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.
i want to show the arrayliust items in the listbox, for that i had stored some data in array list, and now i want that if i gv any id which is in the array list its corresponding details are displayed in listbox. I had two fields ID, Name, and when i give id its corresponding name should be shown in list box.
i want to create a arraylist which will able to store user info like (username,machineIP,port ) for each user in the list & retrive this data when needed . any one tell me how i can do it or any alternative way without database or xml file.
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?
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 am dealing with a problem that i have to make decision based on the number of items in a cascading dropdownlist. unfortunately this ajax toolkit control does not expose a Items collection.how do i count the number of items in this control ?
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 (?).
How can i get the number of a listview records (or the index of the last record) from within the ItemDataBound event ? I would like to hide one of the controls in the last record, how can i know if the item is the last one ?
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.
I follow the following link for add dropdownlist in gridview.Adding Dynamic Rows in GridView with DropDownLists in ASP.Net..In this template field the drop down list contain 500 items how can i search the paticular item
i want to apply color to selected number of items in checkbox list and seleted number of items in drop downlist for e.g color red for few items and black (default). I have a bit value set in data base so if bit is set to 0 then red and if 1 then back.
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.
vb Code: Function FindCapital(ByVal CountryCode As Integer, ByVal CountryName As String) As StringEnd Function
And later on when i call the function I want the function to be able to show all the available CountryCode and CountryName values, so I can select the one I want. I'm not sure how I can do that or if it's possible.
