OK. A clue, and the only one I'll give. ListView has two properties that begin with Selected read the documentation for them.

I am working in Microsoft Visual Studio 2008 using C#. I populated my webpage from a database which was SQL Server 2005. On the webform that will be displayed to the users, I want to display a textbox when they click the checkbox, and if they don't click the checkbox I don't want the textbox to be displayed. How do I go about this?? Thank you!!

We have an ASP.NET forum.
You would do this with javascript, which means it's more of a general web dev question.

this can be done with javascript
use,
function ChkFunc()
{
var chk = document.getElementById("<%=CheckBox1.ClientID%>");
var txtbox = document.getElementById("<%=TextBox1.ClientID%>");
if (chk.checked) {
txtbox.style.display = "block";
}
else {
txtbox.style.display = "none";
}
return;
}
in code behind,use
CheckBox1.Attributes.Add("onClick", "return ChkFunc();");
to make the textbox invisible on load, cal this javascript function in page load as well
dont use TextBox1.Visible=false in page load,then this script gives error.
Hope it helps u.

What you seem to be doing is different, to say the least. As such I have no answer for you.
Whilst your question is clear and understandable, is there any chance that you can broaden your description to include the aim of the application, or why the user would be typing code into a text box?

In simple words, you cant. Learn how to use regular expression if you really need this type of task.

Of course you can; I have a small program that takes one method from a textbox, compiles and executes it. It is based on CSharpCodeProvider class. It isn't beginner's stuff though.
IIRC there has been a CP article on the subject, several years ago.

There seems to be a problem with my code when I try and retrieve multiple tables. Please tell me what's wrong, or if there is an alternative way to do this? Thanks in advance.
OleDbConnection clsConnection;
clsConnection = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\\one.mdb;");
clsConnection.Open();
WTest1.oneDataSet f_table = new WTest1.oneDataSet();
OleDbDataAdapter dAdapter = new OleDbDataAdapter("SELECT * FROM first", clsConnection);
dAdapter.Fill(f_table, "first");
WTest1.oneDataSet s_table = new WTest1.oneDataSet();
OleDbDataAdapter dAdapter1 = new OleDbDataAdapter("SELECT * FROM second", clsConnection);
dAdapter1.Fill(s_table, "second");

Why are you using typed datasets?
Can you use System.Data.DataSet datasets???

I have a web application where I need to take an object I created and return the value to a list.
For example, one of the samples I was referencing was from a blog app (dotnetblogengine). This code was to return all blog posts created within a specific date range. The code looked like this:
List<post> list = Posts.FindAll(delegate(Post p)
{
return (p.DateCreated.Date >= dateFrom && p.DateCreated.Date <= dateTo);});
}
</post>
I now need to do something similar however I need to take all sales from our sales reps and return their total amount earned into the list. So for example, here's some sample data:
Employee ID | Employee Name | Sales Transaction Amount
---------------------------------------------------
1 | John | 18.47
2 | Beth | 27.67
1 | John | 12.04
1 | John | 10.50
3 | Allen | 34.87
2 | Beth | 19.12
I would then need to return to the list, the following:
Beth: $46.79
John: $41.01
Allen: $34.87
How could I do this using something like the following:
List<sales> list = Sales.FindAll(delegate(Sales s)
{
}
</sales>
Any ideas or where I could look to find some similar samples?
Thanks.

If you are not averse to using LINQ you could do something like
List<product> products = GetProductList();
var categories =
from p in products
group p by p.Category into g
select new { Category = g.Key, TotalUnitsInStock = g.Sum(p => p.UnitsInStock) };
ObjectDumper.Write(categories);
</product>
For context this is pasted directly from the 'Sum - Group' example from MSDN[^].
If you investigate and decide that it is a usable approach, any follow-up questions might be better asked in the 'Linq and .NET 3.5' forum.
Please don't ask me. I've only just started learning LINQ myself.
