FR: default value of grouping specified at generation time about reportgenerator

[danielpalme]

I'm sorry, but that's a very specific requirement.
You should use a custom report.

This would be the easiest way to solve your problem:

using System;
using System.Collections.Generic;
using System.Linq;
using System.IO;
using System.Text;
using Palmmedia.ReportGenerator.Parser.Analysis;
using Palmmedia.ReportGenerator.Properties;
using Palmmedia.ReportGenerator.Reporting;
using Palmmedia.ReportGenerator.Reporting.Rendering;

namespace MyCompany.CustomReportTypes
{
    [System.ComponentModel.Composition.Export(typeof(IReportBuilder))]
    public class CustomHtmlReportBuilder : HtmlReportBuilder
    {
        public override void CreateSummaryReport(SummaryResult summaryResult)
        {
            base.CreateSummaryReport(summaryResult);

            string javascriptPath = Path.Combine(this.TargetDirectory, "combined.js");

            string content = File.ReadAllText(javascriptPath)
                .Replace("grouping: '0',", "grouping: this.getGroupingMaximum(this.props.assemblies),");

            File.WriteAllText(javascriptPath, content);
        }
    }
}

Thank you I will give this a try.

The final solution that I went with is working great with this code for a plugin:

using System;
using System.Collections.Generic;
using System.Linq;
using System.IO;
using System.Text;
using Palmmedia.ReportGenerator.Parser.Analysis;
using Palmmedia.ReportGenerator.Properties;
using Palmmedia.ReportGenerator.Reporting;
using Palmmedia.ReportGenerator.Reporting.Rendering;

namespace MyCompany.CustomReportTypes
{
    [System.ComponentModel.Composition.Export(typeof(IReportBuilder))]
    public class ComponentExpandedReportBuilder : HtmlReportBuilder
    {
        public override void CreateSummaryReport(SummaryResult summaryResult)
        {
            base.CreateSummaryReport(summaryResult);

            string javascriptPath = Path.Combine(this.TargetDirectory, "combined.js");

            string content = File.ReadAllText(javascriptPath)
                .Replace("getInitialState: function () {", "getInitialState: function () { var maxGroup = this.getGroupingMaximum(this.props.assemblies);")
                .Replace("grouping: '0',", "grouping: maxGroup,")
                .Replace("groupingMaximum: this.getGroupingMaximum(this.props.assemblies)", "groupingMaximum: maxGroup")
                .Replace("assemblies: this.getAssemblies(this.props.assemblies, '0', '', 'name', 'asc')",
                "assemblies: this.getAssemblies(this.props.assemblies, maxGroup, '', 'name', 'asc')");

            File.WriteAllText(javascriptPath, content);
        }
    }
}

thanks for the suggestion on this. It doesn't work. I can see that it properly sets the initial value of the grouping variable in the js. And the page does come up with that value as the value for grouping. But the initialization of the page doesn't respect the variable so the result is that I have to switch the grouping to something else, the come back to the max value.

I am going to look through the code to see if I can fix the issue where the page init doesn't respect the initial grouping value.

Found the problem. The function needs to be changed in two locations:

        return {
            grouping: this.getGroupingMaximum(this.props.assemblies),
            groupingMaximum: this.getGroupingMaximum(this.props.assemblies),
            filter: '',
            sortby: 'name',
            sortorder: 'asc',
            assemblies: this.getAssemblies(this.props.assemblies, '0', '', 'name', 'asc')
        };

The call to getAssemblies needs to have the '0' changed to "this.getGroupingMaximum(this.props.assemblies)" as well.

Recording this here incase it helps somebody else in the futrue.
