Error using RegisterClientScriptBlock

[Steven K]

Hello,

I am trying to create a JavaScript function and am getting the following
error: 'jsFormValidation' is not a member of 'ASP.ciJava_aspx'.

Sub Page_Load(Sender As Object, E As EventArgs)
Dim ctrlValidate As String = tbxSubmitter.ID
Dim strFormValidation As String = _
"<script language='javascript'> function jsFormValidation() {" & _
"alert('Please enter your Name in the |Name| field.');" & _
"document.getElementById('" & ctrlValidate & "').focus();}" & _
"<" & "/script>"

If(Not IsClientScriptBlockRegistered("jsFormValidation"))
RegisterClientScriptBlock("jsFormValidation", strFormValidation)
End If
End Sub


In the form:

<td width="100" align="center">
<asp:ImageButton runat="server"
ImageURL="../../images/art_dbflash_go.jpg"
ImageAlign="Middle"
AlternateText="sckeels"
OnCommand="jsFormValidation(this)"
CommandName="ASPNET"/>
</td>

You're trying to use a client-side JavaScript function to handle a
server-side event.

Hi Steven

The reason is that OnCommand is a server-side event. How can you call a client-side javascript function through server-side
Please try add this line
Imagebutton1.Attributes("onclick") = "jsFormValidation();
and remove this line
OnCommand="jsFormValidation(this)

If(Not IsClientScriptBlockRegistered("jsFormValidation")
RegisterClientScriptBlock("jsFormValidation", strFormValidation
