Error converting data type nvarchar to int.

Don't you think that telling us what the error is, is kind of really really really important information to share?

Was that exception generated by the line cmd2.ExecuteNonQuery();?
Somewhere you have a nvarchar column and you are trying to use it as if it was an integer. Post the code from the stored procedure insertDeliveryNote_DetalisTBL2 and include the table schema

cmd2.Parameters.AddWithValue("@Product_Id", GridView1.Rows[y].Cells[0].ToString());

Dear,

The above solution(by @Chill60) will solve your question. So follow the steps what he suggest.

--------------
If there will be more data in gridview then, for every row it will call the stored procedure which may cause of performance issue.

From the below link you can get the idea how you can pass whole grdview data to the stored procedure in one go with out calling stored procedure for each row.
