How To Get Column Other Total And Grand Total In Gridview

Jul 13, 2020 06:40 AM|Gopi.MCA|LINK

Hello

This Is My Aspx page

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false" OnRowCreated="OnRowCreated">
                <Columns>
                    <asp:BoundField DataField="Card_No" HeaderText="Card No" />
                    <asp:BoundField DataField="Day" HeaderText="Day" />
                    <asp:BoundField DataField="Dates" HeaderText="Dates" />
                    <asp:BoundField DataField="ItemName" HeaderText="ItemName" />
                    <asp:BoundField DataField="Qty" HeaderText="Qty" />
                    <asp:BoundField DataField="Value" HeaderText="Value" />
                </Columns>
            </asp:GridView>

This is my code behind

    {
        int flag = 0;
        for (int i = 0; i < dt.Rows.Count; i++)
        {
            string No = dt.Rows[i][0].ToString();
            if (No == celltext)
            {
                flag += 1;
            }
        }
        if (flag > 1)
        {
            return true;
        }
        else
        {
            return false;
        }
    }
}

This is the output its coming for now

I want Other Total and Final Grand Total Like This below

Thanking You

Hi Gopi.MCA,

I would not change your original codes too much. Instead, I add some methods to your codes so that it would be much easier to integrate my codes.

However, you might still need to refactor your codes after integration.

For the total rows implementation, you could refer to below codes. The additions are marked in yellow background:

ASPX:

<form id="form1" runat="server">
        <div>
            <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false" OnRowCreated="OnRowCreated" 
                OnRowDataBound="GridView1_RowDataBound" ShowFooter="true">
                <Columns>
                    <asp:BoundField DataField="Card_No" HeaderText="Card No" />
                    <asp:BoundField DataField="Day" HeaderText="Day" />
                    <asp:BoundField DataField="Dates" HeaderText="Dates" />
                    <asp:BoundField DataField="ItemName" HeaderText="ItemName" />
                    <asp:BoundField DataField="Qty" HeaderText="Qty" />
                    <asp:BoundField DataField="Value" HeaderText="Value" />
                </Columns>
            </asp:GridView>
        </div>
    </form>

Code behind:

protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                BindData();
            }
        }

        private void BindData()
        {

            string sql = "select [Card_No],[Day],replace(CONVERT(varchar(50),Dates,106),' ','-') as Dates,ItemName,Qty,Value from AAAAAA order by [Card_No] ";

            SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString);
            con.Open();
            SqlDataAdapter ad = new SqlDataAdapter(sql, con);
            DataTable dt = new DataTable();
            ad.Fill(dt);
            int rcount = dt.Rows.Count;

            
            for (int i = 0; i < rcount; i++)
            {
                if (!checkdtRepeat(dt.Rows[i][0].ToString(), dt))
                {
                    DataRow newRow = dt.NewRow();
                    newRow.ItemArray = dt.Rows[i].ItemArray;
                    dt.Rows.Remove(dt.Rows[i]);
                    dt.Rows.InsertAt(newRow, dt.Rows.Count + 1);

                //Calculate grand total before make any change
                grandTotalQyt += Convert.ToInt32(dt.Rows[i]["Qty"]);
                grandTotalValue += Convert.ToInt32(dt.Rows[i]["Value"]);
            }

            //Add Grand Total
            GridView1.FooterRow.Cells[3].Text = "<strong style='color: blue'>Grand Total</strong>";
            GridView1.FooterRow.Cells[4].Text = "<strong style = 'color: blue' >"+ grandTotalQyt.ToString() + "</strong>";
            GridView1.FooterRow.Cells[5].Text = "<strong style = 'color: blue' >" + grandTotalValue.ToString() + "</strong>";


        }

Demo:

BTW, I would not do the font-color stuff in codes directly (here is just for displaying the result). Therefore, just ignore the "<style>" in the codes if you mind.

Hope this can help you.

Best regards,

Sean

Re: How To Get Column Other Total And Grand Total In Gridview

Hi Gopi,

I know you have almost completed the implementation on the same. However, I see that there is HTML dependency on C# code. If you want, you can completely achieve the same with JavaScript. Here is a codebase with jQuery and underscore-

    public class Data
    {
        public string Card_No { get; set; }
        public string Day { get; set; }
        public DateTime Dates { get; set; }
        public string ItemName { get; set; }
        public int Qty { get; set; }
        public int Value { get; set; }
    }
    public partial class _2168936_How_To_Get_Column_Other_Total_And_Grand_Total_In_Gridview : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            var data = new List<Data>()
            {
                new Data(){ Card_No="A1", Day="D1", Dates=DateTime.Now, ItemName="Item 1", Qty=2, Value=29 },
                new Data(){ Card_No="A1", Day="D2", Dates=DateTime.Now, ItemName="Item 2", Qty=6, Value=9 },
                new Data(){ Card_No="M1", Day="D1", Dates=DateTime.Now, ItemName="Item 4", Qty=2, Value=39 },
                new Data(){ Card_No="M1", Day="D2", Dates=DateTime.Now, ItemName="Item 4", Qty=4, Value=19 },
                new Data(){ Card_No="M1", Day="D3", Dates=DateTime.Now, ItemName="Item 3", Qty=3, Value=59 },
                new Data(){ Card_No="B1", Day="D1", Dates=DateTime.Now, ItemName="Item", Qty=2, Value=29 },
                new Data(){ Card_No="C1", Day="D1", Dates=DateTime.Now, ItemName="Item 5", Qty=2, Value=39 },
