C# - Making An Ajax Call In Umbraco From Inside User Control?
Mar 11, 2011
For an Umbraco project, I am trying to make a simple Ajax call.. I can't use PageMethods because I need to make the call from inside a UserControl.. I tried to do it via web service call like this:
Web service method:
[System.Web.Script.Services.ScriptService]
public class MapService : System.Web.Services.WebService
{
[WebMethod]
[Code]...
The problem is, "MapService.GetCities" method doesn't get invoked..
What might be the problem here?
Alternatively, what is there any better way to make these kind of Ajax calls in a User Control?
Is it required to use a RESTful service to be able to make a ajax call to a wcf service (for example: by using WebInvoke attribute on Operation contracts). Once a service is made RESTful by adding a webHttp binding on the service host, can the host have other endpoints as well? (wsHttp or netTcp). Is it required that the aspNetCompatibilityEnabled be set to true for a service that has webHttp binding (and can this setting coexist for other endpoints). I understand I can use both JQuery and ScriptManager for making WCF calls on the client. Why should I use one over the other?
I was wondering if there's a way in Umbraco to log errors that we get when it fails to load xslt or user-controls. Generally it shows a red box saying it couldn't load the control and stuff. Is there a way to properly log this?
If you visit this [URL] and then click on the link like the image below you'll see in-line pop-up DIV which displays a busy status of Ajax callback before it displays the information. So, the information is not there yet until you click on the link.
I have a Page that expects a POST Request and returns some JSON. Essentially it's an .ashx Page, but that doesn't really matter.
When using jQuery, I would use jQuery.Post with "json" as dataType to simply make the POST request and get an object back. However, for the current project I mainly use ASP.net AJAX and I don't want to add jQuery just for the call.
For ASP.net AJAX, I only found information on how to call a "traditional" web service though, which means adding a asp:ServiceReference to the ScriptManager and having a "real" Web Service at the end.
Is there a simpler way to make a POST call to a Page? I could live with getting the raw JSON and then manually eval()ing it, but I don't want to create a full asmx web service (deploying them on SharePoint is a bit painful, and my ashx handler works fine)
I tried to take advantage of jQuery AJAX call to enhance user experience but I am facing a tricky problem.
When the user does nothing for a period of time, e.g. 30 minutes to reach authentication timeout, making AJAX call becomes the problem. The server side will return login page and display in my target div section. The simplest solution I can think of is to inject a dummy tag in login page, and when detecting such dummy tag then use javascript to redirect to login page. But this means that I have to do that every time I make AJAX call.
How can I get all the textboxes inside a create user wizard control using getElementsByTagName().
Below is my JQuery code:
[Code]....
The above code isn't displaying hint text when the textbox retreives focus.
I think there is something wrong with this getElementsByTagName("asp:TextBox"); , I have also tried getElementsByTagName("TextBox"); , getElementsByTagName(":textbox"); and getElementsByTagName("input"); .
But no one of them gets the textboxes array.
Can anyone tell what will be the correct syntax for getting all the textboxes inside a create user wizard control using getElementsByTagName()?
I have one user control which has 2 gridview first grid has columns (GroupName, Description, chkRemove checkbox) another gridview has columns (GroupName, Description, chkAdd), apart from that i dont have any code on .cs file of usercontrol.
I want to call same user control on 4 aspx pages and datagrid binding, sorting, paging and search functionality i want to do on respective aspx.cs pages not on user control where i am calling this uercontrol because for every aspx page field name is same but when i am binding the data to the grid that logic is different.
For first aspx page i called my usercontrol like this and everything is working fine: -
I've created a sign up form in a normal .aspx page, with some TextBoxWatermarkExtendes, PasswordStrength, RegularExpressionValidator, and more..it worked perfectly..I have inserted it all inside the modal content div in this SimpleModal:http://www.ericmmartin.com/projects/simplemodal-demos/(the OSX style dalog) the First problem:I have a toolkit script manager, and an update panel surrounding the "username" textbox, with enabled autopostback, so it checks if user is taken or not when the textbox looses focus and shows a message in label..when it runs for the first time (when it's working) first of all, the passwordStrength control doesn't work, secondly, after I type something in the username textbox and make it lose focus (press tab or click outside), it's watermark text of course gets deleted when i focus on it, and another watermark text from another textbox gets deleted (i dont know why) SO after like 1 or 2 seconds, the text I wrote gets deleted and replaced by the watermark, for BOTH textboxes that had watermarks
Second problem:the first time, the it works normal, but when I close the modal and open it again, the textBoxWatermark changes to a normal text inside the textbox, even the "Sign up" button stops working, and expression validators and required validators and stuff stop working..
I have a custom control created to autofill the box as typed in. Its working great. But if I put the control inside an Update Panel, it works for the full postback but if partial postback happens (because of the update panel), it does not work.
TabSecciones.Tabs.Clear(); //the panel container TabPanel nuevoTab = new TabPanel(); encabezadoSeccion encabezadoSec = new encabezadoSeccion(); //A user control, a couple of labels and a table nuevoTab.Controls.Add(encabezadoSec); TabSecciones.Tabs.Add(nuevoTab);
For some strange reason, the user control is "outside" of the panels, thus visible no matter what panel is selected... if I programatically insert another control (ie: a texbox) inside another panel, it works fine...
I have a requirement where in i have to create a common pop up extender for all the user controls.How can i achieve this by using ajax modal pop up extender?Please help out with the following questions i have.Is it possible to bring user control inside a ajax modal pop up extender.?If yes, Is it a best practice?How can we build a common Ajax Modal Pop Up extender so that it can be re used for all the user controls?Consequences we face while using user control inside ajax modal pop up ?Is there any better approach for having user control inside modal pop up.?
I have this datalist in a user control i want when i keep mouse over "More", it should be invisible. it is working on .aspx page not on user control. How to do this. This control is placed on master page.
Autocompleteextender not working inside an user control tried all ways. i have a custom function.. inside the cs file itself like the following :-
[Code]....
I did something like this and it worked properly when it was in aspx but when i changed all this to ascx and when i added the user control in aspx the autocomplete is not working. say enablecontext = false; i have even tried that.. its not even reaching till that function. moreover i need contextkey to validate different autocomplete controls inside my page.
I have an ajax tabcontainer on a master page that has a user control inside one of its tabs.The user control is just a gridview that gets a list populated from a DB table.The strange thing is that the gridview is displaying in VS, but when I build the site the tab is empty; no error message just nothing.Below is the code for the tab in my master page:
I have an application in which inside my aspx page i have an user control which gets loaded at runtime.Inside this user control I have collapsible panel extender from ajax toolkit for which i have inserted scriptmanager tag at the starting of user control.At run time I am getting an error only one instance of script manager can be added...though I have not added script manager in my aspx apge..
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:
[Code]....
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 am hosting a Windows User Control in my web page using <object> tag. Everything works fine when the control is outside the updatepanel and is independent of other web controls but when I move the control inside the update panel, it doen't load the user control properly.
why it doesn't render the control properly and what can I do to fix it?
I tried moving the user control outside the update panel but since this user control is shown/hidden dynamically and is rendered based on other web controls which are inside an Update Panel, the user control is not shown at all.
I am developing web application and in application i need to make call of jQuery using .ajax(); method with datatype is set jsonp. Now all works well with limited data but problem start to occur when data size is increasing......
