Selenium Webdriver, C# and accessing rows in a table

Question

There's been other questions like these, but I feel like I'm missing some of the basics, so I'll try asking a potential duplicate question:

How do I get/list the contents of each row in a table like this?

<div class="entity-body list-entity-body entity-content-payload">
   <div class="table-holder l-height-full" style="overflow-y: scroll; flex: 1 1 auto" data-bind="fullHeight: 'leave-space-for-following-elements'">
      <content-placeholder class="l-height-full jsx-component-rendered" content-id="list-page-list">
         <content-placeholder class=" jsx-component-rendered" content-id="standard-list-page-list">
            <section class=" jsx-component-rendered" data-bind="component: { name: listCustomElementName, params: listParams }">
               <table class="table-default" cellspacing="0" style="width: 100%">
                  <thead>
                     <tr>
                        ...
                     </tr>
                  </thead>
                  <tbody>
                     <tr data-bind="css: { selected: $parent.selected.indexOf(href) != -1 }, loadRelated: $parent.fieldsFromRelated">>
                        <td class="fit-cell-content">
                           <a data-bind="clientHref: href" href="#/Customers/149999/Locations/000" data-server-href="/Api/Customers/149999/Locations/000">
                        </td>
                        <td class="keyColumn fit-cell-content">
                           <a data-bind="clientHref: href" href="#/Customers/149999/Locations/000" data-server-href="/Api/Customers/149999/Locations/000">
                        </td>
                        <td class="keyColumn fit-cell-content">
                           <a data-bind="clientHref: href" href="#/Customers/149999/Locations/000" data-server-href="/Api/Customers/149999/Locations/000">
                        </td>
                        <td class="keyColumn fit-cell-content">
                           <a data-bind="clientHref: href" href="#/Customers/149999/Locations/000" data-server-href="/Api/Customers/149999/Locations/000">
                        </td>
                        <td class="keyColumn fit-cell-content">
                           <a data-bind="clientHref: href" href="#/Customers/149999/Locations/000" data-server-href="/Api/Customers/149999/Locations/000">
                        </td>
                        <td class="fit-cell-content">
                           <a data-bind="clientHref: href" href="#/Customers/149999/Locations/000" data-server-href="/Api/Customers/149999/Locations/000">
                        </td>
                     </tr>   

There are other things on the page, and this code is nested quite a but down in the tags, but it should be possible. However, one thing is finding the rows and contens (which I need hints for doing) - another is storing it and using it.

UPDATE: kirbycope has a great answer below. Building on that, how do check each row for a specific name and then click it?

UPDATE2: Using kirbycope's examples below, here's what I've got so far:

(I search the table for an row containing a specific text - "Bergen" in a td)

var table = GCDriver.Instance.FindElement(By.TagName("table"));
var rows = table.FindElements(By.TagName("tr"));

foreach (var row in rows) {
    if (row.Text.Contains("Bergen")) {
    //Console.WriteLine(row.Text);

    var tds = row.FindElements(By.TagName("a"));
    foreach (var entry in tds) {
        Console.WriteLine(entry.Text);
        entry.Click();
    }
}

The Console.WriteLine line works fine, printing this:

149999-002
Bergen
0
0
13
Branch Office

However, the entry.Click() line does not, resulting in this error:

OpenQA.Selenium.StaleElementReferenceException: stale element reference:     
element is not attached to the page document
  (Session info: chrome=56.0.2924.87)
  (Driver info: chromedriver=2.28.455520     
(cc17746adff54984afff480136733114c6b3704b),platform=Windows NT 10.0.14393 x86_64)

Most of what I can find on that exception is that people seem to think it's because an element is not loaded, not accessible etc. on the web page, and to implement a wait or similar. But this is not the case here; I can add a timeout of 10 hours and the exception is still there. Also, if I just use the XPath of a specific row and add .Click() to that, it works fine.

UPDATE 3: As per ChatuD's help below, I'm trying this to get all the elements of a specific row (tr):

var rows = table.FindElements(By.TagName("tr"));
    foreach (var row in rows) {
        if (row.Text.Contains("Bergen")) {
            IList<IWebElement> List = row.FindElements(By.TagName("a"));
            List<String> NewList = new List<String>();

            foreach (var item in List) {
                NewList.Add(item.Text);
            }

            Actions action3 = new Actions(GCDriver.Instance);
            action3.MoveToElement(NewList[<Index number >]).Perform();
        }

But - and pardon my lack of both C# and VS knowledge - how do I access the row element in NewList in the last line above? It doesn't work just typing the index number, and "ElementAt" doesn't exist as a method.

Answer 1

Get the table, then its rows, then each row's TDs, then each TD's anchor:

var table = driver.FindElement(By.TagName("table"));
var rows = table.FindElements(By.TagName("tr"));
foreach (var row in rows)
{
     var rowTds = row.FindElements(By.TagName("td"));
     foreach (var td in rowTds)
     {
         var a = td.FindElement(By.TagName("a"));
         Console.WriteLine("HREF: " + a.GetAttribute("href"));
     }
}

Or, if you just want each of the TDs anchors you could:

var tds = driver.FindElements(By.TagName("td"));
foreach (var td in tds)
{
    var a = td.FindElement(By.TagName("a"));
    var href = a.GetAttribute("href"));
    if(href.Contains("Customer1234"))
    {
        a.Click();
        break;
    }
}

The takeaway here is that *.FindElements() returns a collection of elements that you can parse. In much the same way as document.querySelectorAll() does in JavaScript.

Answer 2

As every line start with a '<a' tag

IList<IWebElement> List = driver.FindElements(By.TagName("a"));
List<String> NewList = new List<String>();
foreach (var item in List)
            {
                NewList.Add(item.Text);
            }

The you will get all the list of items in the table as NewList.

So for clicking on an element dont directly use NewList[<Index number>]. Use Actions.

Actions action3 = new Actions(Setup.driver);
            action3.MoveToElement(NewList[<Index number>]).Perform();

            Thread.Sleep(4000);
            action3.Click(NewList[<Index number>]).Perform();
