Ok, I found the solution for the first problem, by moving the Locations/Resources initialization and addition from the Calendar's Loaded to it's parent container's Loaded event handler.

So, I changed from this:

<Grid>
    <planner:Calendar x:Name="globalCalendar"  Loaded="globalCalendar_Loaded" .... 

to this:

<Grid Loaded="globalCalendar_Loaded">
    <planner:Calendar x:Name="globalCalendar" .... 

I am still interested in questions #2 , #3 and #4, so, please respond.

Thank You for Your time.

Hi again,

#1. I cannot reproduce the false column header text with the most recent dlls. You can check the attached sample and see that the column names display properly.

#2. The attached sample demonstrates how to do that using custom column header presenters.

#3. This is also demonstrated in the attached sample by using a combination of calendar events and properties, namely, AllowInplaceCreate, AllowInplaceEdit, ItemModifying, and ItemDeleting.

#4. This should be possible by using a custom item presenter. I'll update the sample later to show this.

#5. This cannot be done.

Let me know if this helps.

Meppy

Hi,

I've updated the sample once again to illustrate a possible way to implement #5 - by using several calendar instances, displaying the same schedule.
