I think you'll want to look at the ItemCommand event instead of selected index changed because when you click you're dealing with button. This gives you a reference to the row, and from there you can access the data items and content of the row selected.

protected void ItemCommand(object sender, DataGridCommandEventArgs e) 
{
	// *** Button command Names contain Sku value if set
	if (e.CommandName != null && e.CommandName != "" && e.CommandName != "Page") 
	{
		// *** If we clicked on one of the items to buy - redirect to the item page
		string sku = e.CommandName;
		string qty = ((TextBox) e.Item.FindControl("qty")).Text;
		if (sku != null && sku!="") 
		{
			Server.Transfer("Item.aspx?sku=" + sku.Trim() + "&qty=" + qty + "&Action=Add");
			//Response.Redirect("Item.aspx?sku=" + sku.Trim() + "&qty=" + qty + "&Action=Add");
		}
		
	}
}

Note that you have to make sure you filter this correctly - especially filtering out Paging commands if your data grid has paging enabled.


I would highly recommend you get a book for this as a reference. Dino Esposito's Professional ASP.Net has a lot of this stuff covered in a way that's both readable and easy to find for reference even though it's very thourough.

I know I had a heck of a time with the DataGrid as well - basically it works great for the base stuff, but when you want to do more complex stuff you really have to know what events fire. Tough.
