Question

How to hide complete column in dgrid (gridFromHtml) based on some run time parameter?
Lets say if the value of parameter is true I should be able to display some column and if the value is false then I should be able to hide that same column.

Answer 1

Use grid.styleColumn(columnId, css):

var grid = new Grid({
    store: store,
    columns: [
        { id: "artist", label: "Artist", field: "Artist"},
        { id: "name", label: "Song", field: "Name"},
        { id: "gerne", label: "Genre", field: "Genre"}
    ]
}, "grid-placeholder");

// to hide column with id="name"
grid.styleColumn("name", "display: none;");

// to show it
grid.styleColumn("name", "display: table-cell;");
