Sandeep Mewara thank you. in the link above there is a sample code, it is for cascading drop down list filled by AJAx, Javascript. The code get data from webservice properly but it can not do postback and cause error. Just download the code, put a button on it, run the code and click to see error.

Hi again:
As I check, only whet table is empty it raise error with cast. I changed my cast but I have problem:
Convert.ToBoolean(Eval("CanSee"))?"~/ServerFile/Icons/Editor/True.png":"~/ServerFile/Icons/Editor/False.png"
Error:
Object cannot be cast from DBNull to other types.

This is error:
Exception Details: System.InvalidCastException: Specified cast is not valid.
More information: since the field in grid in null, the cast face error and since the eval("CanPrint") is boolean I don't know how to avoid it.
It seems that I must check null value before using cast, but I don't know how?
Thanks
