Kentico Developer	kentico_helenag - 4/28/2009 5:56:07 AM RE:Help me please (Transformation) Hi, you could use the IfCompare function.

RE:Help me please (Transformation)

I tried to use the IfCompare but I am getting an error. Here is the code snippet:

<%# IfCompare(Eval("HolidayHoursActive"),"True","","<tr><td><strong>Holiday Hours:</strong></td><td>" + Eval("HolidayHours") + "</td></tr>") %>

The error says: [CMSAbstractTransformation.DataBind]: Unable to cast object of type 'System.Boolean' to type 'System.String'.


Member	rebecca.wells - 7/14/2009 1:23:01 PM RE:Help me please (Transformation) Nevermind... with some trial and error I found that if I changed the "True" to 0 (zero), then the statement works.

RE:Help me please (Transformation)

Hello,

I have the similar problem with IfCompare method...the method works fine if it has to present a link, for example.

But if the return value is True, I would like to generate a piece of code which contains my custom control. Is that possible to do somehow? I also must say that my control is registered, and when I use it outside IfCompare method it works perfectly.

The code I use, and that doesn't work is the following:

<%# IfCompare(Eval("Free"), "Free", "", "<uc1:MyControl id=\"" + Eval("FName") + "\" runat=\"server\"  />") %>

When I checked it using FireBug, I saw that this method didn't load my control.


Member	rebecca.wells - 7/27/2009 12:08:46 PM RE:Help me please (Transformation) I'm no expert, by maybe you could try changing it like this: IfCompare(Eval("Free"), "True", ""


Member	rebecca.wells - 7/27/2009 12:10:25 PM RE:Help me please (Transformation) Du'oh! Didn't even follow my own earlier advice (use a 0 instead of True). Change it to this IfCompare(Eval("Free"), "0", ""

RE:Help me please (Transformation)

Hi Rebecca,

thanks for replying.

My field "Free" is string, and when I put the compare value it is working fine, and checking the condition.

For example, if the method returns "true", it is working fine and it writes the following code:

<a href="www.google.com>Google</a>

But if I put my user control instead of the <a> tag, it doesn't load the user control.

RE:Help me please (Transformation)

Hi Jagr,

Please do not use the control specification inside the IfCompare function. You could for example add your control directly in the transformation and use the condition in Visibility property of your control so that you can hide/show the control according your needs.

Are there any problems with this solution?

Best regards,
Helena Grulichova
