When using RadDatePicker inside RadGrid Prometheus I can't find Enable/Disable Javascript functionality

[Mark]

Hi

I'm using VS2008, .NET 3.5 and C#.

I use RadDatePickers inside a Prometheus RadGrid. I can successfully reference these RadDatePickers in Javascript and can perform functions like GetMinDate().

However in 

ms-help://telerik.radcontrols.prometheus.2007.Q3/telerik.radcontrols.prometheus.2007.Q3/cldClientSideAPI.html

there is functionality for enabling / disabling this control which isn't working for me. Basically it can't find "DateInput" and "PopupButton".

Please let me know if you require an further information.


Kind regards

Hello Mark,

It seems that the help article has not been updated properly for the Prometheus version of our controls. We will do that for the Q3 2007 SP1 version of our controls, expected in the middle of this month. For your convenience I am pasting the modified code snippet in this support thread:

            <asp:ScriptManager ID="ScriptManager1" runat="server">
            </asp:ScriptManager>
            <telerik:RadScriptBlock ID="RadScriptBlock1" runat="server">

                <script type="text/javascript">
                var isPopupOpening = true;

                function disable()
                {
                    var datepicker = $find("<%=RadDatePicker1.ClientID %>");
                    $get(datepicker.get_dateInput().get_id() + "_text").disabled = "disabled";
                    isPopupOpening = false;
                }

                function enable()
                {
                    var datepicker = $find("<%=RadDatePicker1.ClientID %>");
                    $get(datepicker.get_dateInput().get_id() + "_text").disabled = "";
                    isPopupOpening = true;
                }

                function PopupOpening(sender, args)
                {
                    if(!isPopupOpening)
                    {
                      args.set_cancel(true);
                    }
                }
                </script>

            </telerik:RadScriptBlock>
            <telerik:RadDatePicker ID="RadDatePicker1" runat="server">
                <ClientEvents OnPopupOpening="PopupOpening" />
            </telerik:RadDatePicker>
            <br />
            <a href="javascript:disable();">Disable</a> <a href="javascript:enable();">Enable</a>

A sample project is enclosed to this forum post for further reference.

Hi

Thanks for the reply, it put me on the right track. As I'm in a grid, instead of using a variable I checked if the DatePicker was enabled. E.g.

function

dateTo_PopupOpening(sender, e)
{
    // If the RadDateInput is disabled then we want to prevent the calendar popup
    if($get(sender.get_dateInput().get_id() + "_text").disabled)
        e.set_cancel(true);
}

Now works beautifully!

Thanks again.


Kind regards
