Web Forms send text from textbox to method onChange event

I'm new in web forms. I need to send text from aspx page to server method using onChange in this textbox:

Email: <asp:TextBox ID="FilterAccountsTextBox" runat="server"/>

May anyone help me?

-------------Problems Reply------------

Here you are. After you type on TextBox2 and leave it. The TextBox2.Text is post to Server (based on AutoPostBack attribute) to update Label1.

ASPX:

<asp:TextBox ID="TextBox2" runat="server"
AutoPostBack="True" OnTextChanged="TextBox2_TextChanged"></asp:TextBox>
<asp:Label ID="Label1" runat="server" Text="You type: "></asp:Label>

CS:

protected void TextBox2_TextChanged(object sender, EventArgs e)
{
Label1.Text = "You type:" + TextBox2.Text;
}

Hope this help.
