You forgot the lvHoliday_ItemInserting in the code behind.  Make sure the case is correct.

Please take a moment to review your code...

Hi JagjitSingh,

According to your description, I guess there are something wrong with your lvHoliday_ItemInserting event.

For example, you missed the method's parameter in the lvHoliday_ItemInserting event.

Like below:

        protected void ListCategories_ItemInserting( )
        {

        }

It will show below error:

The right lvHoliday_ItemInserting method:

        protected void ListCategories_ItemInserting(object sender, ListViewInsertEventArgs e)
        {

        }

Best Regards,

Brando
