Configuration :: Partial Page Refresh Using UpdatePanel Inside A WizardControl?
Oct 14, 2010
I've implemented a Wizard in which most steps are UserControls. One of these steps contains a DropDownList and a RadioButtonList. Depending on the item selected in the DropDownList, some items in the adioButtonList are disabled or enabled via a callback. This works fine.
Then I added a ToolkitScriptManager to the page (EnablePartialRendering="true") and wrapped the controls in this particular step in an UpdatePanel's ContentTemplate. Running inside of VS2008, the appropriate radio buttons are disabled or enabled as expected in response to changes in the DropDownList without a full page refresh. It feels much more response and looks slick.
Then I deploy to the test server and suddenly the partial-page refresh is gone, the whole page is redrawing as though the script manager and UpdatePanel hadn't been added.
I've tried several variations on this, always with the same result. For instance - I moved the DropDownList outside of the updatePanel and added an AsyncPostbackTrigger for the DropDown's SelectedIndexChange event. No change - works in VS2008 but not on the server. - I added ChildrenAsTriggers="false" UpdateMode="Conditional" to the UpdatePanel, both with the DropDown inside the UpdatePanel and outside the UpdatePanel. No change - works in VS2008 but not on the server.

I want to make auto partial page refresh in asp.net. There is UpdatePanel but it sends too much data. So I've found that I can make a webservice and call it by the JavaScript code. But I don't know how to call webservice automatic. There are many examples showing how to call webservice by the button click event:

How to do this by the interval? Am I going in good direction?

I have a linkbutton inside a updatepanel and when the update panel does a partial page rendering, the linkbutton disappears.
<asp:UpdatePanel ID="up" runat="server" ChildrenAsTriggers="true" UpdateMode="Conditional">
<ContentTemplate>
<asp:DropDownList ID="drp" runat="server" AutoPostBack="true" CausesValidation="true">
<asp:ListItem Text="" Value="" />
<asp:ListItem Text="a" Value="a" />
<asp:ListItem Text="b" Value="b" />
<asp:ListItem Text="c" Value="c" />
</asp:DropDownList>
<asp:LinkButton ID="link" Text="abc" runat="server" />
</ContentTemplate>
I think that is because the link button is rendered using a script and that script is not run after the post back.

I am using AJAX TabContainer control with following settings. When I change a tab the postback happens and whole page refreshes. Because AutoPostBack="true"> . To AJAxify the behavior, I added UpdatePanel around it but still the page is refreshing. The control need to go to server because user controls contains some grids which need to be populated.
<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
<asp:UpdatePanel ID="upTLTop" runat="server" UpdateMode="Conditional">
<ContentTemplate>

How can I disable the page refresh and at the same time server side operation happens in this case?

[URL] .... am using this functionality in my project and it is working very fine but i am facing very strange issue while using this.
The above functionality is not working when we place dropdownlist and textbox inside updatePanel and ModalPopupExtender
The .aspx page where i am using ModalpopupExtender and UpdatePanel for DropDownList and Textbox is below
<%-- *************************** MODAL POPUP EXTENDER ***************************************************** --%>
<asp:HiddenField ID="HiddenField3" runat="server" />
<asp:HiddenField ID="HiddenField4" runat="server" />
<cc1:ModalPopupExtender ID="ModalPopupExtender1" runat="server" PopupControlID="Div6" TargetControlID="HiddenField3"
BackgroundCssClass="modalBackground" CancelControlID="bclosemodalpopup" >
</cc1:ModalPopupExtender>
[Code] ....
The above code is not working with UpdatePanel but it is working if we remove DropdownList and Textbox from updatepanel.
The javascript code which i am using is below
<script type = "text/javascript">
var ddlText, ddlValue, ddl, lblMesg;
function CacheItems() {
ddlText = new Array();

This upload is working. But why the page is getting refreshed? this is not partial post back and instead it 's full post back. i have read the articles for the fileuplaod with issue inside the update panel. is there any way to achieve this asynchronous upload on button click?
I don't want to use the Ajaxtoolkit Asyncupload because that will upload (Ref : [URL] ....] the moment when we seelct the file itself which i don't want to do that. i need to do on the button click event.

I have a simple form (textbox, submit button) which is wrapped in an update panel.
[Code]....
I type some text in the textbox, click submit, then the server creates a database record and returns an object, which has properties like ID, Name, URL, Blah, etc. These are the values that the script requires.
So if i were to call a web service from the client-code, in order to get the values that were just created, i would need to do some hacks (get last record modified that has the value of the textbox). Not ideal, and neither is two AJAX calls for one form post. (update panel postback, then web service call).

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
Below is full code MyMasterPage.aspx.[Code]....

I am having problems selecting the text within a TextBox in an UpdatePanel in IE 8. Consider a very simple page that contains a single UpdatePanel. Within that UpdatePanel there are two Web controls:
A DropDownList with three statically-defined list items, whose AutoPostBack property is set to True, and
A TextBox Web control
The DropDownList has a server-side event handler for its SelectedIndexChanged event, and in that event handler there's two lines of code:

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:
[Code]....
On Selected Index Change code for each
For the First:
[Code]....
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()

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.
Everything is working below in the sample code. However, UpdateProgress will not display unless the button is actually clicked by the user. In real production scenario I would hide the button. To invoke the immediate UpdatePanel refresh I trigger the click via Javascript. I have also tried "__DoPostBack" without success.

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.
