I'm fairly new to ASP.NET but I have developed quite a few WinForms apps in C# where I've used the System.Drawing.Bitmap namespace extensively without much issues.
Today, I decided to write some code to dynamically create some PNGs on the fly in my Page_Load event and everything seems to work fine. But I notice this scary looking warning on the microsoft documentaion site. What is up with that ??
I am unaware of any other ways to deal with images in .Net except using System.Drawing.Bitmap ...
Does anyone out there use ComponentOne's C1Menu and create a menu with subitems at runtime?

View 1 RepliesI need to create 2 cascading dropdown menus for a website. I am really new to ASP so don't understand a lot of it yet.. now is that the website pulls the list items from a SQL database and I don't want to use this method. I need to use either JavaScript or just hard code the items. Here are the directions for what I need to do:
Drop down list box for selecting a state (populate it with names of five states)

View 3 RepliesHow to bind menus dynamically with database in asp.net.
View 1 RepliesI'm doing some research on security and sitemaps in ASP.net and am unfortunately running short on time. I have not worked too much with ASP.net security so I'm not completely sure if I'm heading in the right direction.
Here is my problem:
I have a public website (i.e. on the internet) that will allow any user to sign up to. The website will be developed using ASP.net webforms. These users may create other users and assign these users different roles.
Different roles have different restrictions and the menu is displayed appropriately. For example, a user acting as an administrator can see all menu options. Whereas a limited user will only see some of these menu items.
There needs to be the ability for users on our end to modify what pages certain roles can access. For example, if Role1 can do task X, we would like to be able at some point modify Role1 to no longer do task X. This would be done using an application built in-house.
User types (roles) are to be saved in the database. User permissions (what pages each type can have access to) are also to be saved saved in the database.
Here is something I am thinking of doing:
Implement the authorization and authentication set up built in to ASP.net using the web.config fileUse Sitemaps to dynamically create menus/breadcrumbs from the database
I believe it is possible to do the second one using custom providers (please correct me if I'm wrong). But I am not entirely sure if it's possible to configure the web.config file dynamically.
I suppose this is really more of a yes/no answer but I would just like to make sure I'm not going in the wrong direction. I will be using VS2008 and .net 3.5 framework.

View 2 RepliesCurrently, on our production IIS web farm, we host about 15 applications in a single App Pool (Default App Pool). There are two websites and about 13 virtual directories.A colleague has recommended that we change our IIS configuration so each application is a separate App Pool (with identical settings).
Is there any drawback or potential issues to doing this?Is it possible that ASP.NET applications could have been built with the requirements that they are all within the same App Pool?

I need to create a dynamically expanding div tag, and I am not too sure how to go about it. Basically, I have a bulleted list control, which will be inserted inside a div tag. The div tag's height is set to about 70px. When more than 5 list items are added to the bulleted list control, I want the div tag's height to expand to show the rest of the items. What I was thinking is when there are more than 5 list items, to have a little linkbutton with the word more, and to click on this button, which will then expand on the div tag.

I am currently using datasets for my data access layer. I currently store the connection string in the web.config file. I need the ability to change the connection to another database before any queries are processed. Is there an event that is triggered or a base class that can be modified that intercepts the process of retrieving the connection string from the web.config file? Is there any way to handle multiple database connections using the same code base and also take advantage of the connection pooling? I understand the best method is to get rid of datasets and use custom data objects.

I have a requirement whereby one or more image buttons need to be created in a user control at runtime. The number of buttons is determined from a database where a user can add one or more rows that contain an image for each button, so if a user adds 3 images to a table, 3 image buttons are created. Ive used this code but I get an error at runtime
The control collection cannot be modified during DataBind, Init, Load, PreRender or Unload phases.

this is the usercontrol aspx

I basically want one or more buttons to render within the div in the usercontrol. Ive only got the code written for one button at the moment while I test the rendering, eventually they will be rendered in a loop of records taken from a database. Whats the best way to do this ?

View 6 RepliesCan I dynamically create controls in Silverlight without a postback to the server (even an asynchronous one). Does silverlight drag-n-drop requires postback?

Can I avoid such problems in Silverlight?
I have a GridView with a column of checkboxes. I also have a panel pnlSubmitOffer which serves as a modal dialog with ajaxToolkit:ModalPopupExtender:
[Code]....
I need a set of controls (text boxes and datetimepickers) to appear on the modal dialog based on how many checkboxes in the GridView are checked, i.e. a set for each checked record. Thus the controls should be added to the panel dynamically. But I don't know how to do it, as btnSubmitOffer click is not handled, because the modal dialog appears first. I was told that the controls can be added dynamically using javascript, but my knowledge of it is not enough.
