Pagination is not working for self referencing hierarchy

Hi All,

I have implemented the self ref hierarchy in my page as per the instruction and it is working fine. but yesterday i found that when there are more than 15 records (15 is page size for grid) on secondary level grid shows pagination footer and after clicking on next page button (secondary level pagination) it updates primary level and navigate to the next page of grid instead of secondary levels next page. :(

Please help me..

This is my code
   <telerik:RadGrid ID="RadGrid1" AllowPaging="true" runat="server" PageSize="15">
   <PagerStyle Mode="NextPrevAndNumeric" />
   <MasterTableView HierarchyDefaultExpanded="true" HierarchyLoadMode="Client" Width="100%"
   DataKeyNames="PRIMARYSERIALNUMBER,SERIALNUMBER">
   <SelfHierarchySettings ParentKeyName="PRIMARYSERIALNUMBER" KeyName="SERIALNUMBER" />
   <Columns>
   <telerik:GridTemplateColumn>
   <ItemTemplate>
   <asp:HyperLink ID="hLinkName" runat="server" ToolTip='<%# DataBinder.Eval(Container.DataItem, "NAME") %>'> </asp:HyperLink>
   </ItemTemplate>
   </telerik:GridTemplateColumn>
   </Columns>
   </MasterTableView>
   </telerik:RadGrid>

Given the choice - asp.net vs winform

Given all the known advantages/disadvantages of doing an ASP.NET or a WinForm app, which way would you go if you are building an internal application and don't need the "Hey, I could go to ANY computer and get to the asp.net app!" advantage? I look at the number of threads in the asp.net forum and then the winform forum and I get the overwhelming sense that most are using asp.net.

It's been about 6 years since I've done any serious coding but I need to get back into the game to modernize myself. Therefore I may agree to write a fair sized application for a company. Telerik will enable me to accelerate the development of the app, etc. Now the choice becomes asp.net or winform?

I gravitate away from from asp.net because that platform just seems to fight you each step of the way. Things that are simple in winforms are not in asp.net. Are they truly that way or is because I have not done any significant coding in a while? It also seems that Telerik is embracing the browser apps more than winforms so that should confirm the continued tried of the industry towards asp.net.

I think I already know the response but if you got YOUR choice would you do the winform or the asp.net?

Listbox is Populated, but items are not visible

I have two RadListBox controls in a ASP.NET user control with the allowtransfer property set to true. I populate the RadListBox with RadListBoxItems on page load. The RadListBox is populated, but the text is not visible for any of the items. If I transfer the items to the other RadListBox, they transfer, but they are again not visible. I then refresh the page and I can see them in the second RadListBox. I transfer them back to the first RadListBox and the text is then visible in that listbox also. Please help, I can't seem to find what is causing the text to not display.

I have tried the following options without any success:
1) Made sure that ScriptResource.axd reference is in web.config <httphandlers> and <handlers> section.
2) I have replaced the telerik:radajaxpanel with asp:updatepanel
3) I have removed all the client side events from the list boxes.
4) I have made sure that order of ScriptManager is at the top of any other controls

Please suggest me how to proceed.

Error 'ColumnName' is neither a DataColumn nor a DataRelation for table Table.

In RadGrid we have a property "EnableColumnViewState" which can be set as false so that the grid when we add and remove columns across postbacks there is no error like "'ColumnName' is neither a DataColumn nor a DataRelation for table Table."

The same Error I am encountering in RadTreeList but i am unable to find a property like "EnableColumnViewState". Is there any Property like this available in RadTreeList currently. If not can anyone please tell me what else could be causing the issue.

Thanks In Advance.
