How To Get An Arraylist To Display Only Predefined Number Of Items
Jun 28, 2010
ArrayList list = acontroller.ListForDisplay(articleModule.expireDate);
How can I get the "list" only display 10 items?
I don't want to set the number to display with stored procedure.
I've got another unrelated question, - from performance perspective, is it more efficient to sort data in stored procedure than sort using "icomparable" after I got a list of data into an arraylist? (30,000 record to sort.

I'm trying to remove the first 5 or "a predefined number" of items from my Arraylist. I tried the following but I noticed It removed index 1,3,5 because the each time an item is removed, the index 1 will become 0. remove the index 0 a number of times?
for (int i = 0; i < numberToSkip; i++)
{ newList.Remove(newList[i]); }

I have a gridview where there is a column of checkboxes for the user to check on for the products he/she wants. After checking, they will have to click on a button. for every checkbox that is checked, the result will be stored in an arraylist. after the button is clicked, the label will show the count of the number of objects in the arraylist, which is the number of items that were checked. However, it appears that objects are not being added to the arraylist. What's the problem? Below is some portion of the code for more understanding.

How do you go about removing multiple items from a array list?
I'm using the RemoveAt() method to remove but doing that resets the ArrayList's index which cause me problems if the user selects to remove 1 & 3 out of a 3 list array since once it removes 0 the array list now just has 0 & 1.

Here is a vague sample of what I'm talking about..

I'm not experienced enough with the foreach statement to quite figure out what I'm doing wrong here.

I have a web user control with DataList control in it. In my .aspx page, I have a report header, an empty panel as a place holder, a report footer.In my .aspx.vb file, I'll loop through a list of departments. Within each department, I'll load a label to display the department name and the user control for the data, and add both the label and user control to the panel. So there are two variables:
the number of departments and the number of records in a user control.
Now I need to display the current page number and the total page number in the report footer. Is it doable? How? I'm thinking of this approach: declare a page variable count, count the number of department name labels and the number of records in a user control. When the total count reaches a number, such as 20, I'll break the page. This way, I can get the the page current number and the total number of pages. But how to add a page break to an asp.net page?

For example, we have 19 items on the repeater datasource. And we wanted to separate them using by 5 items.
It's like
01 02 03 04 05 <br />
06 07 08 09 10 <br />
11 12 13 14 15 <br />
16 17 18 19
How are we going to do this in asp.net repeater?

Using Microsoft built-in jquery files, when counting numbers of checked checkbox, the jquery-1.4.2.min.js cannot count the correct result ,however, the version jquery-1.3.2.min.js gives out the correct one, why?
$("#check").click(function () {
var nameSports = new Array();
var i = 0;
$('input[name=selector]:checked').each(function () {
nameSports[i] = jQuery(this).val();
i += 1;
});
if (loopCounter != 0) {
alert(i);
}
});
<input type="checkbox" value="1" name="selector">
<input type="checkbox" value="2" name="selector">
<input type="checkbox" value="3" name="selector">
<a id="check">Check Items</a>

I 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 (?).

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

I 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
[Code]....
Is it possible to assign values like that to a dropdownlist from the code behind?

The "FilePath" and "AttachmentID" fields are being set correctly in the grid, however, the CheckBox control is never set correctly; it is always unchecked.
My question:
How do I get this CheckBox field set from C# as I'm creating the new row?
P.S. I am not sure if I am creating the row correctly in the first place.
