AJAX :: Updatepanel And Dropdownlist In A Masterpage?

Apr 26, 2010

firstly,i am going nuts with this problem. here it is:

i have a masterpage that contains a dynamically populated dropdownlist. i have autopostback =true and an onselectedindexchanged function. users user the dd to choose from a list of accounts that are available to them to edit/view. this portion works great. users pick an option and it postsback with the correct item. the item chosen gets set in the users profile so it defaults to it next time they log in.

now the problem arises on certain pages that use this masterpage. the child page has a timer, an updatepanel, and a gridview inside the updatepanel. the timer tick event fires and calls databind for the gridview. this all works great---EXCEPT, if the timer ticks while i am looking through items in the dropdownlist, the gridview updates, but also THE ONSELECTEDINDEXCHANGED event fires for the dd, even though i haven't actually clicked the dd to change it. just clicked it to make the dropdown active to
see its items. once the timer ticks, it automatically selects the dd item that i happen to be on... it is as if the updatepanel is causing a full page refresh.

i can use the timer_tick event to set label values, and it works like an update panel should....only updating the content inside the updatepanel. it is only when i am trying to choose an item from the dd in the masterpage that a full postback occurs. this creates a problem, because whatever item in the dd i happen to be on when the timer ticks is the one that gets selected. the selectedindexchaged event is supposed to call a full postback, but not the updatepanelupdate caused from the timer tick. my dropdownlist in masterpage

AJAX :: How To Set MasterPage Only Render ContentPage And Control Inside UpdatePanel

Mar 27, 2011

I have a DateTime in my MasterPage.aspx that is outside of UpdatePanel1. There are two Hyperlink controls inside UpadatePanel1 to navigate or to move to the other pages. Full code of MasterPage.aspx is below.


If the user clicks Hyperlink to navigate or move to the other page, the DateTime will change. It means that my MasterPage.aspx render the whole page when the user clicks Hyperlink. I do not want this behavior. I want my MasterPage.aspx only render the ContentPage and the
Hyperlink inside UpadtePanel1. Controls outside UpadtePanel1 like DateTime should not be rendered again. Please advise the code to achieve my example goal.

AJAX :: Updatepanel Not Working

Feb 11, 2011

I have a simple aspx page created using VS2010, having a master and a content page. I have added the ScriptManager from AJAXControlToolkit on the master page and an update panel on the content page. Essentially clicking a link button should display a popup box through the PopupControlExtender. The issue I am facing is that eventhough I have AJAXified the page, clicking the Linkbutton (named lnkFlag) doesn't do partial update, instead it makes full page postback. This could be infered by the fact that both the lblOut and lblIn labels are updated with the server's time. If there is a partial page postback then lblOut should not be updated, since it is outside the UpdatePanel.

ScriptManager in the masterpage:

Validation In Ajax Updatepanel - Not Working

Mar 15, 2010

I have a panel (say, panel1) inside another panel (say, outer-panel)….The panel1 is visible only when a checkbox is checked in the outer-panel. I am using ajax update panel to do this.
Now I have many text boxes in the panel1. I have to put a validation on all the boxes.

I tried to test this by putting validation on 2 boxes and this works fine on my local machine. When I put the same logic on the server, it does not. Of course the page on my local machine has fewer text boxes compared to the page on server. But I do not understand why the same logic works on my local machine and does not work on the server. I did try to put a validation group, but of no use.The page on the sever is a very long one and also it has a captcha control….. when ever I try not to enter text in one the text boxes which has validation and then hit submit…it redirects me to another page with out prompting for the validation error.

AJAX :: Linkbuttons In Updatepanel Not Working SOS

Jan 27, 2010

I am building a website using ASP.net ajax. there are 3 <asp:panel> controls in the page and each contains a number of dynamic linkbuttons. these panels are contained in a <asp:updatepanel> control the page_load event fills out the first panel with linkbuttons and assigns cooresponding commandName commandArgument for them, that works. then the first panel's linkbuttons triggers the command and fill out the second panel with linkbuttons, that works too. then the seond panel's linkbuttons are supposed to fill out the third panel with linkbuttons, but that doesn't work anymore, and it seems like doing the page_load event again and filling out the first panel and the second panel's linkbuttons disppear, just like the first time the page is loaded.

Need Updatepanel And Scriptmanager Get AJAX Working?

Dec 13, 2010

I'm finding that the scriptmanager and the updatepanel and basic implementations of AJAX for ASP.NET. I'm just wondering whether these were required to use AJAX and partial page update and referencing handlers such as button1_click on the server code page ?

Also if i can ask another question, I'm also wanting to know whether the updatepanel can support feed-in like facebook ? What I'm wanting to do is have something that updates the screen (like the update panel), and items within this panel contains links. When the user clicks on the link it shows a modal div, giving the user options to do some updates. Once the user clicks submit, then this makes a call to the server to update the details then also update the panel. Within the panel I also want to move some of the div elements using javascript (causing the drag and drops to save to the database).

AJAX :: UpdateProgress With A Dummy Updatepanel Not Working?

Aug 17, 2010

I have a Submit button and some functionality like updating DB and fetching next page in the button click event. This process takes a long time and I want to display a message saying "Progress...." right after clicking the botton. I want to do the same in 20 other pages. So, best way to do it wd be to put the modalpopup MPE or an Updateprogress in a usercontrol or in master page. I first tried putting both of these on the page itself to test and see and neither worked.

I tried using Update progress control with a dummy updatepanel and giving the Submit button as Asyntrigger to the dummy updatepanel. I have also tried using MPE but it didnt work either. Below is an example of what i did..

<asp:UpdatePanel ID="UpdatePanel1" runat=server><contenttemplate><triggers><asyntrigger ID= "Submit"> /> /> />
<asp:updateprogress ID="Progress1" unat=server AssociatedUpdatePanelID="UpdatePanel1"><Progresstemplate>Progress.... />/>
<asp:button ID= "Submit" runat=server >

I have nothing for updateprogress in code behind. Am i missing or doing somethign wrong here?

<td><asp:Label ID="Label5" runat="server" Text="Sub-Department:"></asp:Label></td>
