C# - Populate Drop Down List With Month / Year?
Jan 22, 2011
I have a date and I need to populate a drop-down with the months/years between that date and today. For instance, if that date is 10/14/2010 then the drop-down should contain October 2010, November 2010, December 2010, January 2010.
The way I'm thinking of doing this is to pass that date to a function, loop from today backwards step 1 month while adding each month to a collection until we reach that date and finally return a collection of strings. Then, populate the drop-down control on page load. Finally, use some ajax with a page method to parse back the string and trigger a partial page reload.

I am having an application which should contains a datepicker with drop down list for year and month. So how can I insert Drop down list into an ajax calendar extender control. I can't use 3rd party .dll like Calendar extender plus or 3rd party tools like jquery.

I'm trying to populate a drop down list from a datatable. Is this correct way of doing it?
public ViewResult Index()
{
ViewData["CampaignList"] = List;
return View();
}
public IEnumerable<SelectListItem> List
{
get
{
DataTable dt = CampaignRow.GetList(DB, 100, true);
List<SelectListItem> list = new List<SelectListItem>();
foreach (DataRow row in dt.Rows)
{
list.Add(new SelectListItem
{
Text = Convert.ToString(row["CampaignName"]),
Value = Convert.ToString(row["CampaignId"]),
});
}
return list;
}
}
how can i stylize drop down list? how can i add an empty first value ie "select campaign"

Is it possible to populate the values of a drop down list inside a repeater when the user chooses to activate the drop down list? I have a page that has 2300 rows of data generated by a repeater. The users have the option of showing a drop down list or not. If the drop down list is shown, right now I bind the values in the drop down list at the time the repeater is generated so they are available immediately.However, this adds an additional 2mb of data to the page, which increases the amount if time that it takes to render the page. I am being asked to decrease the page size. The idea they have is that if I only load the first value of the drop down list into the repeater, the amount of data on the page would drop significantly (which it does).
The problem becomes, how do I then load the remaining items into the drop down list when the user SELECTS the drop down list? These aren't static values, they are completely dependent on the data row key, so I have to go out to the DB and get the values for that individual row.I thought maybe AJAX and jquery, but can that be done inside the repeater?Ayone have any ideas as to if/how this could be done? Personally, I think the users should be educated that it is going to take an additional 5 seconds for the page to load if they choose to display the dropdowns, but the business is hesitant to go that route.

This may or may not be possible but I'm trying my best to find out, I'm a complete novice when it comes to ASP.At the moment I have drafted a basic html page. This page contains a drop down list and several tables all hidden by javascript and then displayed based on the drop down selection (onchange event)I'm trying to convert this into an asp page so that I can dynamically populate the drop down from a table (this will be a list of names)and then based on the drop down selection (onchange does not necessarily have to be used, could maybe use a submit button) will populate a table below the input box with all the information for that name, in many cases this would be multiple rows.

I'm trying to dynamically populate a drop down box with fields from a SQL Server Database, but I'm having some issues. I am able to get it to work well with only one field, but I need to get display two fields in the ddl. I've seen that you can do it in the command statement, but I have two different data types and I think that causes it to throw an error: Conversion failed when converting the varchar value 'This is a Title' to data type int.
here is my code:

I am going to add a computed column to a stored procedure that will combine the last and first names of all of the customers in my db. This will be used to populate a drop down list that will allow the user to select a customer so a new record can be entered for that customer.
I was planning on creating this computed column on the procedure that returns all of the customers and all of there information. My db is small so this shouldn't be a big deal, as far as overhead. This doesn't seem like the best approach if the app was using a much larger db. It would unnecessarily return a lot of extra data and make it slower.
I'm curios when a procedure that's dedicated to returning just the customer's first name, last name, and ID should be used, instead of one that returns everything. There are a number of variables that could make this hard to determine, such as number of rows and columns. I wanted to try to get an idea of a cut off point or rule of thumb on this, if possible.

This is my first post as a newbie to asp.net.
I am in the process of creating a "news system", you can add, edit and delete news. The news items can be entered into the SQL database and you select a category where you want the news item to go into.
What I want is when someone comes to the "Edit" screen, they have a drop down list and what that does is allows you to select a category for you to edit news items from, so rather than at present having the "Edit" page display all the news items, I want people to be able to choose a category that they can edit news items in.
So far my edit page has a datagrid with the following code:

I've got a drop down list that I want to populate with items from a SQL Server database, which I did successfully, but I can't figure out how to write an if statement that will clear the drop down list based on a selected index and repopulate it with data from another table. The drop down list is inside an update panel that auto posts back.
Basically I want to allow the user to choose an item, but rather than populate another drop down list control, i just want to repopulate the current one with new data.I'm guessing that if I want to get data from more than one table the code below isn't going to work for me. Could I get the data from all the tables at once and store each table data in its own variable until I need to use it? (Each table will have under 10 items, in 5 tables.)
Here is the code to get the data from the database:[Code]....

I have a drop-down list that is wired up to a datasource from one table to retrieve a Vendor ID and Vendor Name. This ddl is outside a FormView that is wired up to a datasource containing Vendor contracts.
When I choose a Vendor from the ddl, I am able to populate a textbox outside of FormView with the Vendor ID from the ddl. However, what I need to do is populate a textbox within FormView with the Vendor ID. FormView is in Insert Mode by default since my page will be used for Adding Contracts only.

DateTime ExpMonth = Convert.ToInt32(ddExpMonth); ---- DropDown(user selects a month)
DateTime ExpYear = Convert.ToInt32(ddExpYear); ---- Dropdown(user selects year)
Datetime ExpDate = ///// I want this part to be saved as Datetime 02/2012
How is this possible?

I have 2 button links and 1 text like this:
Previous JULY Next
Every time i press Previous, a variable mymonth subtracts 1 , and when if i press
Next , the variable mymonth adds 1.
Previous LINK: <%# mymonth - 1 %>
Next LINK: <%# mymonth + 1 %>
All the schedule from the DB is shown, using the following SQL:
SELECT DISTINCT day(mydate) FROM schedule WHERE month(mydate)=" + mymonth + " AND year(mydate)=" + myyear + " ORDER BY day(mydate) ASC"
But my problems are:
- i want to show 3 months backwards from th actual month
- when mymonth is 1 (January) 2011 for example, it would show December, November and October from 2010
- If for example, we are in JULY, it would show until APRIL backwards, and when on APRIL it wouldnt show the PREVIOUS button.

I have a textbox that gets the date from an AJAX Calendar extender. What I need to do is extract the "month," "day," and "year," and put them into seperate string variables to use in my code to do various things based on the month, day or year respectively.
Here is what I have so far:
