Say I have a textbox (autopostback=true) and a button. I enter a new value in the textbox then - without clicking anywhere else first - I click the button. The box's text isn't changed prior to the button's click so the new data in the box isn't evaluated at the server. The user has to click the button twice.
I would like to change this without any scripts on the client that will be rejected by security setting in today's browsers.
how can i check if page was initialiy loaded or if it's postback?
View Replies View RelatedI always see the term "postback" from ASP book, but I am not sure if I fully understand the meaning. Here's my understanding so far, please correct me if any mistakes. here's a typical html form:
<form action="process.asp" method="post">
'GUI code
</form>
"postback" action happens when the user click the submit button, that means it will invoke "process.asp" is the above code. In ASP.NET, if the web control has set AutoPostBack property to True, that means when there is any events on the web control, it will invoke "process.asp", just like the user click the submit button.
I am getting to a stage with my site that i have so many entries in the database that i am thinking of adding an a-z at the top of the page. Thinking aboout this further and how it may work i thought that this would use a post back method where it passess for example the letter "a" in the link (Am i on the right lines?

I want to know if the PostBack concept applies to HTML web-based forms, regardless of what programming technologies we use: For example, ASP, ASP.NET, Java, CGI, etc
PostBack means to send the HTML form to the web server Since most of the time I heard this term in ASP.NET circle, thats why I raise this question.
Can I make the screen state where it is after a control is auto postback? And how?

Want to check the value of an inputbox against a SQL Server database to prevent a duplicate record being entered.
This is an existing project, and the way they implemented it before was to post to a 2nd ASP page, run the ASP code to check the value, then redirect back to the 1st page if the value was found to be "already used".
There has to be a better way. Is it to use "Postback"?
Using a VB aspx web form I have a TextBox web control and a DropDown List web control that both AutoPostBack to the server when their state has changed. When the user is in the TextBox, changes the text and using the mouse selects the drop down list control, the view state is destroyed and a blank screen results.
When the user has changed the text in the text box and moves focus off the text box using the tab ke the page does the postback with no problems, but when the focus is changed by using the mouse to click on the dropDownList control it to tries to do a postback at the same time.
Am trying to restrict user from entering non ASCII character in the text area. Say if the user entered non ASCII character then on the form post back it should show them the message like:
"non ASCII character between the word1+word2"
I am building an asp form with various elements
<td tabindex=[x]>blablabla</td>
Where the [x] is the order I want, so far so good and using the tab key
provides the desired results however...
When I *click* on one of the elements the tab order is not updated and so the
next tab key jumps to wherever tabbing left off.
Is there a way to use onfocus() or something to update the tab order so the
next tab will focus on the next element after the *clicked* element?

I get an error message saying that the textbox is null or not an object.
I have a text box, when the page loads i want this text box to have focus. Ive got this right and ok, BUT, because this has text inside it it sets the focus at the begining of the text. Is there a way so that it will set focus at the end of the text value?
View Replies View RelatedI have a SSN Field which include 3 text boxes. How do I move the focus from one box to another as soon as user enter the max characters in the text box.

How do I make a form's text box focused on page load? I have a page that loads one text box for a user to enter their zipcode and then press search. How do I get the cursor to be in the box when the page loads. I do not have access to the Code:

Only what's between the body tags. Maybe a javascript out there?

View Replies View RelatedIs there an ASP equivalent to Javascript's '...focus.();' that returns focus to a form field? I want to accept input from a user on a form.This input is to be databased and also unique. I want to check the user's input against what already exists in the database. If the input already exists.
I want to generate a pop up dialog box ala javascript and then when it's acknowledged, return focus to the form field.

I have a form which has 1 textbox in it. When the user enters a number, and tabs, it submits the form and the textbox disappears and the name of the person that the ID corresponds to is displayed (filters recordset, returns name).
The problem I have is that this is the first textbox on the page, and when the user tabs, the tab order gets funky and the user has to click on the next textbox. This is unacceptable to my data entry people, as they are used to tabbing everywhere. Does anyone have any ideas?
I have 3 asp pages.
A link in the first one creates a popup window.
A link in the popup window opens a page with 2 frames in it, top and bottom.
Now, I have a link in bottom frame of this page, which, when clicked , should give focus to the existing popup window.
When creating the popup window, I used a reference to it like...
