Transformation - Eval in Repeater problem

Hi there,

I'm trying to write a custom transformation for Category List web part. For each category I want a list of items for that category. Then I'll write some JS to show/hide each category contents.

Here's my transformation:


<%# Eval("CategoryDisplayName") %><br />

<cc1:cmsdatalist WhereCondition="DocumentID IN ( SELECT DocumentID FROM CMS_DocumentCategory WHERE CategoryID = <%# Eval("CategoryID") %> )"
ID="CarriersList" runat="server" ClassNames="Savo.Career" 
TransformationName="Savo.Career.Preview"
SelectedItemTransformationName="Savo.Career.Default" RepeatDirection="Vertical"
RepeatLayout="Table" RepeatColumns="1" />

I'm getting this error:

[CMSDataProperties.LoadTransformation]: The server tag is not well formed.

The problematic part is "<%# Eval("CategoryID") %>". When I change that to a constant id it doesn't show the error anymore.

Does anybody know how to pass a dynamic parameter to the CMS control?

Thanks, Michal


Kentico Support	kentico_jurajo - 3/24/2011 3:41:56 PM RE:Transformation - Eval in Repeater problem Hi, The apostrophes and quotes are always tricky. Therefore I would like to recommend to create a custom function where you compose the where condition and then call it in the transformation like this: WhereCondition=<%# MyFunctions.WhereCond(Eval("categoryID")) %> Best regards, Juraj Ondrus

RE:Transformation - Eval in Repeater problem

Hi Juraj,

Thanks for your suggestion.

I haven't tried your solution because I've already solved the problem in a different way:


<cc1:cmsdatalist 
WhereCondition='<%# "DocumentID IN ( SELECT DocumentID FROM CMS_DocumentCategory WHERE CategoryID = " + Eval("CategoryID") + " )" %>' 
ID="CarriersList" runat="server" ClassNames="Savo.Career" TransformationName="Savo.Career.ListPreview" 
SelectedItemTransformationName="Savo.Career.Default" RepeatDirection="Vertical" RepeatLayout="Flow" DelayedLoading="true"/>

I changed my WhereCondition slightly and I had to add DelayedLoading="true". That seems to work fine.

Thanks,
Michal
