I think you forgot to add a tooltip property to the column header.
I have tried to do the following:
column.Header.Text = string.Format("<span title=\"{0}\">{1}</span>", toolTip, column.Header.Text);
This works. I get a tooltip when I hover over the grid header. This solution has two disadvantages:
Hey Roland,
One solution would be to attach to the grid inititalize client event and set the title attribute of the columns' header elements. I tried the following code and sorting still works. The title attributes stay after sorting and a postback as well. As for the tooltip property, I'd suggest submitting a feature request on that.
function initGrid(grid, args) { var cols = grid.get_columns(); var count = cols.get_length(); for (var x = 0; x < count; ++x) { var col = cols.get_column(x); var el = col.get_headerElement(); el.title = col.get_headerText(); } }

Is this ToolTip property added in latest version? i.e 2010.2.
