wpf - 无法从 DataGridTemplateColumn 获取确切的 WPF DataGrid 嵌入式控件类型

Question

public void MouseSingleClickEditable(object sender, MouseButtonEventArgs e)
{

    if ((!datagrid.HasItems) || datagrid.SelectedIndex < 0) return;

    DataGridColumn clmn = datagrid.CurrentColumn;
    if (clmn != null)
    {
        String columnType = clmn.GetType().Name;

            switch (columnType)
            {
                case "DataGridTemplateColumn":
                case "DataGridCheckBoxColumn":
                    row = (DataGridRow)datagrid.ItemContainerGenerator.ContainerFromItem(datagrid.Items[datagrid.SelectedIndex]);
                    if (!row.IsEditing)
                    {

                        datagrid.IsReadOnly = false;
                        datagrid.BeginEdit();
                    }

                    break;
                default:
                    break;
        }
    }
}

我的 WPF Datagrid 中有 2 个 DatePickers、Checkbox 和一个组合框，但是在获取列类型时，我只将它作为 DataGridTemplateColumn 而不是类型 DataGridDatePickerColumn 或 DataGridComboboxColumn。如何从 DataGridTemplateColumn 中提取确切的控件类型。

   public void MouseSingleClickEditable(object sender, MouseButtonEventArgs e) {
            var datagrid = new DataGrid();
            if ((!datagrid.HasItems) || datagrid.SelectedIndex < 0) return;

            DataGridColumn clmn = datagrid.CurrentColumn;
            if (clmn != null) {
                if (clmn is DataGridCheckBoxColumn) {
                    //do something
                } else if (clmn is DataGridTemplateColumn) {
                    var templateColumn = (DataGridTemplateColumn)clmn;

                    var rootControlOfCellTemplate = templateColumn.CellTemplate.LoadContent();
                    var rootControlOfCellEditingTemplate = templateColumn.CellEditingTemplate.LoadContent();
                    // you can now check for types of the template. CellEditingTemplate is for template in edit mode, and CellTemplate for "non-edit" mode
                    // for example
                    if (rootControlOfCellTemplate is Button) {
                        //do something
                    }
                    if (rootControlOfCellEditingTemplate is DatePicker) {
                        //do something
                    }
                }
            }
        }

请注意我如何检查类型。通常你应该这样做，而不是通过硬编码的字符串。
