private void axTOC1_OnDoubleClick(object sender, ITOCControlEvents_OnDoubleClickEvent e) {

esriTOCControlItem itemType = esriTOCControlItem.esriTOCControlItemNone; IBasicMap basicMap = null; ILayer layer = null; object unk = null; object data = null;

axTOC1.HitTest(e.x, e.y, ref itemType, ref basicMap, ref layer, ref unk, refdata);

if (e.button == 1) { if (itemType == esriTOCControlItem.esriTOCControlItemLegendClass) { //取得图例

ILegendClass pLegendClass =((ILegendGroup)unk).get_Class((int)data);

//创建符号选择器SymbolSelector实例

FormSymbolControl SymbolSelectorFrm= newFormSymbolControl(pLegendClass, layer);

if (SymbolSelectorFrm.ShowDialog()== DialogResult.OK) { //局部更新主Map控件

//m_mapControl.ActiveView.PartialRefresh(esriViewDrawPhase.esriViewGeography, null, null);

axMap1.ActiveView.PartialRefresh(esriViewDrawPhase.esriViewGeography, null, null);

//设置新的符号

pLegendClass.Symbol = SymbolSelectorFrm.pSymbol; //更新主Map控件和图层控件 this.axMap1.ActiveView.Refresh(); this.axTOC1.Refresh(); } } } }
