Code Example: Changing the xamGantt columns

Description

The code example shows you how to modify the columns set. It creates a project table and sets the desired project columns. Then, the project table is specified in the Project view and it is used by the xamGantt .

The code example includes a collection of tasks that can be used to better emphasis the days with changed working time when compared to those ones with the default working time.

Prerequisites

To complete the code example, you should have a xamGantt project . You can follow the instructions in Adding xamGantt to a Page in order to create a sample xamGantt project.

Then, you need to change the view model of the sample project. The following classes should be present:

  • ProjectTableCollection - To see the code for this class, please refer to the ProjectTableCollection code section below.

  • ProjectViewCollection - To see the code for this class, please refer to ProjectViewCollection code section below.

After you change the view model of the sample project, then you have to replace the mark-up with those one shown in this topic.

Preview

This is a preview of the completed sample project. You can see that right after the ID column, the Constraint Type and Constraint Date columns are displayed. This is a different arrangement from the default.
