List controls not refreshing in UpdatePanels

I'm trying to figure out why when I click Remove on any listbox the postback doesn't refresh the listbox to show the change. I thought that every updatepanel refreshes. If this is so, then why isn't my listbox automatically reloading the updated list after I remove an item? I end up having to refresh the whole page manually in order to see any removed items from my listboxes

Hello,

How do you get the data into the listbox? Try this:
for example the list box inside this updatePanel

<asp:updatepanel id="CuentUpdatePanel" runat="server">
<contenttemplate>
<asp:listbox id="lbCuent" runat="server" width="214px" /><br />
</contenttemplate>
</asp:updatepanel>

After you click Remove, for sure you have to call a function right? In that function, also call: CuentUpdatePanel.Update()
This will update the UpdatePanel ... and if your list box uses a ObjectDataSource ... example below

<asp:updatepanel id="CuentUpdatePanel" runat="server">
<contenttemplate>
<asp:listbox id="lbCuent" runat="server" DataSourceID="GetListITems" width="214px" /><br />
</contenttemplate>
</asp:updatepanel>

then in your function, you do this: lbCuent.Databind();

Hope it helps ... by the way, next time don't bother post all of your HTML in here, too much, waste your time. =) just the part that you have problem is enough already ... and the code behind that is related to it ... Cheers

The problem is that I didn't rebind my listbox after whatever event (insert, delete, etc.)

I didn't even have to call the .Update() manually, it all works fine now after the obvious missing rebind of my listbox controls

Load different content pages in content place holder without refreshing the whole page usi

Hi,

I have built a ajax enabled website, where i have a master page which holds a content placeholder, and two content pages, where one is the home screen and another is a dashboard, a menu is placed in master page , by default home page is made to display, when the menu item dashboard is clicked , the the contentplace holder should load the dashboard page without postbacking the whole page, how to do that through ajax? Pleas help me.....

Its very urgent, I am stucked.....

hello.

i'd say that you cannot do that in your scenario. i'd refactor the site and transform the contents of the main page and the other page in user controls. then, i'd build only one page set its content to one of the user controls...

Hi Luis,

I am new in creating webapplication. I am not able to get what u'r saying.

Plese explin me in details, What is usercontrol ? How does it satisfy my needs?

Please help me. Give me an example, whre they have used user control .....

Thanks in advance

here's an old post that shows how you might change the user controls on an udpate panel:

http://msmvps.com/blogs/luisabreu/archive/2007/02/15/adding-controls-to-an-updatepanel-through-code.aspx

regarding the user control part, well, it's really the easiest way you have to develop a control. i think that if you go to the asp.net site, you'll be able to get lot of info from the quick starts

Loading data from popup to parent window without refreshing the parent window.

Hi all,

I have a requirement to pass data from a popup window to the parent window. There is an order entry screeen. The user has to select a customer before entering the order. On clicking the search customer button, a popup will open up where the user can do the search. The user will select a customer and the selected customer details should be passed back to the parent window without refreshing the parent window.

How can this be accomplished? Kindly help me as this is a very urgent requirement.

hello.-

not really an ajax question. lots of examples out there that show this. here's one:
