Show Selected Item In Listbox (System.Web.UI.WebControls)?

Feb 3, 2010

I'm working with a listbox that has, let's say, 20 items. The size of the listbox allows the user to see the first 5 items. However, the listbox has one preselected item which is sometimes not visible because it isn't one of the first 5 items.

After I set the selected Item for the listbox how can I ensure that the lisbox is scrolled appropriately so that the selected item is visible to the user?

.net - Listbox Selected Item Checking?

Aug 10, 2009

My code follows. I have six items (indices 0-6) and I'm trying to check if one has been selected or not. If not, then messagebox yells at you to select one. If it does, it tells you what you have selected. I'm having a horrible brain fart and contemplated coming here for about 45 minutes as I couldn't get it.

If ListBox1.SelectedItem.ToString <> "" Then
MessageBox.Show("You selected " + ListBox1.SelectedItem.ToString)
Else
MessageBox.Show("Please select an item.")
End If

C# - Get The Last Selected Item In Multiselect ListBox?

Apr 15, 2009

In .NET there doesn't seem to be a property to find the item just selected in a multi-select listbox; SelectedIndex always shows the first selected item. From memory VB6 had the ListIndex property that changed accordingly... Why remove a useful property ?

Edit Selected Item In Listbox?

Nov 8, 2007

So, I need to be able to edit an item that has been selected in a listbox. I need to do so with a button click event. Theoretically, I know how to do this, because I know how to add an item, and how to remove one, and how to insert an item at a specific location.

'Dim strinput As String
'Dim Item As Object
'Dim index As Integer = lstList.Items.IndexOf(item)
'strinput = InputBox("Edit This Item")
'lstList.Items.RemoveAt(lstList.SelectedItem)
'lstList.Items.Insert(index, strinput)

however, this does not work at all. what am I doing wrong??

How To Get The ID Number Of A Selected Item In Listbox

Dec 13, 2011

I am trying to use a listbox to hold categories from one table in a database and by clicking on the categories in the listbox it will display data from another table in the database that is linked to those categories. One table has a field called ID and the other has categoryID and categoryID is linked to ID so it displays the numbers from ID.I am using this:

daSamples.SelectCommand.CommandText = "SELECT * FROM tblSamples WHERE tblSamples.categoryid =" & (lstCategory.SelectedIndex + 1)
daSamples.Fill(dsSamples, "tblSamples")

Currently, however with this if you delete a category from the table with ID in it then it changes the values of the selectedindex in the listbox which messes up the data that gets displayed. How can i change this so instead of using the selectedindex from the listbox, it takes the ID from the selectedindex?
