Hello

Can any one tell me how to use Dynamic Populate Extender.

Is possible try to send me one sample code for populating a dropdownbox on clicking a button.

Waiting for reply. 

Hi Kishore.......

If u want to populate Drop Down Dynamically

First U need to write the Stored Procedure In Data Base and

second thing U need to write the Populate method in Presentation Layer and

3rd is u need to write code in DataAccess Layer to data from DataBase 

 code for Presentation Layer is

private void PopulateDropDown()
    {
            //daStdent is DataAccessLayer Name and next daStdent is DataAccess class name

           daStudent.daStudent objUser = new daStudent.daStudent();

  //GetStudentListInfo is stored procedure

        DataTable dtStudentList = objUser.GetStudentListInfo(connectionString);

        int nTotalRecords = dtStudentList.Rows.Count;
       
        for (int i = 0; i < nTotalRecords; i++)
        {

   //GVDDL is drop down box name
           GVDDL.Items.Add(dtStudentList.Rows[i]["LastName"].ToString());
        }

   }

code for DataAccessLayer

        public DataTable GetStudentListInfo(string ConnectionString)
        {
            //int LastName
            // Set up parameters in parameter array
            SqlParameter[] arParms = new SqlParameter[1];


            //arParms[0] = new SqlParameter("@LastName", SqlDbType.NVarChar);
            // arParms[0].Value = LastName;

            pTransactionSuccessful = true;

            DataTable dtStudentList = new DataTable("StudentList");

            try
            {
                DataSet dsStudentList = SqlHelper.ExecuteDataset(ConnectionString, CommandType.StoredProcedure, "GetStudentListInfo", arParms);
                dtStudentList = dsStudentList.Tables[0];
            }
            catch (SqlException ReadError)
            {
                pErrorMessage = ReadError.Message.ToString();
                pErrorNumber = ReadError.Number;
                pErrorClass = ReadError.Class;
                pErrorState = ReadError.State;
                pErrorLineNumber = ReadError.LineNumber;

                pTransactionSuccessful = false;
            }
            return dtStudentList;
        }
 

 If u still unable to do give me a reply with the error.........
