School aschool = new School();
aschool.SchoolId = CurrentSchool.SchoolId;

C# - How To Call A Javascript Method From Code - Behind Web Method

Jan 25, 2011

I have a web method in my code behind:

public static string GetStateData(string state)
//this is where i want to call a javascript method "GetItems"

I have a javascript method that retrieves some values for me and I want to get use one of those values in my web method

function GetItems() {
var variable1= $("#<%=Item1.ClientID %> input:checked");
var variable2= $("#<%=Item2.ClientID %>").val();
return [variable1.text(), variable2.val(), variable2];}

I've searched for ways to call the javascript method from the web method but every time my search results in how to call a web method from javascript.

I did find this but it was done from the code-behind of a silverlight project and when I tried adding the correct reference to my code-behind it wasn't there

var result = HtmlPage.Window.Invoke("GetItems"); Is there a reference I'm missing?

C# - Calling A Code Behind Method Based On A Click Event

Mar 5, 2010

I currently have this working but it requires me to have a static method as the method called in the code behind. I would like to be able to access some member variables that can't be static.

EDIT: Let me clarify, I'm looking to edit a value in one of the user controls on the page based on the button click. I am holding the user controls in a list on the page and using the parameters passed through the javascript to find the user control that I want to update and modify the value there.

It currently looks like this:


function incrementCompletes(obj)
var firstParameter = $(obj).parents('.parentClass1').find('.childClass1').html();
var secondParameter = $(obj).parents('.parentClass2').find('.childClass2').html();


I would like to find a solution that does not require the method called to be static.

Wy To Bind A Button On Click Event In Code Behind

Oct 29, 2010

I'm building a button in my code behind file and want to bind the click function to an existing click function of a different button. How do I handle this? I was hoping for something simple like:

Button b = new Button();
b.onClick = otherClickEvent();

but apparently that's not doable. Am I missing something here. I'm aware of OnClientClick, but that only deals with the JS side of things apparently.

Web Forms :: How To Disable The Button And Run Processing Code During The Click Event

Dec 16, 2010


1) Click on 'Check' button and the button will disable

2) Run a processing code(for checking) and once it is done, navigate to a new page(NewPage2).

Here are 2 code situations (1):


and if I do this way (2),:


it will navigate to NewPage2.aspx, but during the execution of the processing code, ButtonCheck control will not be disabled as the Click Event has not finished, and I want it to disable during the checking process. If the 1st option is executed, it will throw to me "Response is not available in this context."? HttpContext is null for (1). In my opinion, I think that the navigation does not recognise the response object as it is in a thread and has exited out of the buttoncheck event. But I'm still not sure why.

how to disable the button and run processing code during the click event and be able to navigate to a new page?

Web Forms :: How To Call A Method Of Code Behind From ASP.Net

Feb 17, 2011

I am just learning ASP.Net and i am more using C# as code behind than vb.I am trying to call a method of the code behind (file.aspx.cs) from the (file.aspx).I know how to do it the easy way:- create a button from ASP.Net and double click on it than the property "onclick" will be linked to the method.But i don't know how to do it from a query:

- By example, from an Access database,i use the syste, [using System.Data.OleDb;] and i made a query and display it into a standar object named "Table" which has rows (tablerow) and cells (tablecell) and the cells have one of their properties which is "Controls" where developers can add button (regular button, image button, link button, etc). With i display the buttons from the database, i can not call a method from code behind!

C# - Call A Method Inside Code-behind Using JQuery?

Feb 9, 2010

My pages base on master and content pages and in content pages I have Multiviews; inside Multiviews I have RadComboBoxes.Two of my RadComboBoxes are parent and child, like country and city dropdowns. Therefore in code-behind I put some code in the OnSelectedIndexChange event of parent RadComboBox for filling its child; I use a hidden field for country id and sql datasources (stored procedures). Meantime parent and child combo boxes are in an update panel.For doing this job i set the autopostback property of parent combobox to true,but I do not want that autopostback=true because of some focus problems that I coded with jQuery.So I want to convert the OnSelectedIndexChange event in code-behind to a method and call it in jQuery (in change event or something like that of parent combobox). How can I do this?
