Handle with tables in selenium C#

Question

I a trying to handle with tables in selenium C#. I have a table which has a few rows and a few columns. Each row has column with name and buttons. I want to click "Open" button, where the name in the row is, for example "Name1". But i can't find even the td's in the table. Here's what i was trying to do:

public void SelectNameAndClick(string name)
        {
            IWebElement tableElement = driver.FindElement(By.XPath("//table[@id='TableMp']"));
            IList<IWebElement> tableRow = tableElement.FindElements(By.TagName("tr"));
            IList<IWebElement> rowTD;
            foreach (IWebElement row in tableRow)
            {
                if (row.Text.Equals(name));
                rowTD = row.FindElements(By.TagName("td"));

I attached screen shot of the table: here

<table class="table table-condensed table-hover" id="TableMp" style="" data-bind="visible: opAGents().length > 0">
                
                    <tbody data-bind="foreach: opAGents">
                        <tr>
                            <td>
                                <span  agentid="OPAgents/4b2f885101f740fdb72c5874596577ac" data-original-title="4b2f885101f740fdb72c5874596577ac">4b2f885101f740fdb72c5874596577ac</span>
                            </td>
                            <td class="vert-align">

Answer 1

This should work for you:

public void SelectNameAndClick(string name)
{
    // Selecting your table element.
    IWebElement table = driver.FindElement(By.XPath("//table[@id='TableMp']"));

    // Select the row where name of the agent equals to the name we're searching for.
    IWebElement row = table
                .FindElements(By.TagName("tr"))
                .FirstOrDefault(element =>
                    element.FindElements(
                        By.XPath($"//span[@agentid and text()='{name}']")).Count > 0);

    // If there is no such row, do nothing.
    if (row == null)
        return;

    // Find the button with the 'Open' text somewhere within it and click the button.
    IWebElement button = row.FindElement(By.XPath("//button//*[text()='Open']"));
    button.Click();
}
