MVC :: DataType For DropDownLists, ListBox, CheckBoxes And RadioButtons?
Sep 21, 2010When using a DropDownList, ListBox, CheckBoxes, RadioButtons what data type do you suggest to hold the values?Usually the values are 1, 2, 3, etc. It makes more sense to me and usually these are the id's of the items.I tend to use the following:
1) When only ONE option can be selected I amke the property of type INT? (Nullable int). This is for when no item is selected it makes more sense to me to check if it's null then 0. And in most validation frameworks there is a null validator.
2) If MANY options can be selected then I use INT[]. Then I can check for null or count the selections.
Javascript - Add / Remove Items From One ListBox Control To Another ListBox Control?
Oct 10, 2010I'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.

Web Forms :: Fill Listbox Using Webservice / Via Control
Mar 25, 2011I 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.

Forms Data Controls :: ListBox, Array List / Update The Listbox Content?
Mar 26, 2011I 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
=======================================
Sub UpdateSwap(ByVal valueA As String, ByVal ValueBAs String, ByVal ValueC As Integer, ByVal ValueD As Date)
Web Forms :: Adding Item To Listbox From Another Listbox Taking Way Too Long?
Mar 4, 2010I 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?
