Add OnKeyUp to an ASP.NET TextBox

Here's a simple technique to add OnKeyUp to an ASP.NET Textbox. In the Page_Load add the following code:

C#

    protected void Page_Load(object sender, EventArgs e)

    {

        TextBox1.Attributes.Add("onKeyUp", "CallScript(this)");

    }

VB.NET

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)

        TextBox1.Attributes.Add("onKeyUp", "CallScript(this)")

    End Sub
