I put the following javascript code inline but it doesn't trigger after the updatepanel is done with its postback:
function EndRequestHandler(sender, args) { alert("this should work"); }
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler);
[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" />

BackgroundCssClass="modalBackground" CancelControlID="bclosemodalpopup" >
</cc1:ModalPopupExtender>

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();

View 2 RepliesHow do i run a javascript event after a postback within an updatepanel
View 3 RepliesI want a Javascript function to be called automatically after the UpdatePanel has finished updating its contents. I don't want to use:
Sys.WebForms.PageRequestManager.getInstance().add_endRequest
and then call a JS function. This is because I have more than one update panels and I'll have to write all the condions to check which UpdatePanel was actually called and then do something. Can something be done using Triggers in UpdatePanel. Kindly let me know how this can be done.
It would be great of you could post a sample code too.
I can retrieve with JavaScript above the ASP.NET Updatepanel had made a asynchronous postback ?
View 1 RepliesI have a web form with textbox and button. I want after "ENTER" key click on textbox postbak form.I am using next code:
onkeypress=" if(event.keyCode==13)
{ alert(2);
WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions('ctl00$ContentPlaceHolder1$btnSearch', '', true, '', '', false, false));
alert(2);
return false;}
where WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions('ctl00$ContentPlaceHolder1$btnSearch', '', true, '', '', false, false));
is javascript code for button event onclick.I get two alerts, but postback doesnot happen.
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).
Basically I want to get some javascript to be sent back to the client and executed from a postback inside an UpdatePanel. Furthermore this is inside of a reusable WebControl. I've tried
this.Page.ClientScript.RegisterStartupScript and this.Page.ClientScript.RegisterClientScriptBlock but Firebug shows that those scripts aren't sent back in the postback's response.
I also tried straight up writing a <script> tag inside the control's main div in the Render method, which does get sent back but isn't executed. I got a hacky solution working, but ideally looking for a cleaner solution. The hack is to add a 1x1 pixel img with width/height set to 0 and use that for an onload event to execute the script and that works, but it seems like there has to be a cleaner way to do this.
My javascript that scroll down the page.
function SetScrollEvent() { window.scrollTo(0, document.body.scrollHeight);}
I update update panel from server side like below.
protected void rptList_ItemCommand(object source, RepeaterCommandEventArgs e){

//Button bt = e.Item.FindControl("Button2") as Button;if (e.CommandName == "myclickevent"){

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 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?
iam using the Jquery Uframe with asp.net project.Iam getting a postback problem here.
In side the uframe ,button control getting postback the page even the client side method call also.
i tried with the Html button Control also by setting the type="submit" ,iam facing the same problem.
And I got very limited reference about the uframe(codeflex,codeProject).
I have an ActiveX object which extends some functions. I have a web page that loads the ActiveX object and calls its methods in Javascript. The ActiveX object has two method; the problem is that Javascript can successfully call one of them but fails to call the other; citing Object doesn't support this property or method which is nonsense because I made a VB6.0 application that successfully calls this other method, so the two functions are indeed extended correctly and performing their job. And yes, the Internet Explorer security zones are all set and everything, as I wrote above the javascript code can call one method but refuses to call the other.

What this problem? What solution for it?
In a page contains two UpdatePanels, How can I know which UpdatePanel causes the partial PostBack ?
I mean in the Page_Load event handler.
This is my code:
[Code]....
When I click a button that causes a postback on the UpdatePanel it calls the tinyMCE.triggerSave().
It reloads the panel and the editor show up again, but when I try to call tinyMCE.triggerSave() the second time I get the following error:
g.win.document is null
I though it was getting the old instance, but I'm also removing the control (tinyMCE.execCommand('mceRemoveControl',false,'Editor');) after I call the save. Even so it still crashes the second time.
I need to intercept server callback after udate panel async post back and determine which panel initiated the request. The code is pretty simple:
Sys.WebForms.PageRequestManager.getInstance().add_pageLoaded(InterceptUpdateCallback);
function InterceptUpdateCallback(sender, args)
{
var updatedPanels = args.get_panelsUpdated();
for (idx = 0; idx < updatedPanels.length; idx++) {
if (updatedPanels[idx].id == "myUpdatePanel") {
StartSmth();
break;
}
}
}
And it works when UpdatePanel is not inside another UpdatePanel. But when it is inside another UpdatePanel updatedPanels[idx].id has parent Updatepanel id. So how can I get the id of UpdatePanel which initiated the request (the inner UpdatePanel)?

I'm having few UpdatePanels on my master page. And then, I have RadTreeViewcontrol on the page, that should cause partial postback each time node is clicked. Everything works fine there. Since I'm using the same tree on some other pages, I moved this functionality to UserControl. Stuff I've done before, so no problem. Moved some code to ascx, created some events. Everything always worked for me well. But not now. RadTreeView is nested inside UserControl, and this control on master page with update panels, see below:
<asp:Panel ID="pnlContentWrapper" runat="server" CssClass="ContentWrapper">
<div id="HeaderBreadCrumb">
<asp:ContentPlaceHolder ID="HeaderBreadCrumbContent" runat="server" />
</div>
<div id="HeaderMenu">
<asp:UpdatePanel ID="upnlTreeMenu" runat="server">
<ContentTemplate>
<asp:ContentPlaceHolder ID="HeaderMenuContent" runat="server" />
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="treeProductTree" />
</Triggers>
</asp:UpdatePanel>
</div>
<div id="TreeDiv">
<fp:ProductTree ID="treeProductTree" runat="server" />
</div>
<asp:Panel ID="ContentDiv" ClientIDMode="Static" runat="server">
<asp:UpdatePanel ID="upnlTreeContent" runat="server">
<ContentTemplate>
<asp:ContentPlaceHolder ID="TreePageContent" runat="server" />
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="treeProductTree" />
</Triggers>
</asp:UpdatePanel>
</asp:Panel>
</asp:Panel>
And the user control is really simple:
<%@ Control Language="vb" AutoEventWireup="false" CodeBehind="ProductTree.ascx.vb"
Inherits="ProductTree" %>
<div>
<telerik:RadTreeView ID="treeProductTree" ClientIDMode="Static" runat="server" EnableDragAndDrop="false"
SkinID="CustomSkin" CssClass="MasterProductTree" DataFieldID="NodeId" DataFieldParentID="NodeParentId"
DataTextField="NodeName" DataValueField="NodeId" />
</div>
And some code behind:
Imports Telerik.Web.UI
Public Class ProductTree
Inherits System.Web.UI.UserControl
Public Event NodeExpand As EventHandler(Of ProductTreeNodeExpandEventArgs)
Public Event SelectedNodeChange As EventHandler
Protected Sub ProductTree_NodeExpand(ByVal sender As Object, ByVal e As RadTreeNodeEventArgs) _
Handles treeProductTree.NodeExpand
Dim nodeId As Integer = CInt(e.Node.Value)
Dim evetArgs = New ProductTreeNodeExpandEventArgs(nodeId)
RaiseEvent NodeExpand(Me, evetArgs)
//'some logic
End Sub
Protected Sub ProductTree_OnNodeClick(ByVal sender As Object, ByVal e As RadTreeNodeEventArgs) _
Handles treeProductTree.NodeClick
RaiseEvent SelectedNodeChange(Me, New System.EventArgs())
End Sub
End Class
What I don't know is: why is this causing full postback instead of partial? I suspect that it may have something to do with raising my for SelectedNodeChange, but I don't know how to deal with it other way. I need to let other components know, that node selection changed. How can I improve this to make it work with UpdatePanels?
I have run into what seems to be a very famous problem: My updatepanel fires a full postback instead of a async postback. The normal solution is to give all controls you add dynamically an ID, which I have done, but I still get a full postback instead of my async postback. Here's the code:
HTML:
<asp:UpdatePanel ID="ItemsUpdatePanel" runat="server" UpdateMode="Conditional" ChildrenAsTriggers="False">
<Triggers>
</Triggers>
<ContentTemplate>
<asp:ListView ID="PlayerItems" runat="server" GroupItemCount="5"
onitemdatabound="PlayerItems_ItemDataBound">
<LayoutTemplate>
... Listview stuff ...
</asp:ListView>
</ContentTemplate>
</asp:UpdatePanel>
The interesting part is the C# code behind (method PlayerItems_ItemDataBound), which is like the following:
ImageButton imgBtn = new ImageButton();
imgBtn.ID = "itemBtn";
imgBtn.Width = Unit.Pixel(30);
imgBtn.ImageUrl = "~/Images/Game/Items/" + myItem.ItemImageUrl;
ContextMenu menu = new ContextMenu();
menu.BoundControls.Add(imgBtn);
menu.ItemCommand += new CommandEventHandler(menu_ItemCommand);
menu.AutoHide = true;
menu.RolloverColor = Color.Gray;
menu.ID = "MenuMenu";
Panel panel = (Panel)(e.Item.FindControl("ItemPanel"));
panel.Controls.Add(imgBtn);
panel.Controls.Add(menu);
AsyncPostBackTrigger trig = new AsyncPostBackTrigger();
trig.ControlID = menu.UniqueID;
trig.EventName = "ItemCommand";
ItemsUpdatePanel.Triggers.Add(trig);
So, I actually add an AsyncPostBackTrigger to the menu, so the ItemCommand event should be registered. What happends when I click an item in this contextmenu, is a full postback happends. I have been trying to play with the ChildrenAsTriggers property without help.
