ITextElement : ArcObject C# Visual Studio 10 - Arcgis 10.1

The Idea is add a Text to the map, it is working fine except the COLOR, it does not take the Color defined in pRGBcolor object.

IRgbColor pRgbcolor = new RgbColorClass();

pRgbcolor.Blue = 0;

pRgbcolor.Green = 255;

pRgbcolor.Red = 0;

IMask pMask = new TextSymbolClass();

pMask.MaskStyle = esriMaskStyle.esriMSHalo;

pMask.MaskSize = 2;

ITextElement pTextElement = new TextElementClass();

IElement pElement = pTextElement as IElement;

pElement.Geometry = pPagePt;

ITextSymbol pTextSymbol = new TextSymbolClass();

pTextSymbol.Color = pRgbcolor;

pTextSymbol = pMask as ITextSymbol;

pTextElement.Symbol = pTextSymbol as ITextSymbol;

pTextElement.Text = "Test";

pGraphicCont.AddElement(pElement, 0);

pMxDoc.ActivatedView.PartialRefresh(esriViewDrawPhase.esriViewGraphics, null, null);

You are creating two TextSymbols, setting the color on the second, then throwing the second away with:

pTextSymbol = pMask as ITextSymbol;

IRgbColor pRgbcolor = new RgbColorClass();
pRgbcolor.Blue = 0;
pRgbcolor.Green = 0;
pRgbcolor.Red = 255;

IMask pMask = new TextSymbolClass();
pMask.MaskStyle = esriMaskStyle.esriMSHalo;
pMask.MaskSize = 2;

ITextSymbol pTextSymbol = new TextSymbolClass();

pTextSymbol = pMask as ITextSymbol;
pTextSymbol.Color = pRgbcolor;

ITextElement pTextElement = new TextElementClass();

pTextElement.Symbol = pTextSymbol;
pTextElement.Text = a;
IElement pElement = pTextElement as IElement;
pElement.Geometry = pLoc;
pGraphicCont.AddElement(pElement, 0);
pMxDoc.ActivatedView.PartialRefresh(esriViewDrawPhase.esriViewGraphics,
null, null);

Thanks Chris, I ended up with this code and its works.

You're still creating then throwing away the second instance.

Change::

ITextSymbol pTextSymbol = new TextSymbolClass();

pTextSymbol = pMask as ITextSymbol;

To:

ITextSymbol pTextSymbol = pMask as ITextSymbol;
