How to insert a new row between another rows in gridview boundfield? - asp.net

Question

I have a gridview like below picture:
In this gridview I want to introduce a new row that does not have any completely out of the cell where the last "Grand Total" there to put a variable mine.
But the question is, how introduce a new row among others?
My code is:
Dim Qty As Double = 0
Dim CostCategory As Double = 0
Dim AssemblyDate As String = Nothing
If GridView1.Rows.Count <> 0 Then
For x As Integer = 0 To GridView1.Rows.Count - 1
For y As Integer = 0 To GridView1.Columns.Count - 1
If y = 0 And GridView1.Rows(x).Cells(1).Text = AssemblyDate Then
GridView1.Rows(x).Cells(1).Text = ""
End If
If GridView1.Rows(x).Cells(1).Text <> Nothing Then
AssemblyDate = GridView1.Rows(x).Cells(1).Text
End If
If y = "9" Then
Qty = Convert.ToDouble(GridView1.Rows(x).Cells(9).Text)
End If
If y = "13" Then
CostCategory = Convert.ToDouble(GridView1.Rows(x).Cells(13).Text)
End If
If y = "14" Then
GridView1.Rows(x).Cells(14).Text = Qty * CostCategory
GridView1.Rows(x).Cells(14).HorizontalAlign = HorizontalAlign.Center
End If
If GridView1.Rows(x).Cells(y).Text = "Yes" Then
GridView1.Rows(x).Cells(y).BackColor = System.Drawing.Color.LawnGreen
ElseIf GridView1.Rows(x).Cells(y).Text = "No" Then
GridView1.Rows(x).Cells(y).BackColor = System.Drawing.Color.Red
End If
Next
Next
End if
before that code i have a query where i fill my gridview:
Dim myQuery As String = SelectQuery & WhereQuery
SqlDataSource1.SelectCommand = myQuery
SqlDataSource1.DataBind()
GridView1.DataSourceID = "SqlDataSource1"
GridView1.DataBind()
Thanks a lot!

Try using this
DataRow dr = tblTable.NewRow(); //Create New Row
dr["ColumnName"] = "Legs"; // Set Column Value
tblTable.Rows.InsertAt(dr, 11); // InsertAt specified position
For VB.Net Grid View
Dim rowNumber As Integer = dGrid.CurrentCell.RowNumber() + 1
Dim myNewRow As DataRow = myDataTable.NewRow()
myDataTable.Rows.InsertAt(myNewRow, rowNumber)
myDataTable.AcceptChanges()
