Answer 1

I just had to do the same exact type of thing…here is how you add a column.

If Not IsPostBack Then <br>

        Dim field As New TemplateField
        field.HeaderText = "Name of Column"
        Dim col As DataControlField = field
        GridView.Columns.Add(col)

        End If

**In the Gridview_rowcreated Sub

e.row.cells(cellnumber from 0 to N).controls.Add(data)

you’re going to have to create a connection and a connection string

here is an example…

Dim Dbconn As SqlConnection
Dim Dbcmd As SqlCommand

Dbcmd = New Data.SqlClient.SqlCommand()
Dbcmd.Connection = Dbconn
Dbcmd.CommandType = Data.CommandType.Text

Dbcmd.Commandtext = "select * from table"
dbconn.open()

//then you need a data reader

dim dr as sqlclient.sqldatareader
dr = dbcmd.executereader
while dr.read
add each item to a list
end while

then on page load set your datasource of the grid to the list

hope this helps…if you have any questions just ask me.
