Solution 1

I am not sure if this is the right answer, tho you can use two controls to achieve what you want.
 
Use a Repeater which gets the unique days and then put the GridView inside that repeater.
 
Use the footer of the GridView to show the Sum of Income column.
 

<asp:Repeater> <!-- Get unique days -->
 <ItemTemplate>
  <asp:GridView> <!-- Bind the data based on the day -->
 </ItemTemplate>
</asp:Repeater>

Solution 2

put a textbox in the footer control then find the textbox control using
 
textbox txtSum= gridview1.FooterRow.FindControl("txtTotal") as TextBox
 
Then bind the total value to txtSum like how you will bind data to grid
 
txtSum= "select sum(income) from incometable"
