I have quite a number of user controls that I need to embed in Umbraco macros. Each user control has quite a bit of in page javascript that needs loaded into the page.
I have been building up the javascript with StringBuilder.Appendline then registering a startup script with code behind but this stinks and I feel there has to be a better way of going about this.
I am trying to catch an event that is in a user control inside a master page contentholder and refresh the content page. I am having a hard time finding a good example. Even on this site I am timing out on search.
View 3 RepliesI 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?
View 1 RepliesI have implemented a custom ErrorController with NoAccess Action returning the View "~/Error/NoAccess" (not inside the Shared folder).
I have also modified the web.config file and add a custom error "<error statusCode="403" redirect="~/Error/NoAccess" />" node.
Each time i enter to an anauthorized page, i get redirected to the logon page (even though i am already logged on). I would to modify the default asp.net mvc authorization functionality and each time a user tries to enter a page that is not authorized to get an "NoAccess" page instead of redirecting to the login page.
I think I summed up the question in the title. Here is some further elaboration...I have a web user control that is used in multiple places, sometimes more than once on a given page.The web user control has a specific set of JavaScript functions (mostly jQuery code) that are containted within *.js files and automatically inserted into page headers.However, when I want to use the control more than once on a page, the *.js files are included 'n' number of times and, rightly so, the browser gets confused as to which control it's meant to be executing which function on.What do I need to do in order to resolve this problem? I've been staring at this all day and I'm at a loss.

In ASP.Net I have a few custom controls I've made. I utilized jQuery where it helped also. Well, one problem I have now(with obvious, but "bad" workarounds) is that for each user control I need to execute some code from within pageLoad($(document).ready will not work with update panels). Well so now my problem. I need to have two custom controls attach to the pageLoad event. What would be the best way of doing this? I can't just do
old_pageLoad=pageLoad
pageLoad=function(){... old_pageLoad();}
because these custom controls can be used more than once on a page and the script needs to run for every single instance of the control, plus what if I had 3 different custom controls on the page? the only method I've come up with is something like this which seems super hackish:
old_pageLoad_<%= MyStaticClass.GetUniqueID() %>=pageLoad;
pageLoad=function(){... old_pageLoad_<%= MyStaticClass.GetUniqueID() %>();}
Are there any better ways of handling function conflicts like this? I have also seen this MSDN article but what it suggests doing seems worse to me than what I am currently doing.
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?
I'm fairly new working with Javascript. I'm working on an issue where I have a GridView with multiple Checkboxes and Radiobuttons. A user can check multiple checkboxes and if a radiobutton is selected, a checkbox has to be selected. This scenario is working fine, presently with existing asp.net code. But, I want to automate it using Javascript, so that I could avoid a postback.
View 4 RepliesI've got a .aspx page which loads a user control using the LoadControl(string virtualPath) method. The loaded control contains references to several other user controls (i will call "modules"). If such a module contains an unhandled coding error which isn't catched at compile time (e.g. division by zero), no helpful error is thrown. The .aspx page just gets an error from the LoadControl method that the control to load cannot be found (404), but in fact it contains a faulty module.
Is it possible to get the error of the module from within the .aspx page for better troubleshooting? Can I get information about, that (in this example) there is a division by zero error in module (nested user control) xy?
I have a user control called ucTriStateButton. It raises an event when it is clicked, called TriStateButtonClicked. If I put this user control on a page, it works fine. Here is the declaration on the .aspx page:
[Code]....
When the button is clicked the method tsbTest_TriStateButtonClicked executes correctly.
The problem is when I put the user control in template field of a GridView.
[Code]....
There is no way to hook the event handler to the control in Page_Load because I cannot get a reference to tsbMorning. So I did it in the RowDataBound event handler of the GridView, where I also do a bunch of other row-specific stuff. Although this builds and runs, the event is never actually subscribed to and so never gets fired.
So the question is - how can I handle an event from many instances of the same user control within a GridView? I am calling the same bit of code regardless of which user control is actually clicked. I only need to know that one was clicked.
I am programatically adding a control to an aspx page and binding a server side event to an index changed event inside the control. (It's a RadListBox from Telerik's ASP.NET controls) The problem is that on the postback triggered from the control, the event doesn't hit its eventhandler because on the postback the control isn't defined. Is there a way to handle this without having to retrace the logic taken before and rebuild the controls so the events that stem from it are processed?
View 1 RepliesI have a user control embedded in a web part. It has the following snippets of code:

Why are some controls initialised and others not? How do I get around this if I'd like to update the Text property on currentPageLabel?
Update:
I've placed breakpoints all the way through the page life cycle and found that nextButton and currentPageLabel are never initialised. The breakpoints were placed at OnLoad, CreateChildControls, goButton_Click, OnPreRender, Render and OnUnload.
how one might go about implementing your own custom tags in JS pages served by ASP.NET?
Basically what I am looking to achieve is a way of creating "includes" for my Javascript files by adding some code such as.
//Include Src="MyJavascriptFileLocation.JS"
And then having the ASP.Net handler serve my javascript file but also dynamically append the referenced javascript file to the location where the include is written.
I've been reading around the web about different alternatives to keeping track of users but I can't seem to find the "perfect" solution for my situation.
The app will (hopefully) be high-volume so I'd like to design with scalability in mind. It might be necessary to host the site using several web-servers so session mode InProc won't work, right? It's kept in memory of the current web-server and since the user might jump from web-server to web-server I can't be sure the session will be kept connected to the user.
Do I need to make a custom membership and role provider that works with mySQL to be able to use the .NETs standard user handling systems (like FormsAuthentication that can handle session stuff from what I've understood)?
i have some problem with my userControl. Pls look below for better understanding. Pic1. The default page. When i click on the links on the left, userControl will load into the placeHolder as in pic2.

How should one handle the situation where you may need to filter by a group of users.
Here is the scenario.
I have an administrator role in my company. I should be able to see all the data belonging to me plus all the other users who I have control over.
A plain old user however should only be able to access their own data.
If you are writing regular sql statements then you can have a security table with every user and who they have access too but i'm not sure how to handle this situation in the OO and ORM world.
Any one dealt with this scenario in a web application using an ORM?
I have a User Control which consists of a TextBox with a few extras, but for purposes of this example just assuming it's a plain TextBox will be sufficient. I am calling this User Control from a Web Form and would like to be able to use a RequiredFieldValidator that basically would function the same as if I used it on a TextBox on the web form. How do I configure my User Control to handle this?
EDIT:
DatePicker.ascx
<asp:TextBox runat="server" ID="myControlTB">
DatePicker.ascx.cs
[ValidationProperty("Text")]
public partial class DatePicker : System.Web.UI.UserControl

I have a user control which I am dynamically loading in my page_load event via a method (see below). The user control contains a gridview and a label. A key piece of information has to do with how to get around the convenient feature of gridviews not rendering when their datasource is empty. In my user control I add some hidden rows so that the grids will render and the user can see just the headers (if the situation calls for it).
The nomControl is an asp:Panel on the parent page which will hold the user controls. The dsRefinedProductsNomInfo is a strongly typed dataset.
[code]....
how I should be handling my events so that my rendered grid is up to date and not showing these hidden rows. I have a feeling I am just doing things in the wrong place/order but this is my first real swim in the deep end of the asp.net pool.
I am part of a team that is developing a SharePoint web part. My task is to create a user control which will ultimately be wrapped in another class for presentation in a web part. Because of these requirements, I must fit all of my code in a single user control.To organize my code in the code-behind, I created a few private classes for the different objects which are represented in the database. I want to add some exception handling whereby if some sort of DB exception is thrown I can update a message on the page informing the user of the problem.
My problem is that the page-level controls are inaccessible from the private class where I'm issuing the query, so even if I catch the exception I have no way of directly accessing a Label control to populate the error. I tried to create a baseclass with an EventHandler defined, but when I throw events from the private class I'm not able to catch them for whatever reason. I'm far from an OOP expert Here is a snippet:
ASP Code:
using System;
using System.Collections;

I have a user control say SearchVendor.ascx which contains 4 buttons a gridview and another user control. I need to load the control dynamically actually as a modal pop up
I get this code
var uc = Page.LoadControl("~/blah/VendorProductSearch.ascx") as VPSearch;
uc.ShowVPSearch(true);
_tempPlaceHolder.Controls.Add(uc);
it works fine the control gets loaded properly but onclick of any button the second time the control disappears ?
I want the dynamically added control to remain until the user clicks on the cancel button
I have a ModalPopupExtender that needs to be hidden whenever the user clicks anywhere else on the page, window, or scrollbar. I have a function and it works if i set it to a div tag but what about when the user clicks the windows scrollbar?
function HideList() {$find("<%=ModalPopupExtender1.BehaviorID%>").hide();
