Edit The listbox selected text in Runtime asp.net

I have a listbox in asp.net I tried when user click on it's item in runtime can change the text of this item without change the order of the the items . So I try to make Edit button when click on it get the item value as

 protected void btnEditListValue_Click(object sender, EventArgs e)
        {
            string listvalue = lstParameters.Items.IndexOf(lstParameters.SelectedItem).ToString();
            string listText = lstParameters.SelectedItem.ToString();
        }

then I will make textbox fill value from string listText to enable user to edit

what shall I do after that to keep listbox order as old without delete and insert again

please help

You can overwrite the ListItem.Text, f.e. when the user changed the text:

protected void TextBox1_TextChanged(object sender, EventArgs e)
{
   if(lstParameters.SelectedIndex >= 0 && !String.IsNullOrWhiteSpace(TextBox1.Text))
   {
       ListItem selectedItem = lstParameters.Items[lstParameters.SelectedIndex];
       selectedItem.Text = TextBox1.Text;
   }
}
