  Hi,

  How do you modify the code below to also highlight partial string match?

  If C1AOP5(e.Row, e.Col) = FormGlobalMain.TextBox1.Text Then
  
  e.CellStyle.BackColor = Color.Red
  
  e.CellStyle.ForeColor = Color.White
  
  End If

  Thanks,

  Victor

  Hi,

  You need to do a custom drawing if you need to highlight the string match. You can use the OwnerDrawCell event of the TrueDbgrid to custom draw the cell contents, you need to first set the OwnerDraw property of all DisplayColumns to true, for the OwnerDrawCell event to fire. In the owner draw cell, you can use the MeasureCharacterRanges method to get the bounds of the match and then redraw the text after drawing the filled highlight rectangle for it. Please refer to the sample attached.
  
  For info on MeasureCharacterRanges, please visit :
