Entering string into textbox.value (JavaScript) via button (asp.net)

Question

I am using Microsoft Visual Web developer 2010. I have a textbox (txtBoxInput) using the code: <input type="text" id="txtBoxInput"/>

I also have an aspn.net button (btnTest) using the code:

<asp:Button ID="btnTest" runat="server" onclick="Button1_Click" Text="Button"/>

And the code in btnTest's event:

protected void Button1_Click(object sender, EventArgs e)
{
    string test = txtBoxInput.Value = "test123";
}

However txtBoxInput control is not detected. Is there a way where writing this C#/aspn.net code can put this string (test) into txtBox.Value. Thanks

You need to add runat="server". Otherwise input won't be visible on server side and you'll need to access posted value trough Request.Form collection.

<input runat="server" type="text" id="txtBoxInput"/>
