I'm trying display data from a sqldatasource but I need to customize fonts, sizes and layouts. What would be the best way to do this. There's not much data only 8 rows and 3 cloums.
It's for a display screen that will show workers how much product they have produced.
I was looking at binding the data to lables and laying out the lables in a table but that process looks intense and streching my knowledge.

I am trying to achieve a list view with this structure.I have many categories with many products
<table>
<tr>
<td colspan="3"><h2>Cat1</h2></td>[code]...
As you see the <td> for products must always be no more than 3 columns. but if there are 8 products then there will be 3 rows (2 full rows and one row with only 2 products) So far I have this:
<asp:ListView ID="lvProducts" runat="server">
<LayoutTemplate>
<table cellpadding="0" cellspacing="0" border="0" width="800"> [code]...
it doesn't work .

I'm learning ASP.Net for the first time having spent all my Windows development time doing client applications in VS.Net. As you know, when you drop buttons and text box controls (to name but two) onto a form you can drag-and-drop them anywhere on the form and use the cursor arrows to nudge them to precise locations. When I've created .aspx pages and I select controls from the toolbox they always appear left-justified on the page. There is no way that I can see where I can move the control around the form.
Can someone tell me how I can do that? As an example, it's typical Windows application style to have main form buttons on the lower right corner of a form. But I can't seem to find a way of putting controls anywhere on a page except on the left-hand side. I'm probably racing ahead of myself but I reckon this a reasonable thing to do so could someone briefly describe it to me?

I want to be able to persist data across a session but do this outside of the built-in session state object. Why is a long story that I will not go into here. I just need to know where I can put data other than in the session object that will persist across the specific session.

Is it possible to use mixed cookieless sessions with cookie sessions? I've an application that captured user details and then redirect for payment to an ssl page. I was wondering if this is possible? [URL] redirects to [URL] Note: the session Id in the latter url. So in essence, we use the standard cookie session for the majority of the application but when we transfer to an ssl page we pass the SessionId to the https url to pick up the session. I've tried this locally but it starts a new session.
