How to display various activity-attributes within multiple rows in Gantt view

This blog article explains how to configure GroupCalendar in order to show additional activity-attributes within multiple rows in the GroupCalendar’s Gantt view. Each additional attribute of an activity will be shown in a new line.

You have the possibility to configure as many lines as you like, there is no limitation.
For each line, you can define a display name and the associated attribute.
This is globally configured in the general GroupCalendar settings.
To do so, please follow the steps described below.

1. Open your CRM in InternetExplorer.

2. Navigate to Settings within the CRM sitemap. Here, click on Products in the CRM sitemap, tick the checkbox in front of GroupCalendar and click on the [Edit]-button within the CRM menu.

A new window opens. Here, you must define a name of the key in the Name-field and set the IsCached-field on Yes. Furthermore, you must type in a value in the KeyValue-field.

The syntax for the Name-field referring to the attribute description to be displayed is AddGanttAttrDesc[TYPENAME][LINENUMBER]. The syntax for the Name-field referring to the attribute to be shown is AddGanttAttr[TYPENAME][LINENUMBER].
The [TYPENAME] is the entity schema name (e.g. appointment)  and the [LINENUMBER] is the line number of the attribute starting with 1. The first line will always be the subject.

If you want to display an appointment entity with multiple rows, e.g. in the first row the attribute location with the display name Location, in the second row the attribute requiredattendees with the display name Required and in the third row a custom attribute named new_contactid with the description Contact, you have to type in the following key-names and key-values within the settingskey-configuration-window shown in the previous screenshot.






Appointment 1. line, displayname "Location"



Appointment 1. line, attribute "location"



Appointment 2. line, displayname  "Required"



Appointment 2. line, attribute "requiredattendees"



Appointment 3. line, displayname "Contact"



Appointment 3. line, attribute "new_contactid"

After you have typed in the key-name and the key-value, click on the [Save and Close]-button in the CRM menu at the top. Afterwards, start to create a new settingskey with the key-name and the key-value of the attribute or the attribute description-name you want to add next.

In addition, you have to configure in which Gantt-views you want these attributes to be displayed.

This setting is named GanttMultipleLineViews. Possible values are daygantt, weekgantt and monthgantt. The settings can also be combined. If you want to e.g. display the multiple lines in the day- and week-Gantt-view, you have to type in “daygantt,weekgantt” as the value of the setting.
