header in datagrid,gridview help

What I might recommend is a dynamically populated set of repeater objects instead of a datagrid.

Basically you set the "fields" of your repeater (labels, text areas, whichever) along with styles and colours of choice and you populate the repeater from your data.

In that way you can have 2x repeaters, one for the primary discussion/original post and one for replies which is a subset of the first one.

When populating the first repeater it populates based on the primary discussion and if the primary discussion has replies you populate the secondary repeater with those.

Unfortunately, it's a bit beyond what I've done with repeaters myself so I can't give detailed code as I've only worked on single-level repeaters myself but I'm sure it can be done :twisted: and it would allow you much more flexibility on formatting and such than the datagrid method.

A good resource for how to use the repeater can be found here.

Hope this helps :)

Edit: I would approach it something like this:

<asp:Repeater ID="Repeater1" runat="server">
            --Repeater format setup--
            <asp:Repeater ID="repeater2" runat="server">
                --Repeater format setup--
            </asp:Repeater>
        </asp:Repeater>

Technically, if configured correctly with the 2nd repeater INSIDE the first repeater (which I guess is the tricky part) and the correct data population you should be able to get the effect you're needing with what I supplied.

Basically repeater1 should be configured as a straight up select of all the "questions", repeater2 should be configured to select all answers based on the current question. In that way it SHOULD give your required result.

By configuring as indicated abouve you should get the following:
Repeater1 details
Repeater2 details
Repeater1 details2
Repeater2 details2
Repeater2 details2, 2nd
Repeater2 details2, 3rd
Repeater1 details3
Repeater2 details3

And so on... I'd play around with dynamic population of the dataset for repeater2 based on the current information from repeater1 to achieve this result.

I take it back... after fiddling and playing with the controls I can't get it to do what you want :twisted: The main reason being that the databinding is not controlled enough for me to get a variable into the 2nd repeater representing the message id of the first repeater so it can selectively populate a list of responses related to that item.

Sorry, really thought it would work and if you can find a way to populate the repeaters at the code-behind level instead of the front end data-bind level it would work :)

Thank you sir for Replaying I got the soltion here is my code for that i think this will help other also.
as per you firsttold i had created neasted Repeater and then on form load i'ed written this code for that

protected page_load
dim da as new sqlDataAdpter("Select* from [table1];Select* from [Table2]",con)
dim ds as new dataset
da.fill(ds)
ds.Relations.Add("name",ds.Tables(0).Columns("ID"),ds.Tables(1).Columns("ID"))
 Repeater1.DataSource = ds
 Repeater1.DataBind()
end sub

Protected Sub Repeater1_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.RepeaterItemEventArgs) Handles Repeater2.ItemDataBound
        Dim dv As DataRowView = TryCast(e.Item.DataItem, DataRowView)
        If dv IsNot Nothing Then
            Dim rpt As Repeater = TryCast(e.Item.FindControl("childrpt"), Repeater)
            If rpt IsNot Nothing Then
                rpt.DataSource = dv.CreateChildView("name")
                rpt.DataBind()
            End If

        End If
    End Sub

and it works.
