Hi everyone.

 

I have two requirements for date picker.

 

First I need a date picker object without the calendar day’s part where the user can only select a month and a year.

 

And second I need to be able to enable/disable the date picker depending on what option user selected in the radio button list control.

 

For the first requirement I found a custom implementation on

http://www.telerik.com/community/code-library/submission/b311D-mdkhb.aspx

and it is working just fine.

 

But when I try to disable date picker with ‘picker.set_enabled(false);’ statement

I am getting the following error:

Microsoft JScript runtime error: Sys.InvalidOperationException: Handler was not added through the Sys.UI.DomEvent.addHandler method.

 

Here is my simple web page:
Some how I placed 3 code blocks.
Please look at the top one only and ignore the other two.

Hi Igor,

To enable or disable a RadDatePicker control, you need to call the set_enabled(true/false) client-side method of the Picker client-side object. Please find more information in the following help article:
Client-Side Basics (Enabling and disabling the RadDatePicker ........  section)

I hope this helps.

Sincerely yours,

Pavlina,

Thanks for reply.

I am using set_enabled(true/false) to enable/disable RadDatePicker.

My problem is that I am getting an error when I am using this method on RadDatePicker with custom implementation found here:

http://www.telerik.com/community/code-library/submission/b311D-mdkhb.aspx.
Please, try the code sample that I posted (just the top code block).   

Igor.

Hello Igor,

The following modification on the code run as expected on my side:
  • remove the RadioButtonList and its functionality for clarity.
  • add a button performing the enable / disable functionality like this:
<input type="button" value="Enable / Disable" id="Button1" onclick="Toggle()" /> 

  • add the following client side function:
function Toggle(sender, args) 
            { 
                var picker = $find("<%= RadDatePicker1.ClientID %>"); 
picker.get_dateInput().set_enabled(!picker.get_dateInput().get_enabled()); 
                if (!picker.get_dateInput().get_enabled()) 
                { 
                    picker.get_popupButton().style.display = "none"; 
                    picker.get_dateInput().disable(); 
                } 
                else 
                { 
                    picker.get_popupButton().style.display = "block"; 
                    picker.get_dateInput().enable(); 
                } 
            } 

I hope this helps.
