Hi, 

I am about to develop a new website. I have set the DisplayMode property to Design, so that I can move around the web parts. But I don't want the right side web parts to be moved to the center area webzones and vice versa. 

How can I tackle this problem. Please let me know if further detail is required.

Regards, 

webpart has a property, allowzonechange, set that propert to false for those webparts which you don't wants to move.

foreach(WebPart wp in WebPartZone1.WebParts)

  wp.AllowZoneChange = false;

It is valuable information but my problem is not solved yet.

What I want is to stop only some webparts to be moved to particular webzones.

For example, I have 4 zones. I can move 2nd and 3rd webparts to zone 1 but not 4th. Now how to restrict only this 4th webpart from moving there to 1st.

I hope it's much more clear now.

foreach(WebPart wp in WebPartZone1.WebParts)
{
   if(wp.Title == "your unwanted move webpart title here")
       wp.AllowZoneChange = false;
}
