You have to implement the RowEditing event in the code behind if you wish to use the edit.

Your aspx must have the editing event defined like below

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false" onrowediting="GridView1_RowEditing">

and in your C# code,

protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
     //Your code related to editing here
}

Do you have a button column in your GridView to trigger the Edit Comand .If you have assigned a reserved key word as command name to button then you will get the error.

<asp:GridView ID="gv1" runat="server" AutoGenerateColumns="False" Width="100%" OnRowCommand="gv1_RowCommand"
            CellPadding="2">
            <Columns>
                <asp:TemplateField HeaderText="Edit">
                    <ItemTemplate>
                        <asp:Button ID="Button2" runat="server" Text="Edit" CommandName="EDIT" CommandArgument="<%# Bind("ID") %>" />
                    </ItemTemplate>
                </asp:TemplateField>
                <%--Your other column Here--%>
            </Columns>
        </asp:GridView>

In above code CommandName is assigned a keyword "Edit".

You should change it to "EditItem" or something like that.

Updated Code:

  <asp:GridView ID="gv1" runat="server" AutoGenerateColumns="False" Width="100%" OnRowCommand="gv1_RowCommand"
            CellPadding="2">
            <Columns>
                <asp:TemplateField HeaderText="Edit">
                    <ItemTemplate>
                        <asp:Button ID="Button2" runat="server" Text="Edit" CommandName="EDITITEM" CommandArgument="<%# Bind("ID") %>" />
                    </ItemTemplate>
                </asp:TemplateField>
                <%--Your other column Here--%>
            </Columns>
        </asp:GridView>
