使用UI Automation选择一行数据网格 [英] Select a row of datagrid using UI Automation

问题描述

我正在编写UI自动化软件。我需要在datagrid中选择一行，然后单击运行按钮。我尝试了互联网上的大多数示例代码，但它们对我不起作用。例如，选择gridview行：



当我编写以下代码时：

Hi,
I'm writing a UI automation software. I need to select a row in the datagrid and then click on the run button. I tried most of the example codes in the internet and they didn't work for me. For example for selecting a gridview row:

When I write the following code:

AutomationElement dataGrid = this.mainWindow.FindFirst(TreeScope.Children, new PropertyCondition(AutomationElement.AutomationIdProperty, "2885"));

if (dataGrid != null) {

GridPattern pattern = GetGridPattern(dataGrid);
AutomationElement tempElement = pattern.GetItem(1, 1);
tempElement.SetFocus();
}

我收到错误：目标元素无法获得焦点。这与最后一行有关。



我也尝试过代码：

I receive the error: "Target element cannot receive focus." which is related to the last line.

I also tried the code:

AutomationElement mainGrid = // find the grid in the window var columnCount = (int)mainGrid.GetCurrentPropertyValue(GridPattern.ColumnCountProperty);

var mainGridPattern = (GridPattern)mainGrid.GetCurrentPattern(GridPattern.Pattern);

var rowToSelect = 2;

// select just the first cell var item = mainGridPattern.GetItem(rowToSelect, 0);

var itemPattern = (SelectionItemPattern)item.GetCurrentPattern(SelectionItemPattern.Pattern);

itemPattern.Select();

但我和我收到错误：不支持的模式。



我应该提一下，我正在使用UI Spy来检索元素属性。



你能不能解释我出了什么问题，我应该如何选择一行？

but I and I received the error :"Unsupported Pattern".

I should mention that I'm using UI Spy for retrieving the elements properties.

Could you explain me what's wrong and how should I select a row?

推荐答案

过了一会儿，但看看这个就是

Been a while, but check this out

Quote：

GridPattern不支持对网格的主动操作;此功能需要TransformPattern控件模式。

GridPattern does not support active manipulation of a grid; the TransformPattern control pattern is required for this functionality.
