I want to search for student numbers in the datagridview on the web page with Selenium and click on the image link at the beginning of the number line found. But I couldn't understand the logic. Would you mind helping me, plaese?

The error you’re encountering is due to the redeclaration of dataGridView1 as a local variable, which is hiding the field Form1.dataGridView1 . To resolve this issue, you can avoid redeclaring dataGridView1 inside the method where this code is written. Instead, you can use a different variable name for the IWebElement that you’re trying to find with WebDriverWait . Here’s how you can modify your code: var val0 = dataGridView1.Rows[i].Cells[0].Value?.ToString(); //student number in the datagrdiview driver.Navigate().GoToUrl("my link"); WebDriverWait wait = new WebDriverWait(drv, TimeSpan.FromSeconds(10)); IWebElement gridElement = wait.Until(driver => driver.FindElement(By.Id(val0))); // changed variable name here IWebElement studentNumberElement = drv.FindElement(By.XPath("//td[contains(text(), 'val0')]")); IWebElement imageLink = studentNumberElement.FindElement(By.XPath("/html/body/form[2]/div[4]/div[1]/div[4]/div/div/div[2]/div/div["+(i+1)+"]/div/div[2]/h6")); imageLink.Click(); In this modified code, I’ve changed the name of the IWebElement from dataGridView1 to gridElement to avoid the conflict with the existing dataGridView1 field12. Please replace "my link" with your actual URL and adjust the XPath queries as needed. Thanks

Here’s a basic example of how you might use Selenium WebDriver in C# to search for student numbers in a datagridview and click on the image link at the beginning of the number line found. Please note that this is a simplified example and the actual code might need to be adjusted based on the structure of your webpage. using OpenQA.Selenium; using OpenQA.Selenium.Chrome; using OpenQA.Selenium.Support.UI; using System; class Program { static void Main() { // Initialize the Chrome driver IWebDriver driver = new ChromeDriver(); // Open the webpage driver.Navigate().GoToUrl("http://your-web-page-url.com"); // Wait for the page to load WebDriverWait wait = new WebDriverWait(driver, TimeSpan.FromSeconds(10)); // Find the datagridview element IWebElement datagridview = wait.Until(driver => driver.FindElement(By.Id("datagridview-id"))); // Find the student number in the datagridview IWebElement studentNumberElement = datagridview.FindElement(By.XPath("//td[contains(text(), 'student-number')]")); // Find the image link at the beginning of the number line found IWebElement imageLink = studentNumberElement.FindElement(By.XPath(".//preceding::img[1]")); // Click on the image link imageLink.Click(); // Close the driver driver.Quit(); } } In this code: Replace "http://your-web-page-url.com" with the URL of your webpage. Replace "datagridview-id" with the id of your datagridview element. Replace 'student-number' with the actual student number you’re searching for. Remember to install the Selenium WebDriver and ChromeDriver NuGet packages in your project. You can do this in Visual Studio by right-clicking on your project -> Manage NuGet Packages -> Search for Selenium.WebDriver and Selenium.Chrome.WebDriver -> Install. Also, ensure that the ChromeDriver version matches the version of Chrome installed on your machine. If they don’t match, you might encounter issues. I hope this helps! Let me know if you have any other questions. ??

Thanks Naimish for your help. I modified my codes with yours. But I am getting an errror in this line. IWebElement dataGridView1 = wait.Until(driver => driver.FindElement(By.Id(val0))); I am defining the student number like that (Hata CS0844 Ifade edilmeden önce 'dataGridView1' yerel degiskeni kullanilamiyor. Yerel degiskenin bildirimi 'Form1.dataGridView1' alanini gizler.. In English: Before being expressed, 'DatagridView1' local variable cannot be used. The notification of the local variable hides the field of 'form1.DatagridView1' field. ) var val0 = dataGridView1.Rows[i].Cells[0].Value?.ToString();//student number in the datagrdiview driver.Navigate().GoToUrl("my link") WebDriverWait wait = new WebDriverWait(drv, TimeSpan.FromSeconds(10)); IWebElement dataGridView1 = wait.Until(driver => driver.FindElement(By.Id(val0))); // this line is giving error. IWebElement studentNumberElement = drv.FindElement(By.XPath("//td[contains(text(), 'val0')]")); With this line, the primary line that is defined as the number is overlapping .. IWebElement imageLink = studentNumberElement.FindElement(By.XPath("/html/body/form[2]/div[4]/div[1]/div[4]/div/div/div[2]/div/div["+(i+1)+"]/div/div[2]/h6")); imageLink.Click();
