Javascript - Call A Code-behind Function With Ajax?
May 19, 2012
Searched a bit, couldn't find a clear answer.I have a big HTML table with numbers in it. I have a selector (radiobuttonlist) that the user can click if he wants to see the table in $ or days.Right now it works perfectly but the page refreshes because i'm calling a code-behind function (RefreshTable) everytime the user clicks on one of the two radiobutton since it changes the format and needs new calculation done by the RefreshTable function
. Is there any ways I can call that function without refreshing the page using ajax or something ?
The function has only one parameter : ProjectID, it's coded in VB.NET and we're using ASP.NET
Here's the table code from the .ASPX page, it's only the shell, everything is added thru a VB.NET method called when the RadioButton is changed (autopostback=true), so we check wich one is selected and execute the VB.NET method to populate the table. (code of the function is below)
I have a function that is responsible for populating an SSRS report. The user presses a button and I go out and check to see if there is data. If no data, I provide a NO DATA message. If there is data I call the SSRS report which I would like to open in a new window.
<script type="text/javascript"> function openWindow(url) { document.forms[0].target = "_blank"; } </script>
I have an ASP.NET application with a button that executes VB.NET on the server when clicked. Specs have changed, I've added a menu of sorts which is to replace the VB button. With some from S.O., I've managed to manipulate some javascript which does a postback and executes the button's code. I figured I could just make the button invisible and still be able to call it's on_click event from js. How wrong I was!
So now, somehow I'm supposed to call a VB sub from either javascript or (boss says) ajax. I have no idea how to do this. Could anyone give me a good direction as to how I can call a VB.NET subroutine from ajax on the client? Or javascript?
In the above code I am having issue debugging. The point of this is in the HTML I have three select tags.District, County, and City. If you select a District it should update County and City to limit only the Counties or Cities in that District. City works perfectly but County does not. I discovered that when running through this code above if it runs through the County Case segment it just stops filter = String.Format("maintdisnmbr in ({}0)", filterValue). If I step through step by step the code does not finish. If I don't go step by step and jump ahead it gives me an error saying the Input string is not formatted.

In my project, there are 3 user controls; BasicContact, BasicDetail and ActionTime. They are in EditOrder.aspx page. There is "ReportDate" property (Date type) in BasicContact, RadioButtonList "rdl_Priority" (with integer value from "prio_id" field) in BasicDetail and "CheckDate" property in ActionTime. The ReportDate value is derived from txt_ReportDate and txt_ReportTime and CheckDate value is derived from txt_CheckDate and txt_CheckTime.

Basically, I have a gridview that is opened in a new window from the parent window. It has a bunch of records with a view button to view the details of each record (which stays in the same newly opened window). I have a calendar in the parent window that accepts a Date querystring parameter to set the current date on the calendar at page load. I'm just trying to refresh the calendar in the parent window to match the date of the label in the newly opened window.
All the code below is in the newly opened window. The .Net code-behind below refers to when that view button is clicked and everything is populated. At the end, I call the js to refresh the parent window and pass the value of the LabelScheduleDate as the querystring parameter. Now the label comes through as '03/25/2010' in the code-behind, but when I pass it to the js, it comes through as '0.00005970149253731343' in the end querystring. I'm not really sure what is making the value change, and I want to pass it as just text. Do I need to pass it as a string object? I tried but I don't think I was doing it right.

I have a bunch of divs on my page that are added at run time dynamically. When any of the dynamically added divs are clicked - All need to call the same function in my code behind.

I know how to call a simple old fashion asmx webservice webthod that returns a single value as a function return result. But what if I want to return multiple output params? My current approach is to separate the params by a dividing character and parse them on teh client. Is there a better way.
I'm not sure what's wrong with the following setup. I have a View that lists a number of records, and each has a dropdown associated with it to change a value on that record. I had it all working without AJAX, but you had to change a bunch of the dropdowns then click a Submit button. I wanted to change it so that it would save the dropdown choice immediately.
My stripped down View (of type IEnumerable(Of MyTable)):
What I would like to happen is for the dropdown change to trigger the Update controller, but probably not return anything - just update the database and let the user move on. What's happening though is that a blank page is displayed with the Content value on it (i.e. "123: ABC"). It's the correct id/code combo, so the Update seems to be firing correctly, it's just choosing to wipe out the html.
I accept both C# and VB.NET If you visit this [URL].. and then click on the link like the image below you'll see in-line pop-up DIV which displays a busy status of Ajax callback before it displays the information. So, the information is not there yet until you click on the link.
I'd like to do the same but ASP.NET and jQuery. If there's any place to help me get started on the right track?
