I know English is not your primary language, but you will need to try and clarify your thread. It makes no sense and you won't get much help on it.

Probably someone could, you need to clarify your question like you have already been told. Post the code that you have written that demonstrates your problem and then describe the problem that you have. At least Abhinav tried to answer you.

aboe code error in drop downlist coding..

And where does this error come from? You are not using > anywhere in this code so.... And the error means exactly what it says, a string cannot be compared to an int by using >. A string could not be greater than, less than or equal to any integer. And to top it all off, this is a button click event not a drop down list anything.
