[Solved] Filter DropDown with LoadOnDemand enabled

Hi,

I'm trying to establish a filter-drop-down as described in this demo.
It basically works out BUT as the combo contains > 10k of possible entries, LoadONDemadn became mandatory.

It basicall does work out with the following configuration:

<telerik:GridDropDownColumn DataSourceID="DataSource" ListTextField="name" ListValueField="kID"

DataField="cdf" FilterControlAltText="Filter cdf column" HeaderText="cdf"

SortExpression="cdf" UniqueName="cdf">

<FilterTemplate>

<telerik:RadComboBox ID="RadComboBoxCustomer" DataSourceID="Customers" DataTextField="name"

DataValueField="kID" EnableAutomaticLoadOnDemand="true" AppendDataBoundItems="true"

SelectedValue='<%# ((GridItem)Container).OwnerTableView.GetColumn("cdf").CurrentFilterValue %>'

runat="server" ItemsPerRequest="10" EnableVirtualScrolling="true" OnClientSelectedIndexChanged="TitleIndexChanged" Skin="Metro">

<Items>

<telerik:RadComboBoxItem Text="All" />

</Items>

</telerik:RadComboBox>

<telerik:RadScriptBlock ID="RadScriptBlock1" runat="server">

<script type="text/javascript">

function TitleIndexChanged(sender, args) {

var tableView = $find("<%# ((GridItem)Container).OwnerTableView.ClientID %>");

tableView.filter("cdf", args.get_item().get_value(), "EqualTo");

}

</script>

</telerik:RadScriptBlock>

</FilterTemplate>

</telerik:GridDropDownColumn>

However, when i remove the text in the filter-dropdown (i.e.try to filter for another record). i get a "Parameter cannot be null exception" which is due to the intermediate filter entry having no value, but the filter tries to sort i think?

Is there a way to overcome this issue? Any hint is highly appreciated.

Multiple File Upload issues (Chrome, FF)

Background:
Recently upgraded a project that uses the AJAX toolkit to the bleeding edge version to get the radscheduler to work with resource grouping and have found that it broke the uploader that a different part of the project uses.

Currently the project is using v.2012.1.424.40

Issue:
When ever a user tries to select multiple files from the file browser, or tries to click on the select the browse button more than once per post back, anything past the first file will get stuck in Chrome and FF. It seems to work ok in IE9. Below is the tag declaration.

<telerik:RadAsyncUpload ID="RadAsyncUpload1" runat="server" MultipleFileSelection="Automatic" AutoAddFileInputs="true" />

Other things to note is the upload control is loaded in a fancybox window. It worked before the upgrade without issue, but might be causing an issue now with the newer control version.

I'm thinking its something to do with the File API not playing nice.

Radgrid inside scrolling div resets scroll position

I have a radgrid inside a div set to overflow auto. If you scroll down and select a row the div's scroll position gets reset to the top. Tried using built-in scroll functionality but this didn't work (layout breaks and only background of template cells scroll without scrolling other elements). Tried JavaScript to reset scrollTop property of div on active row changed but this also didn't work. Help?
