<%# Eval("####") %> define text limit

Hi

I assume this is straightforward but as i have not figured yet, thought i would put up a post.

When using transformations I sometimes use the expression <%# Eval("####") %>, is there a way of setting the number of characters that are display from this field, similar to how <%# LimitLength("Some example long text", 10 , "...") %> works?

Sorry if this has been posted elsewhere, i have not come across anything.

Thanks

Gavin

RE:<%# Eval("####") %> define text limit

Hi,

You can for example use following method in your transformation code:

CMS.GlobalHelper.TextHelper.LimitLength(String, Int32, String)

public static string LimitLength(
	string text,
	int maxLength,
	string padString
)

Example:

<%# TextHelper.LimitLength(Eval("DocumentName").ToString(), 5, "...") %>

Best regards,
Miroslav Remias.

RE:<%# Eval("####") %> define text limit

Thanks Miroslav

Although having trouble trying to get it working within the transformation

<script type="text/C#" runat="server" >
CMS.GlobalHelper.TextHelper.LimitLength(String, Int32, String)

public static string LimitLength(
	string text,
	int maxLength,
	string padString
)
</script>

<%# TextHelper.LimitLength(Eval("PreText").ToString(), 5, "...") %>

Can you point out where i have gone wrong?

Thanks

Gavin

RE:<%# Eval("####") %> define text limit

Thanks Miroslav although i am still having trouble.

Have added to the current transformation that i am using and an empty one, but get the following error

"[CMSDataProperties.LoadTransformation]: http://server//CMSTransformations/54da185f-d4f9-40dc-a8a6-be1867da4f3e/custom/sowgreen/latestslider.ascx(11): error CS1501: No overload for method 'LimitLength' takes '3' arguments"

Any clues?

Thanks

Gavin


Kentico Consulting	kentico_mirekr - 10/13/2009 12:15:17 PM RE:<%# Eval("####") %> define text limit Hi, This is really strange, could you please let us know what exact version of Kentico CMS are you using and could you also please post here your transformation code (complete code). Best regards, Miroslav Remias.

RE:<%# Eval("####") %> define text limit

Thanks Miroslav

Ok seeing as this is not the norm i will put more detail...

Version is 3.1a

The document type in use is a custom one although putting the standard <%# Eval("####") %> pulls the column details from the DB ok.

Transformation is being used in the stadard 'ScrollingText' webpart - have tried both the transformation below and an empty one.


<div class="slide">
	
		<h5 class="latOrd">
			Latest Orders
		</h5>
		<div class="slidePre">

<%# Eval("PreText") %>
<!--<%# TextHelper.LimitLength(Eval("PreText").ToString(), 5, "...") %>-->
			
		</div>
		<div class="slideDate">
			Ordered: <%# Eval("Dates") %>
<br />
<a href="~/Latest-Orders.aspx">See more...</a>
		</div>

</div>
<div class="slideBott">
</div>

Hope this sheds some light?

Thanks

RE:<%# Eval("####") %> define text limit

Hi,

This explains a lot. Since you are using 3.1a version there is different number of parameters in the same function:

public static string LimitLength(
string text,
int maxLength
)

So, please use following code in your transformation:

<%# TextHelper.LimitLength(Eval("PreText").ToString(), 5 ) %>

Best regards,
Miroslav Remias.
