AJAX :: Hidden Or Shown AsyncFileUpload Control Does Not Fire Server-Side
May 27, 2010
I recently came across the AsyncFileUpload control in the latest (3.0.40412) release of the ASP.Net Ajax Control Toolkit. There appears to be an issue when using it in a hidden control that is later revealed, such as a tag with

I have a breakpoint on the UploadedComplete event but it never fires. However, if you take the AsyncFileUpload control out of the , making it visible at initial page render, the control works as expected.

I've got two textboxes running server side and have their visibility turned off. I'm using a couple of ASP.NET controls which require the textboxes to exist. However, I am filling them from the code behind and would not like the user to see this. Can the user turn the visibility on and see the values entered in the text box? I tried using FireBug, and I couldn't seem to select the visibility option in order to edit it. However, I'm quite new to Firebug, so there may be another way? Or does running it server side mean that the client can't ever view the contents of the textbox?
I have a panel extended by the ModalPopupExtender that is sometimes shown using the .Show() method in my code-behind. I have a javascript function that resizes the popup and am able to get it to run when I use the client-side show function but how do I run the same javascript function when using the server-side Show() function?
I just want to find whether the ModalpopupExtender is shown or hidden in Javascript
like,
if($find('ctl00_contentArea_MpInfoError').Show()) // Above line is wrong here i need correct code to find out. { //do something } else { //do something }
I have been using the asyncfileupload control and have everything working nicely with it when uploading. However, also on my page the user can download a file.
If the following path is taken the asyncfileupload does not behave correctly:
1: Download a file
2: Attempt to upload a file via the asyncfileupload
When the user attempts the upload, the previous event is fired, which causes the download to fire again and the asyncfileupload freezes.I'm not sure why this is happening but I think it's to do with the response.end of the download and the
I have developed a web application which contains aspdotnet treeview control. In this treeview control has binded with some database value.. that controls has one parent node and more than one child nodes for each parent node.
my problem is here, when the user clicks the parent node, I need to fire a javascript onclick function before the server side event(SelectedNodeChanged) called..
If I provide javascript to the parnet node when it is binding, then I could not fire the server side event(SelectedNodeChanged).
How to provide onclick javascript event for parent node in treeview control even the parent node has SelectedNodeChanged event.
I cannot get the asyncfileupload to fire the uploadcomplete event at all.
I did a test:Protected Sub AsyncFileUpload1_UploadedComplete(ByVal sender As Object, ByVal e As AjaxControlToolkit.AsyncFileUploadEventArgs) Handles AsyncFileUpload1.UploadedComplete
i use a asyncfileupload control to upload files from my web pages. since i have a listview inside an update panel, and the listview needs to have the file upload functionality, i can not use a asp fileupload control.
the uploaded files are saved inside a temp folder in my application directory. i use a asp:button to upload files from the asyncfieupload control to my temp folder.
as long as i work on my local machine, the upload control inside the listview works perfectly fine, and does what is expected of it (i.e upload files :))
but when i move the code to my web server the asyncfileupload onthe page works just once, that is, it uploads just once (no matter whichever row of the listview it is) and for all other subsequent uploads, it uplaods a file of the same name to my temp folder but with 0KB size.
it beats me why asyncfileupload control would behave this way in the two environments.
could anyone suggest a possible reason/or something i m missing to configure on the server?
The AsyncFileUpload control turns green, indicating that the attachment was successfully uploaded, but the designated method for handling the server side UploadedComplete event is never executed.
My problem is Asyncfileupload control is working fine when i debug the application and upload large file...but when i run this from iis it only upload file less then 5 kb. why is that so?? i did try adding Httpruntime maxRequestLength="4096" i tried to find on search but no help... did m i mising any settings..??
I have two controls, each placed in their own <div> and <UpdatePanel> on my form. I am having trouble getting the partial page postback to fire after the file upload has completed. I have not used the __doPostBack approach before so I'm not sure if I am heading in the right direction.
Initially, ModalPopup Content Container is an empty control.After user clicks on the Button, a async postback will be triggered. During the postback, the server generates the content and appends to ModalPopup Content Container.Also sets the properties of ModalPopupExtender. Finally, calls ModalPopupExtender.Show() method and UpdatePanel.Update() method to show the modal popup.
This method works fine if all controls in ModalPopup Content Container contains simple control. If a control is a button that needs to postback to server side, that is a problem.Since the controls in ModalPopup Content Container is dynamically created. If a control in ModalPopup Content Container triggers a postback event, the control must be created before RaisePostBackEvent is called in server side.
My idea is to determine whether the ModalPopupExtender is hidden or shown in client side in order to re-generate the dynamic control in ModalPopup Content Container.So my question is how to determine a ModalPopupExtender is hidden or shown.
I am calling a Java-script function, in that i am passing the value of hidden field, that hidden field i want to use at server-side, but the value of hidden field is null.
Client Side function
function getDetails() { document.forms[0].HdnNode.value=tree_selected_id; //HTML Hidden Field. str="Cmp_12"; str_array=str.split("_"); var str_array1=str_array[0]; var str_array2=str_array[1]; document.getElementById("<%=HiddenNodeId.ClientId %>").value=str_array1; document.getElementById("<%=HiddenTreeId.ClientId %>").value=str_array2; }
Server Side Function
Public Sub InsertNodes(ByVal NodeId As String) Dim objErrorObj As New ErrorObj Dim ParentID As String ParentID = HiddenNodeParent.Value NodeId = HiddenNodeId.Value Dim NodeIDTree As String NodeIDTree = HiddenTreeId.Value End Sub
I have a large application and I'm going to enabling short-cut key for it. I'd find 2 JQuery plug-ins (demo plug-in 1 - Demo plug-in 2) that do this for me. you can find both of them in this post in StackOverFlowMy application is a completed one and I'm goining to add some functionality to it so I don't want towrite code again.So as a short-cut is just catching a key combination, I'm wonder how can I call the server methods which a short-cut key should fire?
Update: here is the scenario. When User press CTRL+Del the GridView1_OnDeleteCommand so I have this protected void grdDocumentRows_DeleteCommand(object source, System.Web.UI.WebControls.DataGridCommandEventArgs e) { try { DeleteRow(grdDocumentRows.DataKeys[e.Item.ItemIndex].ToString()); [code]...
i am facing the following problem while saving the viewstate on the server side using the savepagestatetopersistencemedium, but this is not working for the pages which contains update panel.

Elsewhere in the page, some JavaScript opens a popup. When the popup is filled out and submitted, I want to use JavaScript to fire that OnSelectedIndexChanged event in the opener page. I found some other code that does something similar:
if (window.opener != null ) { var cf = window.opener.document.forms['aspnetForm']; if (!cf) { cf = window.opener.document.aspnetForm; [code]...
