I have a problem with maintaining state in an ASP.NET AJAX page. Short version: I need some way to update the page ViewState after an async callback has been made, to reflect any state changes the server made during the async call. This seems to be a common problem, but I will describe my scenario to help explain: I have a grid-like c...
The ASP.NET AJAX ModalPopupExtender has OnCancelScript and OnOkScript properties, but it doesn't seem to have an OnShowScript property. I'd like to specify a javascript function to run each time the popup is shown. In past situations, I set the TargetControlID to a dummy control and provide my own control that first does some JS code a...
I have a database that contains a date and we are using the MaskedEditExtender (MEE) and MaskedEditValidator to make sure the dates are appropriate. However, we want the Admins to be able to go in and change the data (specifically the date) if necessary. How can I have the MEE field pre-populate with the database value when the data ...
I'm fairly new to ASP.NET and trying to learn how things are done. I come from a C# background so the code-behind portion is easy, but thinking like a web developer is unfamiliar. I have an aspx page that contains a grid of checkboxes. I have a button that is coded via a Button_Click event to collect a list of which rows are checked and...
Yes, it sounds crazy....It might be. The final updatepanel does not appear to trigger anything, it just refreshes the update panels and does not call back to the usercontrol hosting it. Any ideas? EDIT: I got it posting back, however the controls inside the final usercontrol have lost their data...I'm thinking its because the main rep...
When you get a badge or aren't logged in to stack overflow there's a groovy little notification bar at the top of the page that lets you know there's something going on. I know the SOflow team use JQuery, but I was wondering if anyone knew of an implementation of the same style of notification system in asp.net AJAX. On a side note, wh...
I'm sure this is easy but I can't figure it out: I have an ASP.NET page with some UpdatePanels on it. I want the page to completely load with some 'Please wait' text in the UpdatePanels. Then once the page is completely loaded I want to call a code-behind function to update the UpdatePanel. Any ideas as to what combination of Javascr...
I'm using an older version of ASP.NET AJAX due to runtime limitations, Placing a ASP.NET Validator inside of an update panel does not work. Is there a trick to make these work, or do I need to use the ValidatorCallOut control that comes with the AJAX toolkit? ...
I have a gridview that is within an updatepanel for a modal popup I have on a page. The issue is that the entire page refreshes every time I click an imagebutton that is within my gridview. This causes my entire page to load and since I have grayed out the rest of the page so that the user cannot click on it this is very annoying. Does ...
According to Microsoft the FileUpload control is not compatible with an AJAX UpdatePanel. I am aware that a PostBackTrigger can be added to the submit button of the form like this: <Triggers> <asp:PostBackTrigger ControlID="Button1" /> </Triggers> The problem is that this forces the form to perform a full post-back which voids out...
I'm looking for a way to check within pageLoad() if this method is raised during load event because of a postback/async postback or because of being loaded and access the first time. This is similar to Page.IsPostback property within code behind page. TIA, Ricky ...
I've started working with ASP.net AJAX (finally ☺). and I've got an update panel together with a asp:UpdateProgress. My Problem: The UpdateProgress always forces a line-break, because it renders out as a div-tag. Is there any way to force it being a span instead? I want to display it on the same line as some other controls without havin...
We've been using "Drip" to try and identify why pages with UpdatePanels in them tend to use a lot of client-side memory. With a page with a regular postback, we are seeing 0 leaks detected by Drip. However, when we add an update panel to the mix, every single DOM object that is inside of the update panel appears to leak (according to D...
I've got a web application working using VB and Ajax. I'm using updatepanels to avoid the irritating "flicker" on postbacks to the server. I would like to have a button control defined within the updatepanel itself (tried moving it outside and got some catastrophic error, so left it there) that makes the current panel not visible and ...
Ok, so my method in my webservice requires a type to be passed, it is called in the ServiceMethod property of the AutoCompleteExtender, I am fuzzy about how I should do that so I called it like this: ServiceMethod="DropDownLoad<<%=(typeof)subCategory%>>" where subCategory is a page property that looks like this: protected SubCategory...
I have a basic CRUD form that uses PageMethods to update the user details, however the Validators don't fire off, I think I need to manually initialize the validators and check whether the validation has passed in my javascript save method. Any ideas on how to do this? ...
ValidateEvents is a great ASP.net function, but the Yellow Screen of Death is not so nice. I found a way how to handle the HttpRequestValidationException gracefully here, but that does not work with ASP.net AJAX properly. Basically, I got an UpdatePanel with a TextBox and a Button, and when the user types in HTML into the Textbox, a Ja...
I need to display aditional information, like a tooltip, but it's a lot of info (about 500 - 600 characters) on the items in a RadioButtonList. I now trigger the update on a PanelUpdate when the user selects an item in the RadioButtonList,using OnSelectedIndexChanged and AutoPostBack. What I would like to do, is trigger this on onMouse...
I'm planning to develop an ASP.NET server control to provide asynchronous username availability validation for new user registrations. The control will allow a developer to point it at a "username" TextBox and it will provide an indication of whether or not the username is available. Like this example, but without the clunky UpdatePane...
I'm working on a Silverlight application where I want to take advantage of the Microsoft ASP.NET AJAX Client library. I'm calling the library using the HTML Bridge that is part of Silverlight 2. Silverlight got great support for passing types between JavaScript and Managed Code, but now I've bumped against a problem. Microsoft ASP.NET A...
