thanks for the reply leppie, unfortunatly javascript wont do it either. This needs to be server side because the values I get from the id of the checked checkbox will be used to gather the data on the next page.
I guess to ask it a different way: Can I get the correct value of a checkbox without posting back? What needs to change in the code above in order for this to happen? I can't set the AutoPostBack to true because of the refresh. This event I created takes the refresh away but now I cannot grab the value with the current code.
Come to think of it, I might just forget about doing it the event way and just do all validation in the Continue buttons click event...not sure what client would say but I know it works.
Thanks again leppie for the time.

If you want a textbox without a cursor, you have to make it non-editable. That you do by disabling the textbox.
If you want to draw on top of a control, you have to do that in the paint event, or whatever you draw will be drawn over whenever the control is updated.

Hey again :P
So I have a XML with DataSet in it, in the DataSet I have 2 DataTables, in each DataTable I have a Uniqe ID, and I did to this row, auto-inc, and don't allow DBNull.
So when I try to do NewRow(), and add it without setting the ID column, it throws an Exception DataColumn 'ID' can't allow DBNull.
So how can I do it as UNIQE ID? do I need to allow DBNull?

Hi,
i am using tableadapters to insert into 2 different tables the insert methods are in transaction. The first insert must return a value for the second insert. both inserts works just fine if the execution mode of the first tableadapter is nonquery(it doesn't return the @@IDENTITY I need) and if i remove the neccessary forein key in the second table but when i change it to scalar(to get the @@IDENTITY neccessary) it returns the following error. "ExecuteScalar requires the command to have a transaction when the connection assigned to the command is in a pending local transaction. The Transaction property of the command has not been initialized.". can anyone please help.

Hello.
I can't find a control to check a Regular Expression that I want... so I could check a TextBox.
How can I do it? (or what is the Control for that)
|
|
|
|
|
The control is the RegularExpressionValidator control.

b { font-weight: normal; }

I couldn't find it in the toolbox so I searched it in the "choose items".
When I did OK, it didn't show it in the toolbox, and then I did "Show all items", so it shows it, but I can't drag it or do something with it, it looks like it's disabled...
Maybe you know what can I do?
|
|
|
|

Just to make sure: Is it a web application you are working with?
---
b { font-weight: normal; }

No, it's a win application, that's why I'm posting here and not in ASP.NET forum.
but the other guy helped me.

That explains it. There is no built-in validation controls for windows forms.

Hello,
I've got a table orders with 3 fields:
- date
- productid
- amount
productid & amount are values seperated by commas, f.e.: productid = 1,2 amount = 3,4 (which means there are 3 products "1" and 4 products "2").
Now, I want to select a field by date and get the value of productid & amount and put them in an array (or arraylist?).
Than, I want to fill a datagridview with again 2 colums (amount & productid) with that data.
So for the example the datagridview should look like:
3 1
4 2
This is what I wrote:
<br />
bill.Rows.Clear();<br />
SqlCommand myCommand = new SqlCommand("SELECT * FROM orders WHERE date = @date", connect);<br />
myCommand.Parameters.AddWithValue("@date", DateTime.Parse(listOrders.Text.ToString().Substring(0, 19)));<br />
SqlDataReader myReader = myCommand.ExecuteReader();<br />
while (myReader.Read())<br />
{<br />
amounts = myReader["amount"].ToString();<br />
products = myReader["productid"].ToString();<br />
}<br />
myReader.Close();<br />
<br />
string[] product = new string[products.Split(' ').Length];<br />
string[] amount = new string[amounts.Split(' ').Length];<br />
<br />
product = products.Split(' ');<br />
amount = amounts.Split(' ');<br />
<br />
for (int i = 0; i <= product.Length; i++)<br />
{<br />
bill.Rows.Add(amount[i], product[i], 1, 2);<br />
}<br />
But I always get an error near the product = products.Split ..
System.NullReferenceException was unhandled<br />
Message="Object reference not set to an instance of an object."
I don't really think the code is 100% ok, but can somebody help?
Thanks!

I've annotated your code with what it is doing.
bill.Rows.Clear();
SqlCommand myCommand = new SqlCommand("SELECT * FROM orders WHERE date = @date", connect);
myCommand.Parameters.AddWithValue("@date", DateTime.Parse(listOrders.Text.ToString().Substring(0, 19)));
SqlDataReader myReader = myCommand.ExecuteReader();
while (myReader.Read())
{
amounts = myReader["amount"].ToString();
products = myReader["productid"].ToString();
}
myReader.Close();
string[] product = new string[products.Split(' ').Length];
string[] amount = new string[amounts.Split(' ').Length];
product = products.Split(' ');
amount = amounts.Split(' ');
for (int i = 0; i <= product.Length; i++)
{
bill.Rows.Add(amount[i], product[i], 1, 2);
}
Does this help you see what your code is doing?

I have problem with the data.
From my main window I click other form is opened and I want to type in some data like alarm time, but I have problem with display it in my main window.
I want display it in my label but i don't how to get to that label,and other variables in my main window from my second form??
-- modified at 9:55 Saturday 27th May, 2006
examle I have somethin like this
public partial class Form1 : Form
{
public int a, b, c;
public Form1()
{
InitializeComponent();
}
and I want to acces the a,b,c prameters from my form2.

Ok so what you would do is hand these variables to the constructor of your second form:
Ex.
public partial class Form2 : Form
{
public int d, e, f;
public Form2(int a, int b, int c)
{
d = a;
e = b;
f = c;
InitializeComponent();
}
...
public partial class Form1 : Form
{
public int a, b, c;
public Form1()
{
InitializeComponent();
}
something_OnClick()
{
Form2 frm2 = new Form2(a, b, c);
frm2.ShowDialog();
}
