Solution 1

use this

C#

public string FromDate
   {
       get {
           if (txtFrmDate.Text.ToString() != "")
           {

               _fromDate = Convert.ToDateTime(txtFrmDate.Text, _cInfo);

           }
           else
           {
               txtFrmDate.Text = DateTime.Now.AddMonths(-3).ToString("dd-MM-yyyy");
               _fromDate = Convert.ToDateTime(txtFrmDate.Text, _cInfo);
           }
           return _fromDate.ToString();
       }
       set
       {
           txtFrmDate.Text = value;
       }

   }

assign the value as below

C#

FromDate = DateTime.Now.ToString();

You need to write capital T and S in tostring.
i thought you know that
now i modified you try it.

Sorry to say ,Three errors occured

Error1 'System.DateTime' does not contain a definition for 'tostring' and no extension method 'tostring' accepting a first argument of type 'System.DateTime' could be found (are you missing a using directive or an assembly reference?)
Error2 The best overloaded method match for 'string.ToString(System.IFormatProvider)' has some invalid arguments
Error3 Argument 1: cannot convert from 'string' to 'System.IFormatProvider'

Solution 2

the code is here
http://www.java2s.com/Code/ASP/Development/ConvertdatetostringC.htm[^]

I used that but got error on set part, are following
Error1 The best overloaded method match for 'string.ToString(System.IFormatProvider)' has some invalid arguments Error2 Argument 1: cannot convert from 'string' to System.IFormatProvider'

This is the line Which have error
---------------------------------
set
{
txtFrmDate.Text = value.ToString("dd-MM-yyyy");
}

Solution 4

You should use DatetimeDateTime..::.TryParseExact Method[^] for converting. Also make sure you specify the format you are expecting.

This method has 2 variants, both are well explained in msdn link. Refering should help.

Solution 3

Its working try

private DateTime _fromDate = DateTime.Now;
   static  public   string  cultureName = "en-US";
   System.Globalization.CultureInfo culture = new CultureInfo(cultureName);
   public DateTime FromDate
   {

       get
       {
           if (txtFrmDate.Text.ToString() != "")
           {

               _fromDate = Convert.ToDateTime(txtFrmDate.Text);

           }
           else
           {
               txtFrmDate.Text = DateTime.Now.AddMonths(-3).ToString();
               _fromDate = Convert.ToDateTime(txtFrmDate.Text,culture);
           }
           return _fromDate;
       }
       set
       {
           txtFrmDate.Text = value.ToString("dd-MM-yyyy");
       }


   }

Error in line 15:String was not recognized as a valid DateTime.

The particular line is:
------------------------
_fromDate = Convert.ToDateTime(txtFrmDate.Text,culture);

txtFrmDate.Text = value.ToString();

I just used this line
_fromDate = Convert.ToDateTime("2009/02/03", culture);

Its working fine with any culture. Problem is with your AddMonths
