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.
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 RepliesAltough questions somehow similar to this have been asked for a number of times, but the question is still unsolved. Here is the question: I have a gridview which is contained in a tab container ajax control which itself is inside an updatepanel. Gridview works excellent and its corresponding methods are fired accurately, but when I enable paging, (e.g.) after I click on page 2, the gridview hides itself. here is my PageIndexChanging method:
protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
GridView1.PageIndex = e.NewPageIndex;
GridView1.DataBind();
UpdatePanel2.Update();
}
Why paging causes gridview to stop working correctly? What can I do?
I created a .NET user control to work as a DropdownCheckbox and added Jquery to give the sliding and hide effects. The code is as below:

This control works fine in a normal page, but once I put it inside an update panel it doesn't work. Is there a work around or simply I can't use JQuery inside 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 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 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 asyncfileupload control within a panel control. The panel is initially set to visible=false on page load. After a user clicks a button to display the panel contents however, I set the panel to visible and the user can then use the asyncfileupload. The problem however, is it seems much of the javascript associated with the asyncfileupload, does not function properly when the panel containing the upload control is set from invisible to visible. If I set my panel's "visible" property to "true" initially, then it works fine. My javascript error message is as follows:
"Form contains a file input, but is missing method=POST and enctype=multipart/form-data on the form. The file will not be sent."
Basically within my asyncfileupload control, I have the following line:
[Code]....
In this scenario, my "args" variable is always null (when I set my pane's "visible" property to "true" on page load, the args variable DOES contain data. Any idea why switching a panel from visible=false to visible=true, would cause an error like this?
I have a input of type file and when i try to do a Request.files when the input is wrapped in an update panel...it always returns an empty httpfilecollection. Why???
This is the codebehind: (At HttpContext.Current.Request.Files...its always 0 for the count.)

although I've searched already, but here is the thing:I have a ModalPopup wich have a Textbox, a Button and a GridView inside. The Gridview is binded to a SQLDatasource object, and the Select query is something like "SELECT field_1, field_2, field_3, field_4 FROM Table_Name WHERE field_1 LIKE '%@Parameter_2%'".This ModalPopup is used (or gonna be used) to search for a field, so the parameters received by the Query is the text inside the Textbox, I've linked thid inside the SQLDataSource Wizard.The problem is that everything works perfectly fine... inside the panel WITHOUT the ModalPopup Extender, but whe I add the Extender the filter function doesn't work.Here is my code:
[Code]....
Notes: I have a ScriptManager inside the MasterPage, so I don't have to insert one in every page. Also I've tested the code in a new page (the one I use for testing), and it works fine, it filters and everything, the problem is when I add a ModalPopup to the panel.

I have many controls like dropdown, radiobuttonlist, etc on my page and I put all these controls inside the update panel so that the page doesn't look to be posting back when something is selected. Now the working on the page is very smooth. But the session object isn't getting refreshed even if I postback to the server and as a result even if the users are working on the page they are being sent to the login screen after 20 mins.
Is there anyway where I could put all the controls in update panel and still refresh the session after any postback(dropdown selection)
i have set of link buttons outside update panel but when click any one of them they donot work at all , when i set the postbackUrl they make full postback my source code :

I have a ListView1 control that his <ItemTempleae> has a another ListView2. ListView2 is surrounded by <UpdatePanel> with trigger and also UpdateMode="Conditional". But, I don't know why ListView2 is not being update as it should, I need to refresh all the page to see the new data enter to ListView2 only. What is the problem? How can it be fixed? I think that the problem is something in the structure. There are about 10 ListView2 with updatepanel surronded them, so when I am looking to update a specific ListView2, it doesn't know which one to update because there are lots of them. What to do in order to solve that problem?
View 3 Replies<asp:UpdatePanel ID="UpdatePanel1" runat="server">

<asp:FileUpload onchange="clickTheButton();" ID="FileUpload1" runat="server" />

Button 1 is outside the update panel and the javascript that gets run when a user adds a file in the upload box is this:
function clickTheButton() {
document.getElementById('<%= Button1.ClientID %>').click();
}
The problem is simple. FileUpload1.HasFile == false. I don't know why this is, but when I put it in the update panel it ceases to work.
I have seen some other threads on this. But none of them answer why this is happening, they just point to things you can download.
EDIT: Really my main reason for wanting to do this is so that I can get a ..Uploading File.. Tag to pop up while the client is uploading to the server and once it has completed, display it in a datalist. I just cant get the UpdateProgress to work.
When there is an error with CompareValidators, the triggers for the UpdatePanel stop working. I didn't find any info about that..
View 1 RepliesI've just discovered that the X-Requested-With header in IE is always "XMLHttpRequest, XMLHttpRequest" instead of just "XMLHttpRequest". I found the reason in MicrosoftMvcAjax.debug.js at line 280 (MVC 2.0). Seems there is no need to add this header again as it is already done in Microsoft AJAX Library. And because of this IsAjaxRequest extension method doesn't work anymore if there is no X-Requested-With param in the request body. And this make X-Requested-With header useless in IE.
In Firefox there is no problem as it doesn't append but replace the existing header value. Not tested in other browsers.
