How to call asp.net method from jQuery / client side in VS 2005 ....
View 1 RepliesI am using two listbox for moving items from one to another using jquery. Auto postback is set to false for both the listboxes. Is there a way to access the items server side on postback?
View 3 RepliesI am using VS2010 and .NET4 for a web app. I have a script manager/update panel that has a couple of grids.
The client just leaves the page opens and views an updated grid every 30 seconds or so.
I want to refresh the grid by calling the server side method to load the grid, but not load the whol page using meta refresh or similar (too much screen flicker and unnecessary bandwith).
Is it possible to set some timer using javascript or something and call a specific server method to refresh controls?
I have some validation JS code on client, that must be executed befor PostBack.If this validation code return 'false', postback is needless.How it can be disabled?
View 5 RepliesI've inherited some code which breaks a page up into tabs using divs. On the first page there are many required field and regex validators. The problem is a user can switch to another tab, trigger a postback and fail the validators on the first page, leaving things in a mess.
What I want to be able to do is perform the validation on the first page as a user selects another tab, thus preventing them from moving to a new tab until the first page is valid.
<ul>
<li><a href="#tab1">Tab 1</a> </li>
<li><a href="#tab2" onclick="return isValid();">Tab 2</a></li>
<li><a href="#tab3" onclick="return isValid();">Tab 3</a></li>
</ul>
[Code]....
Note use of jQuery for cross-browser compatibility with click event. And this only works if there are no validators on other tabs, as per Thomas' answer, I'll need to use validation groups and extra logic in isValid if any get added.
I am developing a web page where a user will submit some "Comments" on a form. When they click the submit button, I fire off some javascript that captures their current GPS location, which I store in a visible Text Box (for testing purposes). If the user is updating from a device that doesn't support gps, I add text to my textbox that says "Device does not support GPS".
When I get to the server, using a device that doesn't support GPS, that text comes through just fine. When I use my iPhone, I see the GPS Coords in my textbox, but that textbox value doesn't make it to the server.I'm thinking that there is a 2-3 second delay from the time that the button is clicked to the time that the java finishes retrieving the GPS. So the textbox text isn't set fast enough.I'm wanting to prevent a postback for 3 seconds (for example) to give the javascript time to update the textbox.
I have a ListView that contains a large collection of rows with textboxes that users can optionally fill out. These textboxes are not databound. When the user clicks "next" i need to iterate over the rows and determine which fields the user has filled out, and then update a sort of "cart" with the data and move to a confirmation page ("you have selected a, g, v, zz, is this correct?" sort of thing).
I can think of two ways to deal with this. The first is, server side, to walk the items in the listview, get the control ID's, save this data to a list, then save it to a database cart table for the next screen to read.I can use jquery to collect all the values client side, then pass it back to the form in a hidden field and use something like Newton.Json to get the data into a similar list.What are the tradoffs of these two approaches?
Using this script on a button click
[Code]....
After it is done, I can't click on my calendar control. I was hoping to add somethign that would force a refresh in the script, but nothing I do works.
Basically I want to get some javascript to be sent back to the client and executed from a postback inside an UpdatePanel. Furthermore this is inside of a reusable WebControl. I've tried
this.Page.ClientScript.RegisterStartupScript and this.Page.ClientScript.RegisterClientScriptBlock but Firebug shows that those scripts aren't sent back in the postback's response.
I also tried straight up writing a <script> tag inside the control's main div in the Render method, which does get sent back but isn't executed. I got a hacky solution working, but ideally looking for a cleaner solution. The hack is to add a 1x1 pixel img with width/height set to 0 and use that for an onload event to execute the script and that works, but it seems like there has to be a cleaner way to do this.
What is the best way to save BackColor of asp:Tabel TableCell set on client side by javascript on posback ?
What property do I override while creating custom control based on Table ?
I'm using what I believe is a pretty common/boring/generic implementation of a ModalPopupExtender. I'm using client-side JS to show the dialog when the user clicks a link, and hide it if they click "cancel". I only do a postback if they truly want to save the data.
I can click the link to show the dialog, then click the cancel button to hide it, then click the link to show it... ad infinitum. If I decide to save the data via a postback, everything works well, and the dialog is hidden as a result of the postback, all as expected.
However, once the postback completes, my client-side JS show() never works again. Any attempts to click the link fail quietly; no error messages, the dialog just never shows again.
I have two checkboxes: cb1 and cb2. They are both hooked up to an onClick event which checks if at least one checkbox is clicked. If this is not the case, it throws an alert and reverts the change. If a legal change was made (e.g. cb2 was checked, followed by cb1 being unchecked), the function calls the server function checkChange() which needs the object and eventargs.
I'm having trouble with the following:
Reverting the change: how can i find out which checkbox was clicked without adding an extra javascript function for the second checkbox? This has to be a scalable solution as more checkboxes may be added later.
How do I call the server function checkChange(). I am aware of "this.Page.GetPostbackEventReference" but I am confused as to the parameters it takes.
I encouter some postback issue when using GetPostBackEventReference. Here is the Scenario:I have a javascript modal popup dialog and got a button in this modal dialog which used to select things (this is NOT an asp:button control)
When this javascript dialog HTML button is clicked, it will call the MS AJAX web service call by the javascript: eval() method. And this MS AJAX web service call is dynamically generated. So the code is like this:
var serviceCall = svcCall + "(" + parameters + ")"; //dynamically generate the MS AJAX web service call here
eval(serviceCall);
//use eval to trigger the MS AJAX web service call
As you may all know, after complete the MS AJAX web service, you can define a callback function to handle the completion:
function OnComplete(result, userContext, methodName) {
//force to call postback manually
eval($(userContext[0]).val()); [code]...
As you can see, this is how I bound the asp:button (i.e. btnSelectUser) 's Click Event to the asp:hiddenfield using the GetPostBackEventReference, and set the registerForEventValidation argument to false. I have also tried to use different ValidationGroup and set the CausesValidation to false.In summarize, I bound the asp:button's Click PostBackEventReference(i.e. __doPostback(....)) to the asp:hidden field's Value attribute, and using javascript eval() to eval this hidden field's value in order to manually trigger postback.
p.s. the btnSelectUser is an asp:button control and used to call out the javascript modal dialog.
Ok, here is the Problem:In the same page, there is some asp:validator, e.g. and , and of coz, when the page run into error, this validator and callout will display to the user. e.g. When the user didn't fill in anything and submit the form, the ValidatorCalloutExtender will display a ballon and tell the user. Imagine one of this ballon/validatorCalloutExtender come out and on top of your screen at the moment.
Then you click the btnSelectUser (asp:button) to show the javascript modal dialog, and in the dialog, you Add some users, and once you hit the SELECT button inside this modal dialog, a MS AJAX web service is trigger as mentioned above, and once this web service is complete, it eval() the asp:hidden field's value (i.e. __doPostback(...))......and do the postback manually.
However, because of the validatorCalloutExtender ballon has display, it somehow cannot trigger the postback in this way, but when I close the ballon/validatorCalloutExtender, the manual postback using eval() is just working fine. Even more strange is that, when the ballon is displayed, the first time I click the SELECT button inside this modal dialog it doesn't fire the postback, however, if I do the same thing again (i.e. open up the javascript dialog, and choose some users, then click the SELECT button again). It able to do the manual postback....and I don't understand why the first time doesn't work.
I'm losing client side href. Is it possible to send it back to the server on the button submit using a variable or something?

How to call javascript method in client template (http://github.com/jquery/jquery-tmpl)
I'm having some trouble with jQuery UI. I've created a dialog with jQuery UI: so far, so good. I set up a form inside the jQuery UI dialog and then it's another story. I've written a very simple page to illustrate:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="testpage.aspx.cs" Inherits="RiverCascade.testpage" %>
<head runat="server"> [code]....
In the code above, see that I've just imported the jQuery, jQuery UI, and stylesheets and set up a page with a dialog box. There is an asp control button1 outside the dialog box and an asp control button2 inside the dialog box.
When I click on button1, the event handler gets called and all is well. However, when on click on button2, the button inside the jQuery dialog, nothing happens.Why is my web page behaving this way?
This is kind of peculiar requirement..
I am using asp.net and jQuery together
I have a link button as follows
<asp:LinkButton ID="displayBtn" runat="server" OnClick="displayBtn_Click" Text="Display
Content"></asp:LinkButton>
I will hide this link button using
style="dipsly:none;"
and want to call the postback called by click of the asp link button using some other html element say a div.
<div id="invokeTest"> Click here </div>
I tried using
$('#invokeTest').click(function(){
$('#<%=displayBtn.ClientID%>').click();
});
I have a simple page containing a GridView control that generates thead and tbody tags after rendering. In my jQuery script, I have a line that reads this way:
$('#GridView1
thead').eq(0).html()
When the page loads for the first time, this script returns an objects and works well. But when I click a button and cause a postback, it returns null. By the way, the button changes the number of the rows returned from the data source (based on the value of a textbox) and updates the grid.
Suppose I'm building a StackOverflow clone using webforms ASP.NET and jQuery. The Question page has a question, several answers, and comments under each. Requirements:Users can post new answers and comments, and edit existing ones, without postbacks. No UpdatePanels; the AJAX calls retrieve just the JSON they need, not HTML fragments. The page loads with all existing answers and comments in place (no javascript needs to run to read the page).
What I'm trying to figure out is how to do this without having to maintain two sets of markup (one that's bound on the client using some form of jQuery templating, and one that's bound on the server using traditional WebForms).
How to call the server side method on browser window close button...
View 1 RepliesI have a script that runs during the Page_Load() event which checks a database table to make sure that the user is still owns the lock on the page. If they no longer own the lock, I disable all the controls on the page and display an
error message.My thinking was that by disabling all controls during Page_Load() I could prevent any PostBack events from occuring. For example, I have a button on the page called "Save and Quit"
I have a javascript to enable text boxes when called, I want to trigger this code when a user picks value "Custom" from a dropdownlist, so that I can display/Hide these new textboxes.
function setVisibility(DropDownListID) {
var element = document.getElementById(DropDownListID);
var element1 = document.getElementById("TestBox1");
if (element.value == "Custom") {
element1.visible = !element1.visible ;
}
<asp:DropDownList ID="DateRangeDropDownList" runat="server" Enabled="True" onChange="setVisibility('DateRangeDropDownList');">
<asp:ListItem>Some Value</asp:ListItem>
<asp:ListItem>Custom</asp:ListItem>
</asp:DropDownList>
<asp:TextBox ID="TestBox1" runat="server"></asp:TextBox>
For some reason it doesn't seem to work.
I have a gridview control with delete asp:ImageButton for each row of the grid. What I would like is for a jquery dialog to pop up when a user clicks the delete button to ask if they are sure they want to delete it.
So far I have the dialog coming up just fine, Ive got buttons on that dialog and I can make the buttons call server side methods but its getting the dialog to know the ID of the row that the user has selected and then passing that to the server side code. The button in the page row is currently just an 'a' tag with the id 'dialog_link'. The jquery on the page looks like this:
$("button").button();
$("#DeleteButton").click(function () {
$.ajax({
[code]...
The dialog itself is just a set of 'div' tags. Ive thought of lots of different ways of doing this (parameter passing, session variable etc...) but cant figure out how to get any of them working.Any ideas are most welcome
How can this be done? Does this exclude the UpdatePanel functionality when it's done?
