Problem with RadGrid GridCalculatedColumn Expression

I have a grid with a column defined as follows:
<telerik:GridCalculatedColumn FilterControlAltText="Filter column1 column" UniqueName="YrPercent"
DataFields="Jan,Feb,Mar,Apr,May,Jun,Jul,Aug,Sep,Oct,Nov,Dec,minTotal"
Expression="(({0} + {1} + {2} + {3} + {4} + {5} + {6} + {7} + {8} + {9} + {10} + {11}) / {12}) * 100.0"
Aggregate="Sum" HeaderText="Yr %" DataFormatString="{0:N3}%" FooterAggregateFormatString="{0:N3}%"
DataType="System.Double" FilterControlWidth="30px">
<FooterStyle HorizontalAlign="Right" />
<HeaderStyle Width="3.5%" HorizontalAlign="Center" />
<ItemStyle HorizontalAlign="Right" />
</telerik:GridCalculatedColumn>

As you can see, I'm looking for a percentage (in this case rather small ones, about .147 for example). All of the fields referenced in the calculation are integers. I've bound the grid with a call to a IQueryable method returning a call from LinqToSQL.

As is, this grid crashes with a Operator '*' incompatible with operand types 'Int32?' and 'Double' error. After much searching of your forums, I set the grid's EnableLinqExpressions property = false and everything seems to work.

2 questions.

Is there any way to get that expression to work without setting EnableLinqExpressions=false?
What do I lose if I do set EnableLinqExpressions=false?

Issue with AutoPostBack RadComboBox inside RadGrid GridTemplateColumn

I'm trying to add a AutoPostBack enabled RadComboBox to the ItemTemplate of a RadGrid's GridTemplateColumn. The RadComboBox relies on certain row data so I'm creating it dynamically using the grid's ItemDataBound event:

protected void rgFaqs_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)

{

if (e.Item.ItemType == Telerik.Web.UI.GridItemType.Item || e.Item.ItemType == Telerik.Web.UI.GridItemType.AlternatingItem)

{

FaqListItem item = (FaqListItem)e.Item.DataItem;

if (item == null)

return;

WorkflowComboBox workflowBox = new WorkflowComboBox();

workflowBox.ItemID = item.Id;

workflowBox.DataBind();

PlaceHolder phWorkflowBox = (PlaceHolder)e.Item.FindControl("phWorkflowBox");

phWorkflowBox.Controls.Add(workflowBox);

}

Here is a snippet of my custom overridden WorkflowComboBox:

public class WorkflowComboBox : Telerik.Web.UI.RadComboBox

{

public int ItemID { get; set; }

public WorkflowComboBox()

{

AutoPostBack = true;

}

protected override void OnInit(EventArgs e)

{

this.SelectedIndexChanged += new RadComboBoxSelectedIndexChangedEventHandler(WorkflowComboBox_SelectedIndexChanged);

EnsureChildControls();

base.OnInit(e);

}

Like I said, this works perfectly fine on the initial page load. The problem occurs on the AutoPostBack of the ComboBox. This causes a postback which doesn't appear to be firing the ItemDataBound event again. That in turn causes my the Combobox field to not be loaded properly.

I've also tried moving the ItemDataBound stuff to the RadGrid's ItemCreated event instead. Everything works fine on first page load. When the ComboBox AutoPostBack gets fired though, the e.Item.DataItem is null.

I'm getting the vibe that this is an issue/conflict? with the event sequence of the RadGrid and the RadComboBox. It also appears during this whole process that the RadComboBox SelectedIndexChanged event is never being reached.

Any thoughts? Am I missing something!?

-Thanks
