I'm using Report Viewer, data appears normal, but a blank border appears on computers with high resolution like FULL HD for example.
Formloadingcode.
Reportproperties. 
I installed the EXE on another smaller resolution machine and the report was generated without the border. I would like to remove this border or know if it has any settings for the report to expand with resolution.
Greetings.
In my project I solved the following code:
First, create the ConfigureMargs method.
private void ConfigurarMargens()
{
// Configura as margens do relatório
System.Drawing.Printing.PageSettings pg = new System.Drawing.Printing.PageSettings();
pg.Margins.Top = 0;
pg.Margins.Bottom = 0;
pg.Margins.Left = 0;
pg.Margins.Right = 0;
pg.Landscape = false;
this.reportViewer1.SetPageSettings(pg);
this.reportViewer1.RefreshReport();
}
In the Load Event of the Form do so:
private void frmMeuForm_Load(object sender, EventArgs e)
{
this.reportViewer1.RefreshReport();
ConfigurarMargens();
}
Make sure you're using the library:
using System.Drawing;
I hope this code serves as it served me.
