ASP.NET ListView: how to insert a "specific" element into every N elements?

Question

I would like to do a “weird” thing with the asp.net list control.

I would like to insert an advertisement for each element of the 8-10 list (linked to a database with a database table): for example, each element of 8-10 inserts google adwords jscript code.

I googoled, but I did not find anything. Someone knows whether it’s possible to “tell the list: every 8 points, show this element (google jscript code).

Excuse me for my poor English. Hope to be explained, thanks!

Answer 1

You can achieve this effect by grouping your items. You will need the following:

• LayoutTemplate in your ListView that contains groupPlaceholder
• A group template in a ListView containing an itemPlaceholder
• The GroupSeparatorTemplate panel containing your promotional materials.
• ItemTemplate element containing data binding material

then you can configure your GroupSize the way you want, and ASP.Net will automatically add a separator between each group.

Answer 2

for(int i = 0; i < limit; i++) { if(i % 8 == 0) addSpecialColumn(); } 

Hope this helps.

Here are a few theories.
