ASP Net - Need to add Button to DataList

02-21-2006, 01:55 AM

Hello,

I need to add extra buttons to a datalist, but I don't know to add them to
the control. I need to use the onCommand Functions, like OnUpdate, OnEdit,
OnUpdate, OnCanel, Etc. I would like to do this VB.Net is that is can be
done. Any help would be great, I have been trying to do this for a while
and need help.

Thanks in advance for any help,

Jack

Hi Jack,

I'm not really clear on what your problem is or what's not working for you.
Perhaps you could elaborate? It the meantime, the code below (ASP.NET 2.0)
inserts buttons into a datalist template.

Let us know?

Well, add a Button Control to the template just like you would any other
Control. Then set the CommandName property of the Button. Depending on what
CommandName you chose, one of the following events will be triggered when
the button is clicked, depending on the value of CommandName:

"edit" EditCommand
"update" UpdateCommand
"cancel" CancelCommand
"delete" DeleteCommand
"item" ItemCommand

You can then determine which Item's button was clicked by using properties
such as e.Item.ItemIndex. The Button also contains an optional
CommandArgument property which is passed as well (if you use this property
you will probably assign it a value in the ItemDataBound event). The e
parameter, which is passed to the eventhandler, also contains several other
properties. For more info, see the documentation or for a specific question
feel free to ask. (Don't worry, it took me a while to figure this out also)
Good Luck!
