Hi We have Datagrid_LoadingRow in silverlight with the help of that you get the each row in datagrid after paging. Customerdatagrid.LoadingRow += new EventHandler (Customerdatagrid_LoadingRow); void Customerdatagrid_LoadingRow(object sender DataGridRowEventArgs e) { // CustomerDetail is a table at service side ServiceReference1.CustomerDetail clist = e.Row.DataContext as ServiceReference1.CustomerDetail; DataGridRow dataGridrow = DataGridRow.GetRowContainingElement(e.Row); //here you will get content of each row FrameworkElement el; // Here i just take 1 column you can take what you want el = this.Customerdatagrid.Columns[1].GetCellContent(e.Row); DataGridCell changeCell = GetParent(el typeof(DataGridCell)) as DataGridCell; } private FrameworkElement GetParent(FrameworkElement child Type targetType) { object parent = child.Parent; if (parent != null) { if (parent.GetType() == targetType) { return (FrameworkElement)parent; } else { return GetParent((FrameworkElement)parent targetType); } } return null; } Hope this will help you. Thanks.
