WPF滑块控件的DataBinding Tick属性 [英] DataBinding Tick Property of WPF slider control

问题描述

我正在尝试探索滑块控件.目前，我需要将滑块控件用作导航控件.为此，我想将滑块控件的Tick属性数据绑定到集合.

Ticks属性是一个依赖项属性，因此它应该能够接受绑定.

这就是我在做什么.

我有一个带有List< Object>的类myCollectionClass.物业

I am trying to explore the slider control. Currently I have a requirement to use the slider control as navigation control. For that I want to databind the Tick property of the slider control to a collection.

The Ticks property is a dependency property and so it should be able to accept bindings.

This is what I am doing.

I have a class myCollectionClass with a List<Object> Property

public List<double> myCollection
        {
            get
            {
                List<double> myList = new List<double>();
                myList.Add(1);
                myList.Add(2);
                myList.Add(3);
                myList.Add(4);
                return myList;
            }
        }

我想将壁虱数据绑定到myCollection

这就是我在XAML中所做的

I want to databind the ticks to myCollection

This is what I have done in XAML

<Window.Resources>
        <c:myCollectionClass x:Key="CollClass"/>
    </Window.Resources>

<Grid DataContext="{StaticResource CollClass}">
        <StackPanel Grid.Row="1">
            <Slider TickPlacement="BottomRight"

                    IsSnapToTickEnabled="True"

                    Ticks="{Binding myCollection}"/>
        </StackPanel>
    </Grid>

这不起作用.

如果我说-

This does not work.

If I say -

<Slider TickPlacement="BottomRight" 

                    IsSnapToTickEnabled="True"

                    Ticks="1,2,3,4,5"/>

它工作正常，但我正在尝试将Ticks绑定到该集合.

知道如何实现吗?

it works fine, but I am trying to bind the Ticks to the collection.

Any idea how to achieve this?

推荐答案

在我看来，Ticks接受DoubleCollection类型的值.

我尝试手动进行操作，发现Ticks不能接受Type List的值.

所以我认为您可以替换List< double>与DoubleCollection.基本上，DoubleCollection是非泛型的，并且仅采用数据类型Double的值以及其OrderedCollection！

因此属性应如下所示:

In my opinion, the Ticks takes values of type DoubleCollection.

I tried doing it manually and found that Ticks cannot take values of Type List.

So what i think is that you can replace the List<double> with DoubleCollection. Basically DoubleCollection is non-generic and takes only values of Datatype Double and also its an OrderedCollection!

So the property should be like this:

public DoubleCollection myCollection
        {
            get
            {
                DoubleCollection myList = new DoubleCollection();                
                myList.Add(1);
                myList.Add(2);
                myList.Add(3);
                myList.Add(4);
                return myList;
            }
        }
