长答案:

.NET 4 现在可以让您选择 ClientIDMode :

类型:System.Web.UI.ClientIDMode
指示如何生成 ClientID 属性的值。

AutoID
The ClientID value is generated by concatenating the ID valuesof each parent naming container with the ID value of the control. Indata-binding scenarios where multiple instances of a control arerendered, an incrementing value is inserted in front of the control'sID value. Each segment is separated by an underscore character (_).This algorithm was used in versions of ASP.NET earlier than ASP.NET 4.

Static
The ClientID value is set to the value of the ID property. Ifthe control is a naming container, the control is used as the top ofthe hierarchy of naming containers for any controls that it contains.

Predictable
This algorithm is used for controls that are in data-boundcontrols. The ClientID value is generated by concatenating theClientID value of the parent naming container with the ID value of thecontrol. If the control is a data-bound control that generatesmultiple rows, the value of the data field specified in theClientIDRowSuffix property is added at the end. For the GridViewcontrol, multiple data fields can be specified. If theClientIDRowSuffix property is blank, a sequential number is added atthe end instead of a data-field value. This number begins at zero andis incremented by 1 for each row. Each segment is separated by anunderscore character (_).

Inherit
The control inherits the ClientIDMode setting of its NamingContainer control. This is the default.
