Disable the GridViewDateTimeColumn TextBox

[MikeB]

Hi,

Is there a way to set the input (TextBox) control of the GridViewDateTimeColumn to ReadOnly or Enabled = false?

We would like to have the user select the date from the drop-down calendar only.  And not allow anything to be entered into the TextBox.

Thanks,

Mike

Hello Michael,

Thank you for writing.

You can do that by accessing the date time editor in the CellEditorInitialized event, from where you can get the text box and make it read only. Here is an example:

void radGridView1_CellEditorInitialized(object sender, GridViewCellEventArgs e)
{
    RadDateTimeEditor dateEditor = e.ActiveEditor as RadDateTimeEditor;
    if (dateEditor != null)
    {
        RadDateTimeEditorElement dateEditorElement = (RadDateTimeEditorElement)dateEditor.EditorElement;
        dateEditorElement.TextBoxElement.TextBoxItem.ReadOnly = true;
    }
}

I hope that you find this information useful. Should you have any other questions, do not hesitate to contact us.

I have a follow up question.

The Calendar Popup is only shown when the drop down arrow is clicked.

Is there a way to display the Calendar Popup in the CellBeginEdit or CellEditorInitialized?  And of course, close when the operator clicks on a date or clicks the drop down arrow.

Thanks again,
Mike

Hello Michael,

Here is one way to do that:

void radGridView1_CellEditorInitialized(object sender, GridViewCellEventArgs e)
{
    RadDateTimeEditor dateEditor = e.ActiveEditor as RadDateTimeEditor;
    if (dateEditor != null)
    {
        RadDateTimeEditorElement dateEditorElement = (RadDateTimeEditorElement)dateEditor.EditorElement;
        RadDateTimePickerCalendar calendarBehavior = dateEditorElement.GetCurrentBehavior() as RadDateTimePickerCalendar;
        calendarBehavior.PopupControl.PopupClosed -= PopupControl_PopupClosed; //avoids multiple subscriptions
        calendarBehavior.PopupControl.PopupClosed += PopupControl_PopupClosed;
        calendarBehavior.ShowDropDown();
    }
}

void PopupControl_PopupClosed(object sender, RadPopupClosedEventArgs args)
{
    radGridView1.EndEdit();
}

I hope that the provided information addresses your question.
