Do postBack when the RadComboBox's selection has changed

Hello,

I'm trying to achieve the following: if the selection of the drop down has not changed, do not postBack. if the selection has changed, do postBack. How would I achieve this? I tried to change OnClientDropDownClosing to OnClientSelectedIndexChanged but the OnClientSelectedIndexChanged event was not fired.

I'm using version 2009.2.701.35. My sample code is as below. Thanks for your help!

Disable Built In Validation

Hi,

Is there a way where Drag and drop shoud not be allowed for the dates lesser than Current date?

Also any way to disable the built in validation in Rad Scheduler?

In my Case, I am using Advance Edit template to update the appointment.
Start Date and End Date are same.
I am interested just in the Start Date and time of the appointment and want to update the same thru double click
ASPX Code here:

<telerik:RadScheduler ID="rsSchedule" runat="server" DataEndField="InducDt" DataKeyField="ID"

DataStartField="InducDt" DataSubjectField="SlotDesc" FirstDayOfWeek="Monday"

LastDayOfWeek="Saturday" OverflowBehavior="Expand" SelectedView="MonthView" Culture="English (United States)"

DayEndTime="19:00:00" DayStartTime="08:00:00" EditFormDateFormat="MM/dd/yyyy"

EditFormTimeFormat="h:mm:tt" Height="500px" MonthVisibleAppointmentsPerDay="3"

EnableEmbeddedSkins="true" ShowViewTabs="true" Skin="Hay" BackColor="#98cb33"

DisplayRecurrenceActionDialogOnMove="True" ShowFullTime="True" AllowDelete="false"

AllowInsert="false" TimelineView-UserSelectable="false" CustomAttributeNames="Deliverables">

<br />

</td>

</tr>

<asp:Label ID="lblDescription" AssociatedControlID="lblSubject" runat="server" Text="Description"

Font-Bold="true">

</asp:Label>

</td>

</tr>

<br />

<asp:Label ID="lblSubject" runat="server" Text='<%# Bind("Subject") %>'>

</asp:Label>

</td>

</tr>

<br />

</td>

</tr>

<tr>

<asp:Label ID="lblDate" AssociatedControlID="rdtpFrom" runat="server" Text="Induction Date"

Font-Bold="true"></asp:Label>

</td>

<telerik:RadDateTimePicker ID="rdtpFrom" runat="server" DateInput-ReadOnly="true"

SelectedDate='<%# Bind("Start") %>' MinDate='<%# Date.Now.Date %>' TimeView-StartTime="08:00:00"

TimeView-EndTime="19:15:00" TimeView-Interval="00:15:00" TimeView-Columns="4">

</telerik:RadDateTimePicker>

</td>

</tr>

</table>

<br />

</td>

</tr>

<asp:ImageButton ID="btnUpdate" runat="server" CommandName="Update" ImageUrl="~/Images/update.gif"

CausesValidation="false" />

<asp:ImageButton ID="btnCancel" runat="server" CommandName="Cancel" ImageUrl="~/Images/Cancel.gif"

CausesValidation="false" />

</td>

</tr>

</table>

</div>

</AdvancedEditTemplate>

</telerik:RadScheduler>

Now while editing if I select a date lesser the InductDt(the field from the database binded to Start and End Date) it works fine.
But if I select a date greater than the InducDt it gives me an error saying that the 'Appointment Start Date and Time should be less than the End Date and Time'.
I have even tried setting the Causes Validation property of the Update Btn to false and setting the Validation Group of the Scheduler to blank. But no use

Please suggest a way out of this.

ScaleBreaks implementation problem

Hi guys. The documentation does not say how to implement ScaleBreaks. You just simply mentioned that it is a feature. I've tried for several hours to get it to work but I cannot.

asp Radwindow demo fail

Here i found a missing ";" after contentWindow as follows:

// Get a reference to the first RadWindow's content

var contentWin = dialog1.get_contentFrame().contentWindow

url:

http://demos.telerik.com/aspnet-ajax/window/examples/dialogreturnvalue/defaultcs.aspx

its in the code example C# Dialog2.aspx in the javascript block in function returnValue()

...

or anything else is wrong, my compiler tells me that get_contentFrame().contentWindow is null or not an object...

with contentWindow (); he tells me that get_contentFrame() is null or not an obejct.

sure that its correct without ; or (); ?

cheers uspec

Horizontal Scrolling and Keyboard Navigation

I currently have a RadGrid wired up with 42 columns. Naturally, I have horizontal scrolling and column freezing enabled. However, when I try to use the keyboard to scroll (using the tab key), I do not get the expected behavior. Namely, the scroll bar does not move as I tab between cells. This causes glitchy behavior, especially if I want to scroll back to teh left (since the bar has not moved, this is difficult). Does Telerik's RadGrid support full-on keyboard navigation & I'm implementing it wrong? Any help would be great!
