GridViewDateTimeColumn Dropdown Calendar showing "Footer"

[Dev J]

Just a note to everyone out there. We just upgraded to Q1 2010 and suddenly the drop-down calendar on all GridViewDateTimeColumn columns in our RadGridViews started showing a "footer" (displays the current date/time and has "Clear" and "Now" buttons). None of the other similar controls (RadDateTimePicker, etc.) are doing this. This made the UI inconsistent, so I came up with code to hide the "footer" for GridViewDateTime columns:

 

    Private Sub rgvGrid_CellEditorInitialized(ByVal sender As Object, _
                                              ByVal e As Telerik.WinControls.UI.GridViewCellEventArgs) _
                                              Handles rgvGrid.CellEditorInitialized

        If TypeOf rgvNotes.CurrentColumn Is GridViewDataColumn Then

            Select Case DirectCast(rgvNotes.CurrentColumn, GridViewDataColumn).UniqueName

                Case "SomeColumnName"

                    Dim activeEditor As RadDateTimeEditor = TryCast(rgvNotes.ActiveEditor, RadDateTimeEditor)

                    If activeEditor IsNot Nothing Then

                        Dim editorElement As RadDateTimeEditorElement _
                            = TryCast(activeEditor.EditorElement, RadDateTimeEditorElement)

                        If editorElement IsNot Nothing Then

                            Dim dateTimePickerCalendar As RadDateTimePickerCalendar _
                                = TryCast(editorElement.GetCurrentBehavior(), RadDateTimePickerCalendar)

                            If dateTimePickerCalendar IsNot Nothing Then

                                dateTimePickerCalendar.Calendar.ShowFooter = False

                            End If

                        End If

                    End If

            End Select

        End If

    End Sub

Hi Dev J,

Thank you for your feedback.

We decided to change the default behavior in RadGridView due to the numerous requests concerning Clear and Now buttons visible by default. Your Telerik points have been updated for your community effort.

If you have additional feedback to share, feel free to contact me.

I am using Q1 2009 and I cant see 'activeEditor.EditorElement' in my RadDateTimeEditor class ?
And also plese tell me whether I can show a list of years like from 2000 to 2010 on my calender somewhere?

Please help...

Hi Robert,

Actually, the footer of RadDateTimePicker in RadGridView is shown by default in our latest version. The Clear button, however, is not visible by default. If you want to show it, you can do it as demonstrated below:

void radGridView1_CellEditorInitialized(object sender, GridViewCellEventArgs e)
{
    RadDateTimeEditor editor = this.radGridView1.ActiveEditor as RadDateTimeEditor;
    if (editor != null)
    {
        RadDateTimeEditorElement editorElement = (RadDateTimeEditorElement)editor.EditorElement;
        RadDateTimePickerCalendar calendarBehavior = editorElement.GetCurrentBehavior() as RadDateTimePickerCalendar;
        RadCalendar calendar = calendarBehavior.Calendar as RadCalendar;
        RadCalendarElement calendarElement = calendar.CalendarElement as RadCalendarElement;
        calendarElement.CalendarStatusElement.ClearButton.Enabled = true;
        calendarElement.CalendarStatusElement.ClearButton.Visibility = Telerik.WinControls.ElementVisibility.Visible;
    }
}

Please note that the above code snippet will work only with the latest versions of RadControls for WinForms. I would recommend updating to our latest release Q3 2010 SP1 (v2010.3.10.1215). You should be able to immediately notice the improvements that we have made during the last two years.

As to the year list, RadCalendar does not support this feature. You can find the PITS item for this task here. In case it gathers enough votes, we will consider implementing it in one of our next versions.

If you have additional questions, feel free to contact us.

All the best,

Hi Nikolay,

Many thanks for your reply, but I would like to let you know that I am using quite a lot of controls in one project but if I upgrade it to the latest version how many thing would it change in the previous controls and how would it effect the previous controls because I dont want to get into a big hassle upgrading these controls.

And this code is almost useless with Q1 2009 because as I mentioned earlier I cant see 'editor.EditorElement'  in RadDateTimeEditor class.

Please advice what should I do?

Many thanks,

Robert

Hi Robert,

The changes that we have introduced during the last two years are listed in our Release Notes. The breaking changes are marked in red for better readability. I would suggest that you update your project as soon as possible, because the longer you wait, the more difficult the upgrade process might be. In addition, according to our general policy, we do not support versions older than one year.

If you do not have the time to update now, we will make an exception for you and will provide you with assistance for your enquiry. Please note, however, that in this case I would kindly ask you to ask the purchase holder of your license to add you as a license developer. Once we verify the status of your account, we provide you with the solution to your question about the footer in RadDateTimeEditor.

All the best,
