Confirmation during a datagrid column deletion. (e

Hey guys... I need some help with Datagrid. My question is on setting a confirmation during a datagrid column deletion. Everything works great, not until I added a code that triggers the delete confirmation bmessage box. I am using Visual Studio.net as my tool. I found a good article on this site and I tailored my vode based upon that reference. (http://www.csharpfriends.com/Articles/getArticle.aspx?articleID=228&page=2). In fact I notice that this error(error CS0117) occurs whenever I add a new declaration on the Datagrid, in this case, when I added [OnItemDataBound="myDataGrid_OnItemDataBound"] ANY HELP ON THIS IS GREATLY APPRECIATED... Below are the details of my problem. Error message: [Compiler Error Message: CS0117: 'ASP.school_name_aspx' does not contain a definition for 'myDataGrid_OnItemDataBound'] The problem occurs in this specific area at my Datagrid declaration (OnItemDataBound="myDataGrid_OnItemDataBound") ---------------------------------------------------------------------------------------------- <asp:datagrid id="DataGrid2" runat="server" DataKeyField="ID" CellPadding="3" BackColor="White" BorderWidth="1px" BorderStyle="None" BorderColor="#CCCCCC" AutoGenerateColumns="False" OnItemDataBound="myDataGrid_OnItemDataBound"> . . . . . . . . . this is the link button(contain in the Datagrid above) that I want to set up a confirmation message box.... <asp:linkbutton id="DeleteLink" runat="server" text="Delete" commandname="Delete" /> --------------------------------------------------------------------------- I added this function on the behind-code ---------------------------------------- private void myDataGrid_OnItemDataBound(object sender, DataGridItemEventArgs e) { if(e.Item.FindControl("DeleteLink") != null) { ((LinkButton) e.Item.FindControl("DeleteLink")).Attributes.Add("onClick", "return confirm('Are you sure you wish to delete this item?');"); } } Datagrid code on school-name.aspx --------------------------------- asp:datagrid id="DataGrid2" runat="server" DataKeyField="ID" CellPadding="3" BackColor="White" BorderWidth="1px" BorderStyle="None" BorderColor="#CCCCCC" AutoGenerateColumns="False" OnItemDataBound="myDataGrid_OnItemDataBound">  <SelectedItemStyle Font-Bold="True" ForeColor="White" BackColor="#669999"></SelectedItemStyle> <ItemStyle ForeColor="#000066"></ItemStyle> <HeaderStyle Font-Bold="True" ForeColor="White" BackColor="#006699"></HeaderStyle> <FooterStyle ForeColor="#000066" BackColor="White"></FooterStyle> <Columns> <asp:TemplateColumn> <ItemTemplate>  <asp:linkbutton id="DeleteLink" runat="server" text="Delete" commandname="Delete" /> </ItemTemplate> </asp:TemplateColumn> <asp:BoundColumn DataField="ID" ReadOnly="True" HeaderText="ID"></asp:BoundColumn> <asp:EditCommandColumn ButtonType="LinkButton" UpdateText="Update" CancelText="Cancel" EditText="Edit"></asp:EditCommandColumn> <asp:TemplateColumn HeaderText="Name"> <ItemTemplate> <%#DataBinder.Eval(Container.DataItem, "name" )%> </ItemTemplate> <EditItemTemplate> <asp:TextBox ID="txtName" Text='<%#DataBinder.Eval(Container.DataItem, "name" )%>' Size="40" runat="server" MaxLength="100"/> <asp:RequiredFieldValidator ControlToValidate="txtName" Text="*" Runat="server" ErrorMessage="'School Name' field is required!" /> </EditItemTemplate> </asp:TemplateColumn> <asp:TemplateColumn HeaderText="Year Start"> <ItemTemplate> <%#DataBinder.Eval(Container.DataItem, "year_start" )%> </ItemTemplate> <EditItemTemplate> <asp:TextBox ID="txtYearStart" Text='<%#DataBinder.Eval(Container.DataItem, "year_start" )%>' Size="4" runat="server" MaxLength="4" /> <asp:RequiredFieldValidator ControlToValidate="txtYearStart" Text="*" Runat="server" ID="Requiredfieldvalidator1" ErrorMessage="'Year Start' field is required!

STUPID ME.....

.. It is a sort of 'not compiling correctly' .. What happen was I have duplicate copy of the same file in the same project(I'm using VStudio) but with different name. I guess ASP.net is confused on these duplicate copy. What I did was, I completely delete that other duplicate copy. Then I had another problem... on Datagrid not able to access the "myDataGrid_OnItemDataBound" funtion. I solve the problem by changing the function attribute to public instead of private.. VOILA' SOLVE THE PROBLEM!!!!!!!!!!!!! THANKS FOR YOUR COMMENTSSSSSS
