在用户控件中查找控件 [英] Find control inside usercontrol

问题描述

我里面有一个用户控件和Gridview. Gridview有两列，一列是文件上传器，第二列是文本框.

我正在使用javascript将新行添加到gridview，以便在每一行上重复我的上传器和文本框.

我将此用户控件放在其他aspx页面中.

从后面的代码中，我想访问所有文件上传器和文本框，但无法找到它们.

我正在给我我的Usercontrol标记.
请给我一些破解的逻辑.
----------标记-----------

Hi,

I have a usercontrol and Gridview inside it. Gridview has two columns one has file uploader and second has textbox.

Using javascript I am adding new row to gridview, so that my uploader and textbox get repeated on every row.

I put this user control in other aspx page.

From the code behind i want to access all file uploaders and textboxes, but not able to find them.

I am giving you my Usercontrol markup.
Pls get me some logic to crack this.
---------- markup -----------

<%@ Control Language="C#" AutoEventWireup="true" ClientIDMode="Static" Inherits="User_Controls_uclDynamicUploader"

    CodeBehind="uclDynamicUploader.ascx.cs" %>
<script language="javascript" type="text/javascript">

    // function will add new row to grid if user clicks "+" image.
    function AddRow() {

        var hdnMaxGrid = document.getElementById('hdn001UctlMaxGrid').value // gets hidden variable value.
        var grd = this.document.getElementById('grd');
        if (grd.rows.length == Number(hdnMaxGrid) && Number(hdnMaxGrid) != 0) {
            alert("Can't add more");
            return false;
        }
        var tbod = grd.rows[0].parentNode;
        var newRow = grd.rows[grd.rows.length - 1].cloneNode(true);
        tbod.appendChild(newRow);
        var rowIdx = 1;
        for (rowIdx; rowIdx < grd.rows.length; rowIdx++) {
            var txtbox = grd.rows[rowIdx].cells[2].firstChild;
            var pp = txtbox.value;
            document.getElementById('hdnpp').value = pp;
        }

        return false;
    }
    // function will delete row from grid if user clicks "-" image on that row.
    function RemoveRow(ctrl) {
        var grd = document.getElementById('grd');
        var row = ctrl.parentNode.parentNode; //to get row containing image
        var rowIndex = row.rowIndex; //row index of that row.
        if (grd.rows.length < 2) {
            alert("Can not delete");
        }
        else {
            grd.deleteRow(rowIndex);
        }
        return false;
    }
