Can Write A Selector For Specific Column Of GridView

how can i write a selector for specific column of GridView ?

i want to do something on mouseover of a GridView Column. and i want to do it once.

Here is my gridview :

<asp:GridView AutoGenerateColumns="False" Width="100%" ID="grvUsers" runat="server">
<Columns>
<asp:TemplateField HeaderText="Delete">
<ItemTemplate>
<asp:Label ID="Label1" runat="server" Text='<%# eval("ID") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>

Html Output :

<table cellspacing="0" rules="all" border="1" id="grvUsers" style="width:100%;border-collapse:collapse;">
<tr>
<th scope="col">Delete</th>
</tr><tr>
<td>
<span id="grvUsers_Label1_0">23</span>
</td>
</tr>
</table>

GridView DataBound

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim dr As DataRow
Dim dt As New DataTable
dt.Columns.Add("id")
dr = dt.NewRow
dr(0) = "23"
dt.Rows.Add(dr)
grvUsers.DataSource = dt
grvUsers.DataBind()
End Sub
