How to get selected rows from grid

Hi Frank,

a) Is it possible to add a checkbox column to the grid by which individual rows can be checked/unchecked?

It is possible to put a checkbox. Here are a few forum threads that show how:

b) How can I get access to the selected row or rows f.e. by clicking a button "Get rows" outside the grid? If it will not work with multiple checked rows, is there a way to get the selected (highlited) row?

You can use the Value property of the DataGrid component. Set it to a page property. The DataGrid will store all selected data items in that property as an array.

c) In the northwind demo I have seen that links in a row can be implemted (see screenshot). How can this be accomplished?

This is implemented by using the Template of the DataGrid column. It can contain other components such as the Link. Here is how it looks in the Northwind demo.

Here are some instructions that show how to use the Template to customize the appearance of DataGrid columns.
