I am developing an asp.net web application and stand on jQuery plug-ins for any aspects of my Interface. But unfortunately I have to use AJAX only for its UpdatePanel to enable partial rendering. Is there any way to use jQuery for partial rendering and act such an UpdatePanel?
View 2 RepliesHere's my situation:I've got a parent UpdatePanel (with ChildrenAsTriggers set to false and UpdateMode set to conditional) that contains a webpartzone which loads webparts with user controls inside them at runtime. Both the parent UpdatePanel and the child UpdatePanel (also set to ChildrenAsTriggers=false and UpdateMode=Conditional) obviously have triggers set up that are relevant to them.
The problem is that whenever the parent UpdatePanel fires an asynchronous postback, the child UpdatePanel in my user control gets fired off as well thereby causing my user control to be re-rendered. I don't want this to happen. Outside of initially loading the user control, I want that user control to only get updated/rendered again when a trigger inside itself is fired,not when the parent (outer framework) fires off one of its triggers. A ParentAsTrigger property (set to "false") for the child UpdatePanel would be perfect if it existed.
Note that I've tried eliminating the child UpdatePanel inside the user control and then loading the triggers for those controls to the parent UpdatePanel at runtime, but that doesn't work because the user control is being invoked within CreateChildControls() -- I get an exception when I attempt to do that.
If I set up a repeater that has LinkButton controls, an UpdatePanel works great. If I add child elements to the LinkButton,such as SPAN, the UpdatePanel stops working as expected. If you click on the area of the LinkButton everything still works, but if you click on the area of the SPAN inside of the LinkButton, you get a full PostBack.I've tried setting ChildrenAsTriggers to true and a few hundred other things. Nothing seems to work. I think the UpdatePanel sees that the "click" event happened on the SPAN and doesn't know to capture it for an async postback.

I'm building dynamically a series of ImageButton controls, and I want to assign them a hyperlink for downloading files.So say you got a dropdownlist of 3 items 1,2 and 3, if you select 1 it creates one imagebutton and pointrs to fileA, if you select 2 it creates two imagebuttons and the first one points to fileA and the second one to fileB and so on...Everything is wrapped in an UpdatePanel to avoid postbacks.I have a problem binding the download link in the ImageButton.navigateurl, and then downloading it. I don't know how to do it...

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.

In my application, I am using different user control for different tasks. I used an update panel to load user controls with ajax. It is working fine. I am using some other update panels inside the user controls. My problem is, the inner update panel(UpdatePanel placed inside the user control) is not working properly.
View 1 RepliesI 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.
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.

my code is very simple. I have one updatepanel, it has one lable and one dropdownlist. everytime, dropdownlist index changed. Label shows selected value. if you select any options besides the first one, it works. if you go back to the first option, then event will not get fired. spending hrs searching on google, couldn't find anything useful.
here's my code

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).
I have MP inside MP but when i am using UpdatePanel not working. No ajax, page is reloading like before...

I have one button and one textbox inside a updatepanel. On button click I am adding an alert script. But when I use the ViewSource by right clicking on the page, then the alert script is not generated.
[Code]....
[Code]....
But if I remove the the UpdatePanel then the script is generated and the alert message is displayed. What should I do to register the script when using updatepanel.
I know that there are hundreds of posts out there on this problem, but I have tried everything (I think) and I still have not resolved it. If I remove the update panel everything works fine.
I've tried :
[Code]....
And every other variation I can think of.
Here's the ClientSide code:
[Code]....
And here's the Server Side code:
[Code]....
<script type="text/javascript">
$(document).ready(function () {
$(".autotab").keyup(function () {
if ($(this).attr("maxlength") == $(this).val().length) {
var index = $(".autotab").index(this);
var item = $($(".autotab")[++index]);
if (item.length > 0)
item.focus();
}
});
});
</script>
the above autotab code not working if required textboxes in updatepanel. how to solve it.

View 2 Replies I have a ReportViewer with drillthrough function report and it takes 3 mins to run the report on buttonclick.So I have enclosed ReportViewer with AJAX update panel and give a wait.gif ProgressTemplate.
After this change onbuttonclick now the wait gif appears and then the report displayed as desired after 3 mins. However, now the drilldown function of the report is not working anymore and view error it says "ClientReportxaxsaacscdcsdci678686 is not defined.
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?
We have an updatepanel in our site and there are a number of linkbuttons in it. Please note that the site works fine in all browsers without proxy the proxy changes the url from for instance [URL] to 0-[URL] it also works fine in all browsers but IE the issue is that under proxy and in IE8, it gives an error when clicking one of the linkbuttons, the error message is "Webpage error details User Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; Trident/4.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; Tablet PC 2.0; InfoPath.1; .NET4.0C; .NET4.0E) Timestamp: Sun, 13 Mar 2011 20:38:58 UTC

I have no idea what goes wrong here, it seems that IE can't parse the response?

This is all going fine, But now on Panel2, i am unable to click on the buttons IF I remove the updatePanel: UpdatePanelPages from my masterpage then all is working fine ?
The following is not working (does a full postback). Note: HTML tags inside updatepanel. We can' t have HTML tags inside updatepanel? If so, what's the work around?
<asp:UpdatePanel ID="UpdatePanel2" runat="server">
<ContentTemplate>
<td><asp:DropDownList ID="ddlDEPT_ID" runat="server" AutoPostBack="true"></asp:DropDownList></td>
<td><asp:Label ID="Label5" runat="server" Text="Sub-Department:"></asp:Label></td>
<td><asp:DropDownList ID="ddlSUB_DEPT_ID" runat="server"></asp:DropDownList></td>
</ContentTemplate>
</asp:UpdatePanel>
The following works fine. AJAX in action.
<asp:UpdatePanel ID="UpdatePanel2" runat="server">
<ContentTemplate>
<asp:DropDownList ID="ddlDEPT_ID" runat="server" Width="200px" AutoPostBack="true"></asp:DropDownList>
<asp:Label ID="Label5" runat="server" Text="Sub-Department:"></asp:Label>
<asp:DropDownList ID="ddlSUB_DEPT_ID" runat="server" Width="200px"></asp:DropDownList>
</ContentTemplate>
