Call Server Side function with Keyup Event in Asp.Net
<p>I have a TextBox and I want to capture the <code>Keyup</code> in the Textbox and get the TextBox value at the Code Behind File and Bind The GridView with the Input Received from the TextBox.</p>

<p>I don't want to use <code>Text_Change</code> Event of Asp.net. i want that when ever user enter anything in the TextBox, that value should go to code behind and bind the grid by calling <code>BindGrid</code> Function</p>

<pre><code>&lt;asp:TextBox ID="txtSearch" runat="server"&gt;&lt;/asp:TextBox&gt;

protected void BindGrid(string searchvalue)
{    
    //  i want the txtSearch value over here.    
}
</code></pre>
