Unable to fetch value of web element even though it exists

I am trying to fetch the Text of All table rows in a web page using Selenium C#. Below is the code for retriving all tr's from the web page:

  var trElements = driver.FindElements(By.TagName("tr"));

This shows the data correctly. For example, tr element number 35 has text 'canara bank' in it, that can be seen in below image.

enter image description here

Now I am trying to extract only text of all the tr elements. Either by using LINQ or by using for loop:

string[] strrr=      trElements.Select(t => t.Text).ToArray();

Surprisingly, Text property of most of the element does not show up the data that was shown in web element. Randomly data of some elements keeps showing up or goes off.

enter image description here

I want to ensure that data of web elements is correctly converted to string array. How to achieve this?

I think there are 3 possibilities.
1. The rows are not visible. So element.Text can't give you the text. In this case, you need to use element.GetAttribute("innerText") instead of element.Text.

string[] strrr = trElements.Select(t => t.GetAttribute("innerText")).ToArray();


2. The script does not have enough wait time. In this case, you just need to add wait to check text length.

var trElements = driver.FindElements(By.TagName("tr"));
List<string> strrr = new List<string>(); 
foreach (var tr in trElements)
{
    IWait<IWebElement> wait = new DefaultWait<IWebElement>(tr);
    wait.Timeout = TimeSpan.FromSeconds(10);
    try
    {
        wait.Until(element => element.Text.Trim().Length > 1);
        strrr.Add(element.Text.Trim());
    }
    catch (WebDriverTimeoutException)
    {
        strrr.Add("");
    }
}


3. The text will be displayed when you scroll down.

int SCROLL_PAUSE_TIME = 1;
int SCROLL_LENGTH = 500;
var jsExecutor = driver as IJavaScriptExecutor;
int pageHeight = Int32.Parse((string)jsExecutor.ExecuteScript("return document.body.scrollHeight"));
int scrollPosition = 0;
while (scrollPosition < pageHeight)
{
    scrollPosition = scrollPosition + SCROLL_LENGTH;
    jsExecutor.ExecuteScript("window.scrollTo(0, " + scrollPosition + ");");
    System.Threading.Thread.Sleep(SCROLL_PAUSE_TIME);
}
var trElements = driver.FindElements(By.TagName("tr"));
