c# - How to remove Client Script Resource in the lifecycle? -

in base class, pre-render adds javascript page. in derived class, want replace javascript 1 of own resource script.

if script being added in base class:

this.page.clientscript.registerclientscriptresource(typeof(geomappingeditor), "somespace.resources.scripts.geomapping.js"); 

then can this:

protected override void onprerender(eventargs e) {     base.onprerender(e);      //how overwrite javascript file here? } 

the reason why thought may possible because javascript added onto page key this:

this.page.clientscript.registerclientscriptinclude("geomapping", this.apiscript); 

so know can add script in page "geomapping" being key , overwrite previous script. not seem there key "registerclientscriptresource". ideas on how achieve this?

in base class, add virtual/overridable method register script, , in base class, override method , don't call base implementation. override it.
