if i am using a frm.Controls.Add(tblOne); instead of frm.Controls.Add(divContent); then it works fine because the tblone doesn’t have any ajax control but in divContent both the table as well as Ajax controls have & it throws the above exception, i have tried many options like overriding OnInit, OnPreRender but doesn’t work for me.
please give a solution to resolve it...
Thanks in advance

if i am using a frm.Controls.Add(tblOne); instead of frm.Controls.Add(divContent); then it works fine because the tblone doesn’t have any ajax control but in divContent both the table as well as Ajax controls have & it throws the above exception, i have tried many options like overriding OnInit, OnPreRender but doesn’t work for me.
please give a solution to resolve it...
