Hi Francesco,

Thank you for posting this request!

The described behavior appears because the heights of the rows are automatically adjusted depending on the content of the visible cells.

Currently, you can overcome this behavior by setting the height of the row elements explicitly so they do not change automatically:

    <Scrolling ... />
    <ClientEvents OnGridCreated="gridCreated" />
function gridCreated(sender, args) {
    var grid = sender;

//get the header item and set its height
    var HasStaticHeaders = grid.ClientSettings.Scrolling && grid.ClientSettings.Scrolling.UseStaticHeaders;
    var headerRow = HasStaticHeaders ? grid.GridHeaderDiv.querySelector("thead > tr") : grid.get_masterTableView().HeaderRow;

    headerRow.style.height = headerRow.offsetHeight + "px";

//loop through the data items and set height to each of them
    var dataItems = grid.get_masterTableView().get_dataItems();
    var currentItem;

    for (var i = 0; i < dataItems.length; i++) {
        currentItem = dataItems[i].get_element();
        currentItem.style.height = currentItem.offsetHeight + "px";

Alternative options to avoid unwanted resizing are:

  1. Display all text on a single line.
  2. Display the beginning portion of the text on a single line + "...", then put the entire text to the Tooltip of the cell.
  3. Set some static height to all of the items:
    <ItemStyle Height="50px" />
    <AlternatingItemStyle Height="50px" />
