exclude dinamic value from listbox

[Mirnes]

I have a listbox which is populated from Sql query and I use it to add
values to table. I would like to exclude value which just has been
added from listbox. Since it is impossible to do in query which is
datasource for query is there some other option.

Hi Mirnes,

You have to handle DataBound of the ListBox event and remove whatever you
don't need:

protected void ListBox1_DataBound(object sender, EventArgs e)
{
ListBox listBox = (ListBox)sender;
// there are two methods you can use
//ListItem listItem = listBox.Items.FindByText("ItemText");
// or
ListItem listItem = listBox.Items.FindByValue("3");
if (listItem != null)
{
listBox.Items.Remove(listItem);
}
}


hope this helps
