DataType for DropDownLists, ListBox, CheckBoxes and RadioButtons

Posted By:      Posted Date: September 20, 2010    Points: 0   Category :ASP.Net


When 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.

What do you think?

ListBox tricky to set in a DataGrid/GridView

Listboxes are very tricky to set selected items in grid - there is no real nice way to do it. It would have been great if Microsoft included a property that accepts an array or comma separated values - or anything! But they only allow each item in the list to be selected individually. The way to do this in a grid is a bit messy, but it is fairly simple to implement. When a row is created (as per the event), select the items of the listbox as per the datagrid source data:

ActiveX and Visual Basic: Enhance the Display of Long Text Strings in a Combobox or Listbox


The combobox and listbox controls in Visual Basic have no built-in support for displaying text strings that are too long to fit in the visible area of either control. This article describes several techniques to improve the readability of long strings in each control. The first technique uses tooltips to display a combobox or listbox item. The other techniques, which use various Windows APIs, include adding a horizontal scrollbar for a listbox and determining the necessary width of the longest string given the font attributes of the text. The required steps are described for both comboboxes and listboxes.

setting scroll position for a ListBox


I have a ListBox control showing 10 rows.  I have 30 rows total in the listbox.  How do I programmatically adjust the scroll to show the last ten rows?

Some sources have suggested that I set the SelectedItem.  But I am already making selections (myListBox.Items[28].Selected = true, myListBox.Items[29].Selected = true, etc); the listbox scroll is positioned on Item[0] not the first selected item.  I have also tried setting myListBox.SelectedItem in addition to the multiple selection just mentioned but that does not have any affect either.

What it does is going to the item i type on the textbox.
It will not filter the listbox so it will contain the specific matches.
I was reading for autocomplete but i don't seem to find this 2 way usage.
I was also reading this article:
But i'm completely lost on how i can implement it.
Any ideas?

How to reference a listbox from a procedure


I have a listbox that gets loaded from a couple of different places on my web form.

I would like to put the code to load the listbox in one place, rather than have two copies of it.

The problem is, I can't figure out how to reference the listbox control successfully from within a procedure.

Would anyone know how to do this?

My code looks like this:

private static bool LoadSubscriptionListBox(System.Web.UI.Page Page)
        bool bReturn = false;

        // Clear the listbox

        // Load the listbox



listview 3.5 bind dropdownlists edit item template VB.NET


I am trying to do this with many issues of data binding doubling the amount and not setting selectedValue on dropdownlist. I have read some posts and they help but I am missing a crucial piece. My problem is that my dropdownlist is doubling the amount of records for the dropdownlist. Instead of "YES;NO;SELECT A VALUE", I am getting "YES;NO;SELECT A VALUE;YES;NO;YES;NO". My database is correct with the UPDATE part but the rebind after update is failing horribly.

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        If IsPostBack Then
            If Session("ACTIVETAB").ToString() = Session("SUBCONTRACTSATABNO").ToString() Then
            End If
        End If
    End Sub

    Public Function loadlookups(ByVal id As String, ByVal e As System.Web.UI.WebControls.ListViewItemEventArgs) As DataTable
        Select Case id
            Case "ddlCertReceived"
                dt = GetLookupTable("SubcontractsA", "Sub 1 Cert Received")
                Dim ddlCertReceived As DropDownList = _
                CType(e.Item.FindControl("ddlCertReceived"), DropDownList)
                ddlCertReceived.DataSource = dt
                ddlCertReceived.DataTextField = "lup_text"

2 Databound Dropdownlists... how to bound data to the 2nd one?


hi there,
I have a database with the following table:

Table Job {
    nvarchar(50) JobID,
    nnarchar(50) JobName,
    Bit/Bool     Active;

I'm trying to build an .aspx page with two dropdownlists:

  1. The first will display the JobIDs of all Jobs available in the Database (I have done this part and it's working)
  2. The second will display by default the value "Choose Job first".

  What I'm trying to do is: Once the user chooses the JobID (step 1), the page should reload and the 2nd dropdownlist should display the following:

  •  if the value of the field "Active" of the corresponding JobID is '1'(i.e, the Job is already active) -> then the Dropdownlist should display "Already active" and "Deactivate" values
  • if the value of the field "Active" of the corresponding JobID is '0'(i.e, the Job is inactive) -> then the Dropdownlist should display "Activate" and "Already Deactive" values.

This is my code:


<div class="formField JobSelect">
<asp:Label ID="lbl_J

Checkboxes in Datagrid


This morning I posted a question w.r.t Radio Buttons, but the requirement changed so I'm posing a similar question.

I want to have a checkbox in a datagrid.

Suppose I click on one of the checkboxes and then realize i need to click on another, the screen has to automatically uncheck the previously clicked checkbox and then check the newly clicked checkbox.

In other words I need to clear previously checked checkboxes and check the recently clicked checkbox.

Also, I need to update a label in the page with a value associated with the row of the checked checkbox.

I should not be using a javascript to do this.

Any help in this regard would be highly appreciated.

jQuery modified ListBox not posting back modified values


Hi everyone,

I have an ASP.Net ListBox that I'm trying to populate via jQuery, using the following snippet:

        $("#MyList_btnAddAll").click(function(e) {
        $('#MyList_lstAll option').appendTo('#MyList_lstSelected');

The code has two ListBoxes in fact, one a "source" and the other a "destination".  As you can tell above the ListBoxes are MyList_lstAll and MyList_lstSelected.  These are rendered in the browser as <select> elements, as you'd expect.

The jQuery is working great, the items are moving from one ListBox to the other, the DOM is updated but when I submit this form (not using jQuery), the ListBoxes don't reflect this change on postback. 

I realize my modifications via jQuery aren't available in ViewState but I thought since the DOM was updated these changes would be part of the postback data?  But in the codebehind after postback the ListBox contents haven't changed.  Does anyone know what might be going on and what I can do about it?  Many thanks.
