multiple itemtemplates datalist

[krallabandi]

Hi, Can a datalist supports multiple itemtemplates? I want to have 2
itemtemplates in a single datalist. In 1st template I will display the
data from one dataset and in another I will display data from 2nd
dataset.

Is it possible? any knowledge base article for this?

Thanks.

You could set the template programmatically to do this. The DataList
only supports one ItemTemplate by default. Here is an example which
also uses databinding usually found in a DataList template markup. The
AnnouncementsControl is some random control I've built a while ago.

Using two of these classes, you could achieve your goal.
With this sort of code, you can call something like

myDataList.ItemTemplate = new
AnnouncementsTemplate(myAnnouncementsControl)
