XCeed Datagrid에서 두 번 클릭 한 행의 열을 어떻게 확인할 수 있습니까?

Question

DataTable에서 채워진 XCeed Datagrid가 있습니다. 사용자가 셀을 두 번 클릭하면 어떤 행의 어떤 열이 선택되었는지를 결정할 수 있기를 원합니다. 어떻게해야합니까?

Answer 1

음, 간결하게 질문하는 것은 요즘 처벌되는 것 같습니다. 어떤 코드도 제공하지 않습니다.

솔루션은 WPF 작성자에게 참으로 (엄청나게) 복잡합니다.

The solution for a standard WPF DataGrid can be found here.

Public Class MyXAMLWindow 

    Private Sub grdResults_MouseDoubleClick(sender As Object, e As MouseButtonEventArgs) 
     'Cast the sender parameter to the XCeed DataGridControl' 
     Dim dg As Xceed.Wpf.DataGrid.DataGridControl = sender 

     'Extract the cell information to a custom CellInfo structure.' 
     Dim info = GetCellInfo(e.OriginalSource, dg.SelectedIndex) 

     'Pass the cellinfo to the ViewModel' 
     dg.DataContext.SelectedInfo = info 
    End Sub

     Dim cellInfo = New CellInfo(Of String)

     If dep Is Nothing Then 
      Return New CellInfo(Of String) With {.ColumnIndex = -1, .RowIndex = -1, .Value = String.Empty} 
     End If 

     If TypeOf dep Is DataCell Then 
      Dim cell As DataCell = TryCast(dep, DataCell) 

      cellInfo.ColumnIndex = cell.ParentColumn.Index 
      cellInfo.RowIndex = rowIndex 
      cellInfo.Value = cell.Content 

     End If 

     Return cellInfo 
    End Function 
End Class 

'A custom Structure to hold the data of the selected Cell.' 
Public Structure CellInfo(Of TValue) 
    Public RowIndex As Integer 
    Public ColumnIndex As Integer 
    Public Value As TValue 
End Structure

먼저 재.

private void OnDataCellMouseDoubleClick(object sender, MouseButtonEventArgs e) 
{ 
    var clickedCell = sender as DataCell; 
    var row = clickedCell.ParentRow; 
    var rowNum = row.TabIndex; 
    var column = clickedCell.ParentColumn; 
    var columnNum = column.Index; 
}
