Add a textbox and other controls to a gridview: Microsoft, ASP.Net

Add a textbox and other controls to a gridview

All,

I am looking at adding a basket to a web page. I have this working to a basic standard, but now want to add extra functionality to it.

At the moment I have the data held in a session array that i populate on the basket screen in a grid view.

I have populated the gridview with 6 columns . The first 2 are not data assigned by the session variables but is a check box column called remove and a text box column called Tyres required that has a text box in.

The other columns are assigned by code (see snippet)

Basically I have three problems that i do not know how to do.

1. Because I used the designer to add the first 2 columns and code the rest the designer columns appear first in the gridview when i would like them to appear at different stages. How do I write the code to add a column and in that column have a text box and how do i do the same but for a check box?

2. How do I then reference that columns text box or check box? At the moment I loop through each row and use this

Dim tb As TextBox = CType(r.FindControl("TextBox1"), TextBox)

Would this be different?

3. On a different note i would possibly like to make something on the row happen if the check box is ticked. Is there an event that says when a row is changed do something. What would the code be say on the check box being checked i wanted the textbox column for this row only to be disabled, but still in the view?

Thanks for your help.

If Not IsPostBack Then
 
 
            Dim arr As String(,) = cartItems
 
            'Label1.Text = cartItemCount
 
            Dim t As New DataTable("salesOrder")
            t.Columns.Add("Part_Number")
            t.Columns.Add("Tyre_Size")
            t.Columns.Add("Aircraft")
            t.Columns.Add("Main_or_AUX")
 
            ' Loops around - 1 because it is a count not an array position
            For i As Integer = 0 To cartItemCount - 1
                t.Rows.Add(arr(i, 0), arr(i, 1), arr(i, 2), arr(i, 3))
            Next
 
            GridView1.DataSource = t
            GridView1.DataBind()
 
        End If
