datagrid and itemCreated

[cjburkha]

Hi all

If I wire up itemCreated and insert this code:
If e.Item.ItemType = ListItemType.Footer Then
Response.Write("got the footer!")
end if

I get "got the footer" written to my page 3 times. Does anyone know why this would be?

How many columns do you have? and records?

 

[cjburkha]

I have 5 visible collums, and 7 total.

I'm not sure about records, it seems to happen no matter how many records I have, but it ranges on these pages from 2-8.

Try stepping though your code - it will give you an indication of why it happens (i.e. is it there there are several items that all have a listitemtype of footer.)

I have, and I don't think I fully understand what all happens in building a datagrid.

Here is msdn

The ItemCreated event is raised when an item in the DataGrid control is created, both during round-trips and at the time data is bound to the control.

So my understanding is that when a row is created, itemCreated will fire, and when the data is bound to the row, itemCreated will fire. That explains two, not three.

Specifically,

are several items that all have a listitemtype of footer

No, there is only one footer in this datagrid. I do have template collums with editItemTemplate specified, so maybe it fires once for normal colums which use the datagrid footer, once for templatecollums looking for a specific footer, and once for databinding. I'll try and test for that.

That doesn't make perfect sense though, because it should fire twice for normal columns (round trip and data binding) and twice for template columns (round trip and data binding)

Thanks for your help guys,
