Convert ListBox selectedvalue into INT

Question

Hi! I have a ListBox and I can get the selectedvalue. This selectedvalue is an int ID from an Access table. I have also checked the datatype by: textBox2.Text=ltbxLeft.SelectedValue.GetType().ToString(); It shows: System.Int32 . My problem is that I cann't convert this ltbxLeft.SelectedValue into an integer. such as: int id=int.Parse(ltbxLeft.SelectedValue.ToString()); I got en error message saying: System.FormatException: Input string was not in a correct format. Please help.

Hi You have to use SelectedItem. And them maybe its better to cast it. int id = (int) lb.SelectedItem; See msdn: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfsystemwindowsformscomboboxmemberstopic.asp Simon

How big are the values in the ListBox ? How is the listbox getting populated (DataSet Array by hand) ? Geo http://www.ezdevcomponents.com
