INDENTITY INSERT must be ON for the table you want to insert an explicit value, not OFF.

It can only be ON for one table. So the usual way to handle it is to set it OFF, then ON for the table needed.

Strange - you don't actually set the identity column from your code according to the code you provide.
Have you edited anything out from the code you pasted ?

You state, "i get this error when i insert data in sql.", Please post the exception message and the inner exception message.

I agree with Olaf...

SET IDENTITY_INSERT dbo.tbl_patient ON

 Run this Query on SSRS , the sqlserver query editor

Make sure your table name is correct.

@dejaanbu, I agree with Olaf...
Please read the question

Identity column is: patientid
              Tblpatient.firstname = textfirstname.Text;
                Tblpatient.lastname = textlastname.Text;
                Tblpatient.bdate =Convert.ToDateTime(bdate.Text);
                Tblpatient.gender = cmbgender.Text;
                Tblpatient.SSN = txtssn.Text;
                Tblpatient.address = txtaddress.Text;
                Tblpatient.country = cmbcountry.Text;
                Tblpatient.state = cmbstate.Text;
                Tblpatient.city = cmbcity.Text;
                Tblpatient.mobileno =Convert.ToInt32 (txtcnno.Text);


Where is it being set in that code ?

Good question, Andy. Patientid is not set in that code, so indeed the submit/insert should work with IDENTITY_INSERT set OFF. Somehow the mapping of the datacontext has not set patientid as a value not written in the insert. That would cause such an error, no matter what default value that column would have on the  DotNet tblPatient object.

Bye, Olaf.

Do you really want to set the patientid? As it's defined as a identity in the database, it's generated (incremented) by the database. Your code isn't wrong. What is wrong is the mapping. You have to find code specifying patientid, it should be specified in c# in a way to not put this column into the generated insert sql statement, which the SubmitChanges() causes.

Bye, Olaf.
