{       if (listbxSelComp.Items[i].Selected==true)

                           listbxSelComp.Items.Remove(listbxSelComp.Items[i]);

instead of using index property use

foreach (ListItem lItem in listbxSelComp.Items)
{
if (lItem.selected == true)
  listbxSelComp.Items.Remove(lItem)
}

Regards,

Thanks for your reply sir. i have changed in my exisging code but i got error with the following :

error: collection was modified; enumeration operation may not execute.

at line:  foreach (ListItem lItem in listbxSelComp.Items)

could you help me in this regards plz thks

then you have to looping backward.

Dim mIndex As Integer
For mIndex = listbxSelComp.Items.Count - 1 to 0 ' Looping Backwards
If listbxSelComp.Items(mIndex ).Selected Then
listbxSelComp.Items.Remove(listbxSelComp.Items(mIndex )
End If
Next

 I am sure it will work.

Regards,

Try to get the selected items in collections then sort the collection and then remove list items using negative index.

Hope the following sample code helps.

Hi Dk,

Please try the following code

    {
        ArrayList values=new ArrayList ();
        foreach (ListItem li in ListBox1.Items)
        {
            if (!li.Selected)
                values.Add(li.Text);
        }
        ListBox1.DataSource = values;
