We just rolled out a new MergeSettings property that can be used to remove a complete line, if this line consists of empty merge fields only.

Consider the following template segment:

The following class is our data source for the merge process:

public class Report
{
    public string name { get; set; }
    public string company { get; set; }
    public string blank { get; set; }
}

When the merge field blank is not used (is empty), an empty blank line will be rendered:

Report report = new Report()
{
    company = "Text Control, LLC",
    name = "Bjoern Meyer"
};

TXTextControl.ReportingCloud.ReportingCloud rc = 
    new TXTextControl.ReportingCloud.ReportingCloud(
        "user@domain.com", 
        "yourpassword", 
        new Uri("https://api.reporting.cloud/"));

MergeBody body = new MergeBody()
{
    MergeData = report
};

List<byte[]> documents = rc.MergeDocument(body, "RemoveEmptyLines.tx", ReturnFormat.TX);

When the removeEmptyLines property is set to true, this empty line gets removed when merging the document:

MergeBody body = new MergeBody()
{
    MergeData = report,
    MergeSettings = new MergeSettings()
    {
        RemoveEmptyLines = true
    }
};

Happy coding!
