Extra line at top of form after port to 4.0

Hi:
I am experiencing extra line at top of form after I have ported from 3.5 sites to 4.0 sites. The 'extra line' jumps down after rendering. Sometimes as one moves the mouse over say a tab control then it jumps back to 3.5 normal.
The navy blue bar is supposed to be against the top of the browser page. I have changed things from 100% to 99.9%
The following is the master page:

Download Packages

Hi,

Where can I download the actual installer packages from now?
I do not want to use this control panel for installing and managing the controls and applications as it is just not convenient.
I sometimes have to use different machines depending on what I am doing, and have to install on a fairly regular basis, and the way it works now, I have to download the packages every time I want to install them, and they are all installed automatically. There does not appear to be an option to 'Download but do not install'

This is a classic case of 'Simplifying' where it actually has the opposite effect.

Thank you

Paul

radgrid clentside pagination while updating and inserting records from web service

Hello there,

I have gone through the solutions that telerik has posted such as:
http://www.telerik.com/community/forums/aspnet-ajax/grid/radgrid-clientside-pagination.aspx

What I am trying to do is calling webservice methods to update and insert records but the result set contains all the records which are displayed on a single page when I try to bind it on client side. Please give me a solution to solve this issue.

Test scenario: Select a page other than page 1 and try to edit or insert a record. The updated/inserted record should be selected by default. But it is not working as desired.

Thanks

problem with onbeforeunload and radajaxloadingpanel

Hello,

I have a webpage that has a grid on it, the grid opens in edit mode and functions exactly as needed. I have it so it saves everytime you go to filter, sort rows, change page size, etc...all per user request. The last request was to force a save when they leave the page. I am attempting to do it with

window.onbeforeunload = function (evt) {

$find("<%=RadAjaxManager1.ClientID %>").ajaxRequest();

}

This forces the page to save and works as needed, they do not want confirmation, they want it to save no matter what. My issue is that when I put the above code on the page, the radAjaxLoadingPanel no longer displays on any item command clicks or on paging, sorting. It only shows up on filtering. I have no idea why this may be occuring.
Below I will paste all my code so you can see everything that is occuring. If you have any other thoughts please let me know. If you notice anything else that does not look correct, please let me know. I am new to learning telerik and these pages but am pretty happy with what I have programmed so far and everything aside from the "LoadingPanel" right now works as needed.Thank you in advance.

Header Context Filter Menu ignoring SortExpression

I have a grid where several columns sort on a sortexpression that is not the same as the datafield. If I click the column the sort cycles ascending, descding, no sort correctly and sorts on the field defined in the sortexpression. If I chose the ascending or descending sort options from the Context Header Menu, the colum sorts on the datafield. Is there a way to make the sort from the Filter Menu use the sortexpression field?

Separators for Databound Items

Hello,

I want to bind a RadListBox to a list of a simple class:

Public Class ExampleInfo

Property ID as integer

Property Text as String

Property Category as string

End Class

I would like to add separators to the list by category. Physically, that's easy - I just made the separator items disabled and applied a special css class. But, I am having trouble positioning them. Here's been my current approach:

Private _curCategory as string = ""

Private Sub mainList_ItemDataBound(sender As Object, e As Telerik.Web.UI.RadListBoxItemEventArgs)

Dim dataRow As ExampleInfo = DirectCast(e.Item.DataItem, ExampleInfo)

Dim LocalCategory as string = dataRow.Category

If _curCateogry <> LocalCategory Then

Dim sepItem As New RadListBoxItem(LocalCategory, 0)

sepItem.Enabled = False

sepItem.CssClass = "listSeparator"

sepItem.Attributes.Add("isSeparator", "True")

mainList.Items.Add(sepItem)

End If

e.Item.Attributes.Add("isSeparator", "False")

e.Item.ToolTip = dataRow.Description

End Sub

This adds the items just fine but, of course, they are added below the first item in the new category. I tried reordering them in the DataBound event for the list but I haven't been able to get that to work.

Can anybody help - how can I add separator items?

Thanks,

Mike

Nested Grid issues

The following code is used to render a Grid with a nested grid, all Data is bound using NeedDataSource
The issues are as follows
1) there is no expand icon displayed
2) Master grid is reset when the child grid is displayed, the columns that were set using code behind are reset

So What I need is the following, The Delete row Icon is displayed only if the data has a Status of 'A'
If no delete icon is displayed the we will show a icon for Sucess or Failed or Processing

if the Status is Failed, then we should be able to expand the grid to see the errors listed, again if any other status then no expand to be displayed.

There are no internal styles to be used.
