Hi i was wondering on how to make my textbox not to display text:In progress when i select a user_id from a combobox named:
cboUser for second time in c# windows forms with sql server 2008?
So i have form named:
frmUsercheckin which has a combobox named:
cboUser(which contains user_ids)
Given below is my
c# code of
frmUsercheckin:
using System.Data.SqlClient;
namespace Mini_Project
{
public partial class frmUsercheckin : Form
{
public frmUsercheckin()
{
InitializeComponent();
string manager = ("Select m.manager_id as manager_id,(m.manager_first_name+' '+m.manager_last_name+'|'+right('000'+convert(varchar,m.manager_id),5)) as Name from ManagerDetail m where m.status=1");
DataTable dt = new DataTable();
SqlConnection conn = new SqlConnection("Data Source=NPD-4\\SQLEXPRESS;Initial Catalog=Task;Integrated Security=true");
if (conn.State != ConnectionState.Open)
{
conn.Open();
}
SqlCommand dcr = new SqlCommand(manager, conn);
dt.Load(dcr.ExecuteReader());
cboManager.DataSource = dt;
cboManager.ValueMember = "manager_id";
cboManager.DisplayMember = "Name";
cboManager.SelectedValue = 0;
this.UserFillList();
}
private void UserFillList()
{
string user = ("Select ('000'+convert(varchar,UserDetail.user_id)) as user_id from UserDetail where UserDetail.user_type=0 and UserDetail.status=1");
DataTable dt = new DataTable();
SqlConnection conn = new SqlConnection("Data Source=NPD-4\\SQLEXPRESS;Initial Catalog=Task;Integrated Security=true");
if (conn.State != ConnectionState.Open)
{
conn.Open();
}
SqlCommand dcr = new SqlCommand(user, conn);
dt.Load(dcr.ExecuteReader());
cboUser.DataSource = dt;
cboUser.ValueMember = "user_id";
cboUser.DisplayMember = "user_id";
cboUser.SelectedValue = 0;
}
private void btnCreate_Click(object sender, EventArgs e)
{
SqlConnection conn = new SqlConnection("Data Source=NPD-4\\SQLEXPRESS;Initial Catalog=Task;Integrated Security=true");
if (conn.State != ConnectionState.Open)
{
conn.Open();
}
SqlCommand cmd = new SqlCommand();
cmd.Connection = conn;
cmd.CommandType = CommandType.Text;
int autoGenId = -1;
cmd = new SqlCommand("Insert into UserCheckIn(user_id,user_name,task_id,check_in_date,check_out_date,manager_id,remarks,stat,row_upd_date)"+"Values(@user_id,@user_name,@task_id,@check_in_date,@check_out_date,@manager_id,@remarks,@stat,GetDate()); Select @autoGenId=SCOPE_IDENTITY();", conn);
cmd.Parameters.AddWithValue("@user_id", cboUser.SelectedValue);
cmd.Parameters.AddWithValue("@user_name", txtUserName.Text);
cmd.Parameters.AddWithValue("@task_id",lstTasks.SelectedValue);
cmd.Parameters.AddWithValue("@check_in_date", dtCheckIn.Value);
cmd.Parameters.AddWithValue("@check_out_date", dtCheckOut.Value);
cmd.Parameters.AddWithValue("@manager_id", cboManager.SelectedValue);
cmd.Parameters.AddWithValue("@remarks", txtRemarks.Text);
cmd.Parameters.AddWithValue("@stat", 1);
cmd.Parameters.Add("@autoGenId", SqlDbType.Int).Direction = ParameterDirection.Output;
cmd.ExecuteNonQuery();
autoGenId = Convert.ToInt32(cmd.Parameters["@autoGenId"].Value);
cmd = new SqlCommand("Update TaskDetail set status=1 where user_id='" + cboUser.SelectedValue + "'", conn);
cmd.Parameters.AddWithValue("@status", 1);
cmd.ExecuteNonQuery();
((MDIParent1)this.MdiParent).updateUserActivities(autoGenId, 5, txtUserName.Text + "User has successfully checked in the task assigned to him");
MessageBox.Show("User has successfully checked in the task assigned", "Task", MessageBoxButtons.OK, MessageBoxIcon.Information);
conn.Close();
this.Close();
}
private void cboUser_SelectionChangeCommitted(object sender, EventArgs e)
{
string DMstr;
DMstr = cboUser.SelectedValue.ToString();
SqlConnection conn = new SqlConnection("Data Source=NPD-4\\SQLEXPRESS;Initial Catalog=Task;Integrated Security=true");
if (conn.State != ConnectionState.Open)
{
conn.Open();
}
string userpull = ("Select UserDetail.user_first_name,UserDetail.user_last_name from UserDetail where UserDetail.user_id="+DMstr);
SqlCommand mdc = new SqlCommand(userpull);
mdc.Connection = conn;
mdc.CommandType = CommandType.Text;
SqlDataReader dax = mdc.ExecuteReader();
while (dax.Read())
{
userpull = dax[0].ToString() + dax[1].ToString();
txtUserName.Text = dax[0].ToString() + " " + dax[1].ToString();
}
dax.Close();
conn.Close();
txtRemarks.Text="In Progress";
}
The above code works OK! Given below is my structure of my table named:
UserCheckIn in sql server 2008.
ColumnName DataType AllowNulls
agn(auto-increment) Int No
user_id Int Yes
user_name nvarchar(70) Yes
task_id Int Yes
check_in_date datetime Yes
check_out_date datetime Yes
manager_id Int Yes
remarks nvarchar(80) Yes
stat bit Yes
row_upd_date datetime Yes
What i want is when i select a
user_id from combobox(
cboUser) and select a
task from listbox(
lstTasks) for the first time then i want my textbox(
txtRemarks) to display/show text:
In Progress upon selection of user_id from
cboUser(combobox) and task from
lstTasks(listbox) for the first time only.
But when i select the same user_id from combobox(
cboUser) and same task from listbox(
lstTasks) for the second time then i want my textbox(
txtRemarks) to not to show any text in
txtRemarks at all upon selection of same user_id from
cboUserstTasks(listbox) for second,third time and so on..
Can anyone help me please! Can anyone tell me what modifications must i do in my above c# code and what modifications must i need to do(add new field to table:UserCheckIn in sql server 2008) to achieve my required result?! Can anyone help me/guide me to solve my problem?! Any help/guidance in solving of this problem would be greatly appreciated!
