来源：互联网发布：仪器比对数据分析编辑：程序博客网时间：2024/04/28 15:41

目的：
1.arcgis server9.2 ADF实现EditorTask功能扩展。在EditorTask控件上添加地理元素框选裁剪和选中元素数量统计功能。
准备工作：
1.参考DeveloperKit/SamplesNET/Server/Web_Applications目录下的Common_CustomEditorTaskCSharp.zip。
2.本例是在ArcGIS.Server.9.2.DotNet实现在线编辑EditorTask使用（自带例子十、二）基础上做的。
完成后的效果图：

开始：
1.在上一篇中已经实现了EditorTask控件的使用，已经编辑属性的过滤控制等功能，本篇在上一篇的基础上实现 EditorTask功能扩展，在Editor面板上添加一个框选裁剪和选中数量统计功能两个自定义功能。
2.首先在Page_Init页面事件中添加EditorTask1的ToolsCreated事件，代码如下：

protected void Page_Init(object sender, EventArgs e)
2

{
3

//ToolsCreated事件
4

EditorTask1.ToolsCreated += new ESRI.ArcGIS.ADF.ArcGISServer.Editor.Tools.ToolsCreatedEventHandler(EditorTask1_ToolsCreated);
5

}

3.在EditorTask1_ToolsCreated方法中实现框选裁剪和数量统计2个功能按钮的添加，具体代码和说明如下：

void EditorTask1_ToolsCreated(object sender, ESRI.ArcGIS.ADF.ArcGISServer.Editor.Tools.ToolsCreatedEventArgs e)
2

{
3

//编辑panel
4

if (e.Parent == EditorTask1.Editor.ExistingFeatureEditor)
5

{
6

//编辑panel包含两个toolbars: GeometryToolbar1和GeometryToolbar2
7

foreach (ESRI.ArcGIS.ADF.ArcGISServer.Editor.Tools.EditorToolbar editorToolbar in e.Toolbars)
8

{
9

string ToolbarID=editorToolbar.ID;
10

if (ToolbarID == "GeometryToolbar1")
11

{
12

//name,mapID,useSnapping,geometryType,minSelectedFeatures
13

//EditorTool的名称，ID，是否扑捉，元素类型，最小选择数
14

ESRI.ArcGIS.ADF.ArcGISServer.Editor.Tools.EditorTool clip =new ESRI.ArcGIS.ADF.ArcGISServer.Editor.Tools.EditorTool("Clip",((ESRI.ArcGIS.ADF.ArcGISServer.Editor.EditExistingFeaturePanel)e.Parent).ParentEditor.MapID, false,ESRI.ArcGIS.ADF.ArcGISServer.Editor.Tools.ToolGeometry.Line | ESRI.ArcGIS.ADF.ArcGISServer.Editor.Tools.ToolGeometry.Polygon, 1);
15

//EditorTool的客户端Action,设置设置成矩形操作
16

clip.ClientAction = ESRI.ArcGIS.ADF.Web.UI.WebControls.Constants.HTML_DRAG_RECTANGLE;
17

//设置EditorTool的图片和tip
18

clip.DefaultImage = "~/images/clip.png";
19

clip.SelectedImage = "~/images/clip_ON.png";
20

clip.HoverImage = "~/images/clip_OVER.png";
21

clip.ToolTip = "Clip feature(s)";
22

//设置EditorTool的功能类
24

clip.ServerActionAssembly = "CustomEditorTask";
25

clip.ServerActionClass = "CustomEditorTask.ClipFeatures";
26

//把这个EditorTool添加到Toolbar上
27

editorToolbar.ToolbarItems.Add(clip);
28

//设置宽
29

editorToolbar.Width = new Unit(editorToolbar.Width.Value + 35, UnitType.Pixel);
30

}
31

}
32

//新建EditorToolbar
34

ESRI.ArcGIS.ADF.ArcGISServer.Editor.Tools.EditorToolbar newEditorToolbar =new ESRI.ArcGIS.ADF.ArcGISServer.Editor.Tools.EditorToolbar();
35

//只显示图标
36

newEditorToolbar.ToolbarStyle = ESRI.ArcGIS.ADF.Web.UI.WebControls.ToolbarStyle.ImageOnly;
37

//id
38

newEditorToolbar.ID = "MyCustomToolbar";
39

//
40

newEditorToolbar.BuddyControlType = ESRI.ArcGIS.ADF.Web.UI.WebControls.BuddyControlType.Map;
41

//设置EditorToolbar的Map控件
42

newEditorToolbar.BuddyControls.Add(new ESRI.ArcGIS.ADF.Web.UI.WebControls.BuddyControl(((ESRI.ArcGIS.ADF.ArcGISServer.Editor.EditExistingFeaturePanel)e.Parent).ParentEditor.MapID));
43

//新建EditorCommand
45

ESRI.ArcGIS.ADF.ArcGISServer.Editor.Tools.EditorCommand vertCount =new ESRI.ArcGIS.ADF.ArcGISServer.Editor.Tools.EditorCommand("VerticeCount", ESRI.ArcGIS.ADF.ArcGISServer.Editor.Tools.ToolGeometry.All, 1);
46

//设置EditorCommand的图片和tip
47

vertCount.DefaultImage = "~/images/verticecount.png";
48

vertCount.SelectedImage = "~/images/verticecount_ON.png";
49

vertCount.HoverImage = "~/images/verticecount_OVER.png";
50

vertCount.ToolTip = "Count the number of vertices in the selected feature";
51

//设置EditorCommand的功能类
52

vertCount.ServerActionAssembly = "CustomEditorTask";
53

vertCount.ServerActionClass = "CustomEditorTask.VerticeCount";
54

//把新建EditorCommand添加到EditorToolbar
56

newEditorToolbar.ToolbarItems.Add(vertCount);
57

newEditorToolbar.Width = new Unit(newEditorToolbar.ToolbarItems.Count * 35, UnitType.Pixel);
58

//把新建的EditorToolbar添加到EditorTask1
60

e.Toolbars.Add(newEditorToolbar);
61

}

4.上面把2个功能按钮添加到Editor面板上后还需要编写实现具体功能的代码，就上面代码中clip.ServerActionClass = "CustomEditorTask.ClipFeatures";和vertCount.ServerActionClass = "CustomEditorTask.VerticeCount";的ClipFeatures类和VerticeCount类，新建CustomEditorTools.cs文件，然后添加如下代码：

namespace CustomEditorTask
2

{
3

class ClipFeatures : EditorServerToolAction
4

{
5

private List<int> features = new List<int>();
6

public List<int> Features
8

{
9

get { return features; }
10

}
11

protected override bool Init(Editor editor)
13

{
14

features.Clear();
15

return base.Init(editor);
16

}
17

protected override void EditorServerAction()
19

{
20

//区域
21

IEnvelope env = Geometry as IEnvelope;
22

//map描述
23

MapDescription mapDesc = Editor.MapFunctionality.MapDescription;
24

//选中的Feature数量
25

int[] fidSet = LayerDescription.SelectionFeatures;
26

if (fidSet != null && fidSet.Length > 0)
27

{
28

//geometry拓扑逻辑操作
29

ITopologicalOperator3 topo3 = null;
30

IFeature feature = null;
31

try
32

{
33

//开始编辑
34

StartEditOperation();
35

//IFeatureCursor提供枚举features集合的成员方法，游标
36

IFeatureCursor cursor = FeatureLayer.FeatureClass.GetFeatures(fidSet, false);
37

//获取下一个features
38

feature = cursor.NextFeature();
39

//进行循环
40

while (feature != null)
41

{
42

topo3 = (ITopologicalOperator3)feature.ShapeCopy;
43

topo3.Clip(env);
44

IGeometry geometry = (IGeometry)topo3;
45

if (!geometry.IsEmpty)
46

{
47

feature.Shape = geometry;
48

//存储Feature，存储row
49

feature.Store();
50

features.Add(feature.OID);
52

}
53

feature = cursor.NextFeature();
54

}
55

//停止编辑
56

StopEditOperation();
57

}
58

catch (Exception e)
59

{
60

//终止编辑操作
61

AbortEditOperation(e);
62

}
63

if (features.Count > 0)
64

{
65

// Refresh the Editor, Map, vertices, etc. with the new selection set
66

Refresh(features, true);
67

}
68

}
69

}
70

}
71

class VerticeCount : EditorServerCommandAction
73

{
74

protected override void EditorServerAction()
75

{
76

ESRI.ArcGIS.ADF.ArcGISServer.MapDescription mapDesc = Editor.MapFunctionality.MapDescription;
77

int[] fidSet = LayerDescription.SelectionFeatures;
78

if (fidSet != null && fidSet.Length > 0)
79

{
80

IFeature feature = null;
81

int pointCount = 0;
83

//IFeatureCursor提供枚举features集合的成员方法，游标
84

IFeatureCursor cursor = FeatureLayer.FeatureClass.GetFeatures(fidSet, false);
85

feature = cursor.NextFeature();
86

while (feature != null)
87

{
88

//如果是点类型
89

if (feature.Shape is IPoint)
90

{
91

pointCount += 1;
92

}
93

else//非点类型
94

{
95

IPointCollection pointCollection = (IPointCollection)feature.Shape;
96

pointCount += pointCollection.PointCount;
97

}
98

feature = cursor.NextFeature();
99

}
100

string status = string.Format("alert( '选中数量为：{0}个');", pointCount);
101

ESRI.ArcGIS.ADF.Web.UI.WebControls.CallbackResult jsStatusCallbackResult =new ESRI.ArcGIS.ADF.Web.UI.WebControls.CallbackResult(null, null, "javascript", status);
102

this.ToolbarItemInfo.Toolbar.CallbackResults.Add(jsStatusCallbackResult);
103

}
104

}
105

}
106

107

public class CustomEditorTools
108

{
109

110

}
111

}
112

5.这样就完成了2个自定义功能的开发，测试运行。
6.这里例子中还有一个自定义 TooledEditorPanel的实现了，觉得不是太有用了这里就不详细讲了贴一下代码和说明。

namespace CustomEditorTask
2

{
3

public class CustomCreateFeaturePanel : TooledEditorPanel
4

{
5

public CustomCreateFeaturePanel(EditorTask task): base("Custom Create Feature Panel", task, "customCreateFeaturePanel")
6

{ }
7

protected override void OnLoad(EventArgs e)
9

{
10

base.OnLoad(e);
11

//ParentEditor的Layer变换事件
12

this.ParentEditor.LayerChanged += new ESRI.ArcGIS.ADF.ArcGISServer.Editor.Editor.LayerChangedHandler(Editor_LayerChanged);
13

}
14

//当选择图层的类型变换时间显示相应的编辑工具
16

void Editor_LayerChanged(ESRI.ArcGIS.Carto.IFeatureLayer featureLayer)
17

{
18

//获取EditorToolbar
19

ESRI.ArcGIS.ADF.ArcGISServer.Editor.Tools.EditorToolbar toolbar =(ESRI.ArcGIS.ADF.ArcGISServer.Editor.Tools.EditorToolbar)this.Toolbars[0];
20

//获取EditorTool
21

ESRI.ArcGIS.ADF.ArcGISServer.Editor.Tools.EditorTool tool =(ESRI.ArcGIS.ADF.ArcGISServer.Editor.Tools.EditorTool)toolbar.ToolbarItems[0];
22

//设置FeatureTool属性
23

SetCreateFeatureToolProperties(featureLayer, ref tool);
24

//刷新EditorToolbar
25

toolbar.Refresh();
26

//进行回调登记
27

ParentEditor.CallbackResults.CopyFrom(toolbar.CallbackResults);
28

//设置tool的属性js
30

string jsToolbarItemEnable = "var toolbar = Toolbars['" + toolbar.ClientID + "']; var toolbaritem = toolbar.items['" + tool.Name + "'];toolbaritem.clientAction = 'Map" + tool.ClientAction + "'; toolbaritem.defaultImage = '" + tool.DefaultImage + "'; toolbaritem.hoverImage = '" + tool.HoverImage + "';toolbaritem.selectedImage = '" + tool.SelectedImage + "';toolbaritem.disabledImage = '" + tool.DisabledImage + "';EditorToolbars['" + toolbar.ClientID + "'].tools['" + tool.Name + "'].shapeType = '" + tool.GeometryType.ToString() + "';";
31

//CallbackResult就可以将信息传回客户端，执行js脚本
32

ESRI.ArcGIS.ADF.Web.UI.WebControls.CallbackResult setToolPropertiesCallbackResult =new ESRI.ArcGIS.ADF.Web.UI.WebControls.CallbackResult(null, null, "javascript", jsToolbarItemEnable);
33

ParentEditor.CallbackResults.Add(setToolPropertiesCallbackResult);
34

}
