Dear Friend,

This error mainly occurs when you are trying to insert a nvarchar value into a data field of type int.

Check with your sql table that which fields are of type int and at the same time check from your code that you are entering correct entry into the field types.

This is a generalized error. Please follow the link for more explanation:-

I thought u have nvarchar data in your table and int datatype on c# code page. this conversion is not allowed because there are some Alphabet. Make sure you dont have them.
