Unsuccessful using .FindControl() on a div
<p>I have a html div element containing multiple divs with values that I want to put in an array server side!</p>

<p>my html divs look something like:</p>

<pre><code>&lt;div id="clientGrid" runat="server"&gt;
    &lt;div id="cell_0_0" runat="server" class="box" onclick="clicked(this)"&gt;2&lt;/div&gt;
    &lt;div id="cell_0_1" runat="server" class="box" onclick="clicked(this)"&gt;1&lt;/div&gt;
    &lt;div id="cell_0_2" runat="server" class="box" onclick="clicked(this)"&gt;3&lt;/div&gt;
    &lt;div id="cell_0_3" runat="server" class="box" onclick="clicked(this)"&gt;4&lt;/div&gt;

    &lt;div id="cell_1_0" runat="server" class="box" onclick="clicked(this)"&gt;3&lt;/div&gt;
    &lt;div id="cell_1_1" runat="server" class="box" onclick="clicked(this)"&gt;2&lt;/div&gt;
    &lt;div id="cell_1_2" runat="server" class="box" onclick="clicked(this)"&gt;4&lt;/div&gt;
    &lt;div id="cell_1_3" runat="server" class="box" onclick="clicked(this)"&gt;1&lt;/div&gt;

    &lt;div id="cell_2_0" runat="server" class="box" onclick="clicked(this)"&gt;4&lt;/div&gt;
    &lt;div id="cell_2_1" runat="server" class="box" onclick="clicked(this)"&gt;3&lt;/div&gt;
    &lt;div id="cell_2_2" runat="server" class="box" onclick="clicked(this)"&gt;2&lt;/div&gt;
    &lt;div id="cell_2_3" runat="server" class="box" onclick="clicked(this)"&gt;1&lt;/div&gt;
&lt;/div&gt;
</code></pre>

<p>i want the values of these divs to go into an array server side. My current code looks like this:</p>

<pre><code>for (int i = 0; i &lt; _grid.getGridSize(); i++)
{
    for (int j = 0; j &lt; _grid.getGridSize(); j++)
    {
        string divId = string.Format("cell_{0}_{1}", i.ToString(), j.ToString());
        Control div = clientGrid.findControl(divId);
        //more code underneath
    }
}
</code></pre>

<p>so the div id's are generated by the string format, no problem...</p>

<p>but the <code>clientGrid.findControl always = null</code>! even if i put the sting directly into the constructor like <code>clientGrid.findControl("cell_0_0");</code> it still returns NULL! How is this possible?</p>

<p>It is my understanding the the <code>findControl</code> method finds server control elements with the string id?</p>

<p>I can't access the child divs directly like <code>cell_0_0.clientID</code> because the child divs are generated by the server at runtime.</p>

<p>on page load, this function is run...</p>

<pre><code>    for (int i = 0; i &lt; _grid.getGridSize(); i++)
    {
        for (int j = 0; j &lt; _grid.getGridSize(); j++)
        {
            returnElement += " &lt;div ";
            returnElement += "id=\"cell_" + i + "_" + j + "\" ";
            returnElement += "runat=\"server\" ";
            returnElement += "tabindex=\"-1\" ";
            returnElement += "class=\"box\" ";
            returnElement += "onclick=\"clicked(this);\" ";
            returnElement += "onkeypress=\"changeValue(event, this);\" ";
            returnElement += "style=\"top:" + top + "%; left:" + left + "%;\"&gt;";

            returnElement += test[i, j];

            returnElement += "&lt;/div&gt;\n ";

            left = left + 20;
        }
        left = 0;
        top = top + 20;
    }
    return returnElement;
</code></pre>

<p>test[,] is a 2d array containing integer values. these divs are then put into clientGrid by clientGrid.innerHtml = allMyDivs</p>

<p>The users then edits the values of these divs to whatever they want, and then when the user clicks a button, the values of these divs need to somehow end up back in the serverside code so i can process them.</p>

<p>The clientGrid.control.count = 0 ... ??? so obviously... to the asp, these div elements do not exist... to asp.net... there is NOTHING inside the clientGrid div... but... the inspect element on my chrome browser says othervise! Whats Going On??</p>
