Hi ,

i have the below controller

[HttpPost, Route("EmployeeProfile")]

public HttpResponseMessage Create(HR_EmployeeProfile EmployeeProfile)

{

return Request.CreateResponse(HttpStatusCode.OK, _EmployeeProfileManager.Create(EmployeeProfile));

}

and i have the below aspx page

protected void BtnSaveEmpDet_Click(object sender, EventArgs e)

{

var emp = new EmployeeProfile();

emp.MiddleName = txtMiddleName.Text;

emp.LastName = txtLastname.Text;

emp.Add_Street1 = txtAddStreet1.Text;

emp.Add_Street2 = txtAddStreet2.Text;

emp.Add_City = txtAddCity.Text;

emp.Add_State = txtAddState.Text;

emp.Email = txtEmail.Text;

}

where EmployeeProfile is a model and i am assigning the input values from textboxes and assigning them to the field values in the model. Now, i want to send the emp object to the controller for creating the profile.

how could i do that?

Make sure that WebAPI in running mode or you can host in IIS.

Secondly, if it is not perfect you should get exception. please debug and see the exception details.

Hi Manas

I have tried using httpclient .. below is the code

protected void BtnSaveEmpDet_Click(object sender, EventArgs e)
{

HttpClient client = new HttpClient();
client.BaseAddress = new Uri("http://localhost:1794/");
client.DefaultRequestHeaders.Accept.Clear();
client.DefaultRequestHeaders.Accept.Add(
new MediaTypeWithQualityHeaderValue("application/json"));
var emp = new HR_EmployeeProfile();
emp.FirstName = txtFirstName.Text;
emp.MiddleName = txtMiddleName.Text;
emp.LastName = txtLastname.Text;
emp.Add_Street1 = txtAddStreet1.Text;
emp.Add_Street2 = txtAddStreet2.Text;
emp.Add_City = txtAddCity.Text;
emp.Add_State = txtAddState.Text;

var response =client.PostAsJsonAsync("api/EmployeeProfile", emp).Result;
}

But it is not calling the controller
