Following code snippet helps to achieve this requirement.


//Find the Selected text and highlight it.
IBackgroundFormat format =
editControl1.RegisterBackColorFormat(Color.Yellow, Color.Green);
if (this.editControl1.SelectedText != null)
   for (int i = 0; i < this.editControl1.Lines.Count(); i++)
       if (this.editControl1.FindText(this.editControl1.SelectedText))



‘Find the Selected text and highlight it.
Dim format As IBackgroundFormat = editControl1.RegisterBackColorFormat(Color.Yellow, Color.Green)
If Me.editControl1.SelectedText IsNot Nothing Then
   For i As Integer = 0 To Me.editControl1.Lines.Count() - 1
       If Me.editControl1.FindText(Me.editControl1.SelectedText) Then
