各位帮我看下为什么以下代码不行。
我想在axMap1中放大后，axMap2中的框能变小，但是现在做出来的axMap2的框不变
private void axMap1_MapViewChanged(object sender, EventArgs e)
{
MapXLib.Feature tempFea; //声明一个图元，用于鹰眼图中创建的矩形框
MapXLib.Points tempPoints = new Points();
MapXLib.Style tempStyle = new Style();
MapXLib.Point ptMap_1 = new MapXLib.Point();
MapXLib.Point ptMap_2 = new MapXLib.Point();
MapXLib.Point ptMap_3 = new MapXLib.Point();
MapXLib.Point ptMap_4 = new MapXLib.Point();
MapXLib.Layer m_layer_Eagle;
MapXLib.Feature m_feature_Eagle;
//设置矩形框四角坐标为主图边框
ptMap_1.Set(axMap1.CtlBounds.XMin, axMap1.CtlBounds.YMin);
ptMap_2.Set(axMap1.CtlBounds.XMax, axMap1.CtlBounds.YMin);
ptMap_3.Set(axMap1.CtlBounds.XMax, axMap1.CtlBounds.YMax);
ptMap_4.Set(axMap1.CtlBounds.XMin, axMap1.CtlBounds.YMax);
//添加点到点集
tempPoints.Add(ptMap_1, 1);
tempPoints.Add(ptMap_2, 2);
tempPoints.Add(ptMap_3, 3);
tempPoints.Add(ptMap_4, 4);
//以下设置边框样式
tempStyle.RegionPattern = FillPatternConstants.miPatternNoFill;
tempStyle.RegionBorderColor = (uint)MapXLib.ColorConstants.miColorBlue;
tempStyle.RegionBorderWidth = 2;
//////////////以下创建临时图层/////////////////////////
MapXLib.LayerInfo tempLayerInfo = new MapXLib.LayerInfoClass();
MapXLib.Fields flds = new MapXLib.FieldsClass();
flds.AddStringField("Name", 100, false);
tempLayerInfo.Type = MapXLib.LayerInfoTypeConstants.miLayerInfoTypeTemp;
tempLayerInfo.AddParameter("Name", "Eagle");
tempLayerInfo.AddParameter("Fields", flds);
m_layer_Eagle = axMap2.Layers.Add(tempLayerInfo, 1); //为鹰眼图添加图层
//////////////以上创建临时图层//////////////////////////
//以下在临时图层添加大小为axMapx2的边界的Rectangle对象
tempFea = axMap2.FeatureFactory.CreateRegion(tempPoints, tempStyle);//创建矩形框
m_feature_Eagle = axMap2.Layers._Item("Eagle").AddFeature(tempFea, new MapXLib.RowValuesClass()); //添加边框到鹰眼图
tempStyle = null;
tempFea.Parts._Item(1).RemoveAll();
tempFea.Parts._Item(1).AddXY(axMap1.CtlBounds.XMin, axMap1.CtlBounds.YMin, 1);
tempFea.Parts._Item(1).AddXY(axMap1.CtlBounds.XMax, axMap1.CtlBounds.YMin, 2);
tempFea.Parts._Item(1).AddXY(axMap1.CtlBounds.XMax, axMap1.CtlBounds.YMax, 3);
tempFea.Parts._Item(1).AddXY(axMap1.CtlBounds.XMin, axMap1.CtlBounds.YMax, 4);
tempFea.Update(tempFea, new MapXLib.RowValuesClass());
}
------解决方案--------------------
这个我以前做过，给你看看我我的代码吧：
