protected override void OnClick() 

{ 

// 

// TODO: Sample code showing how to access button host 

// 

ArcMap.Application.CurrentTool = null; 

IApplication application = ArcMap.Application; 

IMxDocument mxdoc = application.Document as IMxDocument; 

IFeatureLayer feaLayer = mxdoc.FocusMap.get_Layer(0) as IFeatureLayer; 

ILegendInfo legendInfo = feaLayer as ILegendInfo; 

ILegendGroup legendGrp = legendInfo.get_LegendGroup(0); 



ILegendClass pLegendClass = legendGrp.get_Class(0); 

ISymbol symbol = pLegendClass.Symbol; 

ISymbolSelector symbolSelector = new SymbolSelectorClass(); 

bool bok = false; 

symbolSelector.AddSymbol(symbol); 



bok = symbolSelector.SelectSymbol(0); 

if (bok) 

{ 

pLegendClass.Symbol = symbolSelector.GetSymbolAt(0); 

} 

}
