Hello Olli,

Thank you for writing.

You can access the DateTime editor in the CellEditorInitialized event, for example:

I hope this helps. All the best,

hi, Peter!
thanks a lot for your code - it works perfectly!

as far as i am a little bit lazy, and the project has a set of gridviews with the same requirements, i created an extension class based on your example:

public static class Extensions
{
public static DateTime DatePickerMinDate = new DateTime(1900, 01, 01);
public static DateTime DatePickerNullDate = DatePickerMinDate;
public static void SetDateRestriction(this RadGridView theGrid)
{
theGrid.CellEditorInitialized -= theGrid_CellEditorInitialized;
theGrid.CellEditorInitialized +=new GridViewCellEventHandler(theGrid_CellEditorInitialized);
}

static void theGrid_CellEditorInitialized(object sender, GridViewCellEventArgs e)
{
  RadDateTimeEditor editor = e.ActiveEditor as RadDateTimeEditor;
if (editor != null)
{
RadDateTimeEditorElement element = editor.EditorElement as RadDateTimeEditorElement;
element.MinDate = DatePickerMinDate;
element.NullDate = DatePickerNullDate;
}
}
}

so the only thing left to do is just attaching date restrictions to the required editable gridview having datetime cells - it is easily done by calling extension method after initializing control, for example:

public partial class PaymentHistoryView: UserControl 
{
public PaymentHistoryView()
{
InitializeComponent();

PaymentHistoryGridView.SetDateRestriction();
}

// ...
}

the realization is not very flexible, but it meets all current requirements and it can be upgraded easily if needed.

thanks again for your help.
