Gridview total

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

I m using asp.net with c#...

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;
}

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 code I posted in my last comment.

yes i have use that code but that code will  display total in last row of the grid only when i comment the
if (row.RowType == DataControlRowType.Footer)
            {
}
loop...instead of footer of the grid....when i remove the comment from if loop the it will show the error...

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();
}
