Ok, so your smple data has 3 months. (of course they are all the same - no doubt just for this example and testing).

So, drop a gridview on your page.

So, we have this:

And then in code behind, we can add a group by "month" to allow totals and a row for each month.

So, this code:

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load  
  
        If Not IsPostBack Then  
            LoadGrid()  
        End If  
  
    End Sub  
  
  
    Sub LoadGrid()  
  
        Dim strSQL As String =  
            "SELECT month(date) As MyMonth, sum (Opening) as Opening,  sum (Purchase) as Purchase,  
            sum (Stk_Tfr_In) as Stk_Tfr_In,sum (Stk_Tfr_Out) as Stk_tfr_Out,  
            sum (Damaged) as Damaged,sum (StoreOut) as StoreOut,sum (Closing_Stk) as Closing_Stk  
            FROM data1  
            WHERE MONTH(DATE) in (9,10,11)  
            group by month(date)"  
  
        Using conn As New SqlConnection(My.Settings.TEST4)  
            Using cmdSQL As New SqlCommand(strSQL, conn)  
                conn.Open()  
                GridView1.DataSource = cmdSQL.ExecuteReader()  
                GridView1.DataBind()  
            End Using  
        End Using

And now the results are this:

so you can add a group-by month, and it will split out the totals for each month.

if you want a sum (footer), then to gv, add ShowFooter="true"

and then this:

        Using conn As New SqlConnection(My.Settings.TEST4)  
            Using cmdSQL As New SqlCommand(strSQL, conn)  
                conn.Open()  
                rstData.Load(cmdSQL.ExecuteReader)  
                GridView1.DataSource = rstData  
                GridView1.DataBind()  
            End Using  
        End Using  
  
        Dim gF = GridView1.FooterRow  
        gF.Cells(0).Text = "Totals"  
        For i = 1 To rstData.Columns.Count - 1  
            gF.Cells(i).Text = rstData.Compute("SUM(" & rstData.Columns(i).ColumnName & ")", "")  
        Next

And if you want all cells right justifed, then add a item row bound like this:

    Protected Sub GridView1_RowDataBound(sender As Object, e As GridViewRowEventArgs) Handles GridView1.RowDataBound  
  
        If e.Row.RowType = DataControlRowType.DataRow Or  
            e.Row.RowType = DataControlRowType.Footer Then  
  
            For i = 1 To rstData.Columns.Count - 1  
                e.Row.Cells(i).HorizontalAlign = HorizontalAlign.Right  
            Next  
  
        End If  
  
    End Sub

And now you have this:

Hi @Baiju EP ,
I wrote example according to your needs.
First, you can use the DATEPART function to specify the date part, then group the year and month, and then use the CONCAT function to combine the year and month to display the month and year at the same time.
The Total section can be displayed through the GridView footer.
For details, you can check the code below.

<div>  
            <asp:GridView ID="GridView1" runat="server" ShowFooter="true"></asp:GridView>  
        </div>

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load  
        If Not Me.IsPostBack Then  
            Dim con As SqlConnection = New SqlConnection(ConfigurationManager.ConnectionStrings("DBCS").ConnectionString)

 Dim adp As SqlDataAdapter = New SqlDataAdapter(SelectQuery, con)  
        Dim dt As DataTable = New DataTable()  
        adp.Fill(dt)  
        GridView1.DataSource = dt  
        GridView1.DataBind()  
        Dim totOpening As Decimal = dt.AsEnumerable().Sum(Function(row) row.Field(Of Decimal)("Opening"))  
        Dim totPurchase As Decimal = dt.AsEnumerable().Sum(Function(row) row.Field(Of Decimal)("Purchase"))  
        Dim totStk_Tfr_In As Decimal = dt.AsEnumerable().Sum(Function(row) row.Field(Of Decimal)("Stk_Tfr_In"))  
        Dim totStk_Tfr_Out As Decimal = dt.AsEnumerable().Sum(Function(row) row.Field(Of Decimal)("Stk_Tfr_Out"))  
        Dim totDamaged As Decimal = dt.AsEnumerable().Sum(Function(row) row.Field(Of Decimal)("Damaged"))  
        Dim totStoreOut As Decimal = dt.AsEnumerable().Sum(Function(row) row.Field(Of Decimal)("StoreOut"))  
        Dim totClosing_Stk As Decimal = dt.AsEnumerable().Sum(Function(row) row.Field(Of Decimal)("Closing_Stk"))  
        GridView1.FooterRow.Cells(0).Text = "Total"  
        GridView1.FooterRow.Cells(0).HorizontalAlign = HorizontalAlign.Right  
        GridView1.FooterRow.Cells(1).Text = totOpening.ToString()  
        GridView1.FooterRow.Cells(2).Text = totPurchase.ToString()  
        GridView1.FooterRow.Cells(3).Text = totStk_Tfr_In.ToString()  
        GridView1.FooterRow.Cells(4).Text = totStk_Tfr_Out.ToString()  
        GridView1.FooterRow.Cells(5).Text = totDamaged.ToString()  
        GridView1.FooterRow.Cells(6).Text = totStoreOut.ToString()  
        GridView1.FooterRow.Cells(7).Text = totClosing_Stk.ToString()  
        con.Close()  
        adp.Dispose()  
        dt.Dispose()  
    End If      
End Sub
