How to send numerical values to an input tag using Selenium C#

Question

I know this might be a repeated question but I tried various methods to solve this one but couldn't solve the situation

HTML code copied from the website

<input name="ctl00$TabContainer1$tpMain$ContentPlaceHolder1$Ins$txtDob" type="text" value="(dd/mm/yyyy)" maxlength="10" id="ctl00_TabContainer1_tpMain_ContentPlaceHolder1_Ins_txtDob" onselect="javascript:if(this.value=='(dd/mm/yyyy)') this.value='';this.style.color='';" onblur="javascript:InputValidation(this,'Date','Date of Birth','(dd/mm/yyyy)');" onclick="javascript:if(this.value=='(dd/mm/yyyy)') this.value='';this.style.color='';" onkeydown="return autodate(this)" onchange="javascript:CheckChanges();" onkeypress="return onlyNumbersWithForwardslash();" style="width:90%;" tabindex="0">

My code goes like this

string dob = startDate.ToString("dd/MM/yyyy", CultureInfo.InvariantCulture);
string[] array = dob.Split(new string[] { "/" }, StringSplitOptions.RemoveEmptyEntries);
char[] Chararray = string.Join(string.Empty, array).ToCharArray();

IWebElement DobElement = driver.FindElement(By.XPath("//*[@id='ctl00_TabContainer1_tpMain_ContentPlaceHolder1_Ins_txtDob']")); // .Id("ctl00_TabContainer1_tpMain_ContentPlaceHolder1_Ins_txtDob"));
    DobElement.Clear();

    foreach (char s in Chararray)
    {
         int num = Int32.Parse(s.ToString());
         DobElement.SendKeys(""+num);
    }

anyone help is appreciated to input numerical numbers to the textbox

You need to update the question with text based HTML instead of a picture. — undetected Selenium

As the desired element is a JavaScript enabled element, so to send a chracter sequence within the <input> field you need to induce WebDriverWait for the desired element to be clickable and you can use either of the following solutions:

CssSelector:

IWebElement DobElement = driver.FindElement(By.CssSelector("input[id$='_Ins_txtDob'][name$='txtDob'][onblur*='InputValidation')]"));
DobElement.Click();
DobElement.Clear();
DobElement.SendKeys(""+num);

XPath:

IWebElement DobElement = driver.FindElement(By.XPath("//input[contains(@id, '_Ins_txtDob') and contains(@name, 'txtDob')][contains(@onblur, 'InputValidation')]"));
DobElement.Click();
DobElement.Clear();
DobElement.SendKeys(""+num);

@DebenjanB could you explain the code why to include the onBlur but not other events like keypress, keydown

As you pointed out, virtually we could have considered onkeydown or onkeypress just like onblur. But if you observe the onkeydown event it's pretty generic and can be present for majority of the <input> elements. Same goes for onkeypress. Both of the alternatives should work. I choose to pick onblur as this event will be the last event among the three events to be fired which may be the last event to be rendered within the HTML.
