Re: DataView and DataView Tree Levure Helpers
Thanks very much for your clear reply Trevor. And i'd like to thank you for your great contributions. Given the fact we can always "roll back" , i can give it a try on a project and see how it goes. I was especially interested in the Dataview as perhaps it is faster and may scroll smoother than the DG2. Have a good weekend !

Curious about some things. Can this dataview do the same things as the datagrid? Like Form with images and fields on a row via row template or similar?

DataView and DataView Tree Levure Helpers
Hi folks, Over the holiday break I took time to package up some UI controls I use in my own projects and make them available as helpers for Levure apps*. The controls are named "DataView" and "DataView Tree". The DataView is a leaner, more efficient DataGrid Form. It allows you to efficiently display highly customized rows of data on desktop and mobile. The DataGrid Tree is built on top of the DataView and works with a tree structure. I've prepared a demo project with examples of each type of control. Here are the github repos for the demo project and the controls themselves. Demo Github repo: https://github.com/trevordevore/dataview_demo DataView Github repo: https://github.com/trevordevore/levurehelper-dataview DataView Tree Github repo: https://github.com/trevordevore/levurehelper-dataview_tree I have also posted a video which walks through the demo project: https://youtu.be/euIHj1Qrokk While there is still work to do on the documentation, the demo stack can help the motivated developer start using the controls in their own projects. * Of course the code will work in apps that don't use the Levure framework. You just need to integrate all of the stacks and scripts into your app manually. -- Trevor DeVore ScreenSteps www.screensteps.com ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
