ShowingEditor事件对我来说就是控制单元格的编辑属性,在特定场景中(TreeList中要求子节点某些列可编辑,父节点不可编辑)就需要使用此事件来实现,与此同时,上一篇也介绍了特定场景单元格样式改变:CustomDrawCell
举个ShowingEitor的使用,
private void treeList1_ShowingEditor(object sender, System.ComponentModel.CancelEventArgs e)
{
TreeList currentTreeList = sender as TreeList;
T row = treeList1.GetDataRecordByNode(currentTreeList.FocusedNode) as T;
if (currentTreeList != null && row !=null )
{
TreeListColumn column = currentTreeList.FocusedColumn;
if (column.FieldName == "Qty" || column.FieldName == "Price" || column.FieldName == "Content" || column.FieldName == "Remark" || column.FieldName == "Amount")
{
e.Cancel = (条件)?true:false;
}
}
}
