Question about Loading from XML

m_lyons · February 2017

Hi everyone. I'm trying to load a report from an XML file, and I keep getting the below errors:

Here is my code:

//Create Dataset
DataSet EstimateDS = new DataSet();
EstimateDS.ReadXml(Environment.CurrentDirectory + "//EstimateSample3.xml");

FastReport.Report report = new FastReport.Report();

//Use if designing report
report.SetParameterValue("FullPathNameOfPictureFile", fullpathname);
report.RegisterData(EstimateDS, "Data");
report.GetDataSource("Data").Enabled = true;
report.Design(true);

At the report.GetDataSource("Data").Enabled = true; line, I am getting an error that "The object is not set to an instance of an object"

There is a Data parent node that holds all of my data.

If I save the xml to a file and attach it as a datasource manually through the report designer, it finds all of my data without an issue. So I'm not sure what I'm doing wrong here.

Thanks Again!

I just wanted to post back on this to say that I think I have it working.

I changed my code to use this method of adding the DataSource instead and this works much better for XML.

foreach (DataSourceBase source in report.Dictionary.DataSources)
{
source.Enabled = true;
}

Thanks Again!

report.registerdata is case sensitive, referring to https://msdn.microsoft.com/en-us/library/ekw4dh3f.aspx

give me the same error if i use a code like this:

using (DataSet ds = new DataSet())
Â Â Â Â Â Â Â Â Â Â Â Â {
Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â ds.ReadXml(@"d:\data.xml");
Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â using (FastReport.Report report = new FastReport.Report())
Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â {
Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â //authors != Authors
Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â report.RegisterData(ds, "Authors");
Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â report.GetDataSource("Authors").Enabled = true;
Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â report.Design(true);
Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â }
Â Â Â Â Â Â Â Â Â Â Â Â }
