"groupid").Style.Add("visibility", "hidden")

this worked just fine.

I then needed to set this row to be editable.  (I have the grid to edit inplace). In the ItemDataBound handler, after I set the styles like the one above, I set the row to be editable:

dataitem.edit = true

Initially I did not see the cells become editable (showing textboxes instead of  labels).
After reading in the documentation that I need to rebind the grid after I change the edit property, I placed a rebind() in the page's PreRenderComplete handler:  

Me

.PreRenderComplete

This now shows the editable columns in the row BUT all of the style changes that I did in the ItemDataBound handler are lost. If I take out the rebind() in the PreRenderComplete the style changes are made but the editable columns are not set.

Is there a way to both set the style of a row dynamically and set it to be editable?

function OnClientDragEnd(sender, eventArgs)

{
sender.set_enableDrag =

false;

sender.set_closed =

true;

sender_dockMode = 0;

}

but nothing heppens.  The Dock ist still enabled and opend?

Thanks for your Help
