If you are using DataSet or DataTable to bind your grid dynamically use one of the following versions of the code in the RowDataBound event of GridView assuming you have a lable named lblTotalRecords and lblTotalDisplayedRecords.
'Page Level variable defined

Private m_intTotalRecords As Integer
 

'During data binding store total number of records in a page-level variable

m_intTotalRecords = DataSet1.Tables(0).Rows.Count
 

'OR
 

m_intTotalRecords = DataTable1.Rows.Count
 
 

'Write the following in RowDataBound event of GridView
 

If e.Row.RowType = DataControlRowType.Footer Then
 

  'Number of total records

  CType(e.Row.Cells(0).FindControl("lblTotalRecords"), Label).Text = m_intTotalRecords.ToString()

  'Number of records displayed

  CType(e.Row.Cells(0).FindControl("lblTotalDisplayedRecords"), Label).Text = GridView1.Rows.Count
 

End If

See the code below:
//Page Level variable defined

private int m_intTotalRecords;
 

//During data binding store total number of records in a page-level variable

m_intTotalRecords = DataSet1.Tables(0).Rows.Count;
 

//OR
 

m_intTotalRecords = DataTable1.Rows.Count;

    

    

//Write the following in RowDataBound event of GridView
 

if (e.Row.RowType == DataControlRowType.Footer) {

  

  //Number of total records

  ((Label)e.Row.Cells(0).FindControl("lblTotalRecords")).Text = m_intTotalRecords.ToString();

  //Number of records displayed

  ((Label)e.Row.Cells(0).FindControl("lblTotalDisplayedRecords")).Text = GridView1.Rows.Count;

}

If you atleast know the number of columns being created dynamically, you may acheive this in GridView_PreRender event. Using a loop traverse through the rows and for each coloumn note the value (to be summed) in a separate variable (one for each column).  Have a check in the loop to check if the RowType is DataRow and if the RowType is Footer then write out these values. Try using the following code in GridView_PreRender.

int intColumn1 = 0;

int intColumn2 = 0;
 

foreach (GridViewRow row in GridView1.Rows)

{

  if (row.RowType == DataControlRowType.DataRow)

  {

      intColumn1 += (int)row.Cells(0).Text;

      intColumn2 += (int)row.Cells(1).Text;

  }

  

  if (row.RowType == DataControlRowType.Footer)

  {

      ((Label)row.Cells(0).FindControl("lblTotalColumn1")).Text = intColumn1.ToString();

      ((Label)row.Cells(2).FindControl("lblTotalColumn2")).Text = intColumn2.ToString();

  }

}

The attached image is totally black. Please save it as JPEG instead of BMP in paint or whatever tool you used to take snapshot and re-attach.
For your problem in footer, make sure you have set ShowFooter property of the GridView to True. Further, replace line 14 and 15 of the above code with the code below, however make sure you are passing right index value in Cells():

row.Cells(0).Text = intColumn1.ToString();

row.Cells(1).Text = intColumn2.ToString();

Please use the following as guided and for more details on a similar solution see the following link:
http://www.asp.net/Learn/data-access/tutorial-15-vb.aspx

//use these lines outside the loop and remove if statemetn for rowtype = footer

GridView1.FooterRow.Cells(0).Text = m_intColumn1.ToString();

GridView1.FooterRow.Cells(1).Text = m_intColumn2.ToString();
 

//another alternative would be this solution

//create these variable at page level

int m_intColumn1 = 0;

int m_intColumn2 = 0;
 

//use this code in RowDataBound event rather than PreRender event

if (e.Row.RowType == DataControlRowType.DataRow)

{

    intColumn1 += (int)e.Row.Cells(0).Text;

    intColumn2 += (int)e.Row.Cells(1).Text;

}
 

if (e.Row.RowType == DataControlRowType.Footer)

{

    e.Row.Cells(0).Text = m_intColumn1.ToString();

    e.Row.Cells(1).Text = m_intColumn2.ToString();

}
