Ag-Grid Multi-line Edit with Multi Row Selection

Question

I want implement multi row edit based on the selected rows, but unfortunatlty I am unable to find any example on ag-grid documentation. Here is Plunker link where I have Multi-line checkboxes on Row groups whenever I selected the rows the selected rows become editable but the issues When II focus/edit on any one of the cell all of the other selected editable rows become normal. Is ag-grid provide this feature or is it possible in ag-grid? Thanks!

Answer 1

You can change selected rows data with cellValueChanged event. for example to make the value of column a same in selected rows ,you only need to edit 1 cell

Answer 2

You can prevent deselection using grid option suppressRowClickSelection: true Have a look at my example below https://plnkr.co/edit/1aQyW0NSpjYYPNE2?preview
