c# wait for LoadFromFile()

[f00bar]

Hello,
can I wait for DocDocumentViewer to load document from file? I'm working on these three steps to programmatically print with/withnout user interaction:

1) Programmatically load document:

Code: Select all

this.docDocumentViewer.LoadFromFile("tmp.docx");

2) Wait until document is loaded, or fire event when it's loaded.


3) Programmatically print document:

Code: Select all

this.customizeToolBar.DialogPrint();
this.customizeToolBar.SilentPrint();

Also I'd like to hide form and show only print dialog.

Thanks for any hints.

Hi f00bar,

Thanks for your post.
Spire.DocViewer has provided a document loaded event "DocLoaded". You could do the printing in this event to accomplish your task. In addition, the property "Visible " is for hiding the viewer form. Please refer to the code below.

Code: Select all

private void button1_Click(object sender, EventArgs e)
{
    //Hide the viewer form
    this.docDocumentViewer1.Visible = false;
    //Load file
    this.docDocumentViewer1.LoadFromFile("tmp.docx");
    //Print in the DocLoaed event
    this.docDocumentViewer1.DocLoaded += docDocumentViewer1_DocLoaded;
}

private void docDocumentViewer1_DocLoaded(object sender, EventArgs args)
{
    //MessageBox.Show("File Loaded!");
    //Silent print
    this.docDocumentViewer1.PrintDocument.PrintController = new StandardPrintController();
    this.docDocumentViewer1.PrintDocument.Print();
}
