I am using TabContainer with some controls on each tab (asp: labels, text boxes). When redirecting to the page that contains the TabContainer, the tabs and their content loads as expected, but when there is a postback, and the page refreshes, the TabContainer UI changes - the font size of the labels gets bigger, the text boxes become bigger and their location changes a bit (not aligned as before), and the tab header is partially hidden. I am using IE7.
I dont know if this is relevant but in some of the text boxes i use edit mask extender as well for date. Also, I have used a table inside the TabContainer for layouting the controls.

i duno why, when i put a autopostback in my drop downlist, after the postback, my content HTML editor and the flash button all disappear.
i have put the enable view state = true. but it still happen.
I am an asp.net newbie and encountered problem with postback. I have created a web form and put some web controls and set their AutoPostBack property to True.
Some of the controls are listbox, checkbox. However, the SelectedIndexChanged and OnCheckChanged do not fire automatically when an item is selected from the listbox for example or when the checkbox is checked. I noticed that the commands I put in the SelectedIndexChanged and OnCheckChanged is only fired when a button is clicked.
e.g. The code below that sets the text of a label is being fired only when a button is clicked even if the autopostback property of the listbox is set to TRUE.
protected void ListBox1_SelectedIndexChanged(object sender, EventArgs e)
{
ListItem myItem = ListBox1.SelectedItem;
Label1.Text = myItem.Text;
}
Again, I would like the Label's text to change when an item is selected from the listbox and not only when a button is clicked.
What else could I be missing to make autopostback work?

I have a webform with multiple input textboxes. each box is used in computing somethings, and i am doing these calculations within the TextChanged event for each textbox...this way after the user enters each entry, all calculations requiring that data is performed. I have also set EnableViewState="true" and AutoPostBack="true" cause I am trying to have the textbox keep their data displaying on AutoPostBack. The form is not behaving the way I want it to...right now, if a user inputs data in one field and switches focus to the next, the previous box losses it's data. Is there a way i can get this behaving the right way? I basically just want all the controls to keep their data on AutoPostback.

I have a nut for a manager who changed my form and added _top so that I could redirect a response to a parent window, anyway, I have two .net forms and now he tells me I can't do any posting back on my child window. I have lots of .Net event callbacks that use autopostback on this child window. He told me he believes I can do all the necessary event code through his Javascript client-side scripting that he loves so dearly. I don't think he knows .NET very well even though he acts like he does. the microsoft server coding world and without replacing every object in my child window (there are many) with html and resorting to an html page (God help me Bill Gates I'm coming to get you) is there anyway I can have my events (onselectedindexchanged onclick ... ie) to call javascript functions without an autopostback on any of my controls ?

<asp:CheckBoxList ID="cblTest" runat="server" AutoPostBack="true"

How can I capture which control has triggered the autopostback event when it runs again in the Page_Load method.

I've got a server control that renders out a series of dropdownlist and a checkbox that all have autopostback set to true. When the control renders the onchange event binding is not written out!
Controls are defined as protected, named and added to the controls collection in OnInit, and rendered via RenderControl(writer). Page.requiresPostback is also set.
ANy ideas why this might be? I'm scratching my head.

I have on site three textbox controls, RequiredFieldValidator with each textbox and button (without any code). I have problem, when I set autopostback property of textbox controls to true. Regardless, that EnableClientScript sets to true or false, validation error dissapears - or show only few seconds. Helps only set CausesValidation property of textbox to true. And my question - if autopostback is set to true, should I set causesvalidation to true too to make proper validation process? Why it doesn't work?
View 7 RepliesI inherited a really weird ASP.NET application where every .aspx page is basically a WebControl that acts as a surface for every other control that page is supposed to render/display.
One such page has a DropDownList -- I wanted a very simple thing that people do every day, namely to cause a postback when user changes a selection in it. I thought all I had to was set dropDownList.AutoPostBack = true, but after the page is rendered, when I see the generated HTML, I notice that there is no "onchange = __doPostBack(...)" code for the dropdownlist. Consequently selection changes don't do anything. Before I spend too much time digging into this, is there something obvious I am missing?
I have an autopostback dropdown with a requiredfieldvalidator associated with it. If I click the submit button on the page without selecting an item from the dropdown, the validator will fire as expected. Then, if I select an item from the dropdown, the validator message goes away, but the postback does not occur. The postback only works if the validator has not fired first.Is this by design? How can I work around this so that the dropdown still does a postback when selecting an item after validator occurs?
