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.
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 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 insert checkbox text only if they are checked. .. how to do that ..
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load TextBox1.Text = Request.QueryString("txt") Dim splitted As String() = TextBox1.Text.Split(",") For Each id As String In splitted Dim ctrl As Control = Page.FindControl("checkbox" & id) If Not ctrl Is Nothing Then Dim chkbox As CheckBox = DirectCast(ctrl, CheckBox) chkbox.Enabled = False Dim arrList As New ArrayList() 'populate the list with some temp values arrList.Add(CheckBox1.Text) arrList.Add(CheckBox2.Text) 'databind the list to our repeater Repeater1.DataSource = arrList Repeater1.DataBind() End If Next End Sub
This code will add all checkboxes whether it is checked or not !
so that only checked checkboxes would be added in array list
the problem is actually in the subject. I have custom control that uses treeview. The control is added dynamically. Nodes for this treeview are populated on demand. Treeview nodes can be checked. I recreate this control on page load event, but still CheckedNodes is empty if checked nodes were added dynamically (added on demand).
On adding items in it ,shows an error: "Dropdownlist does not allow multiple selection."But when i tries to print the selected item it shows null exception.
I have a asp.net list box control in which i populate items using Jquery by using some code like .. $("#MylistBox").append("<option value='somevalue'>Someitem</option>
dynamically . but in code behind when i use MylistBox.Items is always showing Count 0 no matter how much items add.
I have a repeater that repeats a bunch of questions. Each questions has answer options, therefor each RepeaterItem has a RadioButtonList.
I bind to the repeater on page load if the page is NOT postback. And in the repeater Item DataBound event i bind to the RadioButtonList.
Then wen I click on the submit button, I want to loop through all the controls and get the selected value of each list. But for some reason every single Item is False when I check is selected. Or -1 if I say selectedIndex.
This is the code I use to loop through the items on the button click.
[Code]....
I have also tried printing out the text values and whether its selected or not. It gets all the text values correctly, but always say False for selected or -1 for selectedIndex.
And after the postback nothing in the list is selected. So I think it has something to do with the way its bound, but I am not sure what I am doing wrong.
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 CheckBoxList in my page, with the DataTextField and DataValueField attributes set, is there an attribute that I can use to specify a property that indicates if it should be checked?
I'm hoping to just set the datasource, and not have to have any code behind to set the checked property. Possible?
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'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 the Grid with Check box. here i want the Total of checked rows "CheckAmount".checkamount is one column in the grid i am able to getting the Total in single page(grid page=1). i am not able to getting the total of "CheckAmount" in multiple pages like (Grid Page=1 and Page=2 ) when i go to the second page i am not getting the 1st page Total.
I got a list of checkboxes on my form, and a jquery script that catch a button click to get all the selected items (in an array) and post to a controller action.
This is my script: (yes A, looked at your sample but cannot get this to work)
[Code]....
That alert will print out correctly (like 1,3,5).
However when the above post hit my controller action, "selectedInvestments" are null, which I can't figure out why (back to my tekpub jquery videos, can't go on like this)
I have a selection list that is generated dynamically, it lists a number of checkboxes that are based on an end-user editable table, as such I have no idea what data, or how much, might be contained in this table and how many checkboxes or what they might contain, other than the primary keys of the table. The user will select the checks they wish to see, and then control is passed to another page via PostBackUrl. The second page has to figure out which records to show (build it's where clause) based on the checkboxes checked in the previous page.
So, my problem is several-fold. First, asp:CheckBoxes don't have values. This can be worked around by a number of methods. Right now, i'm using a placeholder and dynamically creating the checkboxes in the ItemDataBound event of the DataList. I set the ID to "CheckboxKey1Key2" (where Key1 and Key2 are the primary keys of the check items). Second, I have to walk through the controls of the PreviousPage to dig out all these values. That in itself is also a pain, but doable. Now, my thinking is to build the where clause of my Linq2Sql query based on the keys I got from decoding the checked checkbox names. This all seems like a lot of jumping through hoops for something that shouldn't be this difficult. Am I missing something? Does anyone have any better solutions?
have a grid view with chkbox column and sme other columns ,whn i clk on the submit btn the page redirectsto next page and in the new page load i need a grid view of previous page but only with the items i checked and some extra columns .
