与UI自动化和.NET Datagrid的内容 [英] Datagrid contents with UI Automation and .net

问题描述

我有一些麻烦，使用UI自动化，并可以使用一些指针读取DataGrid的内容在外部应用程序。这是我到目前为止有：

I'm having some trouble reading the contents of a Datagrid in an external application using UI Automation and could use some pointers. Here's what I have so far:

int id = System.Diagnostics.Process.GetProcessesByName("Book")[0].Id;
AutomationElement desktop = AutomationElement.RootElement;

AutomationElement bw = desktop.FindFirst(TreeScope.Children, new PropertyCondition(AutomationElement.ProcessIdProperty, id));

AutomationElement datagrid = bw.FindFirst(TreeScope.Children, new PropertyCondition(AutomationElement.AutomationIdProperty, "lv"));

AutomationElementCollection lines = datagrid.FindAll(TreeScope.Children, new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.DataItem));

AutomationElementCollection items = lines[1].FindAll(TreeScope.Children, new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Custom));

GridItemPattern pattern = items[1].GetCurrentPattern(GridItemPattern.Pattern) as GridItemPattern;
TableItemPattern tablePattern = items[1].GetCurrentPattern(TableItemPattern.Pattern) as TableItemPattern;

这工作在尽可能我可以访问从GridItemPattern和TableItemPattern列ID和行ID但我怎么访问是在特定的单元格的值？它甚至有可能？

This works in as much as I can access the column ids and row ids from the GridItemPattern and TableItemPattern but how do I access the value that is in that specific cell? Is it even possible?

感谢。

推荐答案

我终于想通了这一点，它需要使用CacheRequest的要求上的AutomationElement Name属性。这里是最后的code：

I finally figured this out, it requires the use of CacheRequest to request the Name property on the AutomationElement. Here's the final code:

var cacheRequest = new CacheRequest 
                { 
                    AutomationElementMode = AutomationElementMode.None,
                    TreeFilter = Automation.RawViewCondition
                };

                cacheRequest.Add(AutomationElement.NameProperty);
                cacheRequest.Add(AutomationElement.AutomationIdProperty);

                cacheRequest.Push();

                var targetText = loginLinesDetails[i].FindFirst(TreeScope.Children, new PropertyCondition(AutomationElement.ClassNameProperty, "TextBlock"));

                cacheRequest.Pop();

                var myString = targetText.Cached.Name;
