How To Send Text Message Using JavaScript To Avoid Post Back
May 25, 2010
This is what I have implemented, for further code, how to send the text of the text box to the server to store in variable or database without post back? It can be done by using Ajax and update plane, but I would like to implement it using a JavaScript script.
I am using ASP.NET 2.0 with C#(No AJAX) in my project. In a particular web page, when the a button is clicked, some server intensive C# code runs before the same page is displayed again with the results. While code execution happens on the server in response to Button_Click event, a blank white page is shown to user on his browser in between post backs. How do i show a message in this case, that the processing is still going on and ask the user to wait? I have used javascript to show a message on page unload. But this message is also erased when the page is posted back to the server and the user sees a blank white page on his browser. How do i avoid this white page? Is there a way to show a message in the blank white page? How do i show a processing Message while the page is loading upon on Post Backs to the same Page.
I have four textbox and a button in my page. After filling the textbox. When the user click save button. A loading image should be displayed. User should not feel that the page is postback to the server,Some thing like in facebook loading image.
Being new to ASP.NET I have run into trouble building my own Whack-a-mole program. I think my problem comes from using Buttons, which by themselves send post backs to the server, making the software unusable. The looks are in place, making new buttons show up in the grid, in different places by random. However, when a button is pushed - the score doesn't change (which I feel is strange).
Not so strange is that the Button doesn't work since it sends post back to the server - reloading the UpdatePanel. I think I should use a different controller like the CheckBox and style it hard using CSS (which isn't a problem). Is this the correct way to go, or should I make use of JavaScript AJAX instead?
Note to self: This technique shouldn't be used in a public application since it put too much unwanted pressure on the web server.
I have used update panel and in that update panel I have kept ASP Table control in which I am creating rows dynamically which in turn contains 1 dropdown lists and 3 text boxes. My problem is that after partial postback text boxes and dropdown list are found but text property of text boxes is showing empty and dropdown list's selected value is set to the first record in that box. I have also stored entire table in session and retrieve it in(!isPostBack) condition at page_load event.
part of my .aspx page is as below
[code]....
I want to add one row on every addRowTbn click event there by retaining previous rows.
Disable a post back from asp.net i.e. buttons, links, gridview page index changing and sorting etc when a post back is already in progress. Target browser is IE 6+. I've written these 2 javascript I am not sure how to apply it on GridView Page Index changing.
[Code]....
But I am not sure how to attach the VerifySubmit to non prompting controls like gridview pager.
The javascript is running everytime I click the button. However, even though my subroutine updates the session variable after clicking the button, I always get the same alert. In other words, the same javascript is run after postback, and it is not updated. I am positive that the session variable IS being changed.
I have a Contact page, with 4 textboxes and 4 field validators. I made a RESET button to clear the text when pressed. But for an example: if i type on 2 textboxes and then press the RESET button, it tries to validate all 4 textboxes.
i have 10 list boxes in my aspx page for all 10 list boxes same function is using for some buttons i want to add listbox data to grid can you java script code shown below
f[code]....
i tried a javascript above code to move items between listbox using html input button problem when i trying to save listbox.items.count giving 0 can anyone tell me why this happening and also when post back occurs listbox items lost.
Im currently trying to use a jQuery plugin:jQuery Autocomplete TokenizerNow after posting back the page, I want to re-load the values back into the textbox for whatever items had been entered.Now the jQuery on the page is like below:
$(document).ready(function () { $("#<%=txtPeople.ClientID %>").tokenInput("Handler.ashx", { hintText: "Type in a name", noResultsText: "No results", searchingText: "Searching...", [code]...
I have multiple update panels in a page. how I can know which update panel caused partial page updation on client side before page is partially updated?
I have a text box inside a update panel. With the onTextChanged events, I have a post back set in "True" to show the customer Name and email when I type in the customer ID in the text box. I want to have it show when we leave or Tab out of the text box. Now is working , but only afte I click the submit button. Does anyone know how to code the following in order to make it work right away when we Tab out of the text box.
The problem is that for any other TextBox on the page which is using this MasterPage, for example the login page, if you type your user name and password and hit Enter, The page is redirected to the SearchPage. If you click on login buttton everything works fine. How do I make sure hitting enter on the page in any other text box does not post back to SearchPage.aspx?
I have put the following method in my master page. It works when I call it on a full post back, but when I call it from a updatePanel's asyncPostBack no alert is shown.
I searched google and found asynchronise post back trigger is used if we want update panel to post back on some event of control if it is out side the update panel. Than what is purpose of post back trigger ?
i have a text box that i bind to my model data and it works fine. however when i submit my form in some cases i want to change the value that in the text box so some value i pull from the db. when i do this, it only works if the form was not submitted. is there something i am not aware of when it comes to rebinding a text box from the model in cases when the form was submited, instead of reloading the same value that the user entered into the text box?
I'm trying to save some content whenever a button/hyperlink is clicked using jquery.ajax (Using Asp.net 3.5). The logic is as follows:
Through .bind in jquery I bind my own method(MakeLog) to a button click or hyperlink click. The click events of button/hyperlink contain nothing, I need to use .bind for selective controls.Now we have a button whose click event will fire a method, say MakeLog.Code snippet for MakeLog is as follows:
This works fine in IE but in Firefox this is not sending the data back as expected.I tried to identify the issue and came across the following: http://stackoverflow.com/questions/3522944/jquery-ajax-calls-async-false-vs-async-true .What I understand is that, whenver page is redirecting/reloading due to button click or hyperlink click the async call is not working properly.
I am using 3 text boxes for range selections. I want to show range value in a message box when user enters range in text box.
Suppose user enters
100 in 1st text box , I want to show "you are selected <100". 100 in 1st text box and 500 in 2nd text box I want to show "you are selected 101 - 500" 500 in 2nd text box and 1000 in 3rd text box I want to show "you are selected 501 - 1000"
After entering a value in 3rd text box ,I want to show all ranges in message box.
I am using 3 text boxes. When I click on 2nd text box I want to show 1st text box value in message box (if 1st text box passed the validations). Same procedure when i click on 3rd textbox I want to show 1st text box value and 2nd text box value in message box(if 1st text box,2nd text box passed the validations).
I have a very odd and disconcerning problem. Just recently a page where I have 1 textbox and a buttoon has ceased to work.
When I look at the post coming into the PageLoad, the pageType is "POST", but the Page.IsPostBack is false!! and the textbox (which had content) is empty.
I have stripped all AJAX script out, so I have a very vanilla page (in a master page) being served.
The pages is
[Code].... [Code]....
The page is "POST", but isPostback is false[Code]....
