AJAX :: UpdatePanel Not Working When Html Editor Is Inside
Feb 2, 2011
Really the title explains it. When i have an HTML Editor (from the AJAX Control Toolkit) inside an UpdatePanel, i get the error message: "Microsoft JScript runtime error: Invalid set operation on read-only property"
I was looking online and it appears it's because the editor uses javascript - is there any workaround for this?
The following is not working (does a full postback). Note: HTML tags inside updatepanel. We can' t have HTML tags inside updatepanel? If so, what's the work around?
When I apply your code for three textbox then it show only one editor and remain same as simple textbox and if i click on button it flickering ...  <asp:ScriptManager ID="ScriptManager1" runat="server"> </asp:ScriptManager> <asp:UpdatePanel ID="UpdatePanel1" runat="server"> <ContentTemplate> <asp:TextBox ID="TextBox1" runat="server" TextMode="MultiLine"></asp:TextBox> <asp:HiddenField ID="HiddenField1" runat="server" />
When inserting a simple embed of youtube inside the ajax editor, on firefox and chrome problems occur. On the other hand on internet explorer 8 everything works fine. I found this solution [URL]
My question is where do I find the DesignPanel.pre.js ?
This is my mistake: If I put an AJAX Editor INSIDE a FormView it loses the layout (I see all the icons button disordered and the Editor without background). If I simultaneously put an Editor inside a FormView and externally in the page both works fine and I see both in the right way. I repeat: with another Editor in the page the Editor inside the FormView works fine!!
I think it may depend on the css, so I have tried to modify the "DesignPanelCssPath" and the "DocumentCssPath" of the Editor inside the FormView, but nothing has changed.
I have populated my data using DataRepeater Control and i have a Delete button on that so each and every row has a delete button which allows user to delete a single entry from DB. I have put this control inside UpdatePanel so i can avoid full page postback.
When i delete the row from the database and try to show a alert message using Repsonse.Write it throws me the below error message
Error: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled. Details: Error parsing near 'itle||Untitled Page|<script language='ja'. Source File: [URL]
But, If i remove my update panel its coming up well, is there any solution so i can show alert box after a row been deleted ?
I have an Editor control on my page and the user can go in use it hit save and that all works.
In another part of the page I have a simple dropdown to select a note and view it. When you push view it loads the text which was entered in via the editor control.
If the user used an order or unordered list. The text shows up but not the list part.
So if they did this:
Example ThisAnd this
What is displaying is
Example This And This
Without the bullets. Same for the numbers.
I have it going to a literal control which should render the html, but it doesn't.
Question for Print functionality in ASP.Net GridView control artical. I tried you code in my project, when click print current page, nothing happens.
So I download your code into my test web project "WebSite1", greate, it works.
Then in your CS.aspx page,
I added (which is the case of my project of using AJAX).
<asp:ScriptManager ID="ScriptManager1" runat="server">Â Â Â Â Â Â Â </asp:ScriptManager> <asp:UpdatePanel ID="UpdatePanel1" runat="server">Â Â Â Â Â Â Â <ContentTemplate> <div>Â Â Â Â Â Â Â <asp:GridView ID="GridView1" runat="server" .......................... gridview stuff gose here ......................... </div> etc etc to close all the tags.
Now run, click print button nothing happens, no any error.
Can you see why put updatePanle for AJAX causing problem ?
I also have to pur EnableEventValidation="false" at top of the page to avoid
Now what I'm expecting it would do is that when you click the button (which is displayed inside fancybox) it would update the textbox and do whatever I define it to do in the codebehind. Unfortunately nothing happens when I click the button.
I've tried to trigger a __doPostback myself passing the ClientID of the updatepanel and/or the button itself. I can't seem to trigger the event in the codebehind however.
The thing is if I remove the fancybox, the updatepanel works as expected. So I am guessing if I can somehow find out what eventhandler logic is behind the button before I create the fancybox, I might be able to recreate the eventhandler logic after attaching fancybox? I just can't find it anywhere...
I am using ASP.Net WebForms 3.5 and JQuery 1.4.1
Update
I got it to trigger the codebehind button_click event by overriding the clientside click event on the button using the code below. The key is in using the name of the button as the sender object for the __doPostBack event. The only problem that remains is that all other values aren't posted back anymore. If I type anything in the textbox, click the button, my codebehind doesn't know what's in the textbox anymore.
$("#popupTrigger").fancybox({ //.... other options, onComplete: function () { $("#RefreshContentButton").click(function () { __doPostBack($(this).attr('name'), ''); }); } });
i am using LinqDataSource and a gridview control and my paging/sorting works fine but when i add <asp:UpdatePanel than its not working, below is my .aspx page and i am not sure what i am missing...
I'm trying to add and edit an image which is located in a detailsview which is inside an UpdatePanel. After I read relevant topics in the forum I installed the Ajax Control Toolkit. Below is my source code. When I used it only for insert new image it worked great. The problem caused when I tried to implement it on the Edit mode, i.e. when I tried to edit the image and upload a different image. Unfortunately it didn't work as I hoped. Nothing happend and the image hasn't been changed. I also tried to change the IDs (AsyncFileUpload ID) to be the same in both places but it didn't work either.
I'm trying to update my web site with the HTMLEditor control for Blog posting. I really need to know what my web.config changes need to be too. I get this error:Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
I have a AJAX editor and I want to put the HTML content in a database and I want to get the HTML data from the database to put in the HTML editor, in HTML mode.
