Get Location of user control in wpf

if you want to set location change:
public form1()
{
initializecomponent();
}

to

public form1( int x, int y)
{
 initializecomponent();
this.location=new point(x,y);
}

but if you want to change the size just replace:

this.location=new point(x,y);

with

this.size=new size(x,y);

so when you call to open form call it like:
form1 f1=new form1(150,150);
f1.show();
