Create the event
    this.dtgSortAndPaging.ItemDataBound += new
    DataGridItemEventHandler(dtgSortAndPaging_ItemDataBound);


Create the function:

System.Web.UI.WebControls.DataGridItemEventArgs e)

Hi Javier,

Here's an example in VB.NET that might give you the idea.

  Private Sub Page_Load(ByVal sender As System.Object, _
    ByVal e As System.EventArgs) Handles MyBase.Load
        If Not IsPostBack Then
            DataGrid1.DataSource = CreateDataSource()
            DataGrid1.DataBind()
        End If
    End Sub

    Private Sub DataGrid1_ItemDataBound _
    (ByVal sender As Object, ByVal e As _
    System.Web.UI.WebControls.DataGridItemEventArgs) _
    Handles DataGrid1.ItemDataBound
        If e.Item.ItemType = ListItemType.AlternatingItem Or _
        e.Item.ItemType = ListItemType.Item Then
            Dim drow As DataGridItem
            Dim lbl As Label
            drow = e.Item
            lbl = CType(drow.Controls(0).Controls(1), Label)
            If lbl.Text = "True" Then
                e.Item.BackColor = Color.Beige
            Else
                e.Item.BackColor = Color.Red
            End If
        End If
    End Sub

    Function CreateDataSource() As DataTable
        Dim dt As New DataTable
        Dim dr As DataRow
        dt.Columns.Add(New DataColumn _
        ("IntegerValue", GetType(Int32)))
        dt.Columns.Add(New DataColumn _
        ("StringValue", GetType(String)))
        dt.Columns.Add(New DataColumn _
        ("CurrencyValue", GetType(Double)))
        dt.Columns.Add(New DataColumn _
        ("Boolean", GetType(Boolean)))
        Dim i As Integer
        For i = 0 To 4
            dr = dt.NewRow()
            dr(0) = i
            dr(1) = "Item " + i.ToString()
            dr(2) = 1.23 * (i + 1)
            dr(3) = (i = 4)
            dt.Rows.Add(dr)
        Next i
        Return dt
    End Function 'CreateDataSource

            <asp:datagrid id="DataGrid1" runat="server"
autogeneratecolumns="False">
                <columns>
                    <asp:templatecolumn>
                        <itemtemplate>
                            <asp:Label runat="server"  Text='<%#
DataBinder.Eval(Container, "DataItem.Boolean") %>'>
                            </asp:label>
                        </itemtemplate>
                    </asp:templatecolumn>
                </columns>

Hi Javier,

Following code sample shows how to change a cell back
color according to its value:

ListItemType itemType = e.Item.ItemType;

if (itemType != ListItemType.Header && itemType !=
ListItemType.Pager && itemType != ListItemType.Footer &&
itemType != ListItemType.Seperator){

    DataRowView drv = (DataRowView)e.Item.DataItem;
    bool bData = (bool)drv[colIndex];
    TableCell cell = e.Item.Cells[colIndex];

    if (bData){
        cell.BackColor = Color.Red;
    }
}

By the way, it's better to code above logic in ItemCreated.
