LinqDataSource+RadGrid+server side caching issue

I used example from http://demos.telerik.com/aspnet-ajax/grid/examples/performance/linq/defaultcs.aspx to cache a data. I added just OrderBy="Name" to LinqDataSort. When ASP.NET form is opened first time everything is good but after paging the sort order is not right. As I understand the issue Linq does OrderBy just when querying data from the database. How to resolve this issue? I have to keep the column Name sorted all time.

<asp:LinqDataSource ID="LinqIdDataSource" runat="server" AutoPage="false"

TableName="V_ID_Dailies" Select="new (ID, Name)"

ContextTypeName="IdLookupDataContext"

OrderBy="Name" OnContextCreating="LinqIdDataSource_ContextCreating"

OnSelected="LinqIdDataSource_Selected" OnSelecting="LinqIdDataSource_Selecting">

</asp:LinqDataSource>

Header Gridlines are overlapping (IE7)

My RadGrids have static headers and i am freezing the first 2 columns.
In Firefox and IE8, the radgrids are very smooth in their scrolling and everything is rendering excellently.
When I switch to IE7 compatibility mode, (or other coworkers view the site in old IE7), the header grid lines are overlapping on top of each other.

I can post my code if you all need to see it, but perhaps this is a simple fix that I am just not getting...

screen shots attached

thanks for any help!

Expand / collapse image size

I have a need to display a hierarchical grid on a touch-screen. The customer is requesting that the size of the buttons be larger for this purpose. I have tried overriding the image size using the following CSS override:

div.RadGrid .rgExpand,

div.RadGrid .rgCollapse

{

height:32px;

width:32px;

}

which works, however the image is located on the top left corner. It would be nicer if it were centered. Is there a better way of accomplishing this? if not is there a way to center the image?

Thanks, Steve

there is a shift between the header and the columns

when i use the grid with with scroll that the headrer is static "<Scrolling AllowScroll="true" UseStaticHeaders="true" />"
there is a shift between the header and the data columns .
i use "RTL" language and my telerik version is "2009.1.402.20" and the runtime version is "v2.0.50727".
when i remove the UseStaticHeaders="true" everything work fine, and it also work good with IE7.

Chrome and ComboBox

I have a combobox in a table like this:

<table width="100%">

<tr>

<td width="40px">

<telerik:RadComboBox ID="TitleArticle" runat="server" Width="40px">

<Items>

<telerik:RadComboBoxItem runat="server" Text="A" Value="A" />

<telerik:RadComboBoxItem runat="server" Text="An" Value="An" />

<telerik:RadComboBoxItem runat="server" Text="The" Value="The" />

</Items>

</telerik:RadComboBox>

</td>

<td>

<telerik:RadTextBox ID="ShortTitle" runat="server" Width="100%">

</telerik:RadTextBox>

</td>

</tr>

</table>

Firefox gets it right, in Chrome the ComboBox is too wide, it's not listening to the width. See the attachment.

[Solved] Missing Control: FileExplorer

Although the built-in skins include this control VSB neither allows it to be modified or includes it in the generated download.

As I'm trying to skin the RadEditor I really rather need this.
