datagrid onEditcommand explanation

hi i am using vb.net, asp.net
i have a datagrid and i have a this code in my aspx file

VB Code:

<asp:DataGrid id="DataGrid1" 
            runat="server"  
            BorderColor="Tan" 
            BorderWidth="1px" 
            BackColor="LightGoldenrodYellow"
            CellPadding="2" 
            GridLines="None" 
            ForeColor="Black"
            onEditCommand ="Edit_command"
                                      onUpadteCommand="Update_command"
                                      onCancelCommand="Cancel_command"> 
 
<Columns>
<asp:EditCommandColumn 
ButtonType="LinkButton" 
UpdateText="Update" 
CancelText="Cancel" 
EditText="Edit"></asp:EditCommandColumn>
</Columns>

in my aspx.vb file i have this procedure

VB Code:

Public Sub DataGrid1_EditCommand(ByVal source As Object, ByVal e As System.Web.UI.WebControls.DataGridCommandEventArgs)
datagrid1.edititemindex = e.item.itemindex
    End Sub

i keep on getting this error message that onEditCommand ="Edit_command" is not a member of datagrid 1.. can someone please explain this to me.. thanks in advance...

hi just a short note to state i finally resolved the problem.... i had to add the same procedure name with the onEditCommand argument in my aspx file to my aspx.vb file ...

example for anyone to know
aspx file

VB Code:

onEditCommand ="[COLOR=Red]DataGrid1_editcommand[/COLOR]"

aspx.vb

VB Code:

Public Sub [COLOR=Red]DataGrid1_editcommand[/COLOR](ByVal source As Object, ByVal e As System.Web.UI.WebControls.DataGridCommandEventArgs) Handles DataGrid1.EditCommand
        DataGrid1.EditItemIndex = CInt(e.Item.ItemIndex)
    End Sub
