Essential Gantt for WPF is a MS Project-like Project Viewer with built-in grid, schedule and resource assignment constraints. It is designed to assist project managers in developing plans, assigning resources to the task, tracking task progress and so on. Some of the key features of Gantt control are: drag support for increasing and decreasing the Start and Finish Date of the Task, Drag and Drop support for the task within a row and automatic data synchronization between Grid and Chart. This page has information about the Gantt Control.

To configure the Gantt control in the CodeBehind, create an instance for Gantt Control as shown below
T.Wpf.Controls.TGanttControl gant = this.CurrentDisplay.GetControl("controlname") as T.Wpf.Controls.TGanttControl;
With the instance above, it is possible to access all properties of Gantt Control as shown in the below screenshot
Column Mapping
Click the Add button to add a column to the list.
To map user table column with default column, you need to configure the field and column name properties.
Select Field and map the user column with column name textbox
E.g.: In Field, we selected “TaskId” from the default column and I have mapped user column “ID” to the default “TaskId” column, as in the image above.
Click OK to save the configuration.
Runtime
To view the data in the runtime as shown in the screenshot below, you need to configure DataSource in the Gantt Control configuration window. It can be a tag or a dataset
Samples configurations
Sample 1
Create a tag with a type of DataTable (E.g.: TestTable) as shown in the below screenshot
In CodeBehind DisplayOpening() method, create a datatable and assign it to ‘Tag.TestTable’ as shown in the screenshot below.
public void DisplayOpening()
{
DataTable dt = new DataTable("TaskDetails");
dt.Columns.Add("TaskId", typeof(int));
dt.Columns.Add("TaskName", typeof(string));
dt.Columns.Add("StartDate", typeof(DateTime));
dt.Columns.Add("FinishDate", typeof(DateTime));
dt.Columns.Add("Progress", typeof(Double));
dt.Columns.Add("ParentId", typeof(string));
dt.Columns.Add("PrecedesserTaskId", typeof(string));
dt.Columns.Add("PredecessorDependencyRelation", typeof(string));
dt.Columns.Add("Cost", typeof(int));
dt.Columns.Add("BaseLineCost", typeof(int));
dt.Columns.Add("BaseLineStart", typeof(DateTime));
dt.Columns.Add("BaseLineFinish", typeof(DateTime));
dt.Rows.Add(1, "Adam", new DateTime(2022, 2, 1), new DateTime(2022, 2, 4), 40d, "", "", "", 1000, 999, new DateTime(2022, 2, 1), new DateTime(2022, 2, 5));
dt.Rows.Add(2, "Eve", new DateTime(2022, 2, 7), new DateTime(2022, 2, 9), 40d, 1, "", "", 1000, 800, new DateTime(2022, 2, 7), new DateTime(2022, 2, 12));
dt.Rows.Add(2, "Kain", new DateTime(2022, 2, 7), new DateTime(2022, 2, 9), 40d, 1, "", "", 2000, 2600, new DateTime(2022, 2, 5), new DateTime(2022, 2, 11));
dt.Rows.Add(10, "Hebel", new DateTime(2022, 2, 7), new DateTime(2022, 2, 16), 40d, 1, "", "", 1500, 1600, new DateTime(2022, 2, 6), new DateTime(2022, 2, 17));
dt.Rows.Add(13, "Extraterrestrial", new DateTime(2022, 2, 7), new DateTime(2022, 2, 14), 40d, 10, 14, 1, 1800, 1600, new DateTime(2022, 2, 6), new DateTime(2022, 2, 13));
@Tag.TestTable = dt;
}
In the screenshot above, columns ParentId, PrecedesserTaskId and PredecessorDependencyRelation are string type. Input for these columns should be empty string or NULL if there is no data.
3. In configuration window, Data Source is configured as ‘Tag.TestTable’.
In the example, the table columns are in sync with default table columns, so it is necessary to map the columns
4. Click Ok to save the configuration.
5. Click Actions/Start Runtime to start the test.
6. In Runtime, now it is possible to see the startup window as shown in the screenshot below.
Sample 2
1. Create a tag with a type of DataTable (E.g.: TestTable1) as shown in the screenshot below.
2. In code behind DisplayOpening() method, create a datatable and assign it to ‘Tag.TestTable1’ as shown in the below screenshot.
public void DisplayOpening()
{
DataTable dt1 = new DataTable("TaskDetails");
dt1.Columns.Add("ID", typeof(int));
dt1.Columns.Add("Name", typeof(string));
dt1.Columns.Add("Start", typeof(DateTime));
dt1.Columns.Add("Finish", typeof(DateTime));
dt1.Columns.Add("Progress", typeof(Double));
dt1.Columns.Add("PID", typeof(string));
dt1.Rows.Add(1, "Adam", new DateTime(2022, 2, 1), new DateTime(2022, 2, 4), 40d, "");
dt1.Rows.Add(2, "Eve", new DateTime(2022, 2, 7), new DateTime(2022, 2, 9), 40d, 1);
dt1.Rows.Add(2, "Kain", new DateTime(2022, 2, 7), new DateTime(2022, 2, 9), 40d, 1);
dt1.Rows.Add(10, "Hebel", new DateTime(2022, 2, 7), new DateTime(2022, 2, 16), 40d, 1);
dt1.Rows.Add(13, "Extraterrestrial", new DateTime(2022, 2, 7), new DateTime(2022, 2, 14), 40d, 10);
@Tag.TestTable1 = dt1;
}
In the example, the table columns did not match with the default columns. In this case, it is necessary to map the columns in the configuration window.
Field Name represents default column, and Column Name represents user table column
3. In configuration window, datasource is configured as ‘Tag.TestTable1’
In screenshot above screenshot, columns are mapped with default columns.
4. Click Ok to save the configuration.
5. Click Run Test to start the test
6. In Runtime, now you can able to see the startup window as shown in the below screenshot
Sample 3
In this sample, the data source is a table from SQL server.
1. First, you need to establish connection with your database as shown in the screenshot below.
The screenshot below shows the table from SQL server
In the example, the database table columns did not match with the default columns. In this case, it is necessary to map the columns in the configuration window.
4. In configuration window, Data Source is configured as ‘Dataset.Table.Tasks’.
5. In the screenshot above, columns are mapped with default columns. Click Ok to save the configuration.
6. Click Run Test to start the test.
7. In Runtime, now you can able to see the startup window as shown in the below screenshot
