tabControll的Map页面中(mapViewl),将MapLayout控件添加到tabControll的Layout页面中(mapLayoutl),控件的Dock属性设置为Fill。为了将这三个控件相互关联起来，首先要给layersLegendl添加一个MapFrame,点击layersLegendl属性中的MapFrames属性，在弹出的对话框中增加一个MapFrame：&MoteIn：oDeE。"fileEditViewProjeclBuildDebugDateToolsWindowHelp••J―,」Gd09・►T[.11二：-:l二73..：*/|「空&MoteIn：oDeE。"fileEditViewProjeclBuildDebugDateToolsWindowHelp••J―,」Gd09・►T[.11二：-:l二73..：*/|「空*A,•力：七・二』L•.一」IW,Mapview▼1哥于23%田J，XrodbqxfrmMain.es[Design]。StartPageProperties▼，layenLegendlMetecInfoC.Legend.LayersLegerdMeteolnfoDemoMap"rameCollectonEditorAutoSaollMtnSzeAutoStzeMembers:MQtooInfoC.Lfigood-MapfnamoMapFrameNameNeiVMapFrame0Grid0f3v*6ridlabdTrueDra**GridlineFlic*DrasvCridTickLineFalreBGridFontArial,£ptGrtdLineColor■BlackGridLineSixe1GridLineStyteDashGridXDeit10GridXOrigin0GridYDeh10GridVOrigin0□MiteActiveFalxChockedTrue国21一OK[CanedAutoSireModeGrowOnlyAutoValidateEndblePreventFocusChencBackColor口WhiUBackgrcurdlmoge(none)BackgroundlmAgeLAyouTileBordefStyleNoneCau&MValidationTrueContextMenuStrip(none)CurrentMapFremeObjectreferencenotSGtCursorDefaultDoricFillEnabledTrueBFomArial.8PtForeColor■BhckGenerateMemberTrueIrneModeNoControlhLayoutViewFalseBLocation0,0LockedFalseMapFrame^(Collection)MaplAyout(none)EMargin山MaximuntSixe0.03MinimumStze0.0ModifiersPrivateBPadding0.0,0,0・FakeMeieoInfoC.LegerdAlapFramepropenjw:将刚添加的MapFrame的MapView属性设置为mapViewl,Active属性设置为True：将layersLegendl的MapLayout属性设置为mapLayoutl：

3、实现MapView和MapLayout切换：在tabControll_SelectedlndexChanged事件中添加如下代码：privatevoidtabControll_SelectedlndexChanged(objectsender,EventArgse)(if(tabControll.Selectedlndex==1)//MapLayout{layersLegendl.lsLayoutView=true;mapLayoutl.PaintGraphics();mapLayoutl.Refresh();)elseif(tabControll.Selectedlndex==0)//MapviewlayersLegendl.lsLayoutView=false;

mapViewl.lsLayoutMap=false;mapViewl.ZoomToExtent(mapViewl.ViewExtent);4、添加图层：在工具栏中加一个添加图层按钮，并在其Click事件中添加如下代码:privatevoidTSB_AddLayer_Click(objectsender,EventArgse)OpenFileDialogaDlg=newOpenFileDialog();"Supported(*.shp)|*.shp|WMPaDIg.Filter"Supported(*.shp)|*.shp|WMPFormats1*.shp;*.wmp;*.bln;*.bmp;*.gif;*.jpg;*.tif;*.png|ShapeFileFile(*.wmp)|*.wmp|BLNFile(*.bln)|*.bln|"+"BitmapImage(*.bmp)|*.bmp|GifImage(*.gif)|*.gif|JpegImage(*JPg)l*JPg|TifImage(*.tif)|*.tif|Pnglamge(*.png)|*.png|AllFiles(*.*)1*.*";if(aDlg.ShowDialog()==DialogResult.OK){stringaFile=aDIg.FileName;MapLayeraLayer=MapDataManage.OpenLayer(aFile);layer
