问题描述
我有一个包含报价的数据库应用程序.每个报价都有一个状态.有5种可能的州，每个报价都分配给一个州，也只有一个州.
I have a database application containing Quotations. Each Quote has a State. There are 5 possible states and each Quote is assigned to one and only one State.
状态是连续的(报价，接受，开始，完成，交付和开票)，我想使用滑块控制报价的当前状态.
The States are sequential (Quoted, Accepted, Started, Completed, Delivered and Invoiced) and I would like to use a Slider to control the current State of a Quote.
但是，滑块控件只是表示一个标量，与List或ComboBox控件不同，它没有多个项目或选择的概念.国家不仅是一个标量，而且是一个实体，那么我该如何绑定它呢?我想我需要根据 Slider可以满足我的要求，但我不知道从哪里开始.我直接基于Control类开发了简单的UserControls和其他控件，但是在这里我不胜枚举.
However, the slider control simply represents a scalar and, unlike a List or ComboBox control has no notion of multiple items or selection. The State is an entity not just a scalar, so how do I bind it? I guess I will need to develop a control, based on the Slider, that will do what I want but I've no idea where to start.I have developed simple UserControls and other controls based directly on the Control class, but am out of my depth here.
有人知道吗?
- 是否已经实现了带有ItemSource和列表绑定支持的Slider?
- 在创建此类控件时，我可以在哪里寻求指导?
- Has a Slider with ItemSource and list binding support been implemented already?
- Where might I go for guidance in creating such a control?
推荐答案
由于滑块仅具有 Value -属性，因此我将设置其 Minimum / Maximum 以及 SmallChange / LargeChange 属性，以便可能的值范围与您的状态相符，然后使用转换器来来回传递这些值.绑定它们.
since the Slider only has the Value -property, I would set its Minimum /Maximum as well as theSmallChange /LargeChange properties so that the range of possible values is in accordance with your states and then use a converter to transfer the values back and forth resp. bind them.
