I managed to add line break in tooltip by adding

\n

between the text. Following is the snippet code:

WebGrid1.RootTable.Columns.GetNamedItem("CompanyName").HeaderTooltip = "This\nis my \ntext example \nof tooltip. \nThis is my text example of tooltip. This is my text example of tooltip. This is my text example of tooltip. This is my text example of tooltip. This is my text example of tooltip. This is my text example of tooltip.";

Result:

Hope this helps.
