I have a stored procedure that accepts 3 param (userid,fromdate,todate) from table "JobCard"

and it displays 3 columns from this table(Ticket#,Description,Duration).

i want to call it from c#.net and pass these 3 params and fill the result dataset in a datagrid

CREATE PROCEDURE spGetJobCardDetails
    @UserId INT,
    @FromDate DATETIME,
    @ToDate DATETIME
AS
BEGIN

      SELECT [Ticket#], [Description], [Duration]
           FROM JobCard
           WHERE [UserId] = @UserId
               AND [Date] BETWEEN @FromDate AND @ToDate

END

Hi Moizsaif123;

Something like the following code snippet should produce the wanted results

// Set up the parameters to be passed into the stored procedure
int userId = 222;
DateTime from = DataTime.Parse("1/3/2014");
DateTime to = DataTime.Parse("2/4/2014");

// Create the connection string to connect to the database
string connStr = @"Your ConnectionString goes here";
// Create a connection to the database
using(SqlConnection conn = new SqlConnection(connStr))
{
	  // Create the command to execute on the server
    SqlCommand cmd = conn.CreateCommand();
    // The stored procedure to be called
    cmd.CommandText = "[dbo].[spGetJobCardDetails]";
    // Initialize the parameters to be sent
    cmd.CommandType = CommandType.StoredProcedure;
    cmd.Parameters.Add("@UserId", SqlDbType.Int);
    cmd.Parameters["@UserId"].Value = userId;
    cmd.Parameters.Add("@FromDate", SqlDbType.DateTime2);
    cmd.Parameters["@FromDate"].Value = from;
    cmd.Parameters.Add("@ToDate", SqlDbType.DateTime2);
    cmd.Parameters["@ToDate"].Value = to;
    // Initialize the DataTable that will hold the data
    DataTable dt = new DataTable();
    // Create the data adapter that communicates with SQL server
    SqlDataAdapter da = new SqlDataAdapter(cmd);
    // Fill the data table
    da.Fill(dt);
    // Assign the data table to the data grid
    dataGridView1.DataSource = dt;
}

I have posted code below for pulling data from stored proc into a dataset into grid.

The grid is not appearing and page is running without error. How can i check if the dataset is empty or not or if the grid property do i need to set any field for this.


SqlCommand com = new SqlCommand();
            com.Connection = DB.Connection;
            com.CommandType = CommandType.StoredProcedure;
            com.CommandText = "TestProc";
            com.Connection.Open();

            SqlParameter UserID = new SqlParameter("@UserId", Session["UID"].ToString());
            UserID.DbType = DbType.String;
            com.Parameters.Add(UserID);

            //parameter 2-Ticket Date
            SqlParameter FromDate1 = new SqlParameter("@FromDate", DateTime.Now.ToString());
            FromDate1.DbType = DbType.DateTime;
            com.Parameters.Add(FromDate1);

            //parameter 3-Ticket Time
            SqlParameter ToDate1 = new SqlParameter("@ToDate", DateTime.Now.ToString());
            ToDate1.DbType = DbType.DateTime;
            com.Parameters.Add(ToDate1);
            com.ExecuteNonQuery();
            //DataTable dt = new DataTable();
            DataSet ds = new DataSet();
            // Create the data adapter that communicates with SQL server
            SqlDataAdapter da = new SqlDataAdapter(com);
            // Fill the data table
            da.Fill(ds);
            // Assign the data table to the data grid
            GridView2.DataSource = ds;
            GridView2.DataBind();
            com.Connection.Close();

Hi Moizsaif123;

Please see the two parts of the code surrounded with //========= and //========= for needed changes.

SqlCommand com = new SqlCommand();
com.Connection = DB.Connection;
com.CommandType = CommandType.StoredProcedure;
com.CommandText = "TestProc";
com.Connection.Open();

SqlParameter UserID = new SqlParameter("@UserId", Session["UID"].ToString());
UserID.DbType = DbType.String;
com.Parameters.Add(UserID);

//parameter 2-Ticket Date
SqlParameter FromDate1 = new SqlParameter("@FromDate", DateTime.Now.ToString());
FromDate1.DbType = DbType.DateTime;
com.Parameters.Add(FromDate1);

//parameter 3-Ticket Time
SqlParameter ToDate1 = new SqlParameter("@ToDate", DateTime.Now.ToString());
ToDate1.DbType = DbType.DateTime;
com.Parameters.Add(ToDate1);

// =====================================================================
// This should not be in the code. The SqlDataAdapter will be executing
// the Command on the server. 
// com.ExecuteNonQuery();
// =====================================================================

//DataTable dt = new DataTable();
DataSet ds = new DataSet();
// Create the data adapter that communicates with SQL server
SqlDataAdapter da = new SqlDataAdapter(com);
// Fill the data table
da.Fill(ds);

// =====================================================================
// The DataSet can hold many DataTable's so you will need to tell it which one
// Assign the data table to the data grid
GridView2.DataSource = ds.Tables[0];
// =====================================================================

GridView2.DataBind();
com.Connection.Close();

Because a Web application is stateless you need to reload the data back in to the DataSet or store the data between invocation so that it is available when the page is reloaded on the Button click.
