Value does not fall within the expected range

Question

I am using the following code to update a listbox  this recieving a list from a Web service   client userKeywordsCompleted    new EventHandler lt userKeywordsCompletedEventArgs gt  client userKeywordsCompleted   client userKeywordsAsync      Using   void client userKeywordsCompleted object sender  userKeywordsCompletedEventArgs e         string result   System Convert ToString e Result        for  int i   0  i  lt  e Result Count  i                   ListBoxItem lbitem   new ListBoxItem             lbitem Name    lb     i          lbitem Content   e Result i            lbitem AddHandler UIElement MouseLeftButtonDownEvent  new MouseButtonEventHandler ListBoxItem DoubleClickEvent   true            listBox1 Items Add lbitem            This works fine  as I use it when the Child window loads  so the ListBox gets the list from the database  however  when a user selects one of the items in the ListBox  they have the option to edit the selected item  So once the edit is in place  there is an edit button  which updates the column in the table in the database  So then on the button click  I am again calling the aforementioned code to update the ListBox with the new credentials  However  this brings back the error -   Value does not fall within the expected range     Why can I not call the Web method on the button click  as all it is doing is refreshing the ListBox

This might be due to the fact that you are trying to add a ListBoxItem with a same name to the page.

If you want to refresh the content of the listbox with the newly retrieved values you will have to first manually remove the content of the listbox other wise your loop will try to create lb_1 again and add it to the same list.
