I 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'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 want my Start Time and End TIme should not be equal to each other and I want the End TIme should not go beyond the Start TIme. For example:
Start Time = 8:30 AM
End Time = 8:00 AM
The above example should have an error because the End Time go beyond the Start Time.

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've a list box which may contain 300000 or more records. I've another listbox . The user basically selects from the first listbox and adds to second lbx. There is button which when clicked will move the selected records from first listbox to second listbox.
Now if I select around 45000 records and try to move to second listbox .. it moves fine . If I select more than 45000 or so...it takes very long and eventually i get the "Action Cancelled". When I put a break point in page_init ..it does not hit. Is there a way I can restrict the user by selecting more than 40000 items. ie they should not be able to highlight more than 45000 records.
I have a dataTable that contains a specific column from a database. A listbox contains 100 list items in it. When page loads, I need those listbox items to be selected, whose value matches the value in the datacolumn of the datatable.
Following is the code i tried, but is not working. For some reason, it selects only the last item in the datacolumn.
if (datTableRelatedSchool.Rows.Count == 0)
{
}
else
{
foreach (DataRow row in datTableRelatedSchool.Rows)
{
foreach (DataColumn myCol in datTableRelatedSchool.Columns)
{
lstRelatedSchool.SelectedValue = row["RelatedSchoolPK"].ToString();
}
}
}
