I have a sfdatagrid with a gridcheckboxcolumn.  I need to update the database field bound to the checkbox when the checkbox becomes checked or unchecked.  I have tried the gridcheckbox and a checkbox imbedded in a datatemplate, but cannot get the database to be updated.

Hi David, 
 
You can get the underlying record values and update it to database fields while we check/uncheck the GridCheckBoxColumn by wiring the CurrentCellValueChanged event.  
 
this.sfGrid.CurrentCellValueChanged += sfGrid_CurrentCellValueChanged; 
 
void sfGrid_CurrentCellValueChanged(object sender, Syncfusion.UI.Xaml.Grid.CurrentCellValueChangedEventArgs args) 
{ 
    int columnIndex = this.sfGrid.ResolveToGridVisibleColumnIndex(args.RowColumnIndex.ColumnIndex); 
 
    if (this.sfGrid.Columns[columnIndex].CellType == "CheckBox") 
    { 
        var record = args.Record; 
    } 
} 
 
Sample:

Private Sub sfGrid_CurrentCellValueChanged(ByVal sender As Object, ByVal args As Syncfusion.UI.Xaml.Grid.CurrentCellValueChangedEventArgs) 
       Dim columnIndex As Integer = Me.sfGrid.ResolveToGridVisibleColumnIndex(args.RowColumnIndex.ColumnIndex) 
 
       If Me.sfGrid.Columns(columnIndex).CellType Is "CheckBox" Then
