I would like an UpdatPanel to update it's content once a button is clicked - this button is contained within a UserControl placed on the webpage.However, I cannot just simply reference it using the AsyncPostBackTrigger's ControlID property, because the button is not situated directly on the webpage.
View 2 RepliesI've a ASP.Net page (Default.aspx) which will load UserControl (ucontrol.ascx) dynamically into an UpdatePanel. By using UpdatePanel, we believe we're able to prevent the entire page to be posted-back.
My problem is, within the UserControl, we have some form controls, such as inputs and buttons; after the UserControl is loaded, clicking on any button inside the UserControl will cause the UpdatePanel to be blanked. During the investigation, I found that, breakpoints within the Button1_Click() in the code-behind for the UserControl is never reached. Please reference to the code below, this references to [REFERENCE]1.

i have a usercontrol inside an updatepanel. when i click some button this usercontrol will be loaded. and the usercontrol itself has anither button in it. the problem is that the usercontrol code behind is never executed and when the button is clicked the usercontrol disappears.
View 1 RepliesI have an update panel within it i have my activeX control, below it i have a dropdown that you make a selection from, once you make a selection im trying to pass in different paramters, which really are just the source of the control, since everything else will be the same.. but when i make a selection, the control disappears..
If i remove the update panel and make a selection the control is still visable on the page, at the moment, i dont have much setup, im just trying to get the page layout and framework setup adn working, then i can start plugging in my datasource so actual data is being passed in..
I do have a trigger associated with the updatepanel, but with or without it it still causes the control to disappear..
Just to be clear, it disappearing when i view the page in my browser and make a selection, not within VS. Whats weird is that ONLY that control disappears, the rest of the controls on the page stay visible, the dropdown and buttons.
My page contains a Repeater that is loaded with data asynchronously as the data becomes available, using an UpdatePanel to manage the asynchronous requests.The page contains something a little like this:
<asp:UpdatePanel ID="DataUpdatePanel" runat="server">
<ContentTemplate>
<table>
<asp:Repeater ID="RepeaterBlock" runat="server">
<HeaderTemplate><thead><tr><th>Name</th><th>Status</th><th class="empty"></th></tr></thead></HeaderTemplate>
<ItemTemplate><tr>
[code]...
The problem being that the LinkButton does not appear to trigger a postback of any kind- there is no visible response to clicking on it and putting a break point on the event listener in the codebehind, it is never triggered.
hat the linkbuttons ceased working.
We have a fairly complex content management system where we start with a blank page with just an updatepanel, then in the init function add all the controls, this all works fine.The problem I'm having is that when the loginform control logs in, we get data back from the server that looks like:
|#||4|64|pageRedirect||%2findex.aspx%3feventid%3d1079%26AspxAutoDetectCookieSupport%3d1|1|#||4|15647|updatePanel|ctl00_ContentPlaceHolder1_contentup|
<span id="ctl00_ContentPlaceHolder1_DEBUG"></span><div id="ctl00_ContentPlaceHolder1_content">
<div class="contentWrapper">
<div class="form">
<div id="errors">
<div id="ctl00_ContentPlaceHolder1_ctl03" style="display:none;">
</div></div>

I have a page that has a updatepanel around a gridview control that is within my modalpopup. So you land on the page, there is a link that when clicked will open the model popup. Initially the gridview merely displayed saved records you personally choseto save, well when you selected one, the popup would close and the data from that row would be passed to the gridview within the page to display details.. no issue when it was setup that way.. well eventually it was decided to add a delete option within themodal popup gridview so now when viewing the records you can delete it if not needed. works well.. but now with the updatepanel surrounding the gridview when i click on my "select" link it doesnt execute my
View 3 RepliesI have created a simple modalpopupextender the extender has several options for the search functionality and when i press the okay button it supposed to do a search but.. it not...

look at the code below.btnCustomDateOk dosen't trigger postback at all.it's supposed to run a date range validator (javascript) first and if succeed then triggers a server-side event.(I've been testing around and when I replaced the button with a linkbutton, everything ran perfectly fine, wt? am I misusing the button control?)

Click event is not triggering. This is the head of aspx file:
<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="wucIskalnik.ascx.cs" Inherits="indcms.datapages.wucIskalnik" %>
I don't have an idea what the hell happens just imeddiately that so simple stuff don't want to work.I use some javascript jquery too, and I tried to remove all JavaScript, still the same.. Deleted button and events, reapplied them on page, still not triggering Click event.. Wth?
I have a ListView (table inside) and it's first row are some TextBoxes for filtering actions.
In the last column I have a button that calls my Search function and filters the records according to the inputs.
[Code]....
My Search function for now only displays a text inside a Label at the top of the page.
When I load the page, I'm using ListViewPesquisa.DataBind() so it shows it's EmptyDataTemplate, but when I click the button inside the event isn't called at all. If I do put some data (any data) in the ListView and it shows it's LayoutTemplate instead, the event is called properly.
I can get around this issue by moving the filter line out of the table, but I'd like to know why is that the button inside the EmptyDataTemplate doesn't work.
I have a UserControl, which contains another UserControl with Button. I want to add an event to that button in first UserControl (parent). I tried to do:

btn.Click += new EventHandler(this.SearchButton_Click);
}
but btn is null. How can I do that ?

I am working on a financial portal and I am having a problem..I don;t know what to call it so i mentioned it as an 'unknown to me' problem..I have a webpage..whenever I click on any button on my webpage, the request goes through..but nothing show up on the webpage..then If I click on another link and then again come back to previous link,then only I see the results of button_click..
e.g.
I have a currency conversion and investment form..so after filling up the form in following way and if I click on "INVEST" then nothing shows up..
so now if i click on any other link and go back to 'buy currency' link I see the result as 'investment successful'
So I'm trying to dynamically load a usercontrol into a placeholder in another usercontrol inside a updatepanel.
basically I've got this markup:
<asp:UpdatePanel ID="upPopup" runat="server">
<ContentTemplate>
<UC:Popup runat="server" ID="UC_Popup" />
</ContentTemplate>
</asp:UpdatePanel>
And then this markup inside that usercontrol (Popup):
<div id="modal">
<asp:PlaceHolder ID="phPopupPlaceholder" runat="server"></asp:PlaceHolder>
<asp:Label ID="lblModal" runat="server"></asp:Label>
</div>
In the codebehind of the popup usercontrol I have:
public void Show(UserControl control) {
this.phPopupPlaceholder.Controls.Add(control);
this.lblModal.Text = "Loaded";
}
And I call this show method elsewhere with:
Popup.show(new MyUserControl());
Nothing loads into the placeholder though.
But in the show method I can load regular server-controls fine like this:
this.phPopupPlaceholder.Controls.Add(new Label(){ Text = "Label!" });
Can anyone explain to me why regular controls are loaded fine, but my usercontrol isn't loaded?
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?

View 3 RepliesI have a problem with my Linkbutton which is not firing the RowCommand of my gridview.
Just for an Idea what I am doing is a follows:
1. WebForm
WebForm hosts UserControl_A.
2. UserControl_A = UpdatePanel + Panels + Gridview1 + CollapsiblePanelExtender
Updatepanel of UserControl_A consists of multiple Panels.
Each Panel consists of a Gridview1.
Upon each Panel expand UserControl_B is loaded.
3. UserControl_B = Details View & a couple of Linkbuttons in GridView2
Upon clicking the Linkbutton, unexpectedly it makes a refresh for the entire UserControl_A.
But it does not fire the RowCommand of its parent GridView2.
my problem is it that i when loaded usercontrol in Updatepanel dynamically,so can not execute javascript or jquery code in second usercontrol.
"EconomicBongah.ascx" UserControl work correctly, because that this usercontrol loaded in Page_Load Event for the first time.
when i click on the btn_Article,"EconomicArticleMarket.ascx" UserControl Get loaded, but with the first user control code will interfere,and therefor Javascript or jquery code in second usercontrol can not execute, and encounter with error in Jquery-1.4.4.js file.
i loaded usercontrol dynamically in this case:

Using ASP.NET 3.5 / C#. Have a page with a UpdatePanel, and a UserControl inside the UpdatePanel. When calling ScriptManager.RegisterClientScriptBlock(this, typeof(UpdatePanel), Guid.NewGuid().ToString(), script, false); the script appears to fire (have tried it with a JS alert), but the resulting script also disappears immediately afterword. I am trying to create a JS function via the script, and it is not in the Page Source after the Page is rendered. i have tried many variationsRegisterClientScriptBlock with no luck.
