You are trying to convert a non-integer value into an Integer. :)

I have String Column in my Database Table and i checked my entire coding also

like this

I have used a Telerik Asp.net Mvc based Combobox(Size)  to  Saving User Entered Data

In That if user enter integer like 12 or .... it  saving the data to database table perfectly

but user enter A12 or abc its make a Error  "input string was not in a Correct Format"

Anybody have solution for this

You put your parameter as Integer, but your database (of the same field) is string.

And you try to convert 'A12' into an integer, which of course will throw error. Just change your parameter to String, since the corresponding field in Database is a String also. :)
