clean way to delete item on cart 1

[matthewking]

hi all,

i want an x 'button/link' on my datagrid, that posts back and lets me retrieve a value (primary key) associated with it so I can perform the action, namely delete item, is there a way to do this or do i have to create a link? e.g. cart.aspx?action=delete&id=4503

You will need to keep track of which index in the datagrid goes to which primary key in the database. When OnItemCommand fires to a handler, it'll need a sender and the event arguments, like so:

void Command_Grid(Object sender, DataGridCommandEventArgs e)

If you look at DataGridCommandEventArgs in documentation, you will find that e.Item.ItemIndex will get you part of the way. If you hit the datatable that you populate the DataGrid with at that index, you should get your primary key.

Thanks very much merlyn2450,

Ok, so theres not a direct method of achieving this, do you think it is better to use this approach or the url posting one? e.g. cart.aspx?action=del&id=4

Thanks for the response.

I use the index method.

Querystrings are soooo ASP
