Set focus on the field (Form validation in ASP.NET)

Hi,
I have a problem and really need your help. In my web page ASPX, I have
some text fields to accept data from users. I did form validation like this
:
<td class="dataTD" style="HEIGHT: 30px" width="100">
<asp:TextBox id="txtFUEL_ISSUED1" style="Z-INDEX: 100; POSITION: absolute"
runat="server" Width="107px" BorderColor="Transparent"
autoPostback="true"
OnTextChanged="txtFUEL_ISSUED1_TextChanged"></asp:TextBox>
</td>
<td class="dataTD" style="HEIGHT: 30px" width="100">
<asp:CompareValidator id="CompareValidator1"
runat="server" Width="90px" ControlToValidate="txtFUEL_ISSUED1"
ForeColor="LightCoral" ErrorMessage="Please enter a number!"
Operator="DataTypeCheck" Type="Double"></asp:CompareValidator>
</td>
In the txtFUEL_ISSUED1_TextChanged, I checked if data on this field is valid
or not. If it's valid then I add this value in the TOTAL field. I'd to to
set focus on the next field when this data IS VALID, OR focus on this field
when data IS NOT valid . Can you help me ? Thanks in advanceI suggest you upgrade to ASP.NET 2.0, which has new features that satisfy
all your requests.
I hope this helps,

Steve,
I have some questions:
1- There are some versions ASP.NET 2.0 from the www.asp.net web site :
a- .NET Framework 2.0 SDK x86,
b- .NET Framework Version 2.0 Redistributable Package (x86)
c- .NET Framework 2.0 SDK x64
d- .NET Framework Version 2.0 Redistributable Package x64 (64
Bit)
e- .NET Framework 2.0 SDK IA64
f- .NET Framework Version 2.0 Redistributable Package IA64
(64 Bit)
Which one do you suggest me to download ?
2- After downloading, do you think this code will work OR I should
change something ?
Sub txtFUEL_ISSUED1_TextChanged(sender As Object, e As EventArgs)
Dim strScript As String = "<script language=JavaScript>"
If IsNumeric(txtFUEL_ISSUED1.text) OR
txtFUEL_ISSUED1.text="" Then
Dim aValue as double=0.0
If IsNumeric(txtFUEL_ISSUED1.text) Then
aValue=CDBL(txtFUEL_ISSUED1.Text)
End If
' ADD the value to the TOTAL field
ViewState("FUEL_ISSUED_Total") =
ViewState("FUEL_ISSUED_Total") + aValue - ViewState("FUEL_ISSUED1")
txtFUEL_ISSUED_Total.text=FormatNumber(ViewState("FUEL_ISSUED_Total"),
2, , ,TriState.True)
ViewState("FUEL_ISSUED1") = aValue
strScript = strScript &
"document.form1.txtFUEL_ISSUED2.focus();" 'FOCUS on the next field
Else 'FOCUS on the current field
strScript = strScript &
"document.form1.txtFUEL_ISSUED1.focus();"
End If
strScript = strScript & "<" & "/script>"
If (Not Page.IsStartupScriptRegistered("clientScript")) Then
Page.RegisterStartupScript("clientScript", strScript)
End If
End Sub

If you have a 32-bit machine ( a standard Intel or AMD )...
If you want the very minimum necessary to run ASP.NET 2.0,
get .NET Framework Version 2.0 Redistributable Package (x86)
If you want the QuickStart Tutorials, extra tools *and* ASP.NET 2.0,
get .NET Framework 2.0 SDK x86
If you have a 64-bit machine, your choice may vary depending on the cpu.
The code you posted should run on any of the 5 choices.
