EDIT & DELETE grid buttons don't work

[Rudy]

Hello all,
Going to make this short and sweet for now, need to dig myself out of a foot
of snow this morning. :( I have a data Grid, everything work well, except
for the button. Here is my error: "Index was out of range. Must be
non-negative and less than the size of the collection. Parameter name: index"
Source Error:


Line 275: ' if the user checked a box in a CheckBoxList control,
you could check to see
Line 276: ' if the value SelectedIndex property was > -1.)
Line 277:
DeleteItem(grdProducts.DataKeys(e.Item.ItemIndex). ToString)
Line 278: End If
Line 279:

I'm assuming the index would be my key column. I guess I don't really
understand how the index works.
If someone knows a good sample or HOW To, that would be great!

Thanks for the help!

[url]http://www.aspnetpro.com/newsletterarticle/2003/03/asp200303wf_l/asp200303wf_l.asp[/url]
See how they use index in this and you will get the concept of index..
Another one here : [url]http://www.developerfusion.com/show/3801/5/[/url]
And another one that incorporates, edit,delte and paging into one article
here : [url]http://www.c-sharpcorner.com/asp/Code/northwindLC.asp[/url]

Btw, the error means that the index that you are passing is our of range.
something like : if you have 6 objects and you are looking for the 7th
object..
Hth...
