从代码隐藏（ASP.NET）进行绑定

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?

Answer 1

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.
