Assign Value To User Control Using Inline Code

I have a simple user control (myControl.ascx) , in the myControl.ascx.cs file, I defined:

public string sUserName
{
get
{
return _sUserName;
}
set
{
_sUserName = value;
populateData();
}
}

In one of my aspx page, I use this control:

[Code]....

myNameSapce.Config.sType is a public value from a class, I just can't get that value for above inline code, is it possible to do that? Otherwise, I need go to the .cs file to do this: myControl1.sUserType = myNameSapce.Config.sType; But still hope I can do the inline code.
