C#-WEB: Selected Value in User Control

[Eleven]

Hi everybody!

I've got a User Control "SelectBatchByTerminal", that has two dropdown lists, "TerminalDropDownList" and "BatchDropDownList".

using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
 
public partial class UserControls_SelectBatchByTerminal : System.Web.UI.UserControl
{
    public delegate void BatchChangedDelegate(Int32 Batch);
    public event BatchChangedDelegate OnBatchChanged;
 
    public Int32 Batch
    {
        get
        {
            if (BatchDropDownList.Items.Count == 0)
                return 0;
 
            if (BatchDropDownList.SelectedValue == null)
                return 0;
 
            if (BatchDropDownList.SelectedIndex == 0)
                return 0;
 
            return Convert.ToInt32(BatchDropDownList.SelectedValue);
        }
    }
 
    public string SelectedTerminalID
    {
        get
        {
            if ((TerminalDropDownList.Items.Count == 0) || (TerminalDropDownList.SelectedIndex == 0))
                return "";
 
            return TerminalDropDownList.SelectedValue;
        }
    }
 
    public string SelectedBatch
    {
        get
        {
            if ((BatchDropDownList.Items.Count == 0) || (BatchDropDownList.SelectedIndex == 0))
                return "";
 
            return BatchDropDownList.SelectedValue;
        }
    }
 
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
            BindTerminals();
    }
 
    protected void BindTerminals()
    {
        Trace.Write("Binding Data");
        TerminalDropDownList.DataTextField = DAL.CashTrack.Terminals.Columns.TerminalId;
        TerminalDropDownList.DataValueField = DAL.CashTrack.Terminals.Columns.TerminalId;
        //Line below to be re-written to use SelectedTerminalId instead of LoggedInUser
        TerminalDropDownList.DataSource = DAL.CashTrack.Sprocs.SpGetTerminalForBatch(Global.LoggedInUser.FkBanksID.Value).GetDataSet();
        TerminalDropDownList.DataBind();
        TerminalDropDownList.Items.Insert(0, new ListItem(">> Select <<", "0"));
        TerminalDropDownList.SelectedIndex = 0;
    }
 
    protected void BindBatches(string terminal)
    {
        BatchDropDownList.DataTextField = DAL.CashTrack.Deposits.Columns.Batch;
        BatchDropDownList.DataValueField = DAL.CashTrack.Deposits.Columns.Batch;
        BatchDropDownList.DataSource = DAL.CashTrack.Sprocs.SpGetBatchByTerminal(terminal).GetDataSet();
        BatchDropDownList.DataBind();
        BatchDropDownList.Items.Insert(0, new ListItem(">> Select <<", "0"));
        BatchDropDownList.SelectedIndex = 0;
    }
 
    protected void TerminalDropDownList_SelectedIndexChanged(object sender, EventArgs e)
    {
        BindBatches(TerminalDropDownList.SelectedValue);
    }
 
    protected void BatchDropDownList_SelectedIndexChanged(object sender, EventArgs e)
    {
        if (this.Batch != 0)
        {
            if (OnBatchChanged != null)
                OnBatchChanged(this.Batch);
        }
    }
}
 

And I've got a page "DepositPerBatch" that uses that UC..

using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
 
public partial class Deposits_DepositPerBatch : System.Web.UI.Page
{
    protected override void OnInit(EventArgs e)
    {
        base.OnInit(e);
 
        wiz.ActiveStepIndex = 0;
        SelectBatchByTerminalUC.OnBatchChanged += new UserControls_SelectBatchByTerminal.BatchChangedDelegate(OnBatchChanged);
    }
 
    protected void Page_Load(object sender, EventArgs e)
    {
 
    }
 
    protected void OnBatchChanged(Int32 Batch)
    {
 
    }
 
    protected void wiz_NextButtonClick(object sender, WizardNavigationEventArgs e)
    {
        try
        {
            if (SelectBatchByTerminalUC.Batch == 0)
                throw new Exception("Please select a Batch Number to continue");
 
            // Now we can query the data for the deposit
            DAL.CashTrack.VwDepositsByBatchCollection deposit = new DAL.CashTrack.VwDepositsByBatchCollection().Where(DAL.CashTrack.VwDepositsByBatch.Columns.Batch, SelectBatchByTerminalUC.Batch).OrderByDesc(DAL.CashTrack.VwDeposits.Columns.AccountNumber).Load();
            if (deposit.Count == 0)
                throw new Exception("Sorry... We are unable to locate any deposits for the selected batch");
 
            BatchNumberLabel.Text = Convert.ToString(deposit[0].Batch);
            TerminalLabel.Text = "TBD"; //deposit[0].TerminalId;
 
            Grid1.DataSource = DAL.CashTrack.VwDepositsByBatch.FetchByParameter(DAL.CashTrack.VwDepositsByBatch.Columns.Batch, SelectBatchByTerminalUC.Batch, SubSonic.OrderBy.Asc(DAL.CashTrack.VwDepositsByBatch.Columns.DateX));
            Grid1.DataBind();
        }
        catch (Exception ex)
        {
            e.Cancel = true;
            Savitar.Web.Utils.Popup.ShowDialog(this, ex.Message);
        }
    }
}
 

The page works but it displays all the terminals, I want to change the following line to use the terminal selected in the user control, instead of the LoggedInUser

TerminalDropDownList.DataSource = DAL.CashTrack.Sprocs.SpGetTerminalForBatch(Global.LoggedInUser.FkBanksID.Value).GetDataSet();
 

I know I have to change my Stored Procedure as well, which currently looks like this:

ALTER PROCEDURE [dbo].[spGetTerminalForBatch]
(
  @BankID INT
)
AS
 
SELECT DISTINCT TerminalId
FROM vwDepositsByBatch
WHERE fkbankId = @BankID AND TerminalID <> '0'
ORDER BY TerminalId
 

The TerminalId is a string!

Any help would be appreaciated, let me know if you don't understand what I wrote, i'll try and explain it a bit more.

ALTER PROCEDURE [dbo].[spGetTerminalForBatch]
(
  @Terminal VARCHAR(8)
)
AS
 
 
SELECT DISTINCT TerminalId
FROM vwDepositsByBatch
WHERE TerminalId = @Terminal
ORDER BY TerminalId
 

I wrote a new SP but I'm not really sure what to edit on my C# code
