FindRange with search up option

[Craig Timmerman]

I can't seem to make FindRange search up.

I am using FindRange with a regexp to first find a specific block of text:

// Search from the top to bottom looking for "NAME:func1"
CoordinatePoint stpt = this.Editor.ConvertVirtualPointToCoordinatePoint(1,1);
ITextRange range = this.Editor.FindRange("\bNAME\b.*\bfunc1\b", stpt, null, true, true, false, true);

I then want to start from the point found and search backwards (up) to find another string:


CoordinatePoint pt = this.Editor.ConvertVirtualPointToCoordinatePoint(range.Start.PhysicalPoint.Position, range.Start.PhysicalPoint.Line);
this.Editor.FindRange("\bBEGIN_DEFINITION\b", pt, stpt, true, true, true, true);

The range returned by the second call is always null. The following text is that is in the Edit Control


#BEGIN_DEFINITION
#NAME:func1
#TYPE:codeblock
#
# BEGIN_COMMENT
#
# END_COMMENT
#
#END_DEFINITION

I forgot to mention, this is Syncfusion 4.2.0.37

Hi Craig,

It is possible to search up using the FindRange method. I have attached a sample that illustrates this. Let me know if this meets your requirements.

Thank you for your patience.
