The above snippet is just a portion of my class
Does anyone have any idea why SelectedRows would be undefined?
I originally had this posted in the older (non ajax) forum, so you may see a duplicate of this message there.
Thanks!

I started using Telerik controls for past 3 weeks…..
I am creating a Rad Grid Programmatically based on let’s say Query 2: is how many columns it is going to return from database. Query 2 results are based on Query1.
If Query 1 product type id is Q1A then Query 2 has 4 columns in it.
If Query 1 product type id is Q1B then Query 2 has 6 columns in it.
If Query 1 product type id is Q1C then Query 2 has 7 columns in it….So on.
Aspx page exactly looks like:
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:MultiView ID="MultiView1" runat="server" ActiveViewIndex="0">
<asp:View ID="View1" runat="server">
' Some CONTROLS in this VIEW1
</asp:View>
<asp:View ID="View2" runat="server">
<asp:UpdatePanel ID="UpdatePanel2" runat="server">
<ContentTemplate>
<telerik:RadGrid ID="rgvModels" runat="server" Width="950px" AutoGenerateColumns="False" Skin="SDDC" EnableEmbeddedSkins="False" AllowSorting="true">
<MasterTableView>
<Columns>
</Columns>
</MasterTableView>
<ClientSettings> <Scrolling AllowScroll="true" UseStaticHeaders="true" /> </ClientSettings> </telerik:RadGrid>
</ContentTemplate>
</asp:UpdatePanel>
</asp:View>
</ContentTemplate>
</asp:UpdatePanel>

rgvModels.Rebind()
MY QUESTION:
1) My rad grid will sort the first time very fine ascendingly.
2) If I try to click it again it will not sort again to descending order. Am I missing something here which it does not make it to sort descending?
3) I am even trying to clear sortexpressions in 3 places.
4) I saw this link
http://www.telerik.com/community/forums/aspnet-ajax/grid/how-to-clear-sorting.aspx
If this is the solution. I am sorry I don’t understand the Javascript solution to it. Leave alone the next solution by Maxim Tairov Posted on Jul 18, 2011. I definitely don’t get this.
PLEASE HELP.
Thanks,

Hai,
I have a problem with telerik ajax "Calendar".
I managed to set the "DateTime.now" on the page load and it is working perfectly for me.
But the problem is when I click to Navigate using the "prev month, prev year, next month or next year" a "default date is to be selected", instead here the prevoiusly selected date (that is DateTime.now value) exists if any one one of the "Navigation is clicked".
Actually I want a postback on the calendar click and I am plannning to load the data correspending to the "Selected Date". But here the selected date doesnot change on the Navigation Click.
You can see the "system calender" set a default value on the Navigation click to "default 1 st day of the corresponding Month and year".
Is it possible to set a default date on the Navigation month and year click. This is very much needed for this.
And as a workaround "Can we manage to set a default date on the clientside of the navigation cllick"
Any Help is appreciated,

Please hlelp on this issue , It is very urgent .
I need to do goup by (By Drag and drop ) . When I am using GridBoundColumn It is working fine. but when i am using
GridTemplateColumn with HeaderTemplate . I am not able to do drag and drop columns to do groupby and sorting the column also.I am not binding values in the header template . I am just arranging with a label with text value set directly and image.
Whether Is it mandatroy that i must bind some thing to the label in header template. I couldnt understand why it is not working .
Here is code i am using
<telerik:GridTemplateColumn GroupByExpression="CloseOutType" DataField="CloseOutType" SortExpression="CloseOutType" HeaderStyle-CssClass="xmediumcolsize" > <HeaderTemplate> <asp:Image ID="imgCloseOutType" ImageUrl="~/Images/closeout_type.png" runat="server" /> <asp:Label ID="lblheaderCloseOutType" runat="server" Text="Interim/Workbook" ></asp:Label> <%-- <asp:HiddenField ID="HiddenField1" Value='<%# eval("CloseOutType") %>' runat="server" />--%> </HeaderTemplate> <ItemTemplate> <asp:Label ID="lblCloseOutType" runat="server" Text='<%# eval("CloseOutType") %>'></asp:Label> </ItemTemplate> </telerik:GridTemplateColumn>Hello,
