You will need to create classes for each of the different row types to your CSS file in your theme. Then, following the documentation for this widget in the appstore, place the datagrid in a table and in the next row of the table, place the widget. Then open up the properties window of the widget, click on the Rows tab, define that attribute which will determine the styling to be used and define which classes are tied to which attribute value.
hope that helps.
Hi Osbert,
There is a good demo project, this will give some help https://github.com/Andries-Smit/DataGridExtention/tree/master/Test
I have tried to use the data grid extension widget on a project, but the page that contains it, is extremely slow at loading. Any ideas on that?
