Update button Condition

private void btnUpdate_Click(object sender, EventArgs e)

{

Entity ent = new Entity();

BAL b = new BAL();

ent.intId = (int)gvData.SelectedRows[0].Cells["Id"].Value;

if (ent.intId != 0)

{

ent.strEmail = txtEmail.Text;

ent.strName = txtName.Text;

ent.strSalary = txtSalary.Text;

DL dl = new DL();

dl.Update(ent);

DataTable dt = dl.Display(ent);

gvData.DataSource = dt;

}

b.Clear(ent);

txtEmail.Text = txtName.Text = txtSalary.Text = " ";

}

Hello,

This is my Code for update. Now i want to put condition for update. Like if I put new record and by mistake I click Update then I got ("Index was out of range. Must be non-negative and less than the size of the collection.") Error. So I want to remove it.

If you have any idea then Please Suggest.

Thanks in advance

You can check with identity column of table and their value if it is less than or equal to 0 then add else update as shown below-
if(ent.intId>=1)
{
  dl.Update(ent);
}
else
{
dl.Insert(ent); //Or whatever you may want
}
