Unable to get value of the property 'style': object is null or undefined

Hello,,
I have aproblem with the radtooltip control (demo: http://demos.telerik.com/aspnet-ajax/tooltip/examples/onclientresponseend/defaultcs.aspx).
I always got the webpage error : Unable to get value of the property 'style': object is null or undefined.
If I remove the following javascript lines then the error doesn't display:

$get("startRequest").style.display = "none";

$get("endRequest").style.display = "";

Note: I'm using the version 2009.3.1314.35

Please, I need your help,

RadComboBox OnSelectedIndexChanged

I am trying to use the Selected index of one RadComboBox help build the query to populate another RadComboBox, they are both in the <EditItemTemplate>.
I get an Object reference not set to instance of an object when I run this code just adding a RadComboBoxItem without even building the query.

Protected Sub ItemType_SelectedIndexChanged(ByVal o As Object, ByVal e As RadComboBoxSelectedIndexChangedEventArgs)

Dim DDL As RadComboBox = TryCast(RadGrid1.FindControl("FlatFileType").Controls(0), RadComboBox)

Dim RadComboBoxItem1 As New RadComboBoxItem("First Item")

DDL.Items.Add(RadComboBoxItem1)

End Sub

I am not sure how to correctly access the second radcombobox to be able to populate it.
Any help is greatly appreciated.

Add New button (Insert mode) does not work

If i comment out the selectvalue portion it works and i am able to ADD NEW Item.

If TypeOf e.Item Is GridEditableItem AndAlso e.Item.IsInEditMode Then

Dim editedItem As GridEditableItem = CType(e.Item, GridEditableItem)

Dim Manufacturers As RadComboBox = CType(editedItem.FindControl("ManufacturerEdit"), RadComboBox)

ProductsAccess.BindManufacturers(Manufacturers)

'Dim Manufacturer As Integer = DataBinder.Eval(editedItem.DataItem, "Manufacturer").ToString

'Manufacturers.SelectedValue = Manufacturer

Dim Categories As RadComboBox = CType(editedItem.FindControl("CategoryEdit"), RadComboBox)

ProductsAccess.BindCategories(Categories)

'Dim Category As Integer = DataBinder.Eval(editedItem.DataItem, "Category").ToString

'Categories.SelectedValue = Category

If i un-comment those lines i am only able to EDIT the items but when i click add new button it does nothing.

If TypeOf e.Item Is GridEditableItem AndAlso e.Item.IsInEditMode Then

Dim editedItem As GridEditableItem = CType(e.Item, GridEditableItem)

Dim Manufacturers As RadComboBox = CType(editedItem.FindControl("ManufacturerEdit"), RadComboBox)

ProductsAccess.BindManufacturers(Manufacturers)

Dim Manufacturer As Integer = DataBinder.Eval(editedItem.DataItem, "Manufacturer").ToString

Manufacturers.SelectedValue = Manufacturer

Dim Categories As RadComboBox = CType(editedItem.FindControl("CategoryEdit"), RadComboBox)

ProductsAccess.BindCategories(Categories)

Dim Category As Integer = DataBinder.Eval(editedItem.DataItem, "Category").ToString

Categories.SelectedValue = Category

ProductsAccess.BindManufacturers(Manufacturers) is a pretty simple Sub that bind combobox to datatable. I even tried with iterating DataRows in the DataTable.Rows collection and populating the combo one by one. The problem persisted :(
THanks
