根據另一個datagridview中的選定行填充datagridview

Question

我有兩個datagrid gridproperty和gridpropertyselection。有一個包含數據的表格。我必須在dataGridviw中填充數據，該數據名爲gridpropertyselection accor to gridProperty datagrid中的選定行。

我想知道哪些事件將用於此目的。我介紹下面的代碼。但在Dim index中出現錯誤As Integer = gridProperty.CurrentRow.Index this line

Private Sub gridProperty_SelectionChanged(ByVal Sender As Object, ByVal e As System.Windows.Forms.DataGridViewRowStateChangedEventArgs) Handles gridProperty.RowStateChanged 


    Dim dtPropertySelection As DataTable = m_ds.Tables(0) 

    Dim i As Integer 
    Dim count As Integer = gridPropertySelection.Rows.Count 
    ' If (gridProperty.CurrentRow.IsNewRow IsNot Nothing) Then 
    Dim index As Integer = gridProperty.CurrentRow.Index 
    Dim PropertyID As Integer = gridProperty.Rows(index).Cells("PropertyID").Value 
    While i < dtPropertySelection.Rows.Count 
     If PropertyID = dtPropertySelection.Rows(i).Item("PropertyID") Then 
      gridPropertySelection.Rows.Add() 
      gridPropertySelection.Rows(count).Cells("colSelectionDescription").Value() = dtPropertySelection.Rows(i).Item("SelectionDescription") 
      gridPropertySelection.Rows(count).Cells("colAssociatedText").Value() = dtPropertySelection.Rows(i).Item("AssociatedText") 
      count = count + 1 
     End If 
     i = i + 1 
    End While

您可以使用datagridview的CellClick事件。
另外，儘量使用
Dim index As Integer = gridProperty.CurrentCell.RowIndex()
