SQL Server table structure:

CREATE TABLE [dbo].[products] 
(
    [productsID] INT IDENTITY (1, 1) NOT NULL,
    [name] VARCHAR(50) NOT NULL,
    [price] DECIMAL(18, 2) NOT NULL,
    [image] VARCHAR(255) NOT NULL,

    PRIMARY KEY CLUSTERED ([productsID] ASC)
);

I have a gridview which is displaying some data, I am know wishing to enter in some new rows via the details view. For some odd reason I keep getting this error:

Cannot insert explicit value for identity column in table 'products' when IDENTITY_INSERT is set to OFF.

I really don't know what it is causing it to do this, so I'm stuck to for a solution. Any help or advice would be great !

The reason for error is due to the fact that, you are trying to insert values into a table with identity column and SQL is suggesting,if you want to do that,you have to enable 

SET IDENTITY_INSERT ON;

if you don't want insert values into identity column, you can do below

insert into table
(all columns except identity)
values
(col values for all except identity)
