What more than:

C#

d1 = DateTime.Now;
d2 = DateTime.Now.AddDays(12);

if (d2 > d1)
{
    // date order ok
}
else
{
   // date order reversed
   // swap the dates ?
}

Do you want ?

Do you want to specify minimum and/or maximum intervals (TimeSpan) between the two Dates ?

Do you want a very specific DateTime validator where the criteria are fixed, or do you want a general purpose validator you can pass parameters into that handle a variety of conditions ?

How about excluding certain Date intervals if they include any weekend day, or any specific range of hours of day, or night ?

Let's see some of your code.

I got my solution and posted it and it is working for me.

Solution 2

Get date from controls using DateTime.TryParse method[^] and compare them. That's all!

The below method should show in button validation,

C#

string valid = CheckValid();
if (valid == "")
{ 
    errormsg.Text = valid;
}

The method should define here

C#

private string CheckValid()
{
    try
    {
        string valid;
        if (txtFromDate.Text != string.Empty && txtToDate.Text != string.Empty)
        {
            DateTime startdate = DateTime.Parse(txtFromDate.Text);
            DateTime enddate = DateTime.Parse(txtToDate.Text);
            if (startdate > enddate)
            {
                txtFromDate.Focus();
                return valid = "From Date is Should be less than To Date";
            }
            else
            {

            }
        }

        return valid = "";
    }
    catch (Exception Ex)
    {
        throw (Ex);
    }
}
