Binding from codebehind (ASP.NET)

I have SqlDataSource assigned to a GridView, and a lot of the fields retur开发者_如何学Cned are only used in the code behind to determine whether a column is visible, etc. Currently I bind these vlaues to a hiddenfield, however this adds a lot of code to the source file which isn't ideal.

Can I get the values for the row from the codebehind, without having to assign them to a hiddenfield in the markup?

In your code behind, you can access the values through the DataItem object

Example

DataRowView rowView = (DataRowView)e.Row.DataItem;

// Retrieve the state value for the current row. 

String state = rowView["state"].ToString();

Or you could convert the value to an object and play around with it.
