C# - How To Keep TinyMCE After Postback In An UpdatePanel
Aug 17, 2010
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 have a ASP.NET 4.0 based CMS, where i use the TinyMCE (3.4) via jQuery to edit one Textbox.In addition to this i have several other textboxes. There is also another DropDown List on the Page, which controls the Contenttype.This Control has AutoPostback enabled and sets the visibility on the textboxes regarding the selectes item.As i want to keep the Postback Validation on i have configured the TinyXML to use xml for the content serialisation (encoding: "xml").Now i have the problem, when a postback from e.g. the DropDown List occures, the re-encodes the content.
Init: "Hallo"
1st Postback: "<p>Hallo</p>"
2nd Postback: "<p><p>Hallo</p></p>"
i have enabled the original textarea via css and this seems to be a problem of the TinyMCS's Save method.
Does anybody have a solution, how to fix this issue maybe with a custom save_callback on the TinyMCE?

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?

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 created a form in a popup div, that contain an UpdatePanel with ImageButtons in it.Initially, I used LinkButtons to test but I wanted ImageButtons. The thing is, it works well with LinkButtons and not with ImageButtons (absolutely nothing happens).
<a href="javascript:WebForm_DoPostBackWithOptions(new
WebForm_PostBackOptions("ctl00$cphC$ctrlAdr$AdrMapo$lbAdresseSaisie",
"", true, "",
"", false, true))"
id="ctl00_cphC_ctrlAdr_AdrMapo_lbAdresseSaisie">test</a>

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);

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.

avoiding postback using updatepanel

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.

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 :

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 quite strange situation where I have the following code:
<asp:Timer ID="GameClock" runat="server" Interval="5000" Enabled="true"
ontick="GameClock_Tick">
</asp:Timer>
<asp:UpdatePanel ID="ItemsUpdatePanel" runat="server" UpdateMode="Conditional" ChildrenAsTriggers="false">
<Triggers>
NOTE THE TRIGGER IS COMMENTED OUT
<%--<asp:AsyncPostBackTrigger ControlID="GameClock" EventName="Tick" />--%>
</Triggers>
<ContentTemplate>
<asp:ListView ID="PlayerItems" runat="server" GroupItemCount="7"
onitemdatabound="PlayerItems_ItemDataBound">
<LayoutTemplate>
<table border="1" cellpadding="2" cellspacing="0" runat="server" id="tblProducts">
<tr runat="server" id="groupPlaceholder">
</tr>
</table>
</LayoutTemplate>
<ItemTemplate>
<td id="Td1" runat="server" style="vertical-align:top; text-align:left; height:100%;">
<div>
<div id="category" runat="server">
<asp:Panel ID="ItemPanel" runat="server">
</asp:Panel>
</div>
</div>
</td>
</ItemTemplate>
<GroupTemplate>
<tr runat="server" id="productRow">
<td runat="server" id="itemPlaceholder"></td>
</tr>
</GroupTemplate>
</asp:ListView>
</ContentTemplate>
</asp:UpdatePanel>
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):
protected void PlayerItems_ItemDataBound(object sender, ListViewItemEventArgs e)
{
if (e.Item.ItemType == ListViewItemType.DataItem)
{
ListViewDataItem dataItem = e.Item as ListViewDataItem;
if (dataItem != null)
{
BaseItem myItem = dataItem.DataItem as BaseItem;
Panel itemPanel = new Panel();
Literal firstLiteral = new Literal();
firstLiteral.Text += "<div id='smoothmenu1' class='ddsmoothmenu'>";
firstLiteral.Text += "<ul>";
firstLiteral.Text += "<li><img src='Images/Game/Items/" + myItem.ItemImageUrl + "' />";
firstLiteral.Text += "<ul>";
// 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;
string commandName = myItem.ItemId + "|" + methodInfo.Name;
LinkButton btn = new LinkButton();
btn.Text = methodInfo.Name;
btn.Click += new EventHandler(btn_Click);
btn.CommandName = commandName;
itemPanel.Controls.Add(btn);
Literal secondItLit = new Literal();
secondItLit.Text += "</li>";
itemPanel.Controls.Add(secondItLit);
}
Literal btnLiteral = new Literal();
btnLiteral.Text += "</ul>";
btnLiteral.Text += "</li>";
btnLiteral.Text += "</ul>";
btnLiteral.Text += "</div>";
itemPanel.Controls.Add(btnLiteral);
Panel panel = (Panel)(e.Item.FindControl("ItemPanel"));
panel.Controls.Add(itemPanel);
}
}
}
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.
