AJAX :: Forcing Full Postback In UpdatePanel

Apr 19, 2010

I have basically the following structure set up :

[Code]....

I am aware that a FileUpload requires a full page postback. I read the article http://www.4guysfromrolla.com/articles/090209-1.aspx[^]I tried to install a PostBackTrigger programmatically to get a full postback only on the ImageButton1 control. All other postbacks must be partial. (GridView sorting, paging, ...)In code behind I do :

[Code]....

The above code does not seem to install a full postback only for the ImageButton1, so the file upload fails. How can I make this work ?

I have a webform which has an updatepanel with a combobox, add button, delete button and a table. The functiion of the two buttons is to add or delete table rows. However, the table is getting cleared everytime the combobox item is selected. Is there anotherway of retaining the table contents?The code for the updatepanel is:

AJAX :: Updatepanel Asyncpostback Triggering A Full Postback

Apr 1, 2011

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|

This gives a quite strange result: Every 5s my whole page gives a full postback. When I comment in (activate) the asyncpostbacktrigger, the updatepanel does not give a full postback. In the PlayerItems_ItemDataBound I have the following code (which, I do think, do not matter):

When I create a NEW updatepanel, ItemsUpdatePanel1, it does not fire a full postback without the timer. I can even start copying items from ItemsUpdatePanel to ItemsUpdatePanel1, and suddenly the full postbacks happen. I tried 2 seperate times, and they started happening at different times. I simply want the UpdatePanel NOT to give a full postback, even without a timer.

AJAX :: Custom Control In Updatepanel Should Create Full Postback?

Jun 2, 2010

I am searching already the web for some hours to get this working. I created a custom control (ConfigTree), which has a treeview as part of it. I put the custom control into an update panel. So far so good. When I click on different buttons (in ucc:ConfigTree) or the treeview in the custom control an async postback is done. When clicking on a node in the treeview an event for the parent element (ConfigTree) is generated, which populates again an event (NodeSelected) for the parent element (shown below). Different parent elements can handle the event differently. In one element (this one) I need to transform the async postback in a real postback with full page refresh. For better understanding see the following code:

[Code]....

the parent element (here shown) should process the OnNodeSelected and transform it into an full postback and not just an async postback, but only this event, all the other events in the ucc:ConfigTree should processed async. How can I do that? Is there a method to call in the code behind?

AJAX :: Child Elements In LinkButton Break UpdatePanel Functionality, Cause Full Postback

Apr 21, 2010

If I set up a repeater that has LinkButton controls, an UpdatePanel works great. If I add child elements to the LinkButton,such as SPAN, the UpdatePanel stops working as expected. If you click on the area of the LinkButton everything still works, but if you click on the area of the SPAN inside of the LinkButton, you get a full PostBack.I've tried setting ChildrenAsTriggers to true and a few hundred other things. Nothing seems to work. I think the UpdatePanel sees that the "click" event happened on the SPAN and doesn't know to capture it for an async postback.

AJAX :: Forcing A Postback From An Asp.net Extender

Mar 12, 2010

I have been trying to figure out out to force a postback from an asp ajax extender. The closest post that I can find is

http://forums.asp.net/t/984558.aspx

However I am pretty sure this was at least one migration ago. Additionally I am using VB as my programming language so some of the conversion may be the problem.

I think I am pretty clear on what needs to be done.

If I am correct the steps are...

Create a new property in the extender to hold the postback command for each target control that is using the extender.

Then in the Onload populate that property (Use GetPostBackEventReference to get the ASP valid target ID ) so it can be called from the Clientbehavior.js

My problem is the syntax in the for-each loop that allows me to iterate through the target controls.

UserControl Causes Full Postback In UpdatePanel

Mar 24, 2011

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?

Updatepanel Gives Full Postback Instead Of Asyncpostback

Nov 30, 2010

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.

AJAX :: Forcing Postback On Textbox - Update Not Working

Mar 8, 2010

Hoping I have placed my question in the correct forum.

I am writing an application that simply updates a text box (contained in a AJAX UpdatePanel) via a thread. the eventual idea being that the textbox will be placed in the master page, and a thread will poll a table to check for status messages. 90% of the code works as it should, the only side that is not working, is physically updating the textbox. The value of the textbox is being updated, but it is not being reflected on the screen. When the text is updated in the textbox, the OnChange event is not firing (as it shouldn't), but I still need the textbox to be updated. The textbox is being updated prgramatically, and not by the user.

When the thread triggers, it just fires an event, which right now just updates the textbox with the current date time. I've tried a million and one different ways, but still no luck :( Anyone know where I am going wrong?

Here is my code:

<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" UpdateMode="Always" runat="server">
<ContentTemplate>
<asp:Table ID="Table1" runat="server">
<asp:TableRow>
<asp:TableCell>
<asp:Label ID="lblThread1" runat="server" Text="Thread1"></asp:Label>
</asp:TableCell>
<asp:TableCell>
<asp:TextBox ID="txtThread1" AutoPostBack="true" runat="server"></asp:TextBox>
</asp:TableCell>
<asp:TableCell>
<asp:Button ID="btnstartThread1" runat="server" Text="Start Thread 1" onclick="btnstartThread1_Click" />
</asp:TableCell>
<asp:TableCell>
<asp:Button ID="btnStopThread1" runat="server" Text="Stop Thread 1" onclick="btnStopThread1_Click" />
</asp:TableCell>
</asp:TableRow>
</asp:Table>
</ContentTemplate>
</asp:UpdatePanel>

public partial class _Default : System.Web.UI.Page
{
private static clsThread1 _objObject1 = new clsThread1();
private static Thread _objThread1;

//****************************************
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
_objObject1.UpdateThread1Time += new EventHandler(UpdateThread1TimeEvent);

//****************************************

C# - Timer Results In Updatepanel Gives Full Postback

// Add all events bound to item into contextmenu
itemPanel.Controls.Add(firstLiteral);
foreach (Delegate del in myItem.Actions.Items)
{
Literal firstItLit = new Literal();
firstItLit.Text += "<li>";
itemPanel.Controls.Add(firstItLit);
MethodInfo methodInfo = del.Method;

UpdatePanel With GridView With LinkButton With Image Causes Full Postback

Apr 20, 2010

So this might be a fairly specific issue but I figured I'd post it since I spent hours struggling with it before I was able to determine the cause.

<asp:GridView ID="gvAttachments" DataKeyNames="UploadedID" AutoGenerateColumns="false" OnSelectedIndexChanged="gvAttachments_SelectedIndexChanged" runat="server">
<EmptyDataTemplate>There are no attachments associated to this email template.</EmptyDataTemplate>
<Columns>
<asp:TemplateField ItemStyle-Width="100%">
<ItemTemplate>
<asp:LinkButton CommandName="Select" runat="server"><img src="/images/icons/trashcan.png" style="border: none;" /></asp:LinkButton>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>

In the ItemTemplate of the TemplateField of the GridView I have a LinkButton with an image inside of it. Normally I do this when I have an image with some text next to it but this time, for whatever reason, I just have the image. This causes the UpdatePanel to always do a full postback.

Force A Full PostBack From An ItemTemplate Inside A GridView In An UpdatePanel?

Dec 16, 2010

I found this solution to force full postbacks from within an UpdatePanel

<Triggers>
<asp:PostBackTrigger ControlID="controlID" />
</Triggers>

but my control is actually inside an ItemTemplate nested in a GridView. Therefore when my page loads, it doesn't find that control.

How can I force a full postback from my control (an asp:LinkButton) from within my GridView?

C# - Forcing A Postback Asp.Net

May 12, 2010

Please take a look at the following click event...

Protected Sub btnDownloadEmpl_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnDownloadEmpl.Click
Dim emplTable As DataTable = SiteAccess.DownloadEmployee_H()
Dim d As String = Format(Date.Now, "d")
Dim ad() As String = d.Split("/")
Dim fd As String = ad(0) & ad(1)
Dim fn As String = "E_" & fd & ".csv"
Response.ContentType = "text/csv"
Response.AddHeader("Content-Disposition", "attachment; filename=" & fn)
CreateCSVFile(emplTable, Response.Output)
Response.Flush()
Response.End()
lblEmpl.Visible = True
End Sub

This code simply exports data from a datatable to a csv file. The problem here is lblEmpl.Visible=true never gets hit because this code doesnt cause a postback to the server. Even if I put the line of code lblEmpl.Visible=true at the top of the click event the line executes fine, but the page is never updated. How can I fix this?

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?

AJAX :: Update Panel Doing Full Postback?

Oct 20, 2010

I am having an issue with an update panel, which is still causing the entire page to postback.

I have made sure i have all the correct bits in the web.config, section groups, httphandlers, httpmodules, additonal assemly etc... but it still does not work. I have got it to work in a way,which is why i think i have the config right, because if i take the search panel of and place it outwith the update panel, the go button only postsback the rest of the page not what is inside the updatepanel.

I am using a master page, but the update panel only appears in the content page, within the content tags.
