Listbox Control Not Preserving Selected Item On Button Click

Mar 26, 2014

Ok so I have two listboxes on my page one for users and another for cases. For some reason the users listbox preserves state, but the cases listbox doesn't.

They're both set EnableViewState= true

Code:

<asp:ListBox ID="ExistingUsers" runat="server" Width="45%" Height="189px"
CssClass="createdusers" ></asp:ListBox>
<asp:ListBox ID="ExistingCases" runat="server" Width="45%" Height="190px"
></asp:ListBox>

I tried setting them both to autopostback, but that didn't work. The users listbox would preserve the selected item, but make it the first viewable item in the list. The cases listbox still reset the selected item to the first.

My page load:

Code:

'....
If Not Page.IsPostBack Then
''Sort later.
Dim i As Integer = 10
For Each usr As String In AttRoleProvider.GetUsersInRole("Role1")
Me.ExistingUsers.Items.Add(usr)

[Code]......

Javascript - Scroll To First Selected Item In ListBox

Nov 17, 2010

is there an easy way to scroll an ASP.Net ListBox automatically to the first selected Item? The ListBox has SelectioMode="Multiple".

<asp:ListBox ID="LbSymptomCodesEdit" CausesValidation="true" ValidationGroup="VG_SAVE" Height="100%" Width="100%" runat="server" SelectionMode="Multiple"></asp:ListBox>

The ListBox is in the EditItemTemplate of a FormView inside of an UpdatePanel. jQuery is possible but it would be great if there would be an asp.net serverside(or Ajax) way to achieve this because i don't want to use more client scripts than really needed(and this is only a nice to have).

Update Textbox Through Selected Item In Listbox?

Mar 11, 2011

In ASP.NET I have a dropdown with some items in it, I have a button and a textbox. I am subscribed to the SelectedIndexChanged event of the dropdown where I pass the new selected index of the dropdown to a struct that converts it's index (via enum) to a string. That string is then gotten through a property in a class to put into the textbox.

[Code]....

Now the problem I have is that, when you click it (the button) the first time, the action get's updated with the current action selected in the listbox, but then when you click the button again WITHOUT changing anything in the listbox, the textbox shows the zero'th item in the textbox, (seems to reset), although it actually hasn't changed at all.

I'm guessing this might have something to do with the postback caused by the button click, which resets the state of the global or something, but I'm not sure. Why is it being reset while the dropdown box is still as I set it the first time?

Web Forms :: Listbox.Selected - Duplicate Item Error

Nov 4, 2010

I have built one of those 2 listbox things where the items in the left textbox can be selected and moved to the right list box. The items in the list can be thought of as tasks (like Raise Invoice, Call Client, Deliver goods etc) The rules of this are that the item you move to the right box remains in the left box. Reason being, you are allowed to add the same item from the left to right as many times as you like. An example what the list on the right might look like is this.

Raise Invoice
Call Client
Deliver Goods
Installation
Call Client
Finalize Deal

Now I have added the feature to select an item on the right and hit the UP button, to move it up in the list. For example I could select 'Deliver Goods' and hit the up button. (the down button works as expected)

Raise Invoice
Deliver Goods
Call Client
Installation
Call Client
Finalize Deal

If i select the 2nd instance of Call Client and hit the up button,

Raise Invoice
Call Client
Deliver Goods
Installation
Call Client
Finalize Deal

This is what happens.

Raise Invoice
Call Client
Deliver Goods
Installation
Call Client
Finalize Deal

My code that loops though and does the move relies on the item.selected property to find which on I have selected. (obviously)

[Code]....

Despite having the items at the bottom of the list selected, the .Selected property is true on the first instance of the item that happens to have the same .Text and .Value.

Web Forms :: Displaying Data From Selected Item In Listbox

Oct 13, 2010

I have a asp.net web form in which I display registered customers in a listbox. In the listbox I can choose one customer, and click a "Show data"-button. That should display all registered data about the chosen customer in textboxes next to the listbox. This doesn't work and I haven't been able to find where the error lies. Instead of displaiyng the data in the textboxes the error message in: LabelNoCustomerChosen is displayed. Could it be that the program doesn't find the customer ID? The string that is displayed in the listbox looks like this: ID Lastname, Firstname

Using Javascript To Detect When User Has Selected Item In Listbox?

Mar 16, 2010

I am developing an ASP.NET web application that incorporates google maps. I have an ASP.NET listbox on my page which contains a list of items. When the user selects one of the items, I'd like to show this item on the map. The main complication lies in the fact that google maps uses javascript to control it and the listbox is a server control.

I can think of two ways to do this. The first would involve the listbox calling a javascript function when the user selects a new item. I can then write this function to perform the necessary map operations. Unfortunately, the OnSelectedIndexChanged property of the listbox doesn't seem to support javascript functions.

The second involves wrapping an UpdatePanel around the listbox and getting the listbox to perform a postback. In the SelectedIndexChanged event in VB/C#, I would the need to somehow make a call to a javascript function which would then update the map.

C# - Changing The SelectedIndex Of Multiple Select Listbox To The Last Selected Item?

Jan 18, 2011

Referring to a C#, .net, System.Web.UI.WebControls.Lisbox which has a multiple select option true and needs to do a postback every time selected index changes.

Problem is, the [SelectedIndex / SelectedItem / SelectedValue] is always on the value of the 1st selected item. Clicking on the second item, third item, does not change the SelectedIndex, causing the listbox to reload and scroll to the highest selected item position.
