Customize the backcolor and forecolor

In Edit control, it is possible customize the Selected text Backcolor and Forecolor by using property named SelectedText and functions named RegisterBackColorFormat and SetSelectionBackColor.

 

RegisterBackColorFormat - To specify required color format.

SetSelectionBackColor - To customize Back color to all the selected text.

SelectedText - To find the selected text.s

 

Following code snippet helps to achieve this requirement.

C#

//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))
         this.editControl1.SetSelectionBackColor(format);
     }
 }

 

VB

‘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
         Me.editControl1.SetSelectionBackColor(format)
       End If
   Next
End If

                             

                                                    Find and highlight the selectedtext in EditControl
