Nice.

Currently, it takes about a second for the blank custom calendar grid to be created. This time is noticeable, and even moreso when several months, thus several forms, are required.

I am wondering if an already created form can be cloned/duplicated - events without creating the entire form?

Or, can the grid, with the created cell layout, be copied to another new grid?

I have attached a screenshot of the blank calendar layout. The grey cells are where the data shall go, just above it shall show the relevant day number.

I would need to see your code in order to give any performance advice.  Usually, performance problems are related to a lack of BeginUpdate..EndUpdate calls.

Ok.

I came across this bit of Delphi code, its for a Panel, but says it would work for any component.

Don't know if it applies, but the quest for a solution led me there.

Okay, I got your form via email.

I'm seeing 356 msecs for the creation time here using IE11, not 1 second.  In your BuildGrid method, you definitely want to add this:

 grdCalendar.BeginUpdate;
 try

 finally
    grdCalendar.EndUpdate;
 end;

But, that didn't affect the time that much here.  In general, any other type of time that is over-and-above the built-in TCalendar is due to the fact that you're using a form instead of just a straight up custom TControl-descendant.

No, it doesn't apply.

I meant in terms of clicking a button to create it and having it display on screen.

Same here. No difference.

What I would like to do is run frmBlankCalendar.Create() so procedure BuildGrid is run once - thus creating grdCalendar. So, a blank Calendar grid is available for cloning/duplicating.

Can a copy of the grdCalendar be used as a new grid component named say grdMonthJan2016.

I just realised I didn't send another related program. Shall email it.

Trinione,

This won't work - to create a duplicate requires *creating another copy* that will be the target of the duplication.  You're not buying yourself any time savings.

I wouldn't go down that route.  You're just dancing around the issue, which is that this should be created as a normal control, not a form.  A normal control doesn't need form persistence and other things that add time to the creation of the control.

Ok. I'm gonna take off my dancing shoes and create a custom control.

Since this is a TGrid component in the main, I take it I will have to start from there.

Looking thru the manual I am not seeing any info on Custom Control creation. Can you point me in the right direction with any docs or threads on here.

To be clear - I can run my app with what I have got, I was just trying to speed it up so this is not Critical. But, I would use this opp to learn the Custom Control creation as well as to offer a faster response in version 2 of my product.

Found this on YouTube. Going to start here.

Tim:
For manual grids, can new Properties SetCols and SetRows be added at some point?

So, to define a grid with six columns would be grdName.SetCols(6) and twelve rows, grdName.SetRows(12).

Or, add a parameter to allow NewColumn(6) and InsertRow(12).
