I don't think you need a extra
BoundField
for the same. You can attach the tooltip to the row inside the
RowDataBound
Event. Something like this...
protected void gvTestEscapePress_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
string course_group = "demo text";
e.Row.ToolTip = course_group;
}
}
If this does not work, you can try adding
mouseover
event like...
e.Row.Attributes.Add("onmouseover", e.Row.ToolTip = "demo text");
