I have read several post on the TreeView is not/partly working with the UpdatePanel, but none of them mention that an update (triggered by a timer) causes creation of multiple javascript functions in the HTML header. In Mozilla Firefox this a memory leak. I have created a test webapplication to demonstrate the issue we encounter.

I am trying to add validation on my form. I am using AJAX controls in my form fields.
When I remove the Update panel and AJAX control, my validation starts working, but when keeping both the things together, my validation is not working. How could I make them work together?
<script type="text/javascript">
function Validate() {
var QuestionTextArea = document.getElementById("ctl00_ctl00_cphBody_midbox_fvInsert_txtQuestion");
varError = "";
if (!IsTextBoxEmpty(QuestionTextArea, "
Question Text Area not be Empty.")) {
alert(varError);
document.getElementById("ctl00_ctl00_cphBody_midbox_fvInsert_txtQuestion").focus();
return false;
} return true;
}
</script>
<asp:UpdatePanel ID="UpdatePanel2" runat="server">
<ContentTemplate>
<asp:TextBox ID="txtQuestion" runat="server" MaxLength="1000" Columns="50" Rows="5" Style="width: 380px;
float: none" Text='<%# Bind("Description") %>' TextMode="MultiLine" />
<AjaxControl:TextBoxWatermarkExtender runat="server" TargetControlID="txtQuestion"
WatermarkCssClass="water" WatermarkText="Type your Question Here.">

In HTML I usually use the techniqe to check for different statments by calling public Strings and like in this case if test == "notTrue" wich it is not, then the following code in the if statment wont render in the HTML.
It have worked out fine but it does not seem to work for the update panel that I declare. I get this error. I wonder why that is happening and if there is a way to to this in HTML like I do here ?
Microsoft JScript runtime error: Sys.InvalidOperationException: Could not find UpdatePanel with ID 'UpdatePanel1'. If it is being updated dynamically then it must be inside another UpdatePanel.

I have some problem with the AutoCompleteExtender when it's include in an UpdatePanel.
Scenario:
I have create a UserControl with TextBox, AutoCompleteExtender and a "Save" LinkButton and I put this Control in the InsertItemTemplate of a ListView.
The AutoComplete uses a Method that I have created in a webservice.
All works fine untill i place my ListView in an UpdatePanel.
The webmethod don't fired. The strange thing is that if i put the same Control also out of my ListView it seems to work, but i can't catch the linkbutton click.
I use a tabcontrol with 2 tabs. In the second tabpanel as seen in the code I use a Fileuploadcontrol to upload Images from a users computer.
The problem is that I need to surround the tabcontrol with an updatepanel as I dont want a fullpage postback when switching between these 2 tabpanels. In this code I have the tabcontrol inside an updatepanel but the problem is that the Fileupload controls does not seem to work inside an updatepanel.
How will I solve this problem as I dont want a fullpage postback when switching between the tabs ?

I have an onclientclick property on a linkbutton that calls a javascript function.

iam getting the error at bold line . my listbox is inside Update Panel and link button too but java script is outside of Update Panel.
I have a GridView in an UpdatePanel and in the code behind I bind to a Datatable and call the GridView's Sort method:
gvUsers.DataSource = dt;
gvUsers.DataBind();
gvUsers.Sort("DateOfBirth", SortDirection.Descending);
However, this doesn't sort the records. I have the Sort event as an asynch trigger for the grid.
I'm just getting into AJAX (little late I know) and am walking through some of the tutorials on the ASP.NET/AJAX site. One thing I've noticed is that I cannot get the UpdatePanel to work (meaning, prevent a full postback of the page) in the ASP.NET Web Site template. I can use the EXACT same markup, code, and web.config in the AJAX 1.0-Enabled ASP.NET 2.0 template and everything works as expected.

I'm using the technique described on this link to make all TextBoxes on the site highlighted when focused. Basically, in the Page_Load event of the MasterPage I set the onFocus and onBlur attributes for every TextBox found on the current page:
[Code]....
Everything worked fine until I decided to add the UpdatePanel on one page which is used for frequent data entry. Now, when the page loads initially everything is ok, but after the first asynchronus postback is made, controls inside the UpdatePanel seem to loose their onBlur and onFocus efects (controls outside the UpdatePanel are still working fine). I'm not in the best "relations" with AJAX and javascript :)
I hade a user control in my web application that I had inserted into an update panel.. after doing that the javascript of that control stoped working!
View 4 RepliesI have a CustomValidator that validates a control within a web control. The web control is used in a template page that inherits from a master page.
The function is:
[Code]....
I also have this in the code behind of my web control:
ScriptManager.RegisterStartupScript(this, this.GetType(), "script3", "ValidatorHookupControlID('<%= txtGroup.ClientID %>', $('<%= valGroup.ClientID %>'));", true);
Now, the situation is
If I put ValidateGroupComplaint in a standalone js file (linked from the master page), then the alert line will always display nothing and always return false.
If I put ValidateGroupComplaint in a script block inside my web control, then it will work IF the web control is not in a UpdatePanel. If it is inside a UpdatePanel then it simply can't find the validator function (JS Error: object expected).
I have an UpdatePanel on the page which I'd like to trigger using javascript.First of all my code perfectly works if it's in a website not being inheriting from a masterpage. Now when you put exactly the same code into a website which inherits from a masterpage, the UpdatePanel wouldn't get fired anymore.

I cannot use asyncFileUpload as it has too many restrictions which doesn't meet our requirement.
I'm able to add a updatepanel trigger to force the Button1 to perform a postback. after the file uploaded, I need to use a timer to do different tasks and return messages back to client with the timer. That is all fine.
However, when one upload is finished. I try to do it again. The FileUpload1.HasFile is "false". I don't know why. if I remove the timer, at the second time, the HasFile is "true". I think there must be something in the timer and disable the Button1's postback.

I have a FileUpload Control on the page with validation and it is working smoothly.
Later there is an important demand to have it partially updated so we enclose it with UpdatePanel.
Then problem comes up when user browse file and press upload button, no file is uploaded.
Is it we cannot do partial rendering with FileUploader ?
I have problem to show method value on asp:Panel.
This is my *.aspx code :

Code Behind :

In this case, I can't show value myMethod at code behind to aspx file where this method is called.
If I use postBackTrigger in upControl updatePanel then the method(myMehod) will show on upShow updatePanel. But the updateProgress doesn't work.
