Web Forms :: Access Page Load Event From User Control

Mar 2, 2010

I have a page called "EDIT.ASPX" on that page it has come TextBoxes, Label and 3 User Controls. When the Edit.aspx page is loaded all the correction form Controls are loaded properly, even the User Controls loads with no problem. The problem that I am expericing is that on the User Control I have a CHECKBOX with AutoPostBack="true". Each time the user click the CheckBox the User Control disappear. NOTE: How do I fix this problem and eliminate my page control from vanshing. The user control needs to keep the same state as the Edit.aspx page when the checkbox is clicked. I need to be able to click the checkbox without loosing any data on the page rather it's the Edit Page or the User Control.

MVC :: How To Create And Add A Embeded Javascript-resource File By Useing A HtmlHelper

Jan 8, 2011

I have written a smal HtmlHelper, but the thing is that I whould require some javascript functionallity to this helper. So I thought "Whouldnt it be great to actually let the framework add the javascript <script>-tag to the head-element of my Html document once I use this helper?"

So what I whould need/like to do is:

1. Add the Javascript-file as a resource to the dll, since this will allow me to always have the javascript file together with my HtmlHelper, so I dont need to have a seperate file for the js.

2. Add a <script src="{my js-resource}" /> to the head-element of my html document as soon as I use my helper...this is kind of the tricky part..since Im not realy sure about how to do this in MVC...if its even possible..the best sulotion whould be if I didnt need to add any other code in any other file then just in my HtmlHelper...(no code needed to be added in my views or controls) To put it all kind of simple...from what I recall..I want to more or less register a start up script, as its called in WebForms..but in MVC..(I saw an example of how to do it ClientScriptManager, but that whould require me to add extra code on my views and layout/masterpage-files...which simply doesnt do it for me if there is any other way)
