Multiple Instances of User Control

  

I have a user control that I place on a page severl times.  When I make a selection on a ddl in one one control the SelectedIndexChanged event fires for all the control on the page for that ddl.  So I get duplication of an insert that I do.  Is there a way to make sure these events are isolated so this doesn't happen.

Thanks,

User control with multiple item content

  
I have a user control that I would like to contain multiple items as its content, similar to the way a <StackPanel> works. I tried using a <ContentPresent/> but it will only let me use a single item as the control's content. What's the best way to go about this? I realize I could just require the user to put a <StackPanel> or <Grid> or similar control as the content of the user control, but i would rather not do that if possible.   I'm not sure if it matters, but this control actually has several content presenters. Some of them will contain a single item and some will contain multiple items.

Multiple Instances Same User Control

  
I have an ASP.NET page inside of an ASP.NET Master page, and inside the page I have two instances of the same web user control. I have given them different IDs, but when I click a button on the first user control it causes the second user control to do the expected activity and the first one does nothing. Is there something I need to do to make sure that the controls don't get confused? P.S. The expected activity is that when the button is clicked one panel object is disabled and another is shown. When the button is clicked on custom control 1 the panel on custom control 2 is disabled and it's next panel is shown and custom control 1 does nothing. Thanks for the help.

Need a good solution on how to allow a user to upload multiple files

  

Hi
Im currently working on a project where i have a form that users fill out in order to submit issues.
My ask is to give the user the ability to upload multiple files together with the form submission and also go back each time they have an update and upload more if they need.
The way i have it right now is that i only have one FileUpload Control and once the Save button is clicked the file is save in the database together with the form info.

 I already has a separate table for the files with reference to the ticket but im just not sure how can i allow the user to submit as many files as they want in an easy way.

Any ideas?

DataAnnotation on multiple user controls displaying on wrong control

  


I have a table that displays a user control on each row. The user controls are strongly typed to a viewmodel which contains DataAnnotation style validation. If one of the rows has invalid data entered (lets say the 3rd row) the data annotation validates display agains the first row/user control.

How do I get the data annotation to show against the relevant user control?

I'd post a pic to show what I mean except it will not display it!.:/

SPSWC:ProfilePropertyValue and multiple values user properties

  

Hi, I'm trying to customize the profile.aspx page in My Profile (SP 2010). All works fine except for the fact that I can't see the values of the user properties configured as multiple-value fields.

I'm using spswc:ProfilePropertyValue and what I get is a list of value separator (comma or semicolon, as configured in the user property) without values.

Do you know how to display multiple value user properties?

Thank you

Using same user store for multiple apps

  

I have spent hours on the forum trying to find this answer.  I have a requirement on a project.  There is an internal (intranet employees only) site which has much more control over the data etc.  and i have an external site (to allow customers to enter usage data).  I am using forms auth and hitting a common sql server 2008 db with the standard aspnet schema.  I have an internal web server and an external web server both windows 2003.  The problem that i am having is that if you are logged into the external site and then open a new ie window and enter into the internal site, even as a different user it logs you out of the external and vice versa.  I don't have access to update the machine config. 

I started out as a single app in the db but now have seperated into 2 apps and i am able to log in as an external admin and see only the external users and vice versa.  Creating a seperate security only db for the external app is not an option because i have a  

I have the application name listed in the web.config for both internal and external which matches the app name in the aspnet_applications table.

            <providers>
