title: Not showing data in month and year dropdown in datepicker
body: <p>I am using JQuery datepicker with month and year value.</p>
  
  <p>but the problem is, in the dropdown of month and year, only white spaces are visible, if I hover in the opened dropdown then only month and year respectively are visible. If I take mouse away, there is only blank white dropdown, again I hover in dropdown list, month and year is visible. I can select then. The only problem is it is not visible.</p>
  
  <p>My code for datepicker</p>
  
  <pre><code>&lt;script type="text/javascript"&gt;
          jQuery(function ($) 
          {
              $("#&lt;%= txtDOB.ClientID %&gt;").datepicker({
                  changeMonth: true,
                  changeYear: true,
                  dateFormat: 'mm/dd/yy'
              });
          });
      &lt;/script&gt;  
  </code></pre>
  
  <p>textbox in which i am applying it:</p>
  
  <pre><code>&lt;div class="col-sm-5"&gt;
                          &lt;asp:TextBox ID="txtDOB" runat="server"  placeholder="mm/dd/yyyy"&gt;&lt;/asp:TextBox&gt;
                      &lt;/div&gt;
                      &lt;div class="col-sm-4 no-padding"&gt;
                          &lt;p class="error"&gt;
                              &lt;asp:RegularExpressionValidator ID="RegularExpressionValidator_txtDOB" ValidationGroup="Employee"
                                  runat="server" ErrorMessage="Invalid Date.." ControlToValidate="txtDOB"
                                  ValidationExpression="^([0-9]{1,2})[./-]+([0-9]{1,2})[./-]+([0-9]{2}|[0-9]{4})$"&gt;&lt;/asp:RegularExpressionValidator&gt;
                          &lt;/p&gt;
                      &lt;/div&gt;
