage, Mode=OneWay}" Source="{Binding DesciptionPageName, Mode=OneWay}" x:Key="target1"/>
</TextBlock.Resources>
<i:Interaction.Triggers>
<i:EventTrigger EventName="MouseLeftButtonUp">
<i:InvokeCommandAction Command="{Binding NavigatToCommand, Mode=OneWay}" CommandParameter="{StaticResource target1}"/>
</i:EventTrigger>
</i:Interaction.Triggers>
<TextBlock.Foreground>
<SolidColorBrush Color="{StaticResource BG_ConnectionArrow_Color}"/>
</TextBlock.Foreground></TextBlock>
</Viewbox>
</Grid>
我可以生成項目,但是當我添加自定義的控制,我得到這個錯誤:類型的
對象system.windows。 data.binding'無法轉換爲類型'system.string'
希望你能幫助我。
