ASP .NET - Data Binding and Formatting Problem

Data 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.

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:

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

Hello Steve,

Thank you for a swift response.
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.

Kind regards,

Thomas Jastrzebski
