Hi,
To populate FlexGrid from JSON fetched from external URL, all you have to do is first assign an empty collectionView to the FlexGrid’s itemSource and then after fetching the data assign fetched data to the collectionView’s sourceCollection and it will be loaded into the grid.
Please refer to the following sample: https://stackblitz.com/edit/js-b5h2ts?file=index.js
Note: Wijmo’s FlexGrid is a JavaScript client-side control, I am not sure how you are going to use this in SilverLight application. We have a SilverLight version of FlexGrid, but there is no active support on it.
Let me know if you need some more assistance.
Regards
Sharad
