I have 2 listboxes....
Listbox1 has
DataTextField="Category"
DataValueField="CategoryID"
(coming from Dropdownlist)
I want to move a Item (a Category) from listbox1 to listbox2...but how do I move this Category Plus the CategoryID to lisbox2 (CategoryID should not be visible but still be associated with Category in Listbox2)
So I want the newly added Categories to be visible in Listbox2 ..but their CategoryID's must be invisible...but still be associated with their Category....
and when I save these Categories from Listbox2 to the Database.....its should be the CategoryID's that should go into the Database.....not the actual Category
So to explain again in a different way
I want to Move a selected DataTextField & its DataValueField from Listbox1 to listbox2
then only the array of DataValueField must be saved to Database
I have 2 ListBoxes..ie ListBox1 and ListBox2.When Move items from ListBox1 to ListBox2,I want to save listBox2 values in Xml Files.When i open the page it will load lListBox2 values.

Overview
I have 3 update panels on a page, each of them have UpdateMode="Conditional".
UpdatePanel1 contains listbox1 (AutoPostBack set to true) which is populated on pageinit from the DB.
UpdatePanel2 contains listbox2 (AutoPostBack set to true), this panel has AsyncPostBackTrigger set to the SelectedIndexChanged event for listbox1 in UpdatePanel1.
UpdatePanel3 contains textboxes that will hold the details once an item has been selected from listbox1 and listbox2, this panel has an AsyncPostBackTrigger set to the SelectedIndexChanged event for listbox2 in UpdatePanel2.
In the codebehind, the SelectedIndexChanged event for listbox1 populates listbox2 and the SelectedIndexChanged event for listbox2 populates the textboxes in UpdatePanel3.
The problem
When the page loads listbox1 is correctly populated, I select a value from listbox1 and listbox2 is populated, great, no problem so far. When I then select a value from listbox2 the SelectedIndexChanged event for listbox1 is firing, I assume that as this populates listbox2 again it is clearing the selected value for listbox2 as the SelectedIndexChanged event for listbox2 is not firing.
How do I stop the SelectedIndexChanged event for listbox1 in UpdatePanel1 from firing when I select a value from listbox2 in UpdatePanel2 ?
I have 4 Checkboxlists, if i check 1st item of checkboxlist1 -- > populate items in checkboxlist2 if i check 2nd item in checkboxlist1 -- >populate items in checkboxlist2 with last selection as well as 1st checkboxlist items. So I need to Append items in Checkboxlist with existing items and also with previously selected Checkox. Is it any way except DataTable ?

I have a few tables, Listings, ListingImages and a few others related to Listings. ListingImages is related to Listings so that you can have many ListingImages per Listing.
When I query this table I do;

Now this is fine. However, I now want to sort the ListingImages independently within each Listing (by an ImageOrder column I have in that table).
How can I do this and pass all my Includes(...). Would it be bad form to sort the ListingImages within the View as this solution seems to work?

It always displays ONLY 10 items although there are 30 items in the datatable. If i use GridView ALL the 30 items are displayed just fine.
So I have a ListView (assignmentsListView) in an UpdatePanel, being filtered by a DropDownList in the same UpdatePanel. The DropDownList has a list of persons in it and uses autopostback, and the ListView shows the tasks those persons are assigned to.
I am trying to use code similar to this:
[code]....
When I first load the page, the DropDownList shows the first person in the list, and the ListView correctly shows that persons tasks.
If I then select a person who I know has zero tasks, I get an error at the RegisterPostBackControl() method, saying the passed-in control cannot be null.
When debugging, at the RegisterPostBackControl method, it shows that the ListView Items collection has >0 elements in it (the number of elements matches the person selected before the current person).
I seem to be having problems trying to add an item to a dropdownlist that has a defined datasource:

but, the item never appears in the dropdownlist, regardless of how I try to modify the .add code....

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 8 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?
