Binding PageBreak Property

[Keith Knight]

From the property window in the designer, I am attempting to set the Binding expression for PageBreak based on the existing of a databound field.

I would expect that it is something like:
PageBreak = !string.IsNullOrEmptyOrWhitespace(Field.MyTextField) ? PageBreak.Before : PageBreak.None;

Can this be done without writing actual code behind on the report?

Hello Keith Knight,

When Bindings are used the expression should be evaluated to an object of type appropriate for the target property. In case of PageBreak you will need an user functions to perform appropriate type conversions. Check out the following code snippet and sample binding:

public static PageBreak ConvertPageBreak(string pageBreak)
{
    if (string.Equals(pageBreak, "before", StringComparison.InvariantCultureIgnoreCase))
    {
        return PageBreak.Before;
    }
    return PageBreak.None;
}

Once you add the user function and build the project, you can utilize it in multiple expressions without any further coding.

Property path	Expression
PageBreak	=IIF(Fields.MyTextField is null OR Fields.MyTextField="", ConvertPageBreak("none"), ConvertPageBreak("before"))

Kind regards,
