Problem with ASP.Net control or JavaScript ???

Nov 15th, 2007

Dear all,
I get problem with this ASP.Net form.
As you can see in the sources, I have Check Box (ChkAllCustomer), Combo Box (CmbDept) and Command Button (CmdLocateCustomer).
And to avoid postback I use JavaScript event instead of Anthem.Net.

Everytime user clicks ChkAllCustomer.Checked = true, CmdLocateCustomer enable property is set to false and CmbDept enable property is set to true.
In the other way, if ChkAllCustomer.Checked = false, CmdLocateCustomer enable property is set to true and CmbDept enable property is set to false.

Problem occurs when user clicks CmdLocateCustomer, but somehow CmdDept enable property is set to true manually where as there is not code in CmdLocateCustomer click event.

Please help me.

Thanks and regards,

Kusno.

try to explain a litter further on what needs to be done. It was a bit confusing.. or if you could provide a link?

Also, in your javascript, you're not declaring where the form sits. Set a var = document.forms.form1 and then call it everytime you need it. So this means change your javascript code to:

 Help with Code Tags 
 ASP.NET Syntax (Toggle Plain Text) 
<script language="Javascript" type="text/javascript">
function ChkAllCustomerClick()
{ 
var identity = document.forms.form1;
if(identity.ChkAllCustomer.checked == true)
{
identity.TxtCustomerId.value = "";
identity.TxtCustomerName.value = "";
identity.CmdLocateCustomer.disabled = true;
identity.CmbDept.disabled = false;
}
else
{ 
identity.CmdLocateCustomer.disabled = false;
identity.CmbDept.disabled = true;
}
}
</script>
<script language="Javascript" type="text/javascript">
function ChkAllCustomerClick()
{ 
var identity = document.forms.form1;
if(identity.ChkAllCustomer.checked == true)
{
identity.TxtCustomerId.value = "";
identity.TxtCustomerName.value = "";
identity.CmdLocateCustomer.disabled = true;
identity.CmbDept.disabled = false;
}
else
{ 
identity.CmdLocateCustomer.disabled = false;
identity.CmbDept.disabled = true;
}
}
</script>

As for the rest of your code, keep in mind that when it is rendered on page, the ID for that code is different then you chose for it to runat server. View Source on your browser after running the code. Try not to use runat server controls if you don't have to. HTML controls are faster and obviously don't use server resources. So for your cmdLocate button or whatever, make that an HTML button and disabled="disabled" value. This should solve your problem.

CmdLocateCustomer is used to open popup window and send value to it parent page.

In ASP.Net :
Protected Sub CmdLocateCustomer_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles CmdLocateCustomer.Click
Dim S As String = PopUpWindow("w_customer", "../../Browse/LocateCustomerMaster.aspx?CustomerId=form1.TxtCustomerId&CustomerName=form1.TxtCustomerName", 880, 550)
If ClientScript.IsClientScriptBlockRegistered("w") = False Then
ClientScript.RegisterClientScriptBlock(Me.GetType(), "w", S)
End If
End Sub

In Javascript :
function CmdLocateCustomer_onclick() {
var w = window.open('"../../Browse/LocateCustomerMaster.aspx?CustomerId=form1.TxtCustomerId&CustomerName=form1.TxtCustomerName','window');
w.focus();
}

I can use one of both scripts. But at least, I want to know why that problem occours when I use ASP.Net control
