Forms Data Controls :: Bind A Value In The Form When There Is A Null Value Previously In The Database (SQL)?

Jan 12, 2010

I am using a FormView control. The allows me to update records in the database. However, when a database field is null I can not update the field on the form. It works fine when the field is not a null value. I am not using any code behind (C#) to bind the data or manipulate the data.

I have read that when there is a null value in the database thatthere is no record in the "dataset". Can anyone show me how to bind a value in the form when there is a null value previously.

Forms Data Controls :: Displaying A Null Or Empty Cell For A Null Datetime Database Value In Gridview?

Dec 6, 2010

I have setup my business object to have a create_date and edit_date members both datetime datatypes. My company want to display the create_date and edit_date fields in a gridview for each transaction. The problem i have is that after insterting a record it will have a valid create_date but no edit_date and when displayed in the gridview it defaults to datetime.minvalue (My default). How on earth do i show an empty field in my gridview for a null datetime field in the database?

I am using similar architecture to the Imar Spaanjaars example of a tiered solution. With a few small tweeks it has worked well for me for ages. I am passing a List<Database> to my object datasource which connects to my gridview.

Web Forms :: How To Bind Field In Form View To Different Data Set

Feb 2, 2010

This is probably a simple question, but I can't seem to find an answer. One of my web pages has an ASP.NET FormView and two SqlDataSource controls. I need to show data from both datasource controls in the FormView. Most of the data will come from datasource1, with 2 or 3 items coming from datasource 2. The way I am trying to do this is by adding a label to the formview, then use custom data binding to get the data from datasource2. However, I can't seem to figure out the syntax for the bind statement
