I want to pull all the items in the drop-down menu one by one into the datagridview rows using Selenium in C#. Can you help me on this issue?

What I have tried:

I tried the following codes.

I tried the code below, but these codes pull all elements into one line.

<pre lang="C#">
List<IWebElement> selectElements = drv.FindElements(By.Id("dersler"));
foreach (IWebElement select in selectElements)
{
    var selectElement = new SelectElement(select);
    List<string> lst = new List<string>();
    lst.Add(select.Text);
    DataTable dt = new DataTable();
    DataColumn dtcol = new DataColumn(select.Text);
    dt.Columns.Add(dtcol);
    for (int i = 0; i < lst.Count; i++)
    {
       dataGridView1.DataSource = dt;
    }

}

Without seeing the html markup that you are tyring to parse, we cannot comment on the code. Remember, we can not see your screen.

As per your code snippet, there are a couple of issues that might be leading to the unexpected behavior. You're creating a DataTable within the loop, causing it to reset with each iteration. To address this, move the DataTable creation outside the loop and set the DataTable as the DataSource after the loop. Below is the updated version of your code:

C#

List<IWebElement> selectElements = drv.FindElements(By.Id("dersler"));
// Create DataTable outside the loop to avoid resetting it in each iteration
DataTable dt = new DataTable();
foreach (IWebElement select in selectElements)
{
    var selectElement = new SelectElement(select);

    // Create a new column for each dropdown
    DataColumn dtcol = new DataColumn(selectElement.Text);
    dt.Columns.Add(dtcol);

    // Create a new row for each option in the dropdown
    foreach (IWebElement option in selectElement.Options)
    {
        DataRow row = dt.NewRow();
        row[selectElement.Text] = option.Text;
        dt.Rows.Add(row);
    }
}
// Set the DataTable as the DataSource after the loop
dataGridView1.DataSource = dt;
