what difference between gridview and data bound

Hi Fire,

We use gridview databound event when we want to do certain things after the server controls bind to the datasource. For example after the binding we may want to display some text at the bottom of the grid or we might want to calculate the total value of a column.

Here is the example of how to use gridview databound event.

THIS IS AN ASPX FILE:

<h1>GridView Demoh1>

<asp:GridView ID="GridDataBound" runat="server" AutoGenerateColumns="False"

<asp:BoundField DataField="Age" HeaderText="Age" SortExpression="Age" />

<asp:BoundField DataField="MarksInMaths" HeaderText="MarksInMaths"

SortExpression="MarksInMaths" />

<asp:BoundField DataField="MarksInEnglish" HeaderText="MarksInEnglish"

SortExpression="MarksInEnglish" />

<asp:BoundField DataField="MarksInScience" HeaderText="MarksInScience"

SortExpression="MarksInScience" />

<asp:BoundField DataField="TotalMarks" HeaderText="TotalMarks"

SortExpression="TotalMarks" />

<asp:BoundField DataField="ObtainedMarks" HeaderText="ObtainedMarks"

SortExpression="ObtainedMarks" />

    }

        GridDataBound.ShowFooter = true;
 
        //Remove un-use  GridDataBound
        for (int i = GridDataBound.Columns.Count - 1; i > 0; i--)
        {
            GridDataBound.FooterRow.Cells.RemoveAt(i);
        }
 
        GridDataBound.FooterRow.Cells[0].ColumnSpan = GridDataBound.Columns.Count;
        GridDataBound.FooterRow.Cells[0].HorizontalAlign = HorizontalAlign.Center;
 
        GridDataBound.FooterRow.Cells[0].Text = "This is an example of data bound event";
    }   
}
