Where do you get the items from? If you for an example get them from a database, it's easier and more efficient to remove duplicates and sort in the database query, than writing code for it.

Guffa,
I get the items from a db call to populate the left listbox on my page. The user will click on this listbox to transfer the "number" over to the right side listbox, Listbox2, on the page.
I'm trying this code to sort the items in Listbox2, but get:
At least one object must implement IComparable.
Dim items As New ArrayList(ListBox2.Items)
items.Sort()
ListBox2.DataSource = items
|
|
|
|
|
Implement an IComparer for ListItem, and use that in the call to the Sort method.
But, shouldn't you do this using client script instead? If you use server code to move the items, you will be sending a lot of data back and forth between the server and the client.

I’m new to ASP.NET and I have been having trouble developing some of the client-side script. I have two webforms that are in two frames in a window. The first webform has a datagrid and the second (main webform) has javascript that will updates it’s contents based on the selected value in the datagrid. I would like to execute specific script on the main webform when the user makes a selection in the datagrid. I would also need to send the datagrid’s selected value to the main webform. I can’t find any references about this process. Any input on this would be appreciated.

If your subject is the same as the qustion, either the subject is way too long, or the question is way to short.
In this case, obviously, it's the second. You have to explain a lot more about what you are trying to do.

If you're using themes, you could create a skin for the Label control with only a few properties set at design time. Then set the ones you want at runtime.

No, i am not using themes. I am creating a custom control please send me code if anybody have.
Thanks in advence

I have a page with lot of JavaScript on a page and a few DB functions\
Why is there a very long string (more than 150 lines) in the __VIEWSTATE variable?

u can manager ur viewstate on the server.
as a example u can store viewstate in table or session.
if u search codeproject having keyword viewstate then u can many article with code that how to optimize viewstate on the server side.pls search codeproject.

The __VIEWSTATE field contains the ViewState of the page. Some controls, like the DropDownList control, store all the data needed to recreate the control after postback in the ViewState.
You can disable this for each control using the EnableViewState property, or you can disable the ViewState for the entire page.

If you are using response.redirect then the page will be called from the server only.
