I've been searching in all the forums, and websites for the last 4 hours without finding a solution for a problem that in the beginning I tought it was an easy one!!!This is my problem, I have a gridview with the following colums: select (link), Room Type (for hotels), and TotalThe total field Is a template field it has in the custom binding property a function: find_total(Eval("Room")) this function makes some calculation and returns the calculated Total value, and shows in the gridview without problems,The thing I cant do is: when the user clicks on the select link I want to get the text of the template field and put in a label control.
I tried, almost all the events of the datagrid, to reference the content of my template field but sometimes I receive a null value (seems that Im looking for the value before the find_total function has been executed) or I get an error "the index is out of range".I dont know how to approach this, I tought It has to be much easier, but Im very confused right now, if anybody knows how to do this

Now management wants to SUM the Date's information by column, I have figured out how to do this by changing the BoundField to a TemplateField and then add a FooterTemplate with a SQL DataSource. When I Press either the Previous or Forward button the data does not change in my Sum'd Footer column.
