I have a FormView InsertItemTemplate which has a databound dropdownlist. The dropdownlist displays a list of names retrieved through a SQL Server stored proc. The user has an option to add a new name to the database by clicking a button next to the dropdownlist. Clicking the button fires a javascript function, which opens a modal window. This "popup" window is where a new name and other pertinent data is entered. When the modal window closes the dropdownlist needs to refresh in order to display the new name (which was just entered in the modal window).

What is the best approach to refresh the dropdownlist? Where and when should a refresh occur (in what event)? I've searched for a solution and found many but none worked for me.

Thanks for your help!

How to export images to Excel/PDF/WORD in ASP.NET using VB?
I can only export the gridview to excel, but not images.
Help will be greatly appreciated.

Thanks

This has nothing to do with ASP.NET, working with different formats is a pure VB task. You export to office using the Microsoft tools, and to PDF by buying an SDK.

I Do not want to waste my time talking to you.
So DO NOT write anything in my questions forum!!!

Thanks

I have to agree with Yusef. If you don't know how to do this, a forum is the wrong place to ask . You could pay me to write it for you, or you could do some research and ask specific questions when you get stuck, but 'how do I write xxx' is not a valid question, nor is a forum a place to expect an in depth answer to so broad a question

OK, Since i haven seen in the FAQ column that this web site is free to share knowledge, so i ask questions here!
if i had known that it was not a free forum, i would NOT posted a questions here.

I will go and asked for other programmers for help since i do not think this web site offers a good service nor is helpful.

I will not post questions again and recommend my friends to see this web site since this fourm is the most terrible and unhelpful forum i have ever seen!!

Hi friends i have one serious problem i m unable to pass an array like string[] seatLayout=new string[100]; from one page named SelectBus.aspx to PassDetails.aspx.....i m stuked there? i need to pass array from one page to another. Can any one please help? Cry | :((

well there are several ways you can pass data between pages, Query String, Session variables etc. string[100] is potentially huge data, depending on the content of each element.

Why don't you persist the data to either database or file and pass a handle from one page to another

page1.aspx: Save string[100] to database then call page2.aspx?id=some_id

Your first question is, why do you need to pass this array ? You should probably store it in a DB, and pass the id used to pull it from the DB. Having said that, you could concievably place the array on the URL, or use the Session.

simply i m given it as [100] but i need only 5 to 10 thats all......because in one page user will select seats in the bus for reservations i need to pass these values to next page thats all...........

Hi,

You can Use Querystring for Passing Array from one Page to Another page.
I hope the following Sample Code will Help You.

Let's start by creating the array in CreateArray.asp

'Create an array that contains
'the days of the week
Dim aWeekDays(6)
aWeekDays(0) = "Sunday"
aWeekDays(1) = "Monday"
aWeekDays(2) = "Tuesday"
aWeekDays(3) = "Wednesday"
aWeekDays(4) = "Thursday"
aWeekDays(5) = "Friday"
aWeekDays(6) = "Saturday"

Now, to store the array contents in the querystring, we will loop from LBound(aWeekDays) to UBound(aWeekDays). For each element, we'll add an item to the querystring, having the array name, an equals sign, and then the value of the particular array element.

'Build the querystring
Dim iLoop, strQueryString
For iLoop = LBound(aWeekDays) to UBound(aWeekDays)
strQueryString = strQueryString & "WeekDays=" & aWeekDays(iLoop)
strQueryString = strQueryString & "&"
Next

'Cut off the last character
strQueryString = Left(strQueryString, Len(strQueryString) - 1)

'Now, create the actual hyperlink
%>

ReceiveArray.asp

but how to retrieve the elements in the next page?????? Frown | :(

Hi, I would like to develop an application in ASP.NET (using c#) which would consist of an image of a football pitch and icons, each having a player's name.

The user will use the mouse to drag an icon image (which represents a particular player) and drop it somewhere on the pitch image. Finally the user will save it, for it to be displayed somewhere else.

Something similar to this: http://news.bbc.co.uk/sport2/hi/football/score_on_bbci/7631245.stm[^]

Anyone got a solution or tutorial?

Thanks Smile | :)
