Im Using asp .net with Vb Coding.
I have to remove the list of selected items from listbox .
Dim i As Integer
For i = 0 To listbox1.Items.Count - 1
listbox1.Items.Remove(listbox1.SelectedValue.ToString())
Next
My doubt is If i run the page again the listbox shows the items which i deleted already.
txtquantity.text = lborderlist.Items.Count.ToString(); -> this codes adds how many you have input in the listbox, now i need to know the opposite..
how to remove items from a listbox but it should also counts the how many you have left in the listbox..
I'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.
I have 2 ListBoxes. 1st SelectionMode is Multiple. Once I select many options from 1st ListBox I can copy it in ListBox2 but i Unable to remove it.
Code :
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
For i = 0 To ListBox1.SelectedItems.Count - 1
ListBox2.Items.Add(ListBox1.SelectedItems(i).ToString())
' ListBox1.Items.Remove(ListBox1.SelectedItems(i).ToString()) it is not removing.
Next
End Sub
I have a List in which I select users from db each time a sql query runs with certain value and selects one user in the time thus I cannot limit identical users in sql.
I have list with:
list[0] = "jerry"
list[1] = "tom"
list[2] = "jerry"
I want any (first or last doesn't matter in my case) to be removed from the list.
For my site, I have a list of users and a list of events. I will be assigning users to each event. I have a table named EventUsers to hold this data:
EventUsers
EventID | UserID
1 | 123
1 | 456
2 | 789
On my page, I want to be able to add and remove users for a certain event. I could have a dropdown populated with users and an "Add" button next to it, then when I want to add a user, I pick one and click "Add". There would be a grid below it displaying all the users for the event, with "Delete" buttons for each one. The downside to this is that a database call is made for every Add and Delete.
Another option is to have two listboxes on the page - one on the left containing all users in the database, and another on the right which will contain users for the given event, and I can just add or remove from the list on the right. Then when I'm done, I click save, and it makes one database call. The only issue is that if I'm removing and adding, I'll have to delete every record in my EventUsers table for that event, and then add the changes. I've run into this before, and I've always gone with the dropdown method. What's the preferred method here?
I have a drop down that lists all our 40+ locations.. I then have a list box with all our locations as well. The client is presented with the question which locations have you worked at before. If they pick say 3 locations, i need to remove or disable those 3 from the drop down. I have other code for creating a drop down, but not sure where to go with this.
Here is my code for the controls and code behind:

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

This has got to be more simple than I'm making it. I want to generate a listbox with years for the values. It needs to be dynamic. It needs to list from 17 years ago to 25 years ago. This is what I have so far, I get the correct number of items in the listbox, but I don't get the correct value. They are all "1985".
<%
Dim y As Integer
Dim NextTime As Date = Now
Dim bday_yr As New ListItem()
y = 0
For y = 17 To 25
NextTime = DateAdd(DateInterval.Year, -y, System.DateTime.Now)
bday_yr.Value = NextTime.Year
bday_yr.Text = NextTime.Year
BirthYear.Items.Add(bday_yr)
Next
%>
<asp:DropDownList ID="BirthYear" runat="server">
</asp:DropDownList>
I am moving an app from Silverlight back to ASP.NET. (Don't ask!) I really liked the ability to highlight ListBox items as the user moved the mouse over the items. I have been Bing'ing all morning and cannot seem to find any way to do this in ASP.NET with an ASP:ListBox. I tried setting the onmouseover event for the list items themselves. But that did nothing.
[Code]....
I then tried setting onmouseover event for the list itself. I can get the event, but I don't know how to determine which item I am over. I only seem to have the selectedIndex. If I am just moving the mouse, I have no selectedIndex.
I am not able to give spaces between two items in list box. I tried with css- padding, but no luck.

View 2 RepliesI'm trying to populate 1000 ListItems in a ListBox.
how to do it. Currently only 100 items are being displayed even though I set the capacity of the ListBox to 1000.
Below is sort of how my code looks like. :)
listBox.Items.Capacity = 1000;
foreach(entity ent in enitityCollection)
{
ListItem listItem = new ListItem();
listItem.Value = ent.Id.ToString();
listItem.Text = ent.Name;
listBox.Items.Add(listItem);
}
entityCollection has 989 records in it.
Code does not generate any error. only that at the end of the loop I only get 100 items mapped to my ListBox.
Is this how the ListBox is designed for?
I have a list box which is populated using a dictioanry. When I iterate throught the selected items using the following code, it always show only the first items as selected - even if the first item is not selected. Have you ever encountered this scenario? This problem occurs when I use dictionary for binding. On the other hand a generic list works fine.
private void PopulateListBox2()
{
List<string> subjectList = new List<string>();
subjectList.Add("Maths");
subjectList.Add("Science");
ListBox1.DataSource = subjectList;
ListBox1.DataBind();
}
Even it will work fine, if the values are unique. But in my scenario, the values are same; only key varies. The following works
private void PopulateListBox5()
{
Dictionary<string, string> resultDictionary = new Dictionary<string, string>();
resultDictionary.Add("Maths", "Lijo1");
resultDictionary.Add("Science", "Lijo2");
ListBox1.DataValueField = "Value";
ListBox1.DataTextField = "Key";
ListBox1.DataSource = resultDictionary;
ListBox1.DataBind();
}
The following code has the problem......................
I've been trying to figure out for a long time now how to create an interface that can allows users to input several rows of data and pass those entries into an SQL server database all in one shot. I could not get any better ideas so I came up with this (see picture below).
What I envisioned is that the user enters values in the textboxes and hits the "add to list" button. The values are then populated in the list box below with the heading "exhibits lists" and when the add exhibit button is pressed, all values from the list box are passed into the database.
Well, I'm left wondering again if it would be possible to tie these values from the textboxes to the list box and whether I'd be able to pass them into the database.
how to go about it otherwise I'd be glad if you could recommend a better way for me to handle the situation otherwise I'd have to resolve to data entry one at a time.
Im adding items to listbox by using jquery but when i look to the page source(html source) ,the items that I've added dont seen.Im adding items by this way
