Javascript - Add / Remove Items From One ListBox Control To Another ListBox Control?
Oct 10, 2010
I'm moving itmes from one ASP.NET ListBox control to another ListBox control from client-side. It works on the client-side but when I tried to count items in destination ListBox on the server-side, it's always nothing. Below, is the jQuery code used to add/remove items from ListBox control.
[Code].....
I know that we can add/remove items from ListBox from server-side. But I'd like to get it done from client-side. Why there isn't anything in the destination ListBox when counting the items from the code-behind, eventhough the items are added from the client-side already.
I am working on a screen where in it has a typical 2 listboxes & 2 buttons(add/remove), so when these buttons are clicked the items have to move from one listbox to another. its all working fine with javascript.but the issue is, I am not able to get the items of the 2nd listbox in the codebehind. I tried with html & asp.net listbox controls. I even tried to access the listbox using Request.Form["ControlName"] - which gives a null value.In the listbox1 the data's are coming from database.The data's choose from listbox1 will be moved to listbox2. And again i have to update this data to one of database table.
I have 2 ListBoxes. 1st SelectionMode is Multiple. Once I select many options from 1st ListBox I can copy it in ListBox2 but i Unable to remove it.
Code :
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click For i = 0 To ListBox1.SelectedItems.Count - 1 ListBox2.Items.Add(ListBox1.SelectedItems(i).ToString()) ' ListBox1.Items.Remove(ListBox1.SelectedItems(i).ToString()) it is not removing. Next End Sub
I have a ListBox which is bound to a list of data items.
Now I want the user to be able to filter the items shown in the ListBox based on the search expression typed in the TextBox. For each character typed in the TextBox, the ListBox items should change to show only the items matching the search expression.

How to set the height of an asp.net's Listbox control dynamically equal to the height of the table cell in which it is present. Or is there any way to d ock the listbox control inside a table cell
I need to create a reusable custom control,which is like a form containing a listbox and some fields.The fields can be either textbox or combobox as needed for different applications,which can be selected on the property of the form onwhich page that i am using it,also i needed to specify the number of fields in that property.And also need place 3 buttons below for edit and delete the selected item in the listbox and a button to save.Data will be binded from the database as needed for different applications.
tell me with code how to create it using asp.net server control in C#.
I am designing a program that will let me enter the name of an item to swap and adds the swap to an array list when a button Add is pressed. Once the item is added to the array list a Sub Procedure should be called which displays the contents of the array list in a list box.
The system will also allow me to remove items from the array list using a Remove button
followed by updating array list.
I have done some part which puts item into the listbox1 which i named lstSwapList.I would need some assistance on the Sub Procedure to display the Value or Description on the other listbox2 which i have also named lstContent,if a value is selected from the listbox1.
I would also want to know how to update the Listbox content,However i hv added a sample of the way i guess it may be.
Any complete solution from anybody on the Sub Procedure and the Update Swap procedure will be greately appreciated.
The script below is what i have done so far.
Partial Class _Default Inherits System.Web.UI.Page Protected Sub lstContent_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles lstContent.SelectedIndexChanged End Sub Protected Sub lstSwapList_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles lstSwapList.SelectedIndexChanged End Sub Protected Sub btnAddSwap_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnAddSwap.Click Dim SwapValue As String = "Sixty Pounds" Dim Counter As Integer = 8 Dim SwapN0 As Integer lstSwapList.Items.Add(SwapValue) lstSwapList.Items.Add(Counter) lstSwapList.Items.Add(New ListItem("300", "1")) lstSwapList.Items.Add(New ListItem("ASP.Net", "2")) lstSwapList.Items.Add(New ListItem("Programming", "3")) SwapN0 = lstSwapList.SelectedValue For Counter = 0 To -1 SwapN0 = lstContent.Items.Count Next End Sub Protected Sub btnDeleteSwap_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnDeleteSwap.Click lstSwapList.Items.Remove(lstSwapList.SelectedValue) End Sub Protected Sub btnUpdateSwap_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnUpdateSwap.Click End Sub End Class

I'm trying to auto-populate a listbox of zip codes from a database table state_zipcode_plans based on the state a user selects from the previous listbox. I'm getting the error: Must declare the scalar variable @state_code.
I have two list boxes, one has a list of available users (about 1500 items) and the other is blank. There is a button to add the seleted items from the first list box to the second one. Both of these listboxes are within an update panel and for some reason it takes over 20 seconds for the items to show up in the second listbox.
Is this normal? Is there an alternate, faster way of doing this?
I have a number of dropdownlists which use cascading dropdownlist / webservices. All fine. Now user wants last dropdown to be multi-select. So I want to replace the last dropdownlist with a listbox. But there is no cascadinglistbox. I'm looking for a straight-forward solution if possible. Either how to fill the listbox with the existing webservice which fills the last dropdownlist, or - is it possible to use the contrents of the last dropdown as a datasource for the listbox? I thought maybe hide the last dropdown and loop through its contents to fill the listbox.
I expected that clicking on different items in the control would cause each to highlight, but when I click a new item the highlight moves to that item, and previously selected highlight is removed. Is this how the control is supposed to work?
I have a simple custom control that boils down to a label and a listbox. Selections in the listbox are reflected in the label as comma separated values. My question is what is the best and simplest way to make the page developers experience of working with the custom control exactly mimic the experience of working with just the listbox - when it comes to working with data. For some reason it feels wrong to simply create mirrored properties in the custom control and forward their values to the internal listbox. A small, perhaps unrelated complication is that the final product has to play nice with the forms collection due to the nature of the host application.
