Design And Encapsulation Ajax Components Based On ASP.NET

Ajax is shorthand for Asynchronous JavaScript + XML, it isn't a technology. It's really several technologies, each flourishing in its own right, coming together in powerful new ways. With Ajax, users of B / S structure also can match the "WYSIWYG" experience, which was only for C/S users. Because of components'advantages of reusable, easy to maintain and support a seamless upgrade, Microsoft Co. has packaged ASP.NET Ajax components, but there is also room for improvement.According to the actual needs put forward by the developers, 6 Ajax components based on ASP.NET were designed and encapsulated. They are multi-selected tree component, radio tree component, cascade component, list for query and selected component, paging component and re-confirm component. These 6 components all make their best use: 1st supports for the deep-rooted relations multi-selected, 2nd for any level of individual choice nodes, 3rd has the support of the relationship between the level of data linked to choose, 4th supports for individual choice and fuzzy inquiry, 5th supports for the separation of control and paging functions, navigation through the page button, 6th supports the user to reconfirm the potential disoperation.Test result shows that: the load speed of multi-selected tree component and radio tree component is faster than TreeView; load speed of cascade component and multi-level list for query and selected component is in 10s ; paging component is efficient than ASP.NET page components; re-confirm component effectively reduced the user's disoperation rate.
