AJAX :: Hiding TargetControlID After Postback Processes?
Jan 15, 2010
I'm firing the my ModalPopupExtender from a server side button click (bthAuth) and then need to hide that button after my processing is complete. When btnAuth.Visible = False is called it displays the ModalPopupExtender. If I remove this piece of code the window goes away like it should.
I have a asp.net page that contains a Ajax TabContainer control with three tabs, this is all dynamically created and added using the code-behind file. Inside each tab I have one or more gridview controls that can cause a postback for various reasons.
When a gridview control causes a postback, the entire tabcontainer gets hidden on the page and therefore nothing is displayed. In the HTML source code I can see that the controls have been added to the page, but the tabcontainer has a style added to it (style="visibility: hidden"]. If I remove this style using the developer tools, the tabcontainer displays and all tabs, but some of the styling gets lost. Is there a specific reason why this occurs and how I can resolve this?
I am using this jQuery context popup menu extension:http://www.trendskitchens.co.nz/jquery/contextmenu/ This context menu is bound against an ASP.NET treeview adding a context menu to all items.All contained within an update panel.In order to select the item when right clicking, I am using JQuery to parse the postback from HREF that would normally fire when the tree item is being clicked, and using eval() against this HREF.This results in a post-back to IIS. Immediately after is my JQuery code for displaying the context menu.The context menu appears briefly however goes as soon as IIS returns the updated page data.Just after some general advice on how people think is best to approach this. I can avoid this by making users LEFT click the tree node prior to right clicking it, but that just seems unintuitive.
When I browse to my page that has the modal popup panel on it, the panel initially is visable, and when I do a postback it acts as intended. let me know if you need the master page....
How can I show loading image for the user while executing long running process in an ASP.Net Ajax application? Is there a way other than using Page Methods? Any ideas?
I wantto show up manually a ModalPopupextender without its TargetControlID assigned to anything. Thus I dont need a button or linkbutton that triggers to show it up.
I put a hiddenfield and attached it to TargetControlID and I can call ModalPopup manually by its show() method.
so why should I have to assign TargetControlID ? I dont wantto use a useless hiddenfield to attach as its Target.is there any other Ajax Control Modal Window that no need a Target ?
I have a gridview showing list of data . When I select one of the row in the gridview, I would like to get panal (say Panel1) to be popup. I used the Ajax ModalPopupExtender but I don't know what should be the value in TargetControlID ?
i want to use a ComponentArt:ToolBarItem ID as TargetControlID in AjaxControlToolkit ModalPopupExtender. my ComponentArt:ToolBarItem ID is "save" but when i write this (TargetControlID="save") this error apears:
The TargetControlID of 'ModalPopupExtender' is not valid. A control with ID 'save' could not be found.
I'm trying to use a ModalPopupExtender in a user control, so the TargetControl is on the previous (parent) page. In the PageLoad event of the user control, the following code finds the MPE and the button from the previous page, but I don't understand how to actually assign the button to the MPE as the TargetControlID.
+ $exception {"The TargetControlID of 'DynamicPopulateFileDownloadUI' is not valid. A control with ID 'PanelDownLoadUI' could not be found."} System.Exception {System.InvalidOperationException}
Apparently, I cannot display or hide a Panel through ModalPopupExtender if the TargetControlID is not visible in the webform.
The TargetControl of my ModalPopupExtender is button_displayPanel. But once the panel's shown and closed, I hide button_displayPanel and another button is displayed. I need to be able to open the panel from this 2nd button.
Basically, I need to show the panel through another button since the ModalPopupExtender's TargetControl will not be visible.
I use javascript to show the panel::
[Code]....
If the target control's invisible, I get error "Error: 'null' is null or not an object" since the control's not rendered.
im using AnimationExtender 2 fadeout a panel n d click event of a image..im using sme 10 images n same page and shld i write separate AnimationExtender for all images...
how 2 change d targetcontrolid of d animation extender n a javascript function....
On each image, I want to open a popup with "Download" & "Print" buttons.
I was thinking to create a panel and open a popup on linkbutton click by using ajaxToolkit:ModalPopupExtender . But, I realized that for I will need 3 such panels & ModalPopup's for each image as got to set TargetControlId for each link button.
In my other page, I will have more than 10 images.
What can be the best way to achieve this goal in such way that thru out my app I can call this popup and download or print the image ?
I have template column in grid view where data is binding to a link button. Now I want to show my model popup on click of that link button but it is giving error :
"The TargetControlID of 'ViewAdd' is not valid. A control with ID 'lnkedit' could not be found."
It is working for me but the major problem is that in modelpopup extender in which i have given targetcontrolid of PanelCountry so when i click on next page of Gridview in it opens a PopUp,while i want to open popup when Edit button of Gridview is clicked not for next page of Gridview.
I mean how i will set the TargetcontrolId of Edit button of Gridview in PanelCountry for modelpopup.
I am using ASP.NET 2.0 with VB. In design view of grid, i have one textbox in its template field. I also have one Ajax Calender Extender and FilteredTextBox Extender. I have set target controlId of both calender and filteredtextbox extender equal to that textbox. Now dynamically i dispose one of the extender from that textbox. everything works ok. But once my page reloads it takes the original design image, means both extenders are being set to that textbox.
I'm running IIS 7 on Server 2008, with a single AppPool for an application which is basically just a collection of ASP.NET WebMethods. Some of these methods process for hours before they return. What's weird,is that sometimes when I launch multiple simultaneous requests IIS spins up a single w3wp process (and seems to share it amongst the requests) and other times it spins up multiple w3wp processes.
I want to get all the processes that is meant for a particular session. i.e if there are two persons who are using my web application then i want to get all the processes used by user1 and all the processes used by user2.
I can get all processes by writing Process.GetProcesses() but how to get it in a group.
in my ASP.NET app happen asynchronously (i.e in background threads without any access to HttpContext). Let me take an example of one such action. The app would be deployed to a web farm soon.
The background threads would be processing files deposited to a network share location. So, when the app starts, I create a FilesystemWatcher to monitor activities on the desired network share folder.
As soon as a new file arrives, the code processes it and marks it as completed processing.
The problem is with multiple servers watching the same network share, the same file might get processed on different machines, meaning redundant results. On a single server, I use locking mechanisms to prevent race conditions.
I'd like to display an animated gif after user presses a submit button which causes postback. I'm following Joe Stagner's tutorial
here. The page worked fine. But now that I've added the update panel around the button and then an update progress with a gif in it, the app doesn't run.
Now, when the button is pressed, the animated gif appears and runs for about three seconds or so (due to the artificial latency added as per the tutorial - System.Threading.Thread.Sleep(3000) ) and then it stops, nothing returns from the server.
What am I doing wrong and what am I not understanding with this Ajax process and the server?
(by the way I'm using the toolscript manager that came with the Ajax control toolkit, don't know if that matters)
