    [CLOSED] TabPanel tabs activating differently if remove tabs

    Hi,

    In my web application I need to add tabs to tab panel at bottom of the form and based on tab selection the required information related to selected tab will show in center panel. For demo purpose I have added one toolbar at top of the form as showing in the image. In left textfield enter number of tabs required, and click Open forms button. The number of tabs will add at bottom. Just click on each tab and see the tab related info will show in the center panel.
    Now add any tab number (without zeros) in right textfield in toolbar and click "Delete this number form", it will delete the entered number tab. Once delete any tab, I want to load ("ExtSampleForm.aspx"). It is working fine if we add extreme tab number and click "Delete this...", but it is not working correctly if we enter first tab number to delete. It is loading all tabs info form one by one and finally shows one tab info form, but I want to show only "ExtSampleForm.aspx" all the time when delete any tab.

    The main form code...
