View 8 RepliesUpdatePanel Dynamically Loaded Web UserControl Will Disappear After Clicking Any Button Inside The UserControl?
Mar 17, 2011I'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.

View 4 RepliesAJAX :: UserControl With ScriptManager And UpdatePanel, Some Pages With ScriptManager?
Feb 8, 2011I have a user control with both an UpdatePanel and a ScriptManager.
Some pages in the system have a ScriptManager of their own, and need to include the UserControl.
This throws the "You can only have 1 ScriptManager" exception.
If I remove UserControl's ScriptManager, I'll get 'UpdatePanel1 requires a Script Manager" exception.
I've tried to modify the UserControl to dynamically include it's own script manager if none exists. But all the methods I've used before involve adding a delegate to Page.OnInit-- which won't work, since the UserControl Init fires first.
Because the system designers here like making my life difficult, I can't create a MasterPage, or a BasePage for the system in inherit off of. I'd be stuck going to each page an adding a ScriptManager before the UserControl on each of them. Is there any way of, in the UserControl, detecting if the page has a ScriptManager, and if not, adding it dynamically in a way that makes the UpdatePanel happy?
AJAX :: Nested UserControl With UserControl Disappears On Partial Postback
Jan 28, 2011I have a page with an UpdatePanel with a UserControl in it. That UserControl contains a GridView with a nested UserControl that seems to disappear when the parent UserControl is rebound. I cannot for the life of me figure out why the child UserControl disappears. The code works beautifully on the first load, but any partial postback causes the "Pick" UserControl to disappear.

C# - Dynamically Loading Usercontrol In Updatepanel?
Feb 16, 2011So 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?
UserControl Causes Full Postback In UpdatePanel
Mar 24, 2011I'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?

Jun 23, 2010I 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 clicking the Linkbutton, unexpectedly it makes a refresh for the entire UserControl_A.
But it does not fire the RowCommand of its parent GridView2.

View 2 RepliesC# - Wrong State In Server Controls With Same ID's When Dynamically Adding UserControl To UpdatePanel?
Feb 6, 2010Here is what I am trying to do. I have a page with two link buttons and an updatepanel (the two linkbuttons trigger the updatepanel). I have two usercontrols which have labels with same ID's. When I click the first link button, I add the first usercontrol to the updatepanel and set the label value to datetime.now
when i click the second link button i add the second usercontrol but i see that the value of the label from the first control is set in the label in second user control. if the id's are different there is no problem - but in my case the usercontrols are being developed by different teams and I am integrating them in the way i mentioned - so they may have same ids.

AJAX :: How To Trigger Updatepanel Postback From Another Updatepanel
Mar 4, 2011 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?

View 3 RepliesAJAX :: UpdatePanel Conditional Update OnLoad Event / Updatepanel To Update On Queue?
Aug 25, 2010i have a website with three UpdatePanel Control and inside of each UpdatePanels has ONE Gridview and a SqlDataSource Control.
all gridviews are connected to its own SqlDataSource Control. so technically when i run my website all gridviews automatically get their data from their respective SqlDataSource Control and display them accordingly.
but what i need to do is instead of letting all the update panels to load each gridview their data upon Onload event, i need the updatepanel to update on queue, (Technically changing the UpdateMode to Conditional does not solve my problem.) there will be an event which will trigger the updatepanel to update later.
