2 Sep 202220 minutes to read
A column template is used to customize the column’s look. The following code example explains how to define the custom template in Gantt using the Template property.
<ejs-gantt id='Gantt' dataSource="ViewBag.dataSource" height="450px" resources="ViewBag.projectResources">
<e-gantt-taskfields id="TaskId" name="TaskName" startDate="StartDate"
endDate="EndDate" duration="Duration" progress="Progress" child="SubTasks" resourceInfo="ResourceId">
</e-gantt-taskfields>
<e-gantt-resourcefields id="ResourceId" name="ResourceName"> </e-gantt-resourcefields>
<e-gantt-columns>
<e-gantt-column field="TaskId" headerText="Task Id" width="50"></e-gantt-column>
<e-gantt-column field="TaskName" headerText="Task Name" width="250"></e-gantt-column>
<e-gantt-column field="ResourceId" headerText="Resources" template="#columnTemplate"></e-gantt-column>
<e-gantt-column field="StartDate"></e-gantt-column>
<e-gantt-column field="Duration"></e-gantt-column>
<e-gantt-column field="Progress"></e-gantt-column>
</e-gantt-columns>
