Automation testing Selenium with c#

Question

I am able to go till Parent folder and after on Click Childs will display.

how to write method to get dispalyed child (ON CLICK).

I tried this,

public void TAB1SELECT() { 
   Actions action = new Actions(_driver);
   action.MoveToElement(_driver.FindElement(By.XPath("//[@id='dijit__TreeNode_14']/div[1]/span[3]/span[1] "))).Build().Perform(); 
   var element = (new OpenQA.Selenium.Support.UI.WebDriverWait(_driver, TimeSpan.FromSeconds(30))).Until(SeleniumExtras.WaitHelpers.ExpectedConditions.PresenceOfAllElementsLocatedBy(By.Id("dijit__TreeNode_36_label"))); 
   element[-1].Click(); 
  } 
} 

Answer 1

As you intend to click so instead of PresenceOfAllElementsLocatedBy you need to use VisibilityOfAllElementsLocatedBy(By). Additionally, instead of using index as -1 you need to use the index 0 for the first element and so on. So your effective code block will be:

public void TAB1SELECT() { 
   new Actions(_driver).MoveToElement(_driver.FindElement(By.XPath("//[@id='dijit__TreeNode_14']/div[1]/span[3]/span[1] "))).Build().Perform(); 
   var element = (new OpenQA.Selenium.Support.UI.WebDriverWait(_driver, TimeSpan.FromSeconds(30))).Until(SeleniumExtras.WaitHelpers.ExpectedConditions.VisibilityOfAllElementsLocatedBy(By.Id("dijit__TreeNode_36_label"))); 
   element[0].Click(); 
  } 
}
