答

您可以将onClientClick添加到btnPayment，例如

You can add a OnClientClick to the btnPayment like

<asp:button id="btnPayment" runat="server" text="Generate Bill" commandname="cPay" commandargument="<%#((GridViewRow)Container).RowIndex%>" onclientclick="return validateControls(this);"></asp:Button>

然后验证骗局客户端上的trols如：

and then validate the controls on client side like:

function validateControls(rowObject)
{
    // validate this row controls here
    if(valid){
        return true;
    } else {
        return false;
    }
}
