Oct 29, 2010I've created a dropdownlist that pulls from a SQL table with 241 rows. For some reason, the list only shows 168 rows? What am I doing wrong?

View 4 RepliesI want to create a page on which the website's sponsors are displayed. The information about the sponsors is coming from the database via an ObjectDataSource, and I'm retrieving an Image (company logo), the name of the company, and a url to the company's website. Each Image (logo) is of the same height, but of varying width. I want each Item to be formatted so that the Image is on top, and underneath is a centered hyperlink with the name of the company.
This all seems pretty straightforward ... now for my problem: I want to display as many of these on the page as possible. Essentially, start off horizontally and fit as many as possible on each row. A DataList or Repeater with RepeatDirection=Horizontal doesn't quite do what I want as I don't want to have a fixed number of columns.
Is there an easy way to achieve this, or do I have to manually add up the width of each item on an ItemDataBound event, and then somehow move to the next row when the maximum width is reached? In addition I have to deal with the fact that the width of my Item is the maximum of the Image width and the text underneath.

View 5 RepliesI need to bind my dropdownlist to my dataset that is returning application specific text values. But for purposes on that page, i need to assign the value to each one starting at 0 to the number of items returned from my dataset..
Example, if my dataset only returns 1 item, the value of that item needs to be 0
[Code]....
If my dataset returns 4 items, the value of those items needs to be 0 thru 3

Is it possible to assign values like that to a dropdownlist from the code behind?

View 1 RepliesI have a html.dropdownlist on my webpage as follows: <%=Html.DropDownList("MyDropDown", Model.Data, new { @class = "dropdown"})%> I am populating the dropdown with ~80 items. The issue is that when I click the dropdown the list of items is rendered from the top of the screen to the bottom of the screen. How can I set up the dropdownlist so that it only displays a maximum of 20 items when the dropdown menu is clicked (i.e. user needs to scroll down to see items 21 - 80)?
I was anticipating (!) that there would be a html.dropdownlist property to control the number of displayed items that would allow something like the following e.g.: <% =Html.DropDownList("MyDropDown", Model.Data, new { @class = "dropdown", rows ="20"}) %> From research I have been doing on the msdn website it appears that there is no such property and that each browser has its own rules of how many items are displayed in a dropdownlist (?).

View 2 RepliesI have a gridview, in which i placed checkbox as Itemtemplate. My need is to restrict the user from selecting more than 'N' number of selections.
Eg: Gridview contains 50 records, that means 50 check boxes.
Max permitted selections: 10.
After the 10th checkbox selection, user should be prompted that..
"No more selections.. blah blah... "
Should i go for looping through records.. or is there any better way..

View 1 RepliesI have an ambitious requirement for an asp.net 2.0 web page that contains a table (gridview), and each row in the grid contains 6 select (dropdown) controls for data entry. The number of rows that will be displayed is dependent upon the user's search parameters, which are specified in another area of the page. Unfortunately, with the default (and even basic) search parameters specified, the grid could contain several hundred rows. I've noticed that the browser, in this case IE8, starts behaving rather erratically once I reach a large number of rows -- no documented evidence for the number of rows where this begins to be a problem. For example, trying to view the source of the page results in a message from IE stating that there was a problem with the page that forced the browser to reload it, and I never get the source. Obviously the page loads and renders rather slowly also.
I know that my solution is probably going to involve paging the gridview such that it only displays 20 or so rows per page, and I'll have to write code to handle the saving of changes in the dropdown values when the user changes pages. I can probably turn off viewstate on the gridview also. However, the question I really want to pose is this -- has anyone seen a documented rule indicating the maximum number of input controls that an HTML browser form is supposed to be able to contain? I could not find anything on the Internet after doing a search, and I suspect the answer may be whatever the browser can handle based on the machine configuration it is running on. Any rules of thumb you use?
one of our programmers is having an issue with a asp.net app. i had him rebuild and recompile the app to the network share on the staging server and received the same error. i even deleted the files in this folder
(C:WINDOWSMicrosoft.NETFrameworkv2.0.50727Temporary ASP.NET Files). to make sure that the server was not the issue i installed it on another server and received the same error. i found a article on msdn that states that its a source code issue. Compiler Error Message: BC30041: Maximum number of errors has been exceeded. Source Error:

it's a multiline TextBox the MaxLength property does not work. At the moment I only see the option to use a CustomValidator with checking TextBox1.Text.Length on server side and perhaps in addition some Javascript client side validation.But isn't there a simpler way to do this, using the standard ASP.NET validators (RegularExpressionValidator, RangeValidator, CompareValidator, etc.)
View 1 RepliesI have a PDF document with a number of text fields, several of which have a maximum length - namely, a maximum number of allowable characters. Is there a way using iTextSharp to determine this setting? Here's the code I have so far:
Dim reader As New iTextSharp.text.pdf.PdfReader("Foobar.pdf")
Dim inputFields As IDictionary(Of String, iTextSharp.text.pdf.AcroFields.Item) = reader.AcroFields.Fields
For Each key As String In inputFields.Keys
Dim PDFFieldName As String = key
Dim MaxFieldLength As Integer = ???
...

I need to set MaxFieldLength to the number of allowable characters for the current form field being iterated over.

I developed a web site using Sybase PowerBuilder V12.0 Classic and the output is deployed and converted to ASP.Net (ASPX) web pages.The Database connection is configured and used properly as the data is displayed in the web application using DataWindow Objects and is a direct connection with sybase Database Server using Dsedit Tool and No ODBC is used.I edited The Sybase Databse configurations related to remote servers and connections to be more than the default value which was 25 although the real number of users will not exceed that in the same time.Recently I received an error message when some users connected to the web site and after making valid logins:-The Error Message is:-Maximum number of connections already opened ct_connect(): user api layer: external error: The maximum number of connections have already been opened.
I am confused about the causes of that error as I think I had made all configurations needed and I checked evey option and setting related to the Number of Connections in The Sybase Database server, The Application Deployment Settings in Sybase PowerBuilder V12.0 Classic, and The IIS Settings.I use Windows Server 2003 and the IIS version is 6.0 in the Web Server.
I experience a strange issue with DropDownList today.
It is bind to SqlDataSource which produce about 1500 item. SqlDataSource working properly and no mistake in SQL.
When i bind it to a DropDownList, first item automatically selected on load. But if i try to select other items, DDL never renders. Width of DDL shrinks to zero. But if i use UP and DOWN arrows, i can go through items which appears on the first line of DDL. Shortly, DDL never render a LIST of data for me as it is supposed to do.
If restrict the data as "SELECT TOP 100 SupplierName blabla..", the DDL works properly. Is there any data limit in DDL? 1500 line is massive for DDL?
With the same SqlDataSource, ListView control is working succesfully.
Here is my ASPX
