Convert the boundfield Size to a template field, and then edit the template.  Add a dropdownlist and either add the other sizes manually, or bind it to a datasource that contains the additional sizes.

Hello,
my question is how to bind the dropdownlist to the stored procedure to the sizes of the items are that being returned by the stored procedure when a user searches. ( all the sizes are stored in the database and they are different from one item to another ) so i dont think i can add them manually.
i hope i am clear in explaining my problem. i do know how to convert the bound field to a template field and add a ddl.
Thanks i appreciate it.
Ok, so each dropdownlist will have different values?

I'm thinking the best way to do that would be to convert it to a template, then add code to the RowDataBound function.  Something like this:
Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound
   If e.Row.RowType = DataControlRowType.DataRow Then
      Dim ddl As DropDownList = e.Row.FindControl("DropDownList1")
      'add some code to get data from Stored Procedure
      '
      For Each item In DataRows
         Dim li As New ListItem(item)
         ddl.Items.Add(li)
      Next
   End If
End Sub

Can u show how the data is being fetched from the stored procedure.

How are you planning to return all the sizes for the record?
Hello All,
i just did it by creating a separate stored procedure which would get me just the item number and sizes and used this as the data source for the DDL.
Thanks guys i appreciate your help.
