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 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?
View Replies View Relatedi have an aspx page. on that page there are three textboxes. when the controle is in any textbox and i press enter,the page is postback to server. i want that when i press enter the page does not postback to server. how should i do that?
and i want to know what is the javascrtipt event fired when ever enter pressed in asp:textbox.
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.
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"
