Rows in Blazor Gantt Chart Component
23 Dec 202324 minutes to read
Row represents task information from the data source, and it is possible to perform the following actions in Gantt Chart rows.
Row height
It is possible to change the height of the row in Gantt Chart by setting row height in pixels to the RowHeight property. The following code example explains how to change the row height in Gantt Chart at load time.
@using Syncfusion.Blazor.Gantt
<SfGantt DataSource="@TaskCollection" RowHeight=60 Height="450px" Width="900px">
<GanttTaskFields Id="TaskId" Name="TaskName" StartDate="StartDate" EndDate="EndDate"
Duration="Duration" Progress="Progress" ParentID="ParentId">
</GanttTaskFields>
</SfGantt>
@code{
private List<TaskData> TaskCollection { get; set; }
protected override void OnInitialized()
{
this.TaskCollection = GetTaskCollection();
}
public class TaskData
{
public int TaskId { get; set; }
public string TaskName { get; set; }
public DateTime StartDate { get; set; }
public DateTime? EndDate { get; set; }
public string Duration { get; set; }
public int Progress { get; set; }
public int? ParentId { get; set; }
}
private static List<TaskData> GetTaskCollection()
{
List<TaskData> Tasks = new List<TaskData>()
{
new TaskData() { TaskId = 1, TaskName = "Project initiation", StartDate = new DateTime(2022, 01, 04), EndDate = new DateTime(2022, 01, 17), },
new TaskData() { TaskId = 2, TaskName = "Identify Site location", StartDate = new DateTime(2022, 01, 04), Duration = "0", Progress = 30, ParentId = 1, },
new TaskData() { TaskId = 3, TaskName = "Perform soil test", StartDate = new DateTime(2022, 01, 04), Duration = "4", Progress = 40, ParentId = 1, },
new TaskData() { TaskId = 4, TaskName = "Soil test approval", StartDate = new DateTime(2022, 01, 04), Duration = "0", Progress = 30, ParentId = 1, },
new TaskData() { TaskId = 5, TaskName = "Project estimation", StartDate = new DateTime(2022, 01, 04), EndDate = new DateTime(2022, 01, 17), },
new TaskData() { TaskId = 6, TaskName = "Develop floor plan for estimation", StartDate = new DateTime(2022, 01, 06), Duration = "3", Progress = 30, ParentId = 5, },
new TaskData() { TaskId = 7, TaskName = "List materials", StartDate = new DateTime(2022, 01, 06), Duration = "3", Progress = 40, ParentId = 5, },
new TaskData() { TaskId = 8, TaskName = "Estimation approval", StartDate = new DateTime(2022, 01, 06), Duration = "0", Progress = 30, ParentId = 5, }
};
return Tasks;
}
}
Expand or collapse row
In Gantt Chart, parent tasks are expanded/collapsed by using expand/collapse icons, expand all/collapse all toolbar items, and public methods. By default, all tasks in Gantt Chart are rendered in expanded state, but you can change this status using the properties below.
Collapse all tasks at Gantt chart load
All tasks available in Gantt Chart are rendered in collapsed state by setting the CollapseAllParentTasks property as true. The following code example shows how to use this property.
@using Syncfusion.Blazor.Gantt
<SfGantt DataSource="@TaskCollection" CollapseAllParentTasks="true" Height="450px" Width="900px">
<GanttTaskFields Id="TaskId" Name="TaskName" StartDate="StartDate" EndDate="EndDate"
Duration="Duration" Progress="Progress" ParentID="ParentId">
</GanttTaskFields>
</SfGantt>
@code{
private List<TaskData> TaskCollection { get; set; }
protected override void OnInitialized()
{
this.TaskCollection = GetTaskCollection();
}
public class TaskData
{
public int TaskId { get; set; }
public string TaskName { get; set; }
public DateTime StartDate { get; set; }
public DateTime? EndDate { get; set; }
public string Duration { get; set; }
public int Progress { get; set; }
public int? ParentId { get; set; }
}
private static List<TaskData> GetTaskCollection()
{
List<TaskData> Tasks = new List<TaskData>()
{
new TaskData() { TaskId = 1, TaskName = "Project initiation", StartDate = new DateTime(2022, 01, 04), EndDate = new DateTime(2022, 01, 17), },
new TaskData() { TaskId = 2, TaskName = "Identify Site location", StartDate = new DateTime(2022, 01, 04), Duration = "0", Progress = 30, ParentId = 1, },
new TaskData() { TaskId = 3, TaskName = "Perform soil test", StartDate = new DateTime(2022, 01, 04), Duration = "4", Progress = 40, ParentId = 1, },
new TaskData() { TaskId = 4, TaskName = "Soil test approval", StartDate = new DateTime(2022, 01, 04), Duration = "0", Progress = 30, ParentId = 1, },
new TaskData() { TaskId = 5, TaskName = "Project estimation", StartDate = new DateTime(2022, 01, 04), EndDate = new DateTime(2022, 01, 17), },
new TaskData() { TaskId = 6, TaskName = "Develop floor plan for estimation", StartDate = new DateTime(2022, 01, 06), Duration = "3", Progress = 30, ParentId = 5, },
new TaskData() { TaskId = 7, TaskName = "List materials", StartDate = new DateTime(2022, 01, 06), Duration = "3", Progress = 40, ParentId = 5, },
new TaskData() { TaskId = 8, TaskName = "Estimation approval", StartDate = new DateTime(2022, 01, 06), Duration = "0", Progress = 30, ParentId = 5, }
};
return Tasks;
}
}
Define Expand/Collapse Status of Tasks
In Gantt Chart, you can render some tasks in collapsed state and some tasks in expanded state by defining expand status of the task in the data source. This value was mapped to Gantt Chart component by using GanttTaskFields.ExpandState property. The following code example shows how to use this property.
@using Syncfusion.Blazor.Gantt
<SfGantt DataSource="@TaskCollection" CollapseAllParentTasks="true" Height="450px" Width="900px">
<GanttTaskFields Id="TaskId" Name="TaskName" StartDate="StartDate" EndDate="EndDate"
Duration="Duration" Progress="Progress" ParentID="ParentId" ExpandState="isExpand">
</GanttTaskFields>
</SfGantt>
@code{
private List<TaskData> TaskCollection { get; set; }
protected override void OnInitialized()
{
this.TaskCollection = GetTaskCollection();
}
public class TaskData
{
public int TaskId { get; set; }
public string TaskName { get; set; }
public DateTime StartDate { get; set; }
public DateTime? EndDate { get; set; }
public string Duration { get; set; }
public int Progress { get; set; }
public int? ParentId { get; set; }
public bool isExpand { get; set; }
}
private static List<TaskData> GetTaskCollection()
{
List<TaskData> Tasks = new List<TaskData>()
{
new TaskData() { TaskId = 1, TaskName = "Project initiation", StartDate = new DateTime(2022, 01, 04), EndDate = new DateTime(2022, 01, 17), isExpand = true },
new TaskData() { TaskId = 2, TaskName = "Identify Site location", StartDate = new DateTime(2022, 01, 04), Duration = "0", Progress = 30, ParentId = 1, },
new TaskData() { TaskId = 3, TaskName = "Perform soil test", StartDate = new DateTime(2022, 01, 04), Duration = "4", Progress = 40, ParentId = 1, },
new TaskData() { TaskId = 4, TaskName = "Soil test approval", StartDate = new DateTime(2022, 01, 04), Duration = "0", Progress = 30, ParentId = 1, },
new TaskData() { TaskId = 5, TaskName = "Project estimation", StartDate = new DateTime(2022, 01, 04), EndDate = new DateTime(2022, 01, 17), isExpand = false },
new TaskData() { TaskId = 6, TaskName = "Develop floor plan for estimation", StartDate = new DateTime(2022, 01, 06), Duration = "3", Progress = 30, ParentId = 5, },
new TaskData() { TaskId = 7, TaskName = "List materials", StartDate = new DateTime(2022, 01, 06), Duration = "3", Progress = 40, ParentId = 5, },
new TaskData() { TaskId = 8, TaskName = "Estimation approval", StartDate = new DateTime(2022, 01, 06), Duration = "0", Progress = 30, ParentId = 5, }
};
return Tasks;
}
}
Customize expand and collapse action
You can use GanttEvents to handle on expand action, Expanding and Expanded events will be triggered with current expanding row’s information. Similarly, on collapse action, Collapsing and Collapsed events will be triggered. Using these events and their arguments, you can customize the expand/collapse action. The following code example shows how to prevent the particular row from expand/collapse action using the Expanding and Collapsing events.
@using Syncfusion.Blazor.Gantt
<SfGantt DataSource="@TaskCollection" Height="450px" Width="900px">
<GanttTaskFields Id="TaskId" Name="TaskName" StartDate="StartDate" EndDate="EndDate"
Duration="Duration" Progress="Progress" ParentID="ParentId">
</GanttTaskFields>
<GanttEvents Collapsing="Collapsing" Expanding="Expanding" TValue="TaskData"></GanttEvents>
</SfGantt>
@code{
public void Collapsing(Syncfusion.Blazor.TreeGrid.RowCollapsingEventArgs<TaskData> args)
{
if (args.Data.TaskId == 1)
{
args.Cancel = true;
}
}
public void Expanding(Syncfusion.Blazor.TreeGrid.RowExpandingEventArgs<TaskData> args)
{
if (args.Data.TaskId == 5)
{
args.Cancel = true;
}
}
private List<TaskData> TaskCollection { get; set; }
protected override void OnInitialized()
{
this.TaskCollection = GetTaskCollection();
}
public class TaskData
{
public int TaskId { get; set; }
public string TaskName { get; set; }
public DateTime StartDate { get; set; }
public DateTime? EndDate { get; set; }
public string Duration { get; set; }

public int? ParentId { get; set; }
}
private static List<TaskData> GetTaskCollection()
{
List<TaskData> Tasks = new List<TaskData>()
{
new TaskData() { TaskId = 1, TaskName = "Project initiation", StartDate = new DateTime(2022, 01, 04), EndDate = new DateTime(2022, 01, 17), },
new TaskData() { TaskId = 2, TaskName = "Identify Site location", StartDate = new DateTime(2022, 01, 04), Duration = "0", Progress = 30, ParentId = 1, },
new TaskData() { TaskId = 3, TaskName = "Perform soil test", StartDate = new DateTime(2022, 01, 04), Duration = "4", Progress = 40, ParentId = 1, },
new TaskData() { TaskId = 4, TaskName = "Soil test approval", StartDate = new DateTime(2022, 01, 04), Duration = "0", Progress = 30, ParentId = 1, },

};
return Tasks;
}
}Customize rows and cells
While rendering the Tree Grid part in Gantt Chart, the RowDataBound and QueryCellInfo events trigger for every row and cell. Using these events, you can customize the rows and cells. To customize the appearance of a row on the chart side by using the QueryChartRowInfo event. The following code example shows how to customize the cell and row elements using these events.

Styling alternate rows
You can change the background colour of alternative rows in Gantt chart by overriding the class as shown below.
.e-altrow, tr.e-chart-row:nth-child(odd) {
background-color: #f2f2f2;
}@using Syncfusion.Blazor.Gantt

Accessing row task model information programmatically
The Blazor Gantt Chart Component provides a method called GetRowTaskModel that can be used to obtain the values associated with task model details. These details include the level, expanded status, task width, task left, task progress width and more.
This is demonstrated in the below sample code, where the GetRowTaskModel method is called on selecting the row, which returns the value of the task model details of the selected record.
@using Syncfusion.Blazor.Gantt
@using Syncfusion.Blazor.Grids;

Clip mode
The clip mode provides options to display its overflow cell content and it can be defined by the GanttColumn.ClipMode property.
The following are three types of ClipMode:
-
Clip: Truncates the cell content when it overflows its area. -
Ellipsis: Displays ellipsis when content of the cell overflows its area. -
EllipsisWithTooltip: Displays ellipsis when content of the cell overflows its area; it displays the tooltip content when hover over ellipsis.
NOTE
By default, all the column’s
ClipModeproperty is defined asEllipsisWithTooltip.
Cell tooltip
You can enable the Grid cell tooltip by setting the GanttColumn.ClipMode property to EllipsisWithTooltip.
