Enable asp button on RadCombobox and RadDatePicker

[Salman]

In a form, I have both RadComboBox and RadDatePicker and I want to enable an asp button if any change is made to them. How I can make it possible.

I use below code for textboxes and it's working fine:

$(document).ready(function () {

    $("#BtnUpdate").attr('disabled', 'disabled');

    $("input.UpdateCSS").keyup(function () {
        $("#BtnUpdate").removeAttr('disabled');
    });



    $("input.UpdateCSS").change(function () {
        $("#BtnUpdate").removeAttr("disabled");
    });

What I need is what could be used as alternative for 'keyup' and 'change ' when we have RadCombobox and RadDatePicker

Hi Salman,

You can leverage the following event handlers to achieve this requirement:
http://docs.telerik.com/devtools/aspnet-ajax/controls/combobox/client-side-programming/events/onclientselectedindexchanged
http://docs.telerik.com/devtools/aspnet-ajax/controls/datepicker/client-side-programming/events/ondateselected​

Also, you can try replacing your regular button with RadButton, which provides set_enabled() method:

I hope this will prove helpful.

Hi Eyup,

Thanks for your reply.

the solution works perfectly for RadCombobox.

For RadDatePicker, ondateselected is not what I'm looking as the event triggered when Datepicker has a value which for my case, it has a default value (I'm looking for an event to detect change). Like onclientselectindexchanged, I'm looking for a client-side event or a workaround to solve the issue.

Hello Salman,

In this case, you can try using the ValueChanged event handler of the date input:
http://docs.telerik.com/devtools/aspnet-ajax/controls/input/client-side-programming/events/overview

Here is a demonstration:

<telerik:RadDatePicker ID="RadDatePicker1" runat="server">
    <DateInput runat="server">
        <ClientEvents OnValueChanged="yourHandlerName" />
    </DateInput>
</telerik:RadDatePicker>
