That means that the variable form is null.
What does the variable contain from start? Why are you using FindControl to try to get a reference to the page?

You are in the page. All events for a page are methods in the class for the page.

There are references in the page for all server controls in the page. The reference has the same name as the id of the control.

There are no IEnum or IClone interfaces in the framework. Is it IEnumerable and IClonable that you mean?
IEnumerable is used for classes that can be iterated, like arrays, lists and collections.
IClonable is used for classes that supports cloning. That means that the class can produce a copy of itself.

hi
try this:
when you load the data into the datagrid, you can use the item_databound event to change the number to the image it self, try something like this:
e.item.cells(3).text = replace(e.item.cell(3).text,""
hope this will give u some idea

you can use onitemdatabound event of the datagrid, that event gets fired for all the rows of the datagrid.

hi,
as one of our friends said ( c the "datagrid" Query) this is really good site for DataGrid. try to check this site.
http://www.datagridgirl.com/articles.aspx
as per my opinion, it is not a good idea to create dynamic rows in datagrid. it will give u the performance issue.
thanks,
