c# - Binding chain with slider and text box in wpf -

i binding below:

a (in view) <---> b (in view) <----> c (mydata)

binding a-b : 2 way

binding b-c : 1 way

xaml

<slider x:name="slider" minimum="0" maximum="100" value="{binding path=text, elementname=textbox, mode=twoway}"/> <textbox x:name="textbox" text="{binding path=myvalue, mode=oneway}"/> <button x:name="button" content="button" click="button_click"/> 

code behind:

public int myvalue {     { return m_value; }     set     {         m_value = value;         notifypropertychanged("myvalue");     } } ... private void button_click(object sender, routedeventargs e) {     myvalue = 10; } 

i expect when click on button, value of text box , slider bar updated. however, nothing happen.

please me solve problem. thank in advance.

what trying wrong in architecture, that's why suggest take @ documentation mvvm

such as: https://www.codeproject.com/articles/819294/wpf-mvvm-step-by-step-basics-to-advance-level

or instead of considering prism there more powerful more approchable , easier such mvvmlight: http://www.dotnetcurry.com/wpf/1037/mvvm-light-wpf-model-view-viewmodel

hope having been useful
