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; [code]....
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 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?

I have a GridView that has several dynamic columns (I do not know how many at design time and it could be 0-12 columns, hence need for dynamic columns). I have the columns in the grid and data bound to them - works great. There are other standard, design-time TemplateField columns with TextBox controls in them. These are bound with values that the user can edit. The grid is posted back via a Submit button. My question is "Why does gv.Columns.Insert() cause all my TextBox data to be null on Postback, but gv.Columns.Add() works like a champ?"
protected void BuildColumns()
{
// The first column to begin to insert the columns in the GridView
int columnIndex = 5;
BoundField aoColumn = new BoundField();
aoColumn.HeaderText = "New Column 1";
gvMyGrid.Columns.Insert(columnIndex, aoColumn); // kills txtQuantity.Text on postback
gvMyGrid.Columns.Add(aoColumn); // works fine
columnIndex++;
foreach (MyEntity my in _myEntityCollection)
{
BoundField myColumn = new BoundField();
myColumn.HeaderText = String.Format("{0:d}", my.StartDate);
gvMyGrid.Columns.Insert(columnIndex, myColumn);
columnIndex++;
}
}
I then go on to assign values to these BoundFields in the _RowDataBound method and all of this works great. However, when I post back and try to reference some TextBox and they are all null. And yes, I have the BuildColumns() call wrapped in if (!IsPostBack) on Page_Load. Of course I would like to use .Insert() so that the columns can go in the proper location and not at the end of the Columns array.

GridView1.Columns.Count is always zero even SqlDataSource1.DataBind();
But Grid is ok I can do
for (int i = 0; i < GridView1.HeaderRow.Cells.Count;i++)
I rename request headers here but
GridView1.Columns[i].Visible = false;
I can't use it because of GridView1.Columns.Count is 0. So how can I hide them ?

I have a datasource, which includes many columns, idealy, I need use a gridview to show:
1) first 3 columns: template fields, these fields depends on values in some columns of datasource. I use template fields, hard coded. works fine.
2) the other columns. This is I do not know how to do it. In the data source, there are about 10-20 columns data, each time, the # of columns of the data varies. idealy, I need show each of them as a seperated column in gridview. The entire data source may have 30 columns, but some of them are used in 1), and I only want show these 10-20 columns in gridview. Some columns in data source, I may not use them at all. is there a way to do this? or have to seperate them as a detail view style UI?

I apologize for the odd title. I've been trying to figure out how to do this and can't quite put it into words. Basically, I need to try to display a GridView with a whole bunch of columns (37 in one case) in two "rows" of columns. More or less.
So instead of this:
Column1 Column2 Column3 Column4 Column5 Column6
Data Data Data Data Data Data
Data Data Data Data Data Data
Data Data Data Data Data Data
I'd like something like this:
Column1 Column2 Column3
Data Data Data
Data Data Data
Data Data Data
Column4 Column5 Column6
Data Data Data
Data Data Data
Data Data Data
As in the example there can be multiple rows returned which all need to be displayed. I'm trying to stop a very large horizontal scroll bar being required. I've been searching as much as I can but haven't found anything that fits what I'm looking for.

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:
