Databinder. Eval Method

Show all
Use reflection to analyze and compute the data binding expression of an object at runtime. This method allows the rad designer (such as Visual Studio. NET) to easily generate and analyze data binding syntaxes. This method can also be used on web forms pages through declaration to simplify conversions between types.

Reload list
Calculates the data binding expression during runtime.

[C #] public static object eval (object, string );

Calculate the data binding expression at runtime and format the result to the text to be displayed in the request browser.

[C #] public static string eval (object, String, string );

Example
[Visual Basic, C #, JScript] the following example shows how to use the eval method in Declaration to bind a price field. The container syntax used in this example assumes that you are using a list web server control. The format parameter format the number to set a specific currency string for the area displayed by the request browser.

[Visual Basic, C #, JScript] Note that this example shows how to use an overloaded version of eval. For other examples available, see separate overload topics.

[C #]
<% # Databinder. eval (container. dataitem, "price", "{0: c}") %>
