how to disable/enable telerik raddatepicker using javascript ????

[Shinu]

Hi Santosh,

Please have a look into the following JavaScript that I tried to enable/disable RadDatePicker in OnClientClicked event of RadButton.

ASPX:

<telerik:RadDatePicker ID="RadDatePicker1" runat="server">
</telerik:RadDatePicker>
<telerik:RadButton ID="RadButton1" runat="server" Text="Enable/Disable DatePicker"
    AutoPostBack="false" OnClientClicked="OnClientClicked1">
</telerik:RadButton>

JavaScript:

<script type="text/javascript">
    function OnClientClicked1(sender, args) {
        var datepicker = $find("<%=RadDatePicker1.ClientID %>");
        if (datepicker.get_enabled() == false)
            datepicker.set_enabled(true);
        else
            datepicker.set_enabled(false);
    }
</script>

Thanks,
Shinu.

I am trying the same but not working. but one different is I am using Master page. So any other ideas appreciated!

Arumugam,

The approach when a Master page is used, should not be much different.
A possible problem in such a scenario could be the server expression for getting a reference to the RadDatePicker (<%= %>). The server expression can only be used when the script and the DatePicker declaration reside on the same aspx page.

In any other case you can use another approach to get a reference to the RadDatePicker client-side object. Check out different ways to Get Client-side Reference to a Control Object.

For instance, you can try the following:
JavaScript

function OnClientClicked1(sender, args) {
    var datepicker = $telerik.findControl(document,"RadDatePicker1");
    if (datepicker.get_enabled() == false)
        datepicker.set_enabled(true);
    else
        datepicker.set_enabled(false);
}

ASPX

<telerik:RadDatePicker ID="RadDatePicker1" runat="server">
</telerik:RadDatePicker>
<telerik:RadButton ID="RadButton1" runat="server" Text="Enable/Disable DatePicker"
    AutoPostBack="false" OnClientClicked="OnClientClicked1">
</telerik:RadButton>

If this is not the case please share some more information about the current case so we can assist more accurately.
