jqxgrid contextmenu Posts

Hi there,

I need to add a contextmenu to my grid. Basically what i need is: The user right cliks a row, the row gets selected and the menu is shown for that row. I can’t manage to do this. How can i detect a right click on a grid row?

Thanks,

Daniel Teixeira

Hi Daniel,

Rows are selected only on left click. If you need to select a row on right click, you need to use the ‘selectrow’ method.

The following sample code opens a Context Menu and Selects a Row when the user right clicks on a grid row.
