When we select a row in a grid then the details of that row should be saved as property of a thing and be auto populated in a form which is displayed on selecting a row. How to implement this.

Hi Priyanshi, you could use the Selected Row(s) method of a service within the Mashup so that once you make a selection in a Grid  the data will be displayed or passed on to another entity be it a simple value display box or text input box within a form, see an e.g. below.

Note this will not "save" the selected data - this you will have to handle next by triggering a service to store that data to either an external database or a datatable

Could you share more detail on how you are binding the data? Is the Grid itself getting the data correctly? Here's a service flow from the e.g. i shared in my last post
