I've created some new pages and have only put your components on that page so there cannot be any problem with code causing a problem. I took the entire Excel Sample and copied the exact code EXCEPT I remove the data source. The entire toolbar is blank. In my package.json file I'm using
"dependencies": {
"@syncfusion/ej2-vue-grids": "^17.1.42",
"@syncfusion/ej2-vue-pdfviewer": "^17.1.43",
"@syncfusion/ej2-vue-popups": "^17.1.42",
and I'm using a trial download-- could there be problems with different versions?
Thanks
