Insert Data Code with
Return Boolean and Int Result
Step by Step:
1. Create Property Class for This Section and create members
as inserted data required.
2. Set Property to appropriate data taken by Control.
3. After taking data in property class just call Logic layer
Class with this Property Class’s obj .
4. For Step 3 just create Logic Layer Class and create
method which take Property Class’s obj and call DataLayer’s Mehod with Property Class’s
obj as a parameter.
5. For Step 4 just create DataLayer Class with method which
take Property Class’s obj and by this obj create SqlParameter[] and set
SqlParameter with the help of Properties Value.
6. After that call the method of Main Data Class, this class
is vary on Company by Company.
7. This Main Data Class takes two parameter (a).Procedure
Name (b). Sqlparameter[]
8. Return Type of All Methods will be same as return type of
Main Data Class.

On Submit Button:::
protected void
btnSubmit_Click(object sender, ImageClickEventArgs e)
{
/*******************************Insertion***************************************/
try
{
if (!Page.IsValid)
return;
objProp.EventDate = Convert.ToDateTime(txtEventDate.Text);
objProp.ClientID
= Convert.ToInt32(Session["clientId"]);

bool IsDone=objEvent.AddEvent
(objProp );
if (IsDone)
Response.Redirect("message.aspx?EventIsOpen=true&id=72");

//Logic Class (ClsEvent)
public bool
AddEvent(ClsEventProp objProp)
{
ClsEventDB objDB = new ClsEventDB();
//Data Class
bool IsDone;
IsDone = objDB.AddEvent(objProp);
return IsDone;
}
//Data Class (ClsEventDB)
internal bool AddEvent(ClsEventProp
objProp)
{
SqlParameter[] param ={
new SqlParameter
("@EventDate",objProp .EventDate
),
new SqlParameter
("@ClientId",objProp .ClientID )
};
//Call Main Data Layer Class Method.
return ClsDataLayer.GetScaler("sp_Add_Event", param);
}
Main Data Class’ Method.
(Always create mehod as Static)
1…[Mehod which return int Value for get value which return by
Stored procedure]
public static int
InsertUpdate(String p, SqlParameter[] param)
{
int id;
SqlConnection
conn = GetConnection();
SqlCommand
cmd = new SqlCommand(p, conn);
try
{
cmd.CommandType = CommandType.StoredProcedure;
cmd.CommandTimeout = 0;
conn.Open();
SqlParameter
returnvalue = new SqlParameter("returnvalue",
SqlDbType.Int);
returnvalue.Direction = ParameterDirection.ReturnValue;
cmd.Parameters.Add(returnvalue);
foreach (SqlParameter
para in param)
{
cmd.Parameters.Add(para);
}
cmd.ExecuteNonQuery();
id = Convert.ToInt32(returnvalue.Value);
return id;
}
catch (Exception
ex)
{
throw ex;
}
finally
{
cmd.Dispose();
conn.Close();
}
}
2…[Mehod which return Bool Value for inspect operaton success or
not.]
