I have a master details grids. I only want users be able to click on add button in the details grid when a record is selected in the master grid. How can I achieve that?
When adding a record to the child grid, I need to grab the key field from the selected row in the parent grid and add it as an extra parameter to the request url. I am using the add button and form editing out of the box.
I read in other posts that I can use getrowdata + extraparams but I couldn't find an example of how and where to use them… Any hint?
