Hi Dmitry,
To change the color for a ColorGroup all you would need to do is call AddColorGroup().
For example in the DynamicSettings sample that ships with Essential Edit, you could add another button say ChangeKeyWordColor and then you could add the following code snippet in it''s click event:
string strTemp = textBoxKeyword.Text;
this.editControl1.AddColorGroup("KeyWord",Color.Red,Color.White,true,true,Syncfusion.Windows.Forms.Edit.EditColorGroupType.RegularText);
editControl1.AddKeyword(strTemp,"KeyWord");
Now if you enter a KeyWord in the anc click on the ChangeKeyWordColor the keywords will be red instead of blue.
Here is the
modified sample.
Take a look and let us know if you have any further questions.
