DiagramBase.TableSectionExpanded Event

Raised when the user expands the rows of a table's section by clicking the [+] button in the section’s header row.

Namespace: MindFusion.Diagramming
Assembly: MindFusion.Diagramming

 Syntax

C#

public event EventHandler<RowEventArgs> TableSectionExpanded

Visual Basic

Public Event TableSectionExpanded As EventHandler(Of RowEventArgs)

 Event Data

TableSectionExpanded event handlers receive an argument of type RowEventArgs. The following RowEventArgs members provide information relevant to the event:

Member name	Description
Table	The TableNode that contains the expanded rows.
RowIndex	Index of the header row of the expanded section.

 Remarks

A header row is a row whose Header property is enabled. Such rows display a [±] button which can be used to expand or collapse all rows below a header up to the next header. TableSectionExpanded is raised when a user clicks the [+] button, but not when Expanded is set to true programmatically.

 Example

The code below changes the color of the first cell of a header row when the table section defined via that row is expanded:

C#

void diagram_TableSectionExpanded(object sender, RowEventArgs e)
{
    e.Table[0, e.RowIndex].Brush = new MindFusion.Drawing.SolidBrush(Color.Blue);
}

Visual Basic

Private Sub Diagram_TableSectionExpanded(ByVal sender As Object, ByVal e As MindFusion.Diagramming.RowEventArgs)Handles Diagram.TableSectionExpanded
    e.Table(0, e.RowIndex).Brush = New MindFusion.Drawing.SolidBrush(Color.Blue)
End Sub
