I am new to selenium coding, and I have the below code where I am fetching values from the table it has multiple pages, for 1st time, it reads all values from the table and control move to the next page, I m getting the error stale element reference: element is not attached to the page document but when i m debugging the code, i m not getting any error for the below code, when i run it throws an error and it shows an error at line where I have defined tdCollection

Please guide me on this.

    var ReportCount = Convert.ToInt32(_driver.FindElement(By.Id("Reporter_TotalPages")).Text);

            for (int i = 0; i < ReportCount; i  )
            {
                IList<IWebElement> _records = (IList<IWebElement>)_driver.FindElements(By.XPath("//*[contains(@id,'ReportViewerControl')]//div//table//tbody//tr[position()>2]"));
                IList<IWebElement> tdCollection;
              
                for (int j = 0; j < _records.Count; j  )
                {
                   
                   tdCollection = _records[j].FindElements(By.TagName("td"));
                    
                    var Patientdemolist = new XPatientDemographicsList();
                    {
                        Patientdemolist.PatientID = tdCollection[0].Text;
                        Patientdemolist.LastName = tdCollection[1].Text;
                        Patientdemolist.FirstName = tdCollection[2].Text; 

                    };
                    PatientDemographicsList.Add(Patientdemolist);
                    tdCollection = null;
                }
                if (ReportCount - 1 > i)
                {
                    // For Next Page
                    _driver.FindElement(By.Id("Report_Next")).Click();
                } 
            }

Try adjusting your conditional to this.

 if (ReportCount - 1 > i)
{
    // For Next Page
    _driver.FindElement(By.Id("Report_Next")).Click();
    Thread.Sleep(5000)
} 

Its possible you are getting a reference before the page has completed loading from the .Click() method. If that works you can refine the tests to wait implictly/ use fluent waits instead of waiting for 5 seconds. https://www.selenium.dev/documentation/webdriver/waits/

yes I tried this one and also I tried the below loop for both _records and tdcollection but still facing the same error

 do
{
_driver.Manage().Timeouts().PageLoad.Add(System.TimeSpan.FromSeconds(30));
tdCollection = _records[j].FindElements(By.TagName("td"));
}
while (tdCollection.Count <= 0);
