It is relatively easy to add alternating colours to the rows in your datagrid. However, when we move the mouse over the rows we may want to highlight this row, and possibly to add the option of a click through based on the row selected. This is the basis of this article. 

As a quick refresh to set the rows to be alternating add the following parameters to the datagrid definition, between the tag definitions. <ALTERNATINGITEMSTYLE BackColor="Gainsboro" /> <ITEMSTYLE BackColor="WhiteSmoke" HorizontalAlign="Right" Font-Size="10px" Font-Names="Verdana" /> <asp:datagrid id="grdListItem" GridLines="None" runat="server" AutoGenerateColumns="False" CellPadding="4" Borderwidth="0" bordercolor="transparent"  AllowPaging="True" Visible="False">   <EDITITEMSTYLE BackColor="#EEEEEE">   </EDITITEMSTYLE>   <ALTERNATINGITEMSTYLE BackColor="Gainsboro">   </ALTERNATINGITEMSTYLE>   <ITEMSTYLE BackColor="WhiteSmoke" Font-Names="Verdana" Font-Size="10px" HorizontalAlign="Right">   </ITEMSTYLE>   <COLUMNS> Now to add the mouse effects we add OnItemDataBound="dtgMydatagrid_ItemDataBound"to the datagrid definition and supply the appropritate function. Public Sub dtgMydatagrid_ItemBound(ByVal sender As Object, ByVal e As DataGridItemEventArgs) Handles dtgMydatagrid.ItemCreated     Dim currentColour As String< BR >     If e.Item.ItemType = ListItemType.Item Ore.Item.ItemType=ListItemType.AlternatingItemOr    e.Item.ItemType=ListItemType.SelectedItemThen        e.Item.Attributes.Add("onmouseover","this.style.backgroundColor='beige';this.style.cursor='hand'")        e.Item.Attributes.Add("onclick","javascript:window.location.href='default.aspx?id=" & e.Item.Cells(0).Text & "'")     End If     If e.Item.ItemType = ListItemType.Item Then         currentColour = dtgMydatagrid.ItemStyle.BackColor.ToKnownColor.ToString         e.Item.Attributes.Add("onmouseout", "this.style.backgroundColor='" & currentColour & "'")     End If     If e.Item.ItemType = ListItemType.AlternatingItem Then         currentColour = dtgMydatagrid.AlternatingItemStyle.BackColor.ToKnownColor.ToString         e.Item.Attributes.Add("onmouseout", "this.style.backgroundColor='" & currentColour & "'")     End If End Sub
