ASP.NET Button UseSubmitBehavior property
Button controls Definition and Usage
UseSubmitBehavior attribute specifies the Button control uses the client browser's built-commit feature, or use the ASP.NET postback mechanism.
If the control is to use the browser to submit features, the property is set to TRUE. Otherwise FALSE. The default value is TRUE.
When set to FALSE UseSubmitBehavior, ASP.NET adds a client-side script to post the form. At this time control developers can use the method to return Button GetPostBackEventReference client postback event. GetPostBackEventReference method returns a string containing the text client function calls that can be inserted into the client-side event handler.
