I am trying to use the DateTime picker custom gridview column type from this MSDN example on How to host controls in DataGridViewCells. I want to display hour and minute in 24 hour format, without seconds or AM PM indicators.
I have set EditingControlFormattedValue to "HH:mm", and when not actually editing the value is displayed correctly.
When editing, if in the constructor of the CalendarEditingControl I set the editing control to CustomFormat = "HH:mm", the control displays the day of week and month. (!?)
When I instead use Format = DateTimePickerFormat.Time, the control shows AM or PM when editing.
How can I persuade this control to display only the parts of the DateTime value that I care about? (C#, VS 2008)
There are a few tweaks you need to to do the linked code to make it work the way you want:
Comment out the hard-coded line in CalendarCell() constructor (this.Style.Format = "d";)
Tell the CalendarEditingControl to use your custom-specified format:
In the designer, set the format you want (EditColumns->DefaultCellStyle->Format)
public void ApplyCellStyleToEditingControl(DataGridViewCellStyle dataGridViewCellStyle)
{
this.Format = DateTimePickerFormat.Custom;
this.CustomFormat = dataGridViewCellStyle.Format;
// ... other stuff
}
