AJAX :: Refresh UpdatePanel At Content Page Asynchronously From Master Page?
Mar 5, 2011
I have master page
MyMasterPage.aspx and content page MyDefault.aspx.
MyMasterPage.aspx has one input button [value="Menu-1"]. When user click the button, the button will pass value "Menu-1" into
TextBox1Default1 at content page MyDefault.aspx, and then refresh
UpdatePanelDefault1 at content page MyDefault.aspx asynchronously.
My problem is the post back is full post back when refreshing UpdatePanelDefault1. I would like asynchronously post back during refreshing UpdatePanelDefault1. copy the full code MyMasterPage.aspx and MyDefault.aspx below, and then paste / overwrite it into your blank aspx page for testing. I am using VS 2008
I have an updatepanel on my master page that just updates the database every 30 seconds, what is happening is that everytime it is fired, it will refresh everything on the page_load of the content page that are not under ispostback = false. to disable such a thing just for this specific updatepanel?
</table> </ContentTemplate> </asp:UpdatePanel> <asp:UpdateProgress runat="server" ID="ugLN" AssociatedUpdatePanelID="upLN"> <ProgressTemplate>Image here for showing the progress bar...</ProgressTemplate> </asp:UpdateProgress>
I am writing a web application which consists of a master page (header / menus) which does not change and content pages. When I do something like click on a button it causes a post back which is correct but this redraws the whole screen and becomes annoying because every post back and the whole screen flickers.
I have 2 ddls (cascading that does not use the AJAX cascading ddl) within an updatepanel within an EditTemplate field in a DetailsView. Changing the first ddl causes a full page refresh (this is the problem I am trying to overcome), but changing the second ddl does not. The second ddl is set to autopostback as well because of other logic (if user selects value "Add" a modal pops up to add a new option to the database).
Now the first, does a call out to a class to handle setting the list of values for the second...that is the only difference I can tell between the two, but I wouldn't think that would cause the issue because it is within an updatepanel.
Here's the code:
On Selected Index Change code for each
For the First:
For the Second:
Protected Sub ddlModel_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Dim ddlModel As DropDownList = dtlBikes.FindControl("ddlModel") Dim ddlMfg As DropDownList = dtlBikes.FindControl("ddlMfg") If ddlModel.SelectedValue = "Add" Then 'Add New Record txtDDLName.Value = "ddlModel" txtDtlsViewName.Value = "dtlBikes" txtItemType.Value = "BikeModel" txtParentID.Value = ddlMfg.SelectedValue txtNewItem.Text = "" txtNewItem.Focus() lblNewItem.Text = "Enter New Model:" modInsertItem.Show() End If End Sub
The following is an edited version Let me describe what I have observed and I hope some Ajax guru can shed some light on this. The master page has a timer (Timer1) and a content page also has a timer (Timer2). When Timer1's interval is shorter than Timer2, Timer1 works and Timer2 does not (i.e. Timer1's Tick handler is called periodically, but Timer2's tick handler is never called). If Timer2's inerval is shorter, it seems Timer1's handler is invoked by Timer2(i.e. Timer1's interval appears to be shortened to exactly the same as Timer2). Both of these timer controls are in their separate UpdatePanels.
I have seen this discussed in number of topics, but so far nothing to address my specific issue. I want to display the page the client, and then trigger an updatepanel refresh that will populate with data that takes 3-4 seconds to load (the rest of the page loads very fast). At the same time I want to display "...Loading..." text using UpdateProgress control.

I got strange behaviour here. My environment is VS.Net 2008 Team server and I tried to use updatepanel but failed.
When I clicked the button, I expect Label3 inside updatepanel to be updated and Label2 remained the same, AND of course without page refreshing flick. But the result is page is completed refreshed and both labels are updeted.
In my master page i have login pop with the help of ajaxModalPopupExtenderControl. Code for that is.
and now in my Home aspx page i have i search dialogue as popup. and code for that is.
and to make this as popup i have used jquery in my master page. and code is
NOW the peoblem is that when i click on <li> to make the search dialogue popup then it works find....but as soon as i click on the login button to make the login pop and close the login pop then that on click of the <li> the search button doesn't pop up the search button.
and the URl becomes http://localhost:20360/Home.aspx#dialog
and before click of the login button Url use to be http://localhost:20360/Home.asp when i use to click on <li>.
what could be the reson.?
when refresh the page the it works fine again...but after the click of the login button in master page that <li> click doesn't popup the search panel.
how to refresh particular usercontrol in the master page?after clicking some event on particular usercontrol i just need particular section on the page to be refresh instead on whole master page.explain me now to work in ajax to do reflesh as i am new in ajax i would be thankfull if explain me in detail.
I tried to do some think like following in usercontrol page but doesn't work.
I got an updatepanel which contains a normal panel on MasterPage. The updatepanel does not contain content place holder. On the content page, I have to add triggers to updatepanel for buttons that are dynamically created on "page_load" event. The problem is that, since the page_load event of content page is being called before master page's page_load event, UpdatePanel is not being created. So that, whenever i try to add triggers in page_load event of content page, i got an error like "A control with ID 'ctl00$editableContent$ctl42' could not be found for the trigger in UpdatePanel 'up1'."
The code below is for adding triggers to updatepanel for buttons.
MasterClass master = (MasterClass)Page.Master; AsyncPostBackTrigger trig = new AsyncPostBackTrigger(); [code]....
I have the same problem as [URL] However, the solution doesn't work for me since I'm using .Net 4.0 and xhtmlConformance is not there from start.
Basically, using a master page, the RadioButtonList still do the whole page postback even it's in the UpdatePanel. When I put the exact same code in a standalone page without a master page, it works as expected.
