I have a partial class with no constructor code. I want to add constructor code but is it possible to add this constructor in another class which is a part of this partial class.

add this constructor in another class
No, you can't.
But in the same partial class or may be on a different file, yes
public partial class Test
{
}
public partial class Test
{
public Test()
{
}
}

So this means another partial class with the same name.

+1. @RPK, no it means the same class implemented in separate files by using
partial to split implemetation between files.

partial class is a single class, split over multiple source files or same file like above, see msdn.microsoft.com/en-us/library/wa80x488(v=vs.80).aspx
You can add a constructor to a partial class, if your class is partial to that class!
Here's an example of what you can do:
public partial class Test
{
public string Name { get; set; }
public Test(string name, int age)
{
Name = name;
Age = age;
}
}
public partial class Test
{
public int Age { get; set; }
public Test(string name)
{
Name = name;
}
}
Essentially this would be the same as doing:
public class Test
{
public int Age { get; set; }
public string Name { get; set; }
public Test(string name)
{
Name = name;
}
public Test(string name, int age)
{
Name = name;
Age = age;
}
}

I have a problem. The other partial class (with Constructor) is also with the same name but I am unable to access the properties of old partial class. While creating instance, it is red-underlined.
It is not possible to add constructor for a class in another class.
What is possible it to have constructor for a class that consist from several files wiht partial class in any of the files for this partial class.

If i understand the question correctly, the answer is that you can add the constructor in any side of the partial class you wish. But you cant add it in a nested class that exists in your partial class, as that is a totally different class. Examples are provided on the official msdn site that make it clear.
public partial class <yourclass>and make sure you specify the same namespace as in generated class
