I have write this code to create a gridview with 3 columns
DataTable dt = new DataTable();
dt = new DataTable();
dt.Columns.Add("ID", typeof(int)).AutoIncrement = true;
dt.Columns.Add("Name", typeof(string));
dt.Columns.Add("Price(Grouch)/Hectares", typeof(float));
DataColumn[] keys = new DataColumn[2];
keys[0] = dt.Columns["ID"];
dt.PrimaryKey = keys;
dt.Rows.Add("1", "Seaside Location", 1.5);
Session[key] = dt;
return dt;
I would like to add in this code a textbox with the quantity.
When i give the quantity i want in another textbox to have the total.
for example 2*1.5=3
How can i do that?
My huge problem is that i dont know how to take the values of the 3rd column.The value 1.5 in this example.

I would like to multiply the values from two text boxes (txtBox1 should contain an Integer value, txtBox2 should contain a Float value) and place the result in a third text box. My code is below, but it doesn't work. The javascript function is called, otherwise it fails.

I'm at the end of a project and have hit a wall. I'm pretty unfamiliar with VB so this is why I've left this piece of the project for last.
I have a popup window in which I pass some values via QueryString. I want to be able to pull them into my application and do some math on them and then write them out to my aspx page. The problem is I don't know where/how to begin. I've searched around the asp.net boards, but can't seem to find any good starting point.
I'm reading in some dollar amounts, a percentage and an Id that I'll use to pull a payment schedule (number of payments). I'm trying to get at a payment breakdown. I was thinking of writing it Something like this:

I've done a bit of development with C# applications but not much with ASP.Net so if this is a trivial issue. I have a webform that has textboxes for password, phone number and a listbox for a provider. When I load up the webpage, I populate with the textboxes and listbox with selections from my SQL database. This works correctly. Then I allow the user to change data in any of controls. In the event that is triggered by the Save button, the values in the textboxes and listbox are the data values that were populated during the loading of the page, not what the user has typed in.
What am I doing wrong? I've attached my 2 pages of code.
Here is the .aspx

I have a FormView Bound to an SQL data source. In the DATA there are 2 columns that i would like to multiply together and display there rate
<asp:TextBox ID="txtPeople" runat="server" Text='<%# Bind("People") %>'></asp:TextBox><asp:TextBox ID="txtRate" runat="server" Text='<%# Bind("Rate") %>'></asp:TextBox><asp:TextBox ID="txtTotal" runat="server" Text='<%# Bind("Rate * People") %>'></asp:TextBox>
This is just an example above but i believe it shows what i am trying to do, there is no calculated column in the database so i can not bind to that directly, and i can not just add the column to the data as its not in my permissions. So how do "Bind" the value of two columns multiplied together to a third text box?

In FormView (insert) I have a number of textboxes into which number will be inputted. I need all these textboxes to add up and display the total in a Label which I can then insert into the database with all the individual values. I expected this to be a simple thing... Then it appears that the best way to do this is to use javascript, which I have never used! SO this is my attempt which is a combination of things I found on the net, In the head (Clientapp is the name of my form)
<script type="text/javascript" language="javascript">
function Add1(Clientapp) {
var a, b, c;
a = document.Clientapp.BondRepaymentTextBox.Value;
b = document.Clientapp.PropertyRentalTextBox.Value;
c = eval(a) + eval(b);
document.Clientapp.ceTotalTextBox.Value = c;
}
</script>
Code behind on Page Load
PropertyRentalTextBox.Attributes["onchange"] = "javascript: Changed( this );";
