View 9 RepliesI have two databound listboxes. The first only shows items that have been assigned to my product. The second listbox shows all available items. What I want to do is select all of the items in listbox 2 that list box one contains.
For example:
ListBox1-
Item 1
Item 3
ListBox2-
Item 1 (Selected)
Item 2
Item 3 (Selected)
Code I have:
List<string> myList = new List<string>();
foreach(ListItem f in ListBoxSourceDetail.Items)
{
myList.Add(f.Value);
}
myList.ForEach(delegate(string n)
{
ListBoxSourceEdit.SelectedValue = n;
});
I have a list box control (Multiple Selection):
<asp:ListBox ID="mLbMoney" runat="server" Rows="15" AutoPostBack="True"
onselectedindexchanged="mLbMoney_SelectedIndexChanged"
SelectionMode="Multiple"></asp:ListBox>
I'm trying to use the ListBox html helper in a simple form.
verhuurPrijzenLst is a simple list that gets put into the ListBox, I think I need "MultiSelectList", but I cannot use it (MVC framework needed)?
I don't know exactly how to do that ( bin folder and @inherits ? )
So it's nice to have a helper at hand, but if you cannot use it properly without using the MVC framework, that is a pity.

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.

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?
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.
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.
