How do I make an iframe show at 100%?-CodePudding

I am trying to follow along with

What am I doing wrong?

CodePudding user response：

iframe height only allows height=pixels so 100%=minimum (default=150)

see

But simplest is decide a desired height. Workarounds may not work well based on user settings

CodePudding user response：

Probably just invalid or at least not well-formatted HTML string. I'd suggest using the XElement syntax to build the HTML output, it helps to write the tags and attributes correctly...

Dim pdfBytes = 'The PDF byte array...
Dim pdfBase64 = Convert.ToBase64String(pdfBytes)
Dim html =
    <html>
        <body>
            <iframe
                width="100%"
                height="100%"
                src=<%= String.Concat("data:application/pdf;base64,", pdfBase64) %>>
            </iframe>
        </body>
    </html>.ToString()

WebView21.NavigateToString(html)

Nice VB.NET feature.

can you try height="auto"; what is your parent div's height?
