how I can read the selected field from the listbox?I have MSAccess table attached to the app.I can get to the properties, but I don't know which property gets me the data of the specific field.In VB it would be "listbox1.Column(x)", where 'x' represents the column number in the listbox1.I am using Microsoft Visual Web Developer 2010 Express
View 2 RepliesI must be doing something wrong, but this makes sense to me. I have a Listbox loaded with tons of items from a datasource. A user clicks one of these items it grabs the selectedindex (an integer) and stores it in a HiddenField (works fine).
Now when the page does a complete a refresh (after postback) I want the ListBox to go back to that selectedindex that is in the HiddenField. Problem is, it seems that after postback the HiddenField is empty? Then I thought about storing the value in an Integer variable in code, but that is simply coming up as a zero at all times.
Question 1: What is the best/simplest way to do this?
Question 2: How?
I am currently grabbing it on selectedindex change

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

Sub UpdateSwap(ByVal valueA As String, ByVal ValueBAs String, ByVal ValueC As Integer, ByVal ValueD As Date)
How to get the selected item from the listbox in the selected index changed event. I tried: Label1.Text = ListBox1.SelectedItem.Text; It is giving me object set to null reference.
foreach (ListItem item in ListBox1.Items)
{
if (item.Selected)
{
//lblResults.Text += item.Text + "
";
Label1.Text = item.Text;
}
}
No use, no value coming in to label.

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

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'm having trouble getting selected items in a listbox to be seen as selected. On my aspx page there's a listbox and a button:
[Code]....
But if I change my condition to Not selected, the string does build, with every item in the list. So the Sub is reached, the items and their text and values are seen, but user selection of items doesn't work. What am I missing?
When adding list item the Value field is being set to the Text field. Initially I though the problem was related to the input parameter for the primary key ( group_type_id ) as it is configured as OUTPUT variable.
Interesting enough, when I Watch all of the values, everything is correct.
So for example, I'll watch these:
ddr["group_type_name"] comes out as "Dept"
ddr["grouptypeid"] comes out as 4
When the item is created however,
itms.TEXT = "Dept"
itms.Value = "Dept" <-- THIS IS THE PROBLEM
I'm at a loss why the listbox values are being set to the text values when I can clearly see the data reader values are correct. ?
Code sample here:
[Code]....
I've got a list box that's populated by the user, I want to enter the selected items into an array, however I need both the indexes they have in the listbox as a whole, as well as their values.
For example, let's say that there is a listbox with 3 values and the user has selected just the first 2.
I would like to do a "for each" statement on only the selected items, so I would need their listbox indexes, the selected items indexes and their textual values.
I've tried multiple paths but all seem to just give me the textual representation of the selected item, but getting the correct indexes seems to be a problem for me.
