具有customcontrol属性的数据绑定 [英] Databinding with customcontrol properties

问题描述

嗨！

我创建了customcontrol，其中包括诸如文本块，按钮，滑块等控件.在customcontrol中，我为重要的controlproperties创建了公共属性，我希望向使用我的customcontrol的客户展示给外部.例如我的mycontrol
中的textblock text属性

Hi!

I have created customcontrol which includes controls like textblock, buttons, sliders etc. In customcontrol I have created public properties for vital controlproperties what I like to show outside to client who is using my customcontrol. For example my textblock text property in mycontrol

/// Public property of customcontrol header
public string Header
     {
          get { return txtBlockHeader.Text;  }
          set { txtBlockHeader.Text = value; }
      }

在客户端，我可以看到我的customcontrol，也可以看到我的customcontrol属性"Header"，就像我通常对属性所做的一样，但是，当我尝试在我的dataClass属性和我的customcontrol属性之间设置数据绑定时，我碰壁了.这是我尝试制作绑定的方法

In clientside I can see my customcontrol and I can see my customcontrol property "Header" like I usually do with properties, BUT when I try to set databinding between my dataClass property and my customcontrol property I hit the wall. Here how I try to make bindings

//create bidings between dataClass property and customcontrol property
Binding binding = new Binding("Header");
binding.Mode = BindingMode.TwoWay;
binding.Source = dataClass;

//here I cant find Setbinding method like I usually do...
MyCustomControl.Header.SetBinding(....

希望你有主意:)

干杯！

Hope you got idea :)

Cheers!

推荐答案

尝试将Header属性更改为

Try changing the Header property to,

public string Header
     {
          get { return txtBlockHeader.GetValue(TextBox.TextProperty).ToString();  }
          set { txtBlockHeader.SetValue(TextBox.TextProperty, value); }
      }

您好Raistu，

也许有些误解，但是:
您将Header属性声明为字符串，并希望它具有SetBinding-方法?因此，要么通过Header属性公开TextBlockControl(txtBlockHeader)，要么让Control处理绑定.

Hi Raistu,

Maybe there is some misunderstanding, but:
You declared the Header property as string and expect to have it a SetBinding - method? So either expose the TextBlockControl (txtBlockHeader) through the Header property, or let the Control handle the Binding.
