my aspx page code

<asp:GridView ID="gvStaff" runat="server" EmptyDataText ="No Record found" CssClass="table table-striped table-hover" BorderStyle="None" GridLines="Vertical" AutoGenerateColumns="false">
                                    <Columns>
              <asp:TemplateField HeaderText="Name">
                   <ItemTemplate>
                       <asp:Label ID="lblStName" runat="server" Text='<%#Eval("Name") %>'></asp:Label>
                   </ItemTemplate>
               </asp:TemplateField>
               </Columns>
                 </asp:GridView>

code Behind

Private Sub bindinboxgridview()
        Dim amonth As Integer = CInt(ddlMonth.SelectedValue.ToString)
        Dim ayear As Integer = CInt(ddlYear.SelectedItem.Text.ToString)

        Dim constring As String = ConfigurationManager.ConnectionStrings("EIMSConnectionString").ConnectionString
        Dim con As SqlConnection = New SqlConnection(constring)
        Try
            con.Open()
            Dim sqlComm As SqlCommand = New SqlCommand("sp_show_staff_att", con)
            sqlComm.Parameters.AddWithValue("@attmonth", amonth)
            sqlComm.Parameters.AddWithValue("@attyear", ayear)
            sqlComm.Parameters.AddWithValue("@result", SqlDbType.Int)
            sqlComm.CommandType = CommandType.StoredProcedure
            Dim ds As DataSet = New DataSet("TimeRanges")
            Dim da As SqlDataAdapter = New SqlDataAdapter
            da.SelectCommand = sqlComm
            da.Fill(ds)
            con.Close()
            If ds.Tables(0).Rows.Count > 0 Then
                gvStaff.DataSource = ds.Tables(0)
                gvStaff.DataBind()
            Else
                lblerror.ForeColor = Drawing.Color.Red
                lblerror.Text = "Record Not Found"
            End If

        Catch ex As Exception
            lblerror.ForeColor = Drawing.Color.Red
            lblerror.Text = ex.Message.ToString
        Finally
            con.Close()
        End Try
    End Sub

my stored procedure is

ALTER proc [dbo].[sp_show_staff_att](@attmonth int ,@attyear int,@result int output)
as

BEGIN
SELECT *
INTO #Temp
FROM 
  (SELECT [Emp_Code] ,[Name],[Status],attDay 
  FROM Table_Attendance_Staff WHERE attMonth =@attmonth  and attYear=@attyear ) as x        
    
DECLARE @DynamicPivotQuery AS NVARCHAR(MAX),@ColumnName AS NVARCHAR(MAX)
SELECT @ColumnName = ISNULL(@ColumnName + ',','')+ QUOTENAME(attDay) FROM (SELECT DISTINCT attDay 
FROM #Temp) AS [Days]
SET @DynamicPivotQuery = ';WITH CTE AS(SELECT [attDay],name,Status FROM #Temp )
SELECT name,'+@ColumnName+' FROM CTE
PIVOT (MAX(Status) FOR [attDay] IN('+@ColumnName+')) p 
ORDER BY name DESC'
EXEC(@DynamicPivotQuery)
drop table #Temp    
END

my table as

CREATE TABLE [dbo].[Table_Attendance_Staff](
	[Emp_Code] [varchar](30) NOT NULL,
	[Name] [varchar](60) NOT NULL,
	[Status] [char](1) NULL,
	[AttendanceDate] [varchar](50) NOT NULL,
	[attDay] [int] NULL,
	[attMonth] [int] NULL,
	[attYear] [int] NULL
