如何让EXT.NET支持视图变量ViewState

根据以上的说明，我们可以对 EXT.NET 进行很多配置。

比如，让 EXT.NET 支持视图变量。默认情况下，EXT.NET不保存页面变量，但是可以通过配置EXT.NET改变这点，毕竟有时使用ViewState还是挺方便的。

WEB.CONFIG配置

<configSections>
……  <section name="extnet" type="Ext.Net.GlobalConfig" requirePermission="false" ></section>
</configSections>
<extnet ajaxViewStateMode="Enabled" />

<httpHandlers>
……  <add path="*/ext.axd" verb="*" type="Ext.Net.ResourceHandler" validate="false" />
</httpHandlers>
