I want to create a page with 4 UpdatePainels but when this page loads in the browser only the first UpdatePanel will load and others will be hidden. This others will be load when I click on the buttons located on the first UpdatePanel. My intention is that the page doesn't load entirely at once, just when I click on the buttons. How can I do this?
View 2 RepliesIn my page without using updatepanel page open firsttime it fires only single time, after using updatepanel page load fires twice firsttime page open.. how to solve it.
View 1 RepliesControl ctrl = new Control();
this.PlaceHolder1.Controls.Clear();
ctrl = Page.LoadControl("uc1.ascx");
ctrl.ID = "DynamicCtrl";
this.PlaceHolder1.Controls.Add(ctrl);
instead of using a control to load can we load a page .. like example.aspx
page mypage=new page();
mypage= Page.Load("example.aspx");
how to do this. as i am getting the erro

I have a piece of inline java script which is within an AJAX updatepanel. The code works perfectly on 1st load but not when the updatepanel is updated.
My script is as follows:
<script type="text/javascript">
var flashvars = {};
flashvars.galleryURL = "Photo_gallary/personal.xml";
var params = {};
params.bgcolor = "000000";
params.allowfullscreen = true;
params.allowscriptaccess = "always";
swfobject.embedSWF("Photo_gallary/simpleviewer.swf", "flashContent", "100%", "250", "9.0.124", false, flashvars, params);
</script>
As this is not a function how do I put it in the ScriptManager.RegisterStartupScript - which is I think what i have missing.
UpdatePanel Won't Properly Trigger If Time Passes?
View 4 RepliesI cannot use asyncFileUpload as it has too many restrictions which doesn't meet our requirement.
I'm able to add a updatepanel trigger to force the Button1 to perform a postback. after the file uploaded, I need to use a timer to do different tasks and return messages back to client with the timer. That is all fine.
However, when one upload is finished. I try to do it again. The FileUpload1.HasFile is "false". I don't know why. if I remove the timer, at the second time, the HasFile is "true". I think there must be something in the timer and disable the Button1's postback.

View 2 RepliesI have 2-3 update panel in my page and i don't want to load chart every time when my page loads or button clicks etc. I put that in update panel with triggers means only some clicks should loads chart. but that chart gets loaded everytime. how to stop that from loading
View 2 RepliesI have a page with two updatepanels both which have thier triggers outside of the panels themselves - I am setting the triggers using in the pageload event. This is how it works - there is a repeater that holds a list of links which gets set when the page loads (this is outside of the update panel). The first udpatepanel has a trigger set to the itemcommand of this list of links - it then goes out and gets the sub links and fills a repeater that is located in the update panel. - so forgetting all about the second update panel on the page... If I set the panels updateMode="conditional" then it doesn't render till I click the link twice. If I put a breakpoint in the code I can clearly see that the code is executing and that there is no error but again... Nothing renders
- I click the link again it renders. If I take out the UpdateMode="conditional" statement all is well... But I don't want that cause I two update panels on the page.
The second one also has sort of the same problem - The trigger I have set for it the ItemCommand for the repeater in update panel one... when I click one of the linkButton's in the first updatepanel sure enougn I see the code execute return my results and all seems well however there is nothing rendered on the page. BUT!!! When I click one of the main links on top (remember these are trigger for updatepanel one) my second repeater inside of updatepanel2 is shows up on the page.
What is causing the partial postback not to render anything?
I know this is confusing so I hope I explained myself well enough. I will just post the ASPX so you can see how I am setting this up - I don't think you need to see the code behind... If anyone does then I will post it.
Again - all this is to with the updateMode - when I remove it (as I did in this code sample) it works and renders however I don't want both updatePanel to get updated at the same time.

I am working on a ASP.NET 2.0 application. It is hosted on IIS 6 on Windows 2003 server.
Few pages have jpeg images (around 50 images and 50 KB each). It takes long time to load the page for the first time. But when i open the same page for the second or third time it is faster.
why does a web page take long time to load for the first time?
Is it cached somewhere when it loads for the first time? Do we have any control over it?
Issue:
As my pages are taking time to load first time.
So user has to wait till full page gets loaded and thats irritating . Was this the reason MVC was evolved?
Solution :Should i use partial rendering on all pages including home page, and all forms getting called from home page.
So even if half page is loaded thats less frustrating
For Partial rendering what i plan is : i will put Scriptmanager with Enable partial renderingand update panel for half part of page.
So that user dont have to wait for full page to load.
Is my plan correct? Problem is i cannot regenerate page load issue every time.
I am currently using a asp.net 2.0 with visual studio 2005.
I am trying to build a web application using ajax.
but when I drag the ajax updatepanel on asp.net page it is not resizable,so how should i put other controls on it?
i am using a TabContainer and at each TabPanel i have embed an UpdatePanel in order to update each tab alone.
this is my code:

the problem is that it makes several seconds to update each tab (the same time for every tab) and i asume that this is happening because it updates all the TabContainer and not the selected Tab.
I have two updatepanels on my site (upanProfileSearch and upanMemberList). When I hit the button in the upanProfileSearch it should bind the Data Items in the gridview in upanMemberList and here make a RowFilter on the text in upanProfileSearch. When I make a run to curser, I can see, it happens. It makes a RowFilter. but it doesn't update the gridview. Can anyone tell me why it doesn't update? I have UpdateMode="Always" and RenderMode="inline" on both UpdatePanels.

I have a dropdownlist, that causes a postback. On the SelectedIndexChanged event, is it possible to force a placeholder that is within a different UpdatePanel to change it's visibility?
For example, when the SelectedItem.Value of DropDownList1 is "1" then show Placeholder1, otherwise hide it.
What I am most interested in is how to configure the UpdatePanels to allow this.

I have a web user control with one updatepanel (pnlUpdate_2), some controls and one apply button. I display the web user control as a modalpopup in my default page. In my default page i have an updatepanel (pnlUpdate_1) with a gridview and I modify that gridview with the apply button of the web user control. The web user control is for made a custom search of the gridview data. I have a problem with both updatepanels. If I set the updatemode as always in one of them (pnlUpdate_1) and the other as conditional (pnlUpdate_2), the pnlUpdate_1 make a postback in the pnlUpdate_2; I'm not an expert on this but I think that's why the pnlUpdate_2 disappear and reappear after postback of some controls in that updatepanel (not the apply button, it close the modal after postback). I try all the combinations and the problem persists. So I put both updatepanels as conditional and in some way it works; now the problem is that when I click the apply button in pnlUpdate_2 to modify the gridview in pnlUpdate_1 the pnlUpdate_1 not made the postback I get the pnlUpdate_2 postback when I use some control inside the pnlUpdate_1.
How can I postback the pnlUpdate1 from pnlUpdate_2 with the apply button?
I have a User control(ascx) that has an Update panel. When the page is getting loaded on some condition i want it to hide few of its controls of the UpdatePanel. Is it possible?
View 1 RepliesI have a custom Panel with attribute Designer(typeof(xxxMainPanelEditor), typeof(System.Web.UI.Design.WebControls.PanelContainerDesigner)). The child controls of this custom Panel Control at design time can see all the exposed properties that I want to share from the Parent (no problem here).
However, if I place controls on an UpdatePanel, these child controls cannot see the parent container but instead, it immediately sees the form/page or DesignerHost. The problem is the same even if I put Panel on the UpdatePanel and vise versa.
Is there a way to manage controls inside an update panel? For me, this behavior is like saying that UpdatePanel is not container based during design time?
