dhxCalendar column type data not visible

Dates for Created and Modified are visible in grid, but dates for Due Date and Start Date are invisible in grid.

If I set column type to ed for Due Date and Start Date I can see dates.

The only difference I can see is that Created and Modified come from TIMESTAMPs in a MySQL db while Start Date and Due Date come from TIMEs in a MySQL database.

function dejaTasks()
grid3.setHeader(“Subject,Priority, Due Date, Category, Status, Contact, Location, Project, Note, Start Date, Done, Created, Modified”);
grid3.setColTypes(“ed,ro,dhxCalendar,ed,ed,ed,ed,ed,ro,dhxCalendar,ch,dhxCalendar,dhxCalendar”);//changed 3 and 10 from dhxCalendar
grid3.customGroupFormat = function(text, count)
if(text == " ")
text = “(Blank)”
if(currentGroup == “category”) group = “Category”
else if(currentGroup == “priority”) group = “Priority”
else if(currentGroup == “edate”) group = “Due”
else if(currentGroup == “status”) group = “Status”
else if(currentGroup == “contact”) group = “Contact”
else if(currentGroup == “location”) group = “Location”

	return group + ": " + text + " - " + count + " records"

if( grid3.getColumnId(11) == "Created" || grid3.getColumnId(12) == "Modified") 
	grid3.setDateFormat(getDateFormat() + " " + getTimeFormat(),"%Y-%m-%d %H:%i:%s");
else grid3.setDateFormat(getDateFormat());

	if (ind == 2 || ind == 9 || ind == 11 || ind == 12)
		return false;
	return true;

Unfortunately the issue cannot be reproduced locally.
If the problem still occurs for you, please, provide with a complete demo, where the problem can be reconstructed.

Is it possible to format the date type differently for different dhxCalendar column types?

For example:

Set: ColumnId(11) == “Created” and ColumnId(12) == “Modified”
To: grid3.setDateFormat(getDateFormat() + " " + getTimeFormat(),"%Y-%m-%d %H:%i:%s");


Set: ColumnId(2) == “Due Date” and ColumnId(9) == “Start Date”
To: grid3.setDateFormat("%m-%d-%Y);

Unfortunately the date format is global for the whole grid.
It is not available to set the individual date format for different columns of the grid.
