Basically, an old group created a php page with a drop down and this drop down is populated with entries from a DB. The DB owner is currently absent and for the sake of time, I would just need something that turns the entries in that drop down, always at the same url with the same ID every load into a List. Is there a quick, painless way to do this in .NET?

New Address has been inserted ID: 520 Address ID:530 Updated TextBox Name is Blank. or any other mathod. I want to show massage on Single Constant Place.

I am working on a website for a Non-profit, and I am currently using Jquery and CSS to create a dynamic dropdown navigation bar. The code + examples can be found here: [URL]
The Nav menu works great, however when the elements expand, the new content forces the rest of the content on the page to move down and it messes up the entire formatting of the site. Most websites usually just have the Nav bar elements expand OVER the rest of the page without modifying locations...
here is the example code of what I am using:

I have an aspx page which has 18 (yes 18) dropdown lists and 18 text boxes. Each dropdown needs to be selected and each textbox needs to be filled. Dragging and dropping required field validators on these 36 controls and maintaining them is a painful task and does not seem to be the logical option as all I need is for the user to select a value from the dropdown.
Is there anyway I can loop through all these dropdown controls and textbox controls, check if they are empty and display warnings to users accordingly? Client-side validation solution or server side validation solution is fine with me.
I'm building a site where users can purchase 'credits' and buy items on the website with them. I'm wondering, what is the best way of storing the user's overall Credits value? Is it best to do a SUM() of all Credits they have purchased before from the 'Credits.Orders' table, or for performance purposes when they add credits to their account, should it increase a 'Credits' field value in a 'Users' table? For consistency purposes I would like to go with the first option, but the second option sounds better in terms of not running loads of pointless calculations every time I need to know their credit value.

View 9 RepliesI have several dropdownlists which are databound to a SQL DB but I am also needing to add 2 items to them. I am using the code below.
With the code in the Calendar1_SelectionChanged sub (Which is when I want it to fire) It loads the data from the sql but not the static content
If I move the code to the Page_Load sub and add "If Page.IsPostBack Then" then it loads the static content but not the SQL.

I have a private static field in my Controller class in an MVC web application.
I have a static method in that controller that assigns some value to that static field, I want to apply lock on that static field until some other instance method in the controller uses the value stored in the static field and then releases it.
DETAILS:
I have a controller named BaseController having a static ClientId field as follows and two methods as follows:-
public static string ClientId = "";
static void OnClientConnected(string clientId, ref Dictionary<string, object> list)
{
list.Add("a", "b");
// I want the ClientId to be locked here, so that it can not be accessed by other requests coming to the server and wait for ClientId to be released:-
BaseController.clientId = clientId;
}
public ActionResult Handler()
{
if (something)
{
// use the static ClientId here
}
// Release the ClientId here, so it can now be used by other web requests coming to the server.
return View();
}
I did some research after posting. All I found was simple examples for no-layer architectures, like connecting to a database from your aspx page, so, in a corporate environment, it is unnaceptable.
I need to call a server-side method (using ASP.NET Ajax) in a 3-layer architecture.
For example, my Default.aspx contains a method LoadProducts().
[Code]....

This cannot change. There is no way to convert Business and Data layers to static.
How can I call the LoadProducts() method using ASP.NET Ajax?
I have a question about C Sharp ASP.NET:Is there a difference (in code speed, resources) between:public static variable declared in public static class MyGlobals in a 'Code File' template;and the variable declared in a normal 'Class File' template;I use this variable in 2 different Class Files and also in _Default Page codebehind cs file.In fact in my case I need about 20 global variables of type List<string>.

View 1 RepliesI want to run the SQL server Job from the web page.
I have created the SP. Now i want to run this SP By run the Job.
The Job should not be scheduled automatically. I should run this job from front end web screen.
If user clicks the button i want to run the job and return the response back to the screen.
The SP (calculation process) will run for nearly 10 minutes, thats why we are going for this method instead of calling SP directly.
whats the exact use of static variables in overall programming in .net and for asp.net...
Recently i went for the interview where interviewer asked me 2 question which i was not sure for the same..
whats the use of session object, i said sessions are the server side object, they are used when you want to store user specific data at server side, then he asked what if i want to use static variables for the same, i was mum, can anyone tell me how asp.net will behave if i store the user specific information in static variables.If i use cookies which are the best option to store the data at client side (not sensitive one), but what if user has disabled cookies on his machine, will my application would crash.

I have the following structure 3 Dropdown Boxes, the 2nd and 3rd dependant on the 1st and when I change the first combo the pages refreshes with error I am assuming it's happening when posting back. I have nothing in my code behind file for this page so far.

This is a very Basic application that I am creating using Visual Basic and ASP.Net 3.5. Am using a SQL Datasource have searched for this error some of the answers seem extremely complex and I can't figure them out, surely a simple tasks like this has to be easy to bind back to the database from several drop down lists.
Here is my code, using LinQ to get the data from database.
public IEnumerable categoryData()
{
db = new DBModelDataContext();
var cat = from c in db.Categories
select new { c.categoryname,c.categoryid };
return cat;
}
trying to get the values (categoryname and categoryid) into textfiled and valuefield of dropdown list.
dt = new clsData();
ddlCategory.DataSource = dt.categoryData();
what is the code that i need to write to assign the categoryname to textfield and categoryid to valuefield. I mean how to loop through the values coming from the above function.
ddlCategory.DataBind();
i want to add leading space in dropdown list after binding from DB.
for that i used leftpad method but not working.

I am trying to populate a dropdown from a stored procedure that includes parameters. The parameters are programmatically defined variables. I have been working at this for hours, and scoured the internet for a tutorial. I have come up with the following solution below. However, it does not work. Its not pulling any data, and I am not even sure that the page is making it into the GetLast5Schedules_Selecting Event. There has to be a more efficient/less time consuming way to do this!

I have a dropdown list where the user can select a name, on change event populates a Session variable and at the same time populates a formview with the full record detail. I want to add a List Item that states "Select Name" but when I add this the page errors. Input string was not in a correct format.
Description:
An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details:
System.FormatException: Input string was not in a correct format.
Because the value returned from the dropdown list box is a string and not a numeric equal to the first name in the list.
AppendDataBoundItems is = true
AutoPostBack is = true
because I want to update the page as a differnent name is selected. I guess I need to not load the form until an actual first name is selected. Uncertain how to prevent the Formview from loading at page load an until a name is selected and not when the dropdown is set back to "Select Name"
I build a webpage to edit the data entry, all the textbox wroks fine. However when I update the value originally took in using dropdown list , I get error and couldn't get correct update.
