Hello everyone,

How can I solve this error?

I have tried,

private void PrintImageHandler(object sender, PrintPageEventArgs ppeArgs)
{
string[] ListViewItemsData = ListViewItemsCollections.Select(i => Convert.ToString(i.FilePath) + Convert.ToString(i.Parent_File_Name) + "_" + Convert.ToString(i.Child_File_Name)).ToArray();
List images = new List();
foreach (var file in ListViewItemsData)
{
images.Add(new Bitmap(file));
}
if (images != null)
{
ppeArgs.Graphics.DrawImageUnscaled(images, 0, 0);
}
ppeArgs.HasMorePages = (images != null);
}

Please help me.

Hello Chetan,

I have changed the code as you say,

Inside button click,
try
                    {
                        PrintDocument pd = new PrintDocument();
                        pd.PrintPage += new PrintPageEventHandler(PrintImageHandler);
                        System.Windows.Forms.PrintDialog pdi = new System.Windows.Forms.PrintDialog();
                        pdi.Document = pd;
                        if (pdi.ShowDialog() == System.Windows.Forms.DialogResult.OK)
                        {
   pd.Print();
}
                        else
                        {
                            MessageBox.Show("Print Cancelled");
                        }
                    }


After calling,
private void PrintImageHandler(object sender, PrintPageEventArgs ppeArgs)
        {
string[] ListViewItemsData = ListViewItemsCollections.Select(i => Convert.ToString(i.FilePath) + Convert.ToString(i.Parent_File_Name) + "_" + Convert.ToString(i.Child_File_Name)).ToArray();

            List images = new List();
            foreach (var file in ListViewItemsData)
            {
                images.Add(new Bitmap(file));
            }

            if (images != null)
            {
                foreach (System.Drawing.Image img in images)
                {
                    ppeArgs.Graphics.DrawImageUnscaled(img, 0, 0);
                }
            }
            ppeArgs.HasMorePages = (images != null);
}
But the problem loop is not ending... How can I solve that? I have only two in the ListViewItemsData

DrawImageUnscaled method expe c ta only one image as first argument but you are passing list of images. You can loop thru images list using foreach and call that method for each of the image in the list.
