Ok, for a beginner, here is the direction:
You need to use gridview's RowDataBound method. This will be called for row databind to grid. In this method, find the value of total for that row and add to a global counter. Assign the current total to the balance field of that row. Global counter will keep track of sum till that row bind giving you balance sum as you need.

Try now. If needed, read about RowDataBound and see how it works.

Solution 1

hi,

Add the column balance and below code in RowDataBound Event of the GridView

C#

//if bound column
if(e.Row.RowType==DataControlRowType.DataRow)
{
    if(e.Row.RowIndex==0)
    {
        e.Row.Cells[7].Text=e.Row.Cells[6].Text;
    }
    else
    {
        e.Row.Cells[7].Text = Convert.ToInt32(GridView1.Rows[e.Row.RowIndex - 1].Cells[7].Text) + Convert.ToInt32( e.Row.Cells[6].Text);
    }

}

//if template column

Label lbl = e.Row.FindControl("lblBalance") as Label;
if(e.Row.RowType==DataControlRowType.DataRow)
{
    if(e.Row.RowIndex==0)
    {
        lbl.Text=e.Row.Cells[6].Text;
    }
    else
    {
        lbl= Convert.ToInt32(((Label)GridView1.Rows[e.Row.RowIndex - 1].FindControl("lblBalance")).Text) + Convert.ToInt32( e.Row.Cells[6].Text);
    }

}

hope it helps.

{
e.Row.Cells[7].Text = (Convert.ToInt32(GridView1.Rows[e.Row.RowIndex - 1].Cells[6].Text) + Convert.ToInt32(e.Row.Cells[6].Text)).ToString();

add the template column in the gridview source along with other columns. take care about the column indexes.

<asp:GridView id="GridView1" runat="server">
<columns> <asp:TemplateColumn HeaderText="Balance">
<itemtemplate>
<asp:Label id="lblBalance" runat="server" Text="" />

Type 'System.Web.UI.WebControls.GridView' does not have a public property named 'TemplateColumn'. error message is displayed at line
<asp:TemplateColumn HeaderText="Balance">
i write
<asp:GridView ID="GridView1" runat="server" Width="453px" >
<asp:TemplateColumn HeaderText="Balance">
<asp:Label id="lblBalance" runat="server" Text="" />

add the template column in the gridview source along with other columns. take care about the column indexes.

ASP.NET

<asp:gridview id="GridView1" runat="server">
   <columns>
       <asp:templatecolumn headertext="Balance">
             <itemtemplate>
                  <asp:label id="lblBalance" runat="server" text="" />
             </itemtemplate>
       </asp:templatecolumn>
   </columns>
</asp:gridview>
