c# - XAML Binding multiple sources -

ok, have set of textblock's.

<grid x:name="mygrid">    <textblock text={binding value1} />    <textblock text={binding value2} /> </grid> 

and c# backend:

mydata.value1 = "value1"; mydata.value2 = "value2"; mygrid.datacontext = mydata; 

now, want bind blocks foreground color this:

//c# private bool isviewingpage1; private bool isviewingpage1 {    { return this.isviewingpage1; }    set    {       this.isviewingpage1 = value;       notifypropertychanged();    } }  //xaml <grid x:name="mygrid">    <textblock text={binding value1} foreground={binding isviewingpage1, converter={staticresource myconverter}} />    <textblock text={binding value2} foreground={binding isviewingpage1, converter={staticresource myconverter}} /> </grid> 

so, in case if isviewingpage1 == true, first textblock green , second red. if false, first red , second - green. converters working good. how can bind 2 different values 1 element?

i tried this:

public class myclass : inotifypropertychanged {    public mydatatype mydata;    public bool isviewingpage1;     //inotifypropertychanged implemetation }  //...  myclass = new myclass(); a.mydata = mydata; a.isviewingpage1 = isviewingpage1; mygrid.datacontext = a;  //xaml <grid x:name="mygrid">    <textblock text={binding mydata.value1} foreground={binding isviewingpage1, converter={staticresource myconverter}} />    <textblock text={binding mydata.value2} foreground={binding isviewingpage1, converter={staticresource myconverter}} /> </grid> 

...but did not me. ideas?

the logic determine colour, or @ least status (colour should view specific not defined in model) of text blocks should in view model. can have status each text block , bind them, in view model can set statuses of text blocks based on isviewingpage bool.
