每当选中复选框时，如何获取插入的日期？

Question

I have this on markup:

 <asp:TemplateField HeaderText="Date Printed">
   <ItemTemplate>
    <asp:Label ID="lblMessage" style ="font-weight:bold; " runat="server" CssClass="style26"></asp:Label>
   </ItemTemplate> 
  </asp:TemplateField>

Then this code behind

For Each r As GridViewRow In gridView1.Rows
 If CType(r.Cells(0).FindControl("myrec"), CheckBox).Checked Then
   lblMessaget.Text = DateTime.Now.ToString("dd/MM/yyyy")
 End If
 Next

All I am really trying to do is whenever a user clicks a checkbox to check it and clicks the Print Checked Item box, today's date is inserted into the Date Printed column of the row of the checked box.

I am doing something stupid and that's why this is not working.

Any help is greatly appreciated.

Although I am trying to do this with vb.net or c#, if anyone can help me do it with JavaScript, that would be great also.

   <script type="text/javascript">
        function CheckBox_Click() {
            $('#' + '<%=gridView1.ClientID %>' + ' tr:has(:checkbox:checked)  td:nth-child(3) span').each(function () {
                $(this).attr("innerHTML", new Date());
            });

        }

</script>

i think you need to make sure you have the right label. lblMessaget is always assigned, but you say:

...date is inserted into the Date Printed column of the row of the checked box.

So you also need:

CType(r.Cells(0).FindControl("row-specific-label"), Label).Text = DateTime.Now.ToString( "dd.MM.yyyy" );

// Edit:

You need to make sure that you use the right index for the cell. You need the cell of the label whatever this is.
