Viewer and Toolstrip

Viewer Toolbar Control

ViewerToolstrip is a WinForms control that wraps RdlViewer and provides a standard report toolbar — open, save, print, zoom, and page navigation — without requiring you to build it yourself.

Install

dotnet add package Majorsilence.Reporting.RdlViewer

Adding to a form

Wire ViewerToolstrip to an existing RdlViewer by passing the viewer to the constructor, or by assigning it to the Viewer property:

// Option A — pass viewer to constructor
var rdlViewer1 = new Majorsilence.Reporting.RdlViewer.RdlViewer();
var reportStrip = new Majorsilence.Reporting.RdlViewer.ViewerToolstrip(rdlViewer1);

// Option B — assign after construction
var rdlViewer1 = new Majorsilence.Reporting.RdlViewer.RdlViewer();
var reportStrip = new Majorsilence.Reporting.RdlViewer.ViewerToolstrip();
reportStrip.Viewer = rdlViewer1;

After creating both controls, add them to your form. Place the toolstrip above the viewer:

// In the Form constructor or designer code
this.Controls.Add(reportStrip);   // top
this.Controls.Add(rdlViewer1);    // below

reportStrip.Dock = DockStyle.Top;
rdlViewer1.Dock = DockStyle.Fill;

Full form example

public class ReportForm : Form
{
    private RdlViewer _viewer;
    private ViewerToolstrip _toolstrip;

    public ReportForm(string rdlPath)
    {
        InitializeComponent();

        _viewer   = new RdlViewer   { Dock = DockStyle.Fill };
        _toolstrip = new ViewerToolstrip(_viewer) { Dock = DockStyle.Top };

        Controls.Add(_viewer);
        Controls.Add(_toolstrip);

        Load += async (s, e) => await LoadReportAsync(rdlPath);
    }

    private async Task LoadReportAsync(string rdlPath)
    {
        RdlEngineConfig.RdlEngineConfigInit();
        await _viewer.SetSourceFile(new Uri(rdlPath));
        await _viewer.Rebuild();
    }
}

Programmatic zoom

The toolstrip reflects viewer zoom changes automatically. You can also set zoom directly on the viewer:

_viewer.Zoom = 1.5f;   // 150%
_viewer.Zoom = 0.75f;  // 75%
