关于一刷新就执行ROWCOMMAND的问题
今天做东西的时候碰到一个奇怪的问题解决不了，希望高手指教一下~下面的程序，执行的时候，点击按钮的时候GridViewDetail_RowCommand会正常执行，但是执行完了之后我按F5刷新页面，跟踪过去会把GridViewDetail_RowCommand再执行一遍，就是说按F5刷新就会把最近的一次删除或者新增操作再执行一遍。
前台代码如下，继承的母版，但是母版里面没有任何函数：
<asp:GridView ID="GridViewDetail" runat="server" AllowPaging="true" PageSize="20"
ShowFooter="true" AutoGenerateColumns="False" OnPageIndexChanging="GridViewDetail_PageIndexChanging"
OnRowCommand="GridViewDetail_RowCommand" OnRowDataBound="GridViewDetail_RowDataBound">
<Columns>
<asp:TemplateField HeaderText="Sort">
<ItemTemplate>
<asp:Label ID="LabelSort" runat="server" Text='<%# Server.HtmlEncode(Eval("Sort").ToString()) %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="PicName">
<ItemTemplate>
<asp:Label ID="LabelPicName" runat="server" Text='<%# Server.HtmlEncode(Eval("AdsTitle").ToString()) %>'></asp:Label>
</ItemTemplate>
<FooterTemplate>
<asp:TextBox ID="TextBoxAddPicName" runat="server" style="width: 140px; height: 15px"></asp:TextBox>
</FooterTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="UploadImage">
<ItemTemplate>
<asp:Label ID="LabelUploadImage" runat="server" Text='<%# Server.HtmlEncode(Eval("ImgPath").ToString()) %>'></asp:Label>
</ItemTemplate>
<FooterTemplate>
<asp:FileUpload ID="FileUploadImage" runat="server" style="width: 140px; height: 20px"/>
</FooterTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="GoodsLink">
<ItemTemplate>
<asp:Label ID="LabelGoodsLink" runat="server" Text='<%# Server.HtmlEncode(Eval("GoodsID").ToString()) %>'></asp:Label>
</ItemTemplate>
<FooterTemplate>
<asp:DropDownList ID="DropDownListGoodsLink" runat="server" style="width: 140px; height: 15px">
</asp:DropDownList>
</FooterTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Delete">
<ItemTemplate>
<%-- <asp:ImageButton ID="ImageButtonDelete" runat="server" CommandName="Del" ImageUrl="../pics/delete.gif" CommandArgument='<%# Server.HtmlEncode(Eval("AdsID").ToString()) %>'/>--%>
<asp:Button ID="Button2" runat="server" Text="Button" CommandName="Del" CommandArgument='<%# Server.HtmlEncode(Eval("AdsID").ToString()) %>'/>
</ItemTemplate>
<FooterTemplate>
<%-- <asp:ImageButton ID="ImageButtonAdd" runat="server" CommandName="Insert" ImageUrl="../pics/add.gif" />--%>
<asp:Button ID="Button1" runat="server" Text="Button" CommandName="Add"/>
</FooterTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>

}
