How to set a Property ReadOnly dynamically based on another property value.

[srinivas2009123]

Hi,

I have a class with two Properties like HasSubMenu, and SubMenu , object of this class is bound to property grid. The class is given below.

class test
{

    private bool m_HasSubMenu;
    private string m_SubMenu;
     
    [Browsable(true)]
    public bool HasSubMenu
    {
        get { return m_HasSubMenu; }
        set { m_HasSubMenu = value; }
    }

     
    [Browsable(true)]
    [ReadOnly(true)]
    public List<Menu> SubMenu
    {
        get { return m_SubMenu; }
        set { m_SubMenu = value; }
    }

}

This object of this class (initially with HasSubMenu false and an empty SubMenu string ) is bound to a property grid. Now that I have a ReadOnlyAttribu te set for SubMenu property this string is read only and user can't edit in the property grid. But what I want is if the user changes the HasSubMenu property to true I want this string to be editable (I mean somehow I want to make this ReadOnly attribute of SubMenu property false.)



I am not able to figure out how should I do this. Any help will be highly appreciated



Thanks and Regrads

Plan B

Instead of worrying about making your List<> read only, just focus on making the control it is attached to read-only. Its a lot easier since most controls have a property for this.
