Binding from codebehind (ASP.NET)

Question

I have SqlDataSource assigned to a GridView, and a lot of the fields returned 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?

I don't see why you couldn't - perhaps handle the one of the DataBinding or Creating events for the GridView, and pull the information you need from the SqlDataSource? If I had more time, I'd try and put together a sample to verify it, but it seems like a plausible approach. — Tim

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.
