Evaluates data-binding expressions at run time.
Syntax
Parameters
- container
- expression
Returns
An object instance that results from the evaluation of the data-binding expression.
Remarks
The value of the expression parameter must evaluate to a public property.
This method is automatically called when you create data bindings in a rapid application development (RAD) designer such as Visual Studio. You can also use it declaratively to simplify casting to a text string. To do so, you use the <%# %> expression syntax, as used in standard ASP.NET data binding.
This method is particularly useful when binding data to controls that are in a templated list.
Because this method performs late-bound evaluation, using reflection at run time, it can cause performance to noticeably slow compared to standard ASP.NET data-binding syntax.
For any of the list Web controls, such as System.Web.UI.WebControls.GridView, System.Web.UI.WebControls.DetailsView, System.Web.UI.WebControls.DataList, or System.Web.UI.WebControls.Repeater, container should be Container.DataItem. If you are binding against the page, container should be Page.
Starting in .NET Framework 4.5, you can use model binding to simplify some of the tasks that you had to perform through data-binding in earlier versions. For a tutorial series on using model binding with Web Forms, see tp://go.microsoft.com/fwlink/?LinkId=286117.
