[System.Web.Services.WebMethod] 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?
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! I can't either use their properties "onclick" to call i method i created in the code behind.Is there a way to do it ?
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?
I have a Java Script method that is called from an Aspx page named Default.aspx. The Java Script method is calledwhen a linked button on that page is pressed.
function Redir() { window.status=""; va urlGetit = "ConvertToExcel.aspx?" + "&test=" + 7; xmlhttp = new XMLHttpRequest(); xmlhttp.open("GET",urlGetit,true) }
This Java Script method then calls my Code behind file named ConvertToExcel.aspx.cs" where I build an MS Excel file
We're having a problem in our ASP.Net application where the Crystal Reports engine leaves garbage .tmp files in the server's Temp folder after generating reports for the users.So we're trying to figure out how to run the .Close() and .Dispose() methods on the Report object, but we're finding that the code never gets run after the export occurs.
Breakpoints set on the last two lines never get hit, and we've also tried putting other code there to test the processing. None of it runs. (I've also seen this question on other sites with similar code, but no answers)I assume the ExportToHttpResponse method is returning a file stream (PDF) to the user at that point, ending the processing so the rest of the code doesn't get run. If that's the case, how do we get CR to perform a cleanup on the temp files, which the Close() and Dispose() methods are supposed to do? Do we have to implement a manual after-the-fact cleanup?
If I have a web form with a button control on it. Is their a way to have it's button press method called from a Java Script method? Can someone show me how to do this?I have a hidden button on a web form. I need to simulate it being pressed programatically through Java Script. So I need Java Script to run the code behind method for a button.
protected void PageButton_Click(object sender, EventArgs e) { // How to have this method called from Java Script? }
I don't know what I'm making wrong.I have a submit button, and on click it should execute the funktion in the code behind, but I get the error that the funktion is undefined.this is my code in the .aspx webform:
And now I want to set the innethml to every span control with a while end, like while dr.read I would like to set the ID to the span dynamic, like text & I.innerhtml = "something" I = I + 1 end while but how do a refer to a ID dynamic of a control in the code?
I have an ActiveX object which extends some functions. I have a web page that loads the ActiveX object and calls its methods in Javascript. The ActiveX object has two method; the problem is that Javascript can successfully call one of them but fails to call the other; citing Object doesn't support this property or method which is nonsense because I made a VB6.0 application that successfully calls this other method, so the two functions are indeed extended correctly and performing their job. And yes, the Internet Explorer security zones are all set and everything, as I wrote above the javascript code can call one method but refuses to call the other.
what i have is a form and when i click on a icon then in javascript it pops up a window with data bound to a grid. Now on that form if i hit tab in a particular text box how can i call that same window ( ie just call the javascript onclick event and pass the text in the text box) ?
Normally I use this control on it's own page and the button works. This time round however, I am loading this control into a Div that is present on the home page of my site (that way I can show the contents with a little bit of JQuery). However, when I bring the control in this way, the onClick event doesn't fire and I am not sure what could cause that.
I don't have any code sample but the nature of the site makes it difficult to provide any that would make sense.
In short, what would stop this event firing now?
p.s I have tried adding validation groups to all other buttons and validation controls on the page and there is only ONE form present on the page.
EDIT: I have only just added the validation stuff in to see if that does anything. By default it has been like this and still didn't work:
As mentioned as well, this works when I use this control on it's own page (loaded directly into Default.aspx) so I don't think the case of onClick matters.
EDIT2: I have just noticed that when I click this button, other validation controls on my page are being triggered even though they have their own DIFFERENT validation group?!
If I use an ImageButton or LinkButton, I just noticed that when clicking either, the Page_Load method executes before the method specified in the OnClick. Can this be avoided so that the method in the OnClick is triggered instead of Page_Load?
