.NET Forum / ASP.NET / General / April 2008Data Binding and Formatting Problem
Hello developers, I bind my TextBox control specyfying a format stored in my application global ApplicationContext object - it has a static string CurrencyFormat property. The problem - this works fine: Text='<%# Eval("Price", ApplicationContext.CurrencyFormat) %>' but this does not: Text='<%# Bind("Price", ApplicationContext.CurrencyFormat) %>' (Parser Error Message: A call to Bind was not well formatted) Could anyone suggest a solution? The objective: store format strings globally. Thank you for any hints. Thomas Jastrzebski Hi Tomasz, Regarding on the Databinding expression issue you mentioned, I've performed some tests and did encounter the behavior you mentioned. I've checked the document, though the formatting of "Bind" is not definitely documented, it mentioned that Bind doesn't provide the exact same set of databound functionality like Eval. For example, Eval support complex hierarchy class object databound while Bind not. The NumberFomatInfo should also be limited by the Bind expression. I'll help you forward the problem to some other ASP.NET engineers to see whether they have any further ideas on this. You can also submit the problem to our connect site: http://connect.microsoft.com/feedback/default.aspx?SiteID=210 So far, as a workaround, you may need to use Eval instead of Bind for the display formatting. And manually set the parameter for editing/updating. Sincerely, Steven Cheng Microsoft MSDN Online Support Lead Delighting our customers is our #1 priority.

I cannot use Eval - I presented this code for a problem demonstration only. Eval provides one-way binding only, while I also need to unbind my data in order to store user changes.

They told me that this is an by-design behavior. The Bind() statement doesn't allow specifying any format info. It just allows a a field name and an optional format string. And one of the dev engineers has published a blog entry describe how bind expression works: http://weblogs.asp.net/leftslipper/archive/2007/06/29/how-asp-net-databindin g-deals-with-eval-and-bind-statements.aspx Sincerely, Steven Cheng Microsoft MSDN Online Support Lead Delighting our customers is our #1 priority.

I know Bind does not support format info. I never tried to use it that way. The point is that it does not also support format string as expressions. It supports constant strings - predefined formats only. Thomas > Hi Tomasz, > [quoted text clipped - 158 lines] >>>>> >>>>>Thomas Jastrzebski Hi Tomasz, Yes, only a simple constant format string is allowed in the Bind expression. Actually, as Elion mentioned in his blog entry, Bind expression will not allow any format expression that is generated by additional function call or operates. However, I think it's a good suggestion that the Bind expression be improved to support more formatting options.
