ProWindow 是ArcGIS Pro SDK中用于创建自定义窗口的关键类，帮助开发者扩展ArcGIS Pro的功能和用户界面。这些窗口可以嵌入到ArcGIS Pro的主界面中，提供与核心功能的无缝集成。
创建一个窗体xml：

</Grid>
</controls:ProWindow>允许效果：
设置DataGrid表字段名称列为下拉框，DataGridTemplateColumn 设置ComboBox动态绑定。
vb.net ,定义Person1类，用于DataGrid1设置数据源类型
Imports System.Collections.ObjectModel
Public Class Person1 '用于DataGrid1设置数据源
Public Property tc_name As String
Public Property sf_cy As Boolean
Public Property zd_name As String
Public Property zd_nameID As Integer ' 用于绑定选中的 zd_name
Public Property AvailableCategories As List(Of Zd_name)
Public Sub New(tc_name As String, sf_cy As Boolean, zd_name As String, zd_nameID As Integer, AvailableCategories As List(Of Zd_name))
Me.tc_name = tc_name
Me.sf_cy = sf_cy
Me.zd_name = zd_name
Me.zd_nameID = zd_nameID
Me.AvailableCategories = AvailableCategories
End Sub
End Class定义ComboBox动态绑定类
Public Class Zd_name
Public Property zd_ID As Integer
Public Property zd_Namea As String
End Class在窗体类中
Public Class ProWindow1
Inherits ArcGIS.Desktop.Framework.Controls.ProWindow
Private people_1 As New ObservableCollection(Of Person1)()
Public Property Categories As ObservableCollection(Of Zd_name)
Public Sub New()
InitializeComponent()
DataGrid1.ItemsSource = people_1
End Sub
Dim pmap As Map
Dim dict(50) As List(Of FieldDescription)
Dim pFeatureLayer As FeatureLayer
Dim pFeature As Feature
Dim PFeatureClass As FeatureClass
Dim pFeatCursor As RowCursor
Private Async Sub Button1_Click(sender As Object, e As RoutedEventArgs) Handles Button1.Click
Dim pMapView As MapView = MapView.Active
Dim collection As ObservableCollection(Of Person1) = DirectCast(DataGrid1.ItemsSource, ObservableCollection(Of Person1))
Dim jsq As Integer = -1
If collection IsNot Nothing Then
collection.Clear() ' 直接清空集合
End If
DataGrid1.CanUserAddRows = True '将CanUserAddRows重新设置为True，这样DataGrid就会自动生成新行，我们就能在新行中输入数据了。
If pMapView Is Nothing = True Then
MsgBox("当前打开的不是激活的地图.")
Exit Sub
End If
Dim pmap As Map = pMapView.Map
Dim categories(100) As List(Of Zd_name)
Dim jsq1 As Integer = 0
For i = 0 To pmap.Layers.Count - 1
If pmap.Layers(i).GetType.Name = "FeatureLayer" Then
jsq += 1
pFeatureLayer = pmap.Layers(i)
dict(jsq) = New List(Of FieldDescription)
Await QueuedTask.Run(Sub()
dict(jsq) = pFeatureLayer.GetFieldDescriptions
End Sub)
jsq1 = 0
categories(jsq) = New List(Of Zd_name)
For Each ttsr In dict(jsq)
jsq1 += 1
categories(jsq).Add(New Zd_name() With {.zd_ID = jsq1, .zd_Namea = ttsr.Name})
Next
people_1.Add(New Person1(pmap.Layers(i).Name, False, "", 1, categories(jsq)))
End If
Next
DataGrid1.ItemsSource = people_1
End Sub
End Class运行结果：
读取DataGrid表：vb.net
Dim tc_mc As String
Dim tc_cy As Boolean
Dim zd_id As Integer = 0
Dim tc_zd As String
Dim tc_zdZ() As String
Dim zdzs As Integer
Dim tl_id As Integer = 0
For Each row As Person1 In DataGrid1.Items
tc_mc = row.tc_name ' DataGrid第一列
tc_cy = row.sf_cy ' DataGrid第二列
zd_id = row.zd_nameID ' DataGrid第三列 ：ComboBox选中的ID
tc_zd = GetCategoryNameByID(zd_id, row.AvailableCategories) 'ComboBox下拉框元素集合
next自定义函数：
Private Function GetCategoryNameByID(categoryID As Integer, categories As List(Of Zd_name)) As String
Dim category As Zd_name = categories.FirstOrDefault(Function(c) c.zd_ID = categoryID)
Return If(category IsNot Nothing, category.zd_Namea, "Unknown")
End Function
