I am trying to use the ChartDrawItem event. I put a Consule.WriteLine() to see when it's called. I realize as long my ultrachart is open, it keeps looping in it. Is this suppose to be like that? I simply want to make use of the Primivitive to change color of my 3D chart. I only need to run one time when I load the ultraChart.

Does anyone know why it goes infinite loop in ChartDrawItem? 

if

(e.HasData && this.ultraChart1.ChartType == ChartType.HeatMapChart3D)

{

Path p = e.Primitive as Path;

if (e.Primitive.Row != -1)

{

int division = dt.Rows.Count / 4;

if (e.Primitive.Row < division)

{

SolidBrush sb = new SolidBrush(ultraColorPicker1.Color);

p.Brush = sb;

p.PE.Stroke = ultraColorPicker1.Color;

}

else if (e.Primitive.Row < division * 2)

{

SolidBrush sb = new SolidBrush(ultraColorPicker2.Color);

p.Brush = sb;

p.PE.Stroke = ultraColorPicker2.Color;

}

else if (e.Primitive.Row < division * 3)

{

SolidBrush sb = new SolidBrush(ultraColorPicker3.Color);

p.Brush = sb;

p.PE.Stroke = ultraColorPicker3.Color;

}

else if (e.Primitive.Row == dt.Rows.Count - 1)

{

SolidBrush sb = new SolidBrush(ultraColorPicker4.Color);

p.Brush = sb;

p.PE.Stroke = ultraColorPicker4.Color;

}

else

SolidBrush sb = new SolidBrush(ultraColorPicker4.Color);

p.Brush = sb;

p.PE.Stroke = ultraColorPicker4.Color;

}

}

true;

}
