How do I draw indicators in the indicator margin of the EditControl ?

Platform: WinForms |
Control: EditControl |
Published Date: April 30, 2011 |
Last Revised Date: July 10, 2014


The indicators can be set in the indicator margin area by handling the DrawLineMark event associated with the EditControl as shown in code below.


private void editControl1_DrawLineMark(object sender, Syncfusion.Windows.Forms.Edit.DrawLineMarkEventArgs e)


if( e.VirtualLine % 2 == 0 )


Brush brush = new SolidBrush(Color.LightSalmon);

e.Graphics.FillRectangle(brush, e.MarkRect);

e.Graphics.DrawRectangle(Pens.IndianRed, e.MarkRect);




Private Sub editControl1_DrawLineMark(sender As Object, e As Syncfusion.Windows.Forms.Edit.DrawLineMarkEventArgs) Handles editControl1.DrawLineMark

If e.VirtualLine Mod 2 = 0 Then

Dim brush = New SolidBrush(Color.LightSalmon)

e.Graphics.FillRectangle(brush, e.MarkRect)

e.Graphics.DrawRectangle(Pens.IndianRed, e.MarkRect)

End If

End Sub 'editControl1_DrawLineMark
