Custom Cell Type Popup Control?

Question

Hi, I was wondering if it's possible to show a popup (a custom control populated with a small grid) on clicking on a cell. I'm trying to replicate this functionality shown in this screenshot:

Will a custom dropdown cell type work?

Thanks,

Alan

Hi Alan,We are little unclear about your requirement. We are having
the GridMultiColumnDropDownList support in SfDataGrid, Please refer the below
UG for more details. Are you looking for same thing to achieve in the
GridControl, if not please provide more details about your requirement which
will be helpful for us to provide a prompt and timely solution.Ug: https://help.syncfusion.com/wpf/datagrid/column-types#gridmulticolumndropdownlistRegard,Sampath Narayanan.S

Hi Sampath,Yes I see the SfDataGrid supports a column type of GridMultiColumnDropDownList, however we are using the GridControl control and that is not an available choice.  Looks like GridControl has support for different cell types; can the DropdownList cell type work for multi-column custom cell types?  What we're looking for is a multi-column dropdown list cell type that contains custom cell types such as dropdowns.Thanks,Alan

Hi Alan, 
 
Yes, it is possible by creating custom DropDown cell renderer with SfMultiColumnDropDown control and we have created a demo with your requirement. Please make use of the attached sample.

Hi Arulpriya,Thanks for the sample.  In the application if I click in any of the cells in the dropdown the dropdown goes away and the GridControl cell takes its value the first cell of the row I clicked on.  Is there a way to make the cells within the dropdown editable?  For example I want to check the box IsHighlighted for the Water lilies row. I would like the dropdown to stay visible when making such changes, and then go away when I click outside the dropdown.Thanks,Alan
