        Dim sb As New System.Text.StringBuilder()

        sb.Append("if (typeof(Page_ClientValidate) == 'function') { ")

        sb.Append("if (Page_ClientValidate() == false) { return false; }} ")

        sb.Append("this.value = 'Please Wait...';")

        sb.Append("this.disabled = true;")

        sb.Append(Me.Page.GetPostBackEventReference(Me.btnSubmit))

        sb.Append(";")

        btnSubmit.Attributes.Add("onclick", sb.ToString())

Setting focus to a field in asp.net

mwgriffith (Michael Griffith) — Thu, 05 Jun 2008 15:29:49 GMT

This code does a simple field focus in asp.net.



    Protected Sub setFieldFocus(ByVal ctrl As System.Web.UI.Control)

        Dim s As String = ""

        ClientScript.RegisterStartupScript(Me.GetType, "focus", s)

    End Sub



     Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

        If Not Page.IsPostBack Then

            BindData()

        End If

        setFieldFocus(txtSpecies)

    End Sub

The basic idea here is to pull the id's from asp.net so that it can be used in a javascript environment.
