RegisterClientScriptBlock - confirm box 返回一个布尔值给 aspx.cs

RegisterClientScriptBlock - confirm box return a boolean to aspx.cs

我正在尝试在执行命令之前执行确认框。我需要从javascript消息框获取.cs（asp.net/c#）代码的响应。

这是我的代码 

 bool ReturnValue() {
    return false;
 }
  protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e) {
     string commandname = e.CommandName;
     if (commandname.Equals("atender")) {
        ClientScriptManager CSM = Page.ClientScript;
        if (!ReturnValue()) {
            string strconfirm = "<script>if(!window.confirm('Are you sure?')){ I need a code here to return a false boolean to my c#}</script>";
            CSM.RegisterClientScriptBlock(this.GetType(), "Confirm", strconfirm, false);
        }
 // There is the code which I want to not execute if the confirmation is false
}


 EDIT:

我的网格视图代码： 

 <asp:GridView  ID="GridView1" runat="server" CellPadding="4" 
        BorderStyle="None" BorderWidth="0px" CellSpacing="1" Width="100%" 
            GridLines="Vertical" AllowPaging="True" onrowcommand="GridView1_RowCommand" 
            onselectedindexchanged="GridView1_SelectedIndexChanged" 
            onpageindexchanging="GridView1_PageIndexChanging" 
            onrowdatabound="GridView1_RowDataBound" PageSize="5" HorizontalAlign=Left
            >
                            <PagerStyle HorizontalAlign="Center" />
                            <RowStyle CssClass="tabela_texto2" HorizontalAlign="Center" 
                                VerticalAlign="Middle" />
                <AlternatingRowStyle CssClass="tabela_texto1" />
        <Columns>
            <asp:ButtonField ControlStyle-CssClass="botonTransaccional" Text="Status" CommandName="atender" ButtonType="Button" />
            <asp:ButtonField Text="Ver no mapa" CommandName="ver" ButtonType="Button" />
        </Columns>
    </asp:GridView>

这是你必须做的。首先，将ButtonField更改为TemplateField：

<asp:TemplateField>
    <ItemTemplate>
        <asp:Button ID="btn" runat="server" Text="Status" CommandName="atender" OnClientClick="return confirm('Are you sure?');" />
    </ItemTemplate>
</asp:TemplateField>

在你背后的代码中，你不需要任何类型的逻辑。GridView1_RowCommand事件将在确认窗口中单击"确定"时触发。
