DateTimeFormat DD/MM/YYYY in Ajax tool kit 4.0

Introduction

We use Date Time Format in a dd/mm/yyyy using Ajax Tool Kit 4.0

Background

Some problem using DateTimeFormat in a dd/mm/yyyy with using AjaxToolKit 4.0. mostly programmer avoid to using calender extender due to some reason.

Using the Code

Firstly you add up CultureInfo class through System.Diagnostic name space,then use the TRYPARSExact method for correct date time format.so Don,t Forget to add up a property name of "CULTURE NAME" in MaskEditExtender (Below which is mark in a REd colour).

stStartDate  = txtStartDate1.Text;
stEndDate    =  txtEndDate1.Text;
CultureInfo enBR = new CultureInfo("pt-BR");

// check date Time Format 

DateTime startDate = new DateTime();

DateTime endDate = new DateTime();

if(txtStartDate1.Text == "__/__/____" && txtEndDate1.Text =="__/__/____")
{ }           
 if(txtStartDate1.Text != "__/__/____" || txtEndDate1.Text !="__/__/____")

 {   
    if (txtStartDate1.Text != "__/__/____" && txtEndDate1.Text !="__/__/____")

           {              
               if (DateTime.TryParseExact(stStartDate,"dd/MM/yyyy",
                  enBR,DateTimeStyles.None,out startDate)
                  && DateTime.TryParseExact(stEndDate,"dd/MM/yyyy",
                  enBR,DateTimeStyles.None,out endDate) )
                 {
                     // something 
                 } 
          }
  }
