how to display pagetotal and grand total in gridview Footer Template in asp.net


                  



Description:-                


In this example we explain that how to Display PageTotal and GranTotal in your GridView.
Listen this thing you have a Qustion in Your Mind is that what is PageTotal and What is GrandTotal.so now we explain that suppose your Gridview Contain 10 pageview with 20 rows in each pageview so finally your Gridview can contain 200 rows.

So Pagetotal means  total of each pageview so in this case total of 20 Record because our Gridview contain 20 Record in each pageview.

And now the GrandTotal means the Total of All pageview so in this case total of 200 Record because our Griview can contain 10 Pageview with 20 record in each pageview so 20*10=200.

We also provide Facility for Edit and Delete Record and main Important point is that the calculation of PageTotal and GrandTotal are Automatically change as per record Deleted.
To do this we Create all Calculation in RowdataBound Event of the GridView are as Follow

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

        {

            Label rn = (Label)e.Row.FindControl("lblrn");

            Label gr = (Label)e.Row.FindControl("lblgrand");

            rn.Text = irn.ToString();

            gr.Text = to();

        }
 
Look at this It will Check that this RowType is Footer then it will Find Label in Footer in each row and assign Total to this Label. Here to is the Function that will Return the Total of all row in Gridview.

public string to()

    {

        string con = @"Data Source=SQLDB;Initial Catalog=Demo;User ID=Demod;Password=Demo1@";

        String q2 = "select sum(total) from manage";

        SqlConnection cn = new SqlConnection(con);

        SqlCommand cmd1 = new SqlCommand(q2, cn);

        cn.Open();

        string total = cmd1.ExecuteScalar().ToString();

        return total;

    }

So this type of Facility are very useful  In Billing System to Generate a Bill Report.
