I want to add labels through loop
`private void CourseOutcomes_Load(object sender, EventArgs e)
{
studentDetails dets = new studentDetails();
dets.ShowDialog();
name=dets.CourseName;
labelCourseName.Text = name;
string id = dets.CourseValue;
SqlDataReader sdr = bznessLogic.GetQuestions(id);
List<Label> lbl = new List<Label>();
int count = 0;
while (sdr.Read())
{
MessageBox.Show("s");
lbl[count] = new Label();
lbl[count].Text = sdr[0].ToString();
this.Controls.Add(lbl[count]);
count++;
}
sdr.Close();
}`
But it keeps giving error
'Index was out of range.
Should I initiablize it diffrently or..
So it turns out I just needed to initialize it properly which I expected, noob mistake but here we are.
private void CourseOutcomes_Load(object sender, EventArgs e)
{
studentDetails dets = new studentDetails();
dets.ShowDialog();
name=dets.CourseName;
labelCourseName.Text = name;
string id = dets.CourseValue;
SqlDataReader sdr = bznessLogic.GetQuestions(id);
List<Label> lbl = new List<Label>();
int count = 0;
while (sdr.Read())
{
MessageBox.Show("s");
lbl.Add(new Label() { Name="lbl"+count});
lbl[count].Text = sdr[0].ToString();
this.Controls.Add(lbl[count]);
count++;
}
sdr.Close();
}

I need help here. Below is my code. In this line of code
dtCurrentTable.Rows[0]["Kolicina"] = Convert.ToInt32(Label37.Text) + 3;
instead of 3 in next method this Label37.Text value should be incremented for one each time when user press the button.So I want this label value in next method to start to count from current value for one each time on button click.
protected void btnTest_Click(object sender, EventArgs e)
{
var clickedRow = ((Button)sender).NamingContainer as GridViewRow;
var clickedIndex = clickedRow.RowIndex;
decimal old = dtCurrentTable.Rows[clickedIndex].Field<decimal>("Kolicina");
decimal oldIznos = dtCurrentTable.Rows[clickedIndex].Field<decimal>("VkIznos");
decimal VkDanok = dtCurrentTable.Rows[clickedIndex].Field<decimal>("VkDanok");
string Cena1 = dtCurrentTable.Rows[clickedIndex].Field<string>("Cena1");
int TarifaID = dtCurrentTable.Rows[clickedIndex].Field<Int16>("TarifaID");
newValue = old - 1;
// so i need label value from here to go in next method and increment++
Label37.Text = newValue.ToString();
decimal newIznos = oldIznos - Convert.ToDecimal(Cena1);
dtCurrentTable.Rows[clickedIndex].SetField("Kolicina", newValue.ToString());
dtCurrentTable.Rows[clickedIndex].SetField("VkIznos", newIznos.ToString());
}
protected void Button6_Click(object sender, EventArgs e)
{
SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["string2"].ConnectionString);
conn.Open();
ViewState["count"] = Convert.ToInt32(ViewState["count"]) + 1;
// SqlCommand sqlCmd = new SqlCommand();
// sqlCmd.CommandText = "SupaSpanak";
// sqlCmd.Connection = conn;
// sqlCmd.CommandType = CommandType.StoredProcedure;
SqlCommand cmd1 = new SqlCommand("SELECT pkid,Artikal,Vid,EdMera,TarifaID,Cena1 FROM Artikli WHERE Artikal= 'N KREM SUPA OD SPANA]++' AND Cena1 = 130.00", conn);
//brojac za kolicina
count++;
decimal noofcount = count;
Session["kolicina"] = noofcount;
Label5.Text = Session["kolicina"].ToString();//ViewState["count"].ToString();//
SqlDataReader reader = cmd1.ExecuteReader();
if (reader.Read())
{
Label9.Text = (string)reader["pkid"].ToString();
Label3.Text = (string)reader["Artikal"].ToString();
Label23.Text = (string)reader["Vid"].ToString();
Label10.Text = (string)reader["EdMera"].ToString();
Label7.Text = (string)reader["TarifaID"].ToString();
Label4.Text = (string)reader["Cena1"].ToString();
decimal cena = Convert.ToDecimal(Label5.Text);//kolicina
decimal kolicina = Convert.ToDecimal(Label4.Text);//cena
//vkIznos
decimal mnoz = cena * kolicina;
Label6.Text = mnoz.ToString();
Convert.ToDecimal(Label6.Text);
conn.Close();
DataTable dtCurrentTable = (DataTable)ViewState["Markici"];
if (Label37.Text == "0")
{
dtCurrentTable.Rows[0]["Kolicina"] = Label5.Text;
}
if (Label37.Text != "0")
{
//Here this current value of Label37.text need to be incremented for one each time when button is clicked.
dtCurrentTable.Rows[0]["Kolicina"] = Convert.ToInt32(Label37.Text) + 3;
}
you need viewstate,
public int Counter
{
get
{
if (ViewState["Counter"] != null)
{
return Convert.ToInt32(ViewState["Counter"]);
}
else
return 0;
}
set { ViewState["Counter"] = value; }
}
protected void Button6_Click(object sender, EventArgs e)
{
//other codes..
Counter = Counter + 1;
if (Label37.Text != "0")
{
dtCurrentTable.Rows[0]["Kolicina"] = Convert.ToInt32(Label37.Text) + Counter;
}
}
I have a web form that uses a text box to update a comments field in the database. I would like to check for a blank before update and have a reminder box that says "Comment section blank, continue?", then have a yes / no option. This would allow the user to return to the update without making changes. The text box is visible when the user selects edit on the row in a gridview. I will provide code below so that anyone can see what I am doing. If this cannot be done this way, simply a message box saying that the comment section is blank would suffice.

You show only server side code, and it's more complicated doing chek on server side and show message on client.
Simple sample of chek on client side by javascript:
<script type="text/javascript">
function MyConfirm() {
if (document.getElementById("tb1").value == '')
if (confirm("Comment section blank, continue?"))
return true;
else
return false;
else true;
}
</script>
<asp:TextBox runat="server" ID="tb1" />
<asp:Button runat="server" ID="btn1" onclick="btn1_Click" OnClientClick="return MyConfirm();" Text="Save" />

I have a method that reads data from a database table using SqlDataReader.
i assign data retrieved by SqlDataReader into a List and return it.
when i want to assign the List data from method into the List on Code behind file,
i encounter the following error:
and here is my code
public List<string> displayCustoemrhShipOrder()

SqlCmd.Connection = SqlCOn;
SqlCmd.CommandText = "displayCustomerShipOrder";

SqlCOn.Open();
SqlCmd.Parameters.AddWithValue("ShipOrderID",shipOrderID);
SqlDataReader reader = SqlCmd.ExecuteReader();
while (reader.Read())
{
drList.Insert(i, reader.GetValue(i).ToString());
i++;
}
//reader.Close();
//sqlCon.Close();
reader.Dispose();
SqlCOn.Dispose();
return (drList);
}

I have a user control inside a webpart inside sharepoint that I add some linkbuttons dynamically during runtime. each one when clicked is supposed to download a certain file from the database. however when one of those linkbuttons is clicked, this file is downloaded for once and then i can't click any other buttons or links or even the same one again on this user control and webpart. but i can still click other things outside the user control and webpart. do u have any idea? please tell me which part of the code i can add here if you need to check something. thank you :)

the weird thing that it works well when i put the same code in an asp.net page!!
Ahmad,
Check out the following link on the MSDN forums, as I believe the situation is similar (if not identical) to what you're describing:
http://social.msdn.microsoft.com/forums/en-US/sharepointdevelopment/thread/107b2c17-07fe-4a15-ad81-dcb31e1e9c84/
A couple of different approaches/solutions are discusssed.
I hope this helps!
