hi, i got master page in root of my project. Then i create a postbackurl in 2 webforms and retrieve all the control i want. This method still work when all the webforms in root. when i create a folder and i put in 2 forms, then it cannot retrieve the control. Here my problem

error message =child request for handler 'ASP....'
Dim ct As ContentPlaceHolder
ct = CType(PreviousPage.Master.FindControl("ContentPlac eHolder1"), ContentPlaceHolder)

This coding in root, it work, when i apply this method inside sub folder it cannot work. how i find the control in subfolder when the forms using master page???

This problem happen when i create straight in sub folder... when i create this method in root which can work, then i cut and paste to the sub folder, it still working... I should bang to wall already... maybe some path mapping to master page need to change when i straight create in sub folder .... Problem solve...
