read xfa using sdk

[joejoe]

I noticed the announcement that the viewer now support xfa forms. I am wondering if the sdk can read and write data to xfa forms. Does any of the sdks have the ability to programatically read and/or filf xfa fields in pdf documents?

Hi, joejoe.

You may get/set values for XFA-form fields by Java-Script also (we talking about PDF-XChange Viewer ActiveX SDK only).
Simple example (pseudocode):

Code: Select all

// get existing form field value:
string js = "var f = this.getField("Text2"); if (f != null) { f.value; };");
string res;
viewerCtrl.RunJavaScript(js, out res, 0, 0); // look to 'res' after call 
// set new value:
string js = "var f = this.getField("Text2"); if (f != null) { f.value = "myNewValue"; };");
viewerCtrl.RunJavaScript(js, NULL, 0, 0);
