I want to create dynamic integer variable for each role in this loop. Which I will user later for totaling item count in other logic.
Is this possible to create a runtime dynamic variable?
Below I have a bunch of SQL statements that creates a table at runtime and the "pic" column is a dynamic column and the code creates the number of "pic" columns depending on the count of the uploader control. the problem comes when I try to insert into that table and I am trying to say for every "pic" declare variable @pic....
it works well for just one file in the uploader but for multiple files i get the following error
The name "pic1" is not permitted in this context. Valid expressions are constants, constant expressions, and (in some contexts) variables. Column names are not permitted.
Directory.CreateDirectory(MapPath(".") & "port" & clientname.Text & "")
Dim objConn As New SqlConnection("Data Source=xxxxxxxxx.hostedresource.com; Initial Catalog=mrpoteat; User ID=xxxxxxx; Password=xxxxxxxxx;")
objConn.Open()
Dim strCommandText As String = ""

I have some global variables declared and want to access them in subrorutines using the For statement.
For example, I want to use the following to place values in the global variables , i.e, dblcell1, dblcell2, dblcell3, etc.

I finally got the DynamicLibrary issue nailed down I asked about in another post. The basic gist is that there's a project table that renders to a View. The user can, at runtime, choose the columns to display and the order in which they should be displayed. Here's the method that does the work:
[Code]....
This works great. The SerializeToCsv() method is an extension method I created for generic string lists. I used the jQuery UI bundle to create a sortable set of 'ul li' elements with checkboxes in them, which allows users to select which columns to show, and in what order. When the post happens, the current order the elements are in on the View is the order in which they're added to the FormCollection, so I don't need to do anything special to track ordering. So far, all is working according to my evil plans.
The problem I have now is how to render this in the View dynamically at runtime. It's very easy to check for the Model's property values and display them selectively, but not to reorder them. Off the top of my head, I can think of a few ways to do this, but none of them are very attractive. The first idea is to send the Model in as a collection of objects. The query that returns the data as shown above already has the columns returned in the order the user chose, so I could wrap them in objects and render them as string representations in the View. This is clunky, ugly, and won't give me the support for the actual data types boxed in the objects. I'd have to convert them all to strings in the service class and then wrap them in objects, because the View wouldn't know if it was dealing with a DateTime, string, int or whatever. I REALLY don't want to take this route. Can anyone give me some advice on a better way to reorder and selectively display columns at runtime?

I am generating dynamic textboxes with the ids as follows table row 1:
no1,name1,addressline11,addressline21,city,pin,communicationAddress1(here the row count I am appending at last to the control id's)table row 2: no2,name2,addressline12,addressline22,city,pin,communicationaddress2
table row 3: no3,name3,addressline13,addressline23,city,pin,communicationaddress3 and so on....
A new will be created when user hits enter key in the last textbox i.e., communicationaddress.For validations I have used java script. Now my requirement is when user types the address line the content of the textbox should be copied to communication address.
communication address = addressline1+addressline2+city+pin
so in theabove four textboxes when the user hits the keys the matter appending to the communication address with ',' seperated. I acheived this through key press event in java script..................
In my Page_Load() event, I'm calling a Sub (in a module UserMenu.vb) that reads an XML file which has the user menu entries. The final menu should be an <ul> with several <li>, some of them with anidated <ul> within. As I understand, I may use a asp:Panel in my page to position a container for this elements I read and in this sub I try to add them using new BulletedList and new ListElement BList.Items.Add(LItem)), but when I get to Panel.Controls.Add(BList) it throws an error that says BList should be inserted in a Form. Why? Aren't they just <ul> and <li>? What other alternative I have to create <ul> and <li> in a specific part of my page?
View 3 RepliesI am making a web project now. And i meet some problems working with Entity Framework. My program needs to have dynamic model. I try to explain. So i have classes and database is created from them. At the beginning of work program checks in folder Modules for assemblies and looks for classses that needs to be created as tables in database(this classes have to become a part of ef model). And i need at runtime create database.If some new classes was added so add this tables to database, but not recreate it(as it is made by default). If i delete classes the tables are not deleted.

I have a project where I need to create menu buttons from a list in SQL Server. The problem I am having is that I need to add code to the text of those buttons. So there would be a birthday button and it should display the number of birthdays within the next two weeks or a button with the number of upcoming events.
Clarification:
There is no code yet, just some requirements. What I am doing is querying a table to get the list of buttons to display. Now each of these buttons may have dynamic text, for things like count of birthdays, events,etc... I am trying to see what the best way would be to handle this. Should I embed a snippet of code to go along with the menu item to execute when I iterate over the menu items? Maybe I should build a javascript file to go along with the code, which I add code to query a service for certain menu items?

How Create Page In runtime
View 5 RepliesI was wondering is it possible to create a css class at runtime?
I am unable to use the traditional method of doing so as one of the attributes need to be loaded at runtime.
As I am using the Coolite Toolkit, whenever i need to use a custom image onto one of the controls, the custom image path needs to be loaded in via a stylesheet class.
I've figured out how to create the controls in the format I want, but now I am confused as to how create more than one set of them. I set everything to new and increment the names of each control, but it's only updating the one set. Here is my code:
