How to disable particular lines in EditControl?

Platform: WinForms |
Control: EditControl |
Published Date: February 13, 2015 |
Last Revised Date: May 24, 2019

You can disable particular lines in EditControl by using its MarkAsReadOnly function.  This function helps to set back color and fore color for the disabled line. The following code example demonstrates the same.

C#

void Form1_Load(object sender, EventArgs e)
{
//Sets text as readonly
this.editControl1.MarkAsReadOnly(new Point(1, 2), new Point(1, 3), Color.DarkGray, Color.White);
}

VB

Private Sub Form1_Load(ByVal sender As Object, ByVal e As EventArgs)
'Sets text as readonly
Me.editControl1.MarkAsReadOnly(New Point(1, 2), New Point(1, 3), Color.DarkGray, Color.White)
End Sub

The following screenshot illustrates the output.
