Using EditItemTemplate for InsertItemTemplate in FormView (ASP.NET)

There is a nice way to reuse your hardly made EditItemTemplate in the InsertItemtemplate. Found in ASP.NET forum:

protected void FormView1_Init(object sender, EventArgs e) {

   FormView1.InsertItemTemplate = FormView1.EditItemTemplate

}

protected void FormView1_DataBound(object sender, EventArgs e) {     

  if (FormView1.CurrentMode == FormViewMode.Edit) {

       LinkButton InsertButton = FormView1.FindControl("InsertButton") as LinkButton;

       LinkButton UpdateButton = FormView1.FindControl("UpdateButton") as LinkButton;

       InsertButton.Visible = false;

       UpdateButton.Visible = true;

  } else if (FormView1.CurrentMode == FormViewMode.Insert) {

       LinkButton InsertButton = FormView1.FindControl("InsertButton") as LinkButton;

       LinkButton UpdateButton = FormView1.FindControl("UpdateButton") as LinkButton;

       InsertButton.Visible = true;

       UpdateButton.Visible = false;

  }

}
