Hello,

I have a small question, about the SortExpression in a GridTemplateColumn.
In fact, I have a SQL table [Action] and a table [PlanActionNiveauDeRealisation]. Like this an [Action] can have a lot of [PlanActionNiveauDeRealisation].

So, I put a RadGrid with all my [Actions] and in the last columns I put this :

<telerik:GridTemplateColumn UniqueName="LastNiveau" HeaderText="Niveau de réalisation" >

<ItemTemplate>

<telerik:RadRating ID="ratingBar" runat="server" Orientation="Horizontal" ItemHeight="61px"

ItemWidth="11px" CssClass="ratingClass" OnRate="ratingBar_Rate" AutoPostBack="true">

<Items>

<telerik:RadRatingItem Value="0" HoveredImageUrl="/images/Rating/Rating1/2h.png" HoveredSelectedImageUrl="/images/Rating/Rating1/2h.png"

SelectedImageUrl="/images/Rating/Rating1/2s.png" ImageUrl="/images/Rating/Rating1/2.png" ToolTip="0 %" />

<telerik:RadRatingItem Value="25" HoveredImageUrl="/images/Rating/Rating1/3h.png" HoveredSelectedImageUrl="/images/Rating/Rating1/3h.png"

SelectedImageUrl="/images/Rating/Rating1/3s.png" ImageUrl="/images/Rating/Rating1/3.png" ToolTip="25 %" />

<telerik:RadRatingItem Value="50" HoveredImageUrl="/images/Rating/Rating1/4h.png" HoveredSelectedImageUrl="/images/Rating/Rating1/4h.png"

SelectedImageUrl="/images/Rating/Rating1/4s.png" ImageUrl="/images/Rating/Rating1/4.png" ToolTip="50 %" />

<telerik:RadRatingItem Value="75" HoveredImageUrl="/images/Rating/Rating1/5h.png" HoveredSelectedImageUrl="/images/Rating/Rating1/5h.png"

SelectedImageUrl="/images/Rating/Rating1/5s.png" ImageUrl="/images/Rating/Rating1/5.png" ToolTip="75 %" />

<telerik:RadRatingItem Value="100" HoveredImageUrl="/images/Rating/Rating1/6h.png" HoveredSelectedImageUrl="/images/Rating/Rating1/6h.png"

SelectedImageUrl="/images/Rating/Rating1/6s.png" ImageUrl="/images/Rating/Rating1/6.png" ToolTip="100 %" />

</Items>

</telerik:RadRating>

</ItemTemplate>

</telerik:GridTemplateColumn>

In the ItemDataBound, I put :

protected void RGPlanAction_ItemDataBound(object sender, GridItemEventArgs e)

{

if (e.Item.ItemType == GridItemType.Item || e.Item.ItemType == GridItemType.AlternatingItem)

{

var maxLength = 50;

var dataItem = e.Item as GridDataItem;

var myPlanAction = (Model.PlanAction)e.Item.DataItem;

var myRadRating = (RadRating) dataItem["LastNiveau"].FindControl("ratingBar");

myRadRating.Attributes.Add("IdPlanAction", myPlanAction.IdPlanAction.ToString());

myRadRating.Attributes.Add("IndexRadGrid", e.Item.ItemIndex.ToString());

var ndr = myPlanAction.PlanActionNiveauDeRealisation.LastOrDefault();

if(ndr != null)

{

myRadRating.Value = ndr.NiveauDeRealisation;

}

else

{

myRadRating.Value = 0;

}

Like this, it's perfect, I have a nice RadGrid with the last [PlanActionNiveauDeRealisation] of each [action].

Just, I would like to make some sorting with this last column : [lastNiveau], but i dunno what to put in the SortExpression...

Do you have any idea?

Thank you
