        rows = document.getElementById("<%= GV1.ClientID %>").rows;
        for (i = 0; i < rows.length; i++) {
            rows[i].cells[8].style.display = "none";
        }
        for (j = 0; j < rows.length; j++) {
            rows[j].cells[9].style.display = "none";
        }
    }
    // change logic to suit taste
    function clicked() {
        var b = HidColumn();

  <asp:ImageButton ID="ImageButton2" runat="server" ImageAlign="Right" ImageUrl="images/printer.jpg"
                    Style="margin-left: 5px; margin-right: 15px" OnClick="ImageButton2_Click" Width="36px"
                    OnClientClick="return clicked()" Visible="false" />

但是,当我单击ImageButton时,没有发生任何事情

打印GridView时隐藏它的两列Asp.net

这一行没有意义:var b = HidColumn();

函数HidColumn不返回任何内容。

AS我说过我同意steve的答案,您应该修改函数HidColumn以返回true或false。还有一点我想提一下,如果您从clicked((返回false,那么postback将不会发生,否则它将调用服务器上的ImageButton2_Click事件。

function HidColumn() {
        // col_num = document.getElementById("Button").value;
        rows = document.getElementById("<%= GV1.ClientID %>").rows;
        for (i = 0; i < rows.length; i++) {
            rows[i].cells[8].style.display = "none";
        }
        for (j = 0; j < rows.length; j++) {
            rows[j].cells[9].style.display = "none";
        }
        if(someCondition)return true;
         else return false;
    }

更新:-您已将控件可见性设置为False,因此不会渲染控件。因此,您无法在javascript中获取Element,因为该控件将没有HTML。如果你想隐藏控件,只需使用Javascript:-

<asp:somecontrol id="ctrl" style="display:none" />

只需将隐藏列代码放入打印函数中,如下所示:

function PrintPage() {
        rows = document.getElementById("<%= Gv1.ClientID %>").rows;
        for (i = 0; i < rows.length; i++) {
            rows[i].cells[8].style.display = "none";
            rows[i].cells[9].style.display = "none";
        }
        var printContent = document.getElementById('<%= pnlDtls.ClientID %>');
        var printWindow = window.open("All Records", "Print Panel", 'left=50000,top=50000,width=0,height=0');
        printWindow.document.write(printContent.innerHTML);
        printWindow.document.close();
        printWindow.focus();
        printWindow.print();
    }
