How To Create User Control As Part Of An .net Web Application
Apr 28, 2010
I have created a user control as part of an asp.net web application. This control works fine. I have then moved the control into a class library and attempted to reference it in my original application. I find that the asp controls created in the ascx for the control (texboxes and buttons) are no longer instantiated i.e. I get a null reference exception in my Page_Load event handler when I try to reference them. The only change to the page in my original application has been to change the register statement to load the control libary dll otherwise this is identical to when the conmtrol was part of the application:

I used the Create User Control to make a new user.
Is there a similar tool (I did not see one) that allows the user to edit their own profile?
If not what is the best way to do it? I have created user tables in AWAT.

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 an application which is installed on local pc and is using SQL db. It is a client management system where I want to add capability to register new clients and give them access to my web site which is sharing the same SQL database with local application.
At the moment clients can register on the web site and I have ASP.NET authorisation system set up with aspnetdb_user, aspnetdb_membership and etc tables. But sometimes it happens that I need to register clients on my local application on PC and ideally would like that registration to create online account for the client as well. Then I want to be able to send him user id and password by email and let him know that he has been registered in my database and online account is ready for him as well.
Basically I want to have full synchronization between asp.net membership service and local application through SQL db. As I said both online and local apps are shareing the same SQL database. what would be the best practice to implement it.

I want to allow each user to create a webpage on our domain. example: www.site.com/username
I've created a few pages that get content from database and place it in a folder. I want each user to be able to edit their own data and when they hit "submit". the system will then copy those pages to a folder and modify the code so it read from the right database.
I keep getting "virtual directory not being configured as an application in IIS" errors. Is there any way around this error? I want the process to be 100% automatic so that I don't need to manually go into the server and configure the IIS myself.

I know how to use ITemplate to create a user control where it looks something like this:
<cust:control id="" runat="server">
<template>
random content...
</template>
</cust:control>
however, i am wanting to make a menu like control, and need a more specific setup. i dont need a template section, however, i want to create something where the user control can have only certain elements (which are also user controls). the best way to describe this is by example i think. this is what i want to create for my user control template:
<cust:control id="" runat="server">
<cust:contolItem id="" runat="" blah="" blah="" />
<cust:contolItem id="" runat="" blah="" blah="" />
<cust:contolItem id="" runat="" blah="" blah="" />
</cust:control>
the outer control is a user control, and inside its tags it can have other user controls (limited to what is defined in the outer controls code). all of the 'children' in the outer control would then be rendered on the outer controls page markup as if it were templated.

I am attempting to create a report using the ReportViewer control in my asp.net web application. I want to use an XML data source for the report. Unfortunately, the XML we want to use as a source is nested to about 6 layers deep in certain spots and we are having a very difficult time trying to determine how to access the data in report. recommend a good tutorial about using hierarchical XML data in a ReportViewer control? All the examples we have seen use XML that is essentially only one level deep.
We have gotten as far as creating different DataSet Tables out of the different elements, and those tables are created with "_id" fields that refer the element to its immediate parent but, we can't figure out how to tie the information together in the report so you could have a report that shows a parent object, then underneath it, a list of its child objects, then the next parent, etc.

I am writing an MVC application, and I wanted to do some extra formatting so the phone numbers all are stored the same. To accomplish this I made a simple external function to strip all non-numeric characters and return the formatted string:
public static string FormatPhone(string phone)
{
string[] temp = { "", "", "" };

I'm starting out learning some ASP.Net programming and I'm going to be making a little community website for my friends and myself.
I was thinking of having a usercontrol and have that 'loginBox' shows the appropriate textboxes and login button, but also show his username when he is logged in.
Do you think I should handle this as a user control or am I missing something as an ASP.Net newbie?

I know you can can do this using MVC. But not sure if you can using Web Forms.
I have a button, when clicked it will get the data then populate a repater then injects the data to other controls. This works fine using postback, but it's a little slow and I want to do it using Ajax.
Is there a way to use JQuery to instantiate the repeater control or the user controls without using postback or using evil update panels?

I want create a user control (Div) like panel to be used in all my web pages. For example, The UserControl can have two DIVs or TRs with a background design. If it's added to a Page, the UserControl has to allow controls to be added into it, i.e. Divs, Labels, and TextBoxes. The height of the div should be AUTO.
