Hello,

1) You can attach to the InitializeRow event of the WebDataGrid and set height the following way:

    protected void WebDataGrid1_InitializeRow(object sender, RowEventArgs e)
    {
        e.Row.Height = new Unit("50px");
    }

2) You can also set height using css by modifying the following class in the ig_dataGrid.css file:

tbody.igg_Item>tr>td {

height: 50px;

}

Please let me know if you have further questions on the matter, I will be glad to help.
