Value cannot be null. Parameter name: value

[ALEX]

Hi Team,

           I'm facing this error "Value cannot be null. Parameter name: value" when i import the "docx" to richtextbox. I refer this Link for sample code. I can read below code for some file but some are not.

Here is sample Code

private void button1_Click(object sender, EventArgs e)
{
    RadDocument document = new RadDocument();
    IDocumentFormatProvider provider = new DocxFormatProvider();
    OpenFileDialog openDialog = new OpenFileDialog();
    openDialog.Filter = "Documents|*.docx";
    openDialog.Multiselect = false;
    DialogResult dialogResult = openDialog.ShowDialog();
    if (dialogResult ==  System.Windows.Forms.DialogResult.OK)
    {
        using (Stream stream = openDialog.OpenFile())
        {
            document = provider.Import(stream);
            radRichTextBox1.Document = document;
        }
    }
}

 

I do not know this is the file issue or not. I'm using V2011.3.11.1219 WinForms. I attached the file that can not read from code. You need to change the extension to docx.

 

Regards,

Hello Alex,

Thank you for writing.

Please note that the old RadRichTextBox control is now deprecated. Please upgrade to use RadRichTextEditor which has no issues opening the file.

I hope this helps. Should you have further questions please do not hesitate to write back.
