Question

This is the code i am using.. I want to pass the dropdown selected item as a input to the stored procedure and execute that.. how could i achieve that?

public class DaysForEvents
{
    public DataSet GetDaysForEvents(//This should be my input to stored procedure (i.e)  dropdownselected value)
    {
        SqlConnection con = new SqlConnection(CommonSettings.GetEventsConnectionString());

        try
        {
            SqlCommand sqlcmd = new SqlCommand("proc_fetch_event_days", con);
            SqlDataAdapter sqlda = new SqlDataAdapter(sqlcmd);
            DataSet ds = new DataSet();
           //DateFilter = 0;
            //StatusFilter = 0;

            sqlcmd.CommandType = CommandType.StoredProcedure;

            sqlcmd.Parameters.AddWithValue("@event_id", Event_id);
            // sqlcmd.Parameters["@UserID"].Value = UserID;


            con.Open();
            sqlda.Fill(ds);
            con.Close();

            return ds;


        }

As I understand, you want this.

//get dropdown selected value and store in a variable 
var eventId = dropdown.SelectedValue; 

//pass this variable in the GetDaysForEvents method to get DataSet.
var dataSet = GetDaysForEvents(eventId);
