How can I use/reference the selected value (TextBox) from a JavaScript Function into C# Code behind?
<h1>aspx.cs:</h1>

<pre><code>&lt;script type="text/javascript"&gt;
    $(function () {
        //ALPHA
        $('#COLOR_ALPHA_TEXTBOX1').colorPicker({ pickerDefault: "E1E1E1", colors: ["E1E1E1", "33CC00", "FFF000", "CC0000", "996600", "FF9900", "303030", "0066FF", "F9A7B0", "9A0EEA"], transparency: true });
        $('#COLOR_ALPHA_TEXTBOX2').colorPicker({ pickerDefault: "E1E1E1", colors: ["E1E1E1", "33CC00", "FFF000", "CC0000", "996600", "FF9900", "303030", "0066FF", "F9A7B0", "9A0EEA"], transparency: true });
    });
&lt;/script&gt;

&lt;asp:Table ID="Table" runat="server" style="border: medium solid #000000"&gt;
&lt;asp:TableRow&gt;
    &lt;asp:TableCell ID="TC2BC" HorizontalAlign="left" VerticalAlign="top"&gt;
            &lt;asp:TextBox ID="COLOR_ALPHA_TEXTBOX1" type="text" runat="server" Visible="False"&gt;&lt;/asp:TextBox&gt;
    &lt;/asp:TableCell&gt;
&lt;/asp:TableRow&gt;
&lt;asp:TableRow&gt;
    &lt;asp:TableCell ID="TC9BC" HorizontalAlign="left" VerticalAlign="top" &gt;
    &lt;asp:TextBox ID="COLOR_ALPHA_TEXTBOX2" type="text" runat="server" Visible="False"&gt;&lt;/asp:TextBox&gt;
    &lt;/asp:TableCell&gt;
&lt;/asp:TableRow&gt;
&lt;/asp:Table&gt;
</code></pre>

<p>I tried to use on the code behind cs:</p>

<pre><code>COLOR_ALPHA_TEXTBOX1.SelectedValue 
</code></pre>

<p>But, I don't get that option in C#; What could be an alternative? Thanks so much for the help!</p>
