Unlock the Potential: Leverage Kendo Grid jQuery's Brilliant Feature - Reveal Hidden Column

Presently, the grouped columns are concealed using the attributes of the k-group-indicator element field.

 $("div.k-group-indicator").each(function (i, v) {
     grid.hideColumn($(v).data("field"));
 });

However, I am now faced with the task of making these hidden columns visible again when they are ungrouped. Unfortunately, I cannot utilize the same method for this purpose because I also provide the option for users to hide and show columns, while saving their preferences in localStorage and applying them upon returning to the page.

So, my query is whether there exists an event that I can employ, such as OnUngroup(), which would allow me to capture instances when the grid is ungrouped and subsequently make the corresponding column visible by utilizing its field name?

Answer №1

You can subscribe to a group event and check the length of the groups:

function checkGroups(e) {
  if (e.groups.length == 0) {
    alert('No groups found!');
  }
}

To make a column visible again, use this function:

function showColumn() {
  grid.showColumn();
}

Note:

The e.groups collection contains information about columns that are currently being grouped. You can save the grouping ids in localStorage or a global variable and compare them every time the group event is triggered.
