What is the best method of replacing the default labels in the LabelCollection with my own custom labels?  I have tried clearing the LabelCollection, then adding my own labels with the desired text and colors(this information is stored in a database).  However,everytime I run the program the labels get a different LableID than on the previous run and the appointments using those labels don't recognize the new ones.  As a workaround I am replacing the text of the default labels in the LabelCollection, but this doesn't seem like a very good permanent solution.  Thanks in advance.

The best way for you is to bind LabelStorage to your data. It can be made in the same way
as for AppointmentStorage. You should set mappings, DataSource and DataMember properties.
To have the same label Id every time, you should set mapping of the primary key of your
labels table to IdMapping (if your key is Guid) or to IndexMapping (if your key is
integer).

What kind of value should be stored for the color?  Currently I am storing a hex aRGB value (#FF0000FF) but this doesn't seem to work.

 

* Nevermind, I found one of the sample databases with Color values in it.  Thanks for your help. 

 

Binding had no effect on the Label Id.  Every time the application is run the labels come up with different Label Id's than the previous run.  Any appointment made using that label does not have a label selected, or associated with it.  I am assuming the Label Id in AppointmentProperties tells the appointment which label to use, is this right?  I have set up the binding as such:

 <c1sched:NestedPropertySetter PropertyName="DataStorage.LabelStorage.DataSource" Value="{DynamicResource dataSet1}"/>

<c1sched:NestedPropertySetter PropertyName="DataStorage.LabelStorage.DataMember" Value="TaskType"/>

<c1sched:NestedPropertySetter PropertyName="DataStorage.LabelStorage.Mappings.IndexMapping.MappingName" Value="PK_TaskType"/>

<c1sched:NestedPropertySetter PropertyName="DataStorage.LabelStorage.Mappings.ColorMapping.MappingName" Value="TaskColor"/>

<c1sched:NestedPropertySetter PropertyName="DataStorage.LabelStorage.Mappings.TextMapping.MappingName" Value="TaskDescLong"/>

I just tried to make a sample. It seems to me, that it is a bug in our code. Your code is
correct and should work as it is.
Sorry for inconvenience, we'll make the fix available as soon as possible. If it is not
critical for you, you can change primary key of your labels table to guid and set
IdMapping, it should work fine with the current version.
