Hi
I'm converting a vb6 project to .Net. In vb6 I had a frame with many text boxes and other ctrls. whenever I disabled the frame I would have access to text boxes or other ctrls.for instance I could select the text inside the textbox even I couldn't change anything.But now in vb.Net all ctrls will be gray out and inaccessible. Is there anyone who over come this incompatibility?

public bool ReadOnly
{
get
{
return m_readOnly;
}
set
{
m_readOnly = value;
foreach (Control ctrl in Controls)
{
PropertyDescriptorCollection properties = TypeDescriptor.GetProperties(ctrl);
PropertyDescriptor pd = properties.Find("ReadOnly", false);
if (!object.ReferenceEquals(pd, null))
{
pd.SetValue(ctrl, m_readOnly);
}
}
}
}
Once you have your custom panel, you can "enable/disable" by setting the new ReadOnly property on your own panel class. In turn, your panel class will cascade the ReadOnly setting to all controls contained if they support it. Same thing can be done for other containers. Have fun.
