RE:conditional statement in transformation

you can use static class/function in transformation, just put it in APP_CODE

public static class MyFunctions
{
    public static string WriteURLLink(object url, object name)
    {
        if(url.ToString() == "")
            return name.ToString();
        else
            return "<A href=\"" + url.ToString() + "\">" + name.ToString() +"</A>";
    }
}

RE:conditional statement in transformation

Hi,

Could you please describe in more detail what are you trying to achieve.

Would it be possible to post here your WriteURLLink method?

Please find more information about creating custom function in transformation at Developers guide
http://devnet.kentico.com/docs/devguide/index.html?adding_custom_functions_to_transformations.htm

Best regards,

RE:conditional statement in transformation

Transformation:

<%@ Register TagPrefix="cms" TagName="Media" Src="~/CMSInlineControls/MediaControl.ascx" %>

showing the media image tag here:

<%# MyFunctions.GetMediaImgTagOnly(Eval<string>("Photo"), "about-peopleImage") %>

Functions:

private static readonly string MySiteCodeName = "/MyCmsSite";

/// <see cref="http://devnet.kentico.com/Forums/f45/t16108/Media-Selection-Url-Issue.aspx"/>
public static string GetMediaUrl(object txtValue)
    {
        string aliasRemovedUrl = String.Empty;
        if (!(txtValue == null | txtValue == DBNull.Value))
        {
            aliasRemovedUrl = txtValue.ToString().Replace(MySiteCodeName, "~");
        }

        return aliasRemovedUrl;
    }

    /// <see cref="http://devnet.kentico.com/Forums/f45/t16228/conditional-statement-in-transformation.aspx"/>
public static string GetMediaImgTagOnly(object txtImage, object cssClass)
    {
        string mediaImgTag = String.Empty;
        if (!(txtImage == null | txtImage == DBNull.Value | String.IsNullOrEmpty(txtImage.ToString())))
        {
            //work with the image
            mediaImgTag = "<cms:Media id=\"mediaImageID\" runat=\"server\"";
            if (!(cssClass == null | cssClass == DBNull.Value | String.IsNullOrEmpty(cssClass.ToString())))
            {
                mediaImgTag += " class=\"" + cssClass + "\"";
            }
            mediaImgTag += " Url=\"" + GetMediaUrl(txtImage) + "\" />";
        }
        return mediaImgTag;
    }

RE:conditional statement in transformation

Hi,

have you found a solution to this issue?

Also, have you tried to verify if the result of Eval method is correctly passed to your custom function?
There could be a limitation that the methods and their parameters were resolved at the same time, causing the wrong parameter being passed into the custom function.

Thank you in advance for information.

Regards,
Zdenek
