Hi krish456,
According to your description, after you move SSRS report from one server to another, you got the error message when you preview the repot: Type 'System.Web.UI.WebControls.PlaceHolder' does not have a public property named 'style'.
As per my understanding, you are using object of System.Web.UI.WebControls.PlaceHolder while a different type was expected, this different type has style properties, which were needed for the report to run properly. It seems that you should be using System.Web.UI.WebControls.Style.
Reference:
PlaceHolder Class
Style Class
If you have any more questions, please feel free to ask.
Thanks,
