Hi,

I have several property grids in my application, and i have noticed that the load time of the application is very long.
Whenever i break in the debugger during the long wait, i see that ProfUI is bussy doing a lot of initializations.

How can this be removed?

Thanks.

Find below a part of the stack when i break the application:

The call stack lists the sequence of calls made by the column alignment algorithm in a property grid window. This algorithm should be invoked only two times for each property grid at startup: first when the property grid is created and second when some property store is displayed in it. This algorithm may be slow only there are too many property items in each grid (e.g. 5000). If it is the case, displaying a splash window could be a good solution. Otherwise, simply analyze how many times the CExtPropertyGridCtrl::OnSize() method is invoked at startup and why the property is resized many times.

Dear support,

I have only two property grids with 20-30 rows in them.
Still this issue is very annoying, and i think that you are grinding something in the initialization phase of the property grids.

Please check it out.

Support - i asked several times already, it is impossible to keep track of old messages in the forum because only 20 or so messages are displayed per page. Please give us a way of displaying more messages/threads per page.

We changed the number of rows in the forum (Flat View) to 50 but we cannot make it customizable now.

To speed up the initialization of the property grid control, please try the following code:

CExtPropertyGridCtrl * pPGC = . . .
CExtPropertyStore * pPS = . . .
            pPGC->SetRedraw( FALSE );
            pPGC->PropertyStoreSet( pPS );
            pPGC->SetRedraw( TRUE );
            pPGC->RedrawWindow( NULL, NULL, RDW_INVALIDATE|RDW_ERASE|RDW_ALL_CHILDREN );

As for the forum, thank you for your suggestion. We will modify the code for the page generation as soon as possible.

It looks as it saves a couple of seconds... thanks.
You made a mistaker in the code it’s RDW_ALLCHILDREN and not RDW_ALL_CHILDREN.
