Create a template column in The DataGrid <Asp: TemplateColumn> <ItemTemplate> <Div onMouseOver = "MM_showHideLayers ('layer <% # DataBinder. eval (Container, "DataItem. f_ID ") %> ','', 'show') "onMouseOut =" MM_showHideLayers ('layer <% # DataBinder. eval (Container, "DataItem. f_ID ") %> ','', 'hide') "> <Font color = blue> <U> details </U> </font> </Div> <Span id = 'layer <% # DataBinder. eval (Container, "DataItem. f_ID ") %> 'style =" position: absolute; left = 420; top: 100; width: 300; z-index: 1; layer-background-color: # FFFFCC; border: 1px none #000000; visibility: hidden; "> <Table width = "100%" border = "0" cellpadding = "10" cellspacing = "1" bgcolor = "#000000"> <Tr> <Td bgcolor = "# FFFFCC"> <% # DataBinder. Eval (Container, "DataItem. f_Memo") %> </Td> </Tr> </Table> </Span> </ItemTemplate> </Asp: TemplateColumn> Include <script src = Function. js> </script> (if the JS file is in the same directory as your aspx file), f_ID in the template column above is to display the table's primary key (that is, DataKeyField in the DataGrid ), f_Memo is the information displayed when you move your mouse over "details.
