CommandItemSetting section in RadGrid is not displayed when Grid has less than 10 records - export-to-excel

Question

I'm using CommandItemSettings in MasterTablreView to show Export to Excel button.
The CommandItemSettings section of the grid is displayed when Grid has at least 10 records or when I select less than 10 records using a Pager.
However, with less than 10 records after I click the Search button, the CommandItemSettings section is not there and I cannot export the data into an Excel.
Here is the aspx file:
