Hi experts,
I recently started working in asp.net c#. right now working on a sample project but having some trouble. When i insert the data into database nothing gets inserted except for that table's primary key without any error. here is the code.
database table
CREATE TABLE [dbo].[product] (
[p_id] INT IDENTITY (1, 1) NOT NULL,
[p_name] VARCHAR (50) NULL,
[description] VARCHAR (MAX) NULL,
[datetime] VARCHAR (50) NULL,
[image] VARCHAR (50) NULL,
[p_price] VARCHAR (50) NULL,
[quantity] INT NULL,
[category] VARCHAR (50) NULL,
CONSTRAINT [PK_product] PRIMARY KEY CLUSTERED ([p_id] ASC)
);

SqlCommand cmd = new SqlCommand(str, con);
cmd.ExecuteNonQuery();
con.Close();
}
i've been through so many tutorials and lectures but nothing is of real help until now.
please take a look at this and tell me where I am going wrong and why the garbage values are getting inserted in to the database. I expect a quick responose brothers. it'll be a lot of help.
Thanks
