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

bienwell

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_ISS UED1" style="Z-INDEX: 100; POSITION: absolute"
runat="server" Width="107px" BorderColor="Tr ansparent"
autoPostback="t rue"
OnTextChanged=" txtFUEL_ISSUED1 _TextChanged"></asp:TextBox>
</td>

<td class="dataTD" style="HEIGHT: 30px" width="100">
<asp:CompareVal idator id="CompareVali dator1"
runat="server" Width="90px" ControlToValida te="txtFUEL_ISS UED1"
ForeColor="Ligh tCoral" ErrorMessage="P lease enter a number!"
Operator="DataT ypeCheck" Type="Double"></asp:CompareVali dator>
</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 advance

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(se nder As Object, e As EventArgs)
Dim strScript As String = "<script language=JavaSc ript>"

If IsNumeric(txtFU EL_ISSUED1.text ) OR
txtFUEL_ISSUED1 .text="" Then
Dim aValue as double=0.0
If IsNumeric(txtFU EL_ISSUED1.text ) Then
aValue=CDBL(txt FUEL_ISSUED1.Te xt)
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=Form atNumber(ViewSt ate("FUEL_ISSUE D_Total"),
2, , ,TriState.True)
ViewState("FUEL _ISSUED1") = aValue

strScript = strScript &
"document.form1 .txtFUEL_ISSUED 2.focus();" 'FOCUS on the next field

Else 'FOCUS on the current field
strScript = strScript &
"document.form1 .txtFUEL_ISSUED 1.focus();"
End If

strScript = strScript & "<" & "/script>"
If (Not Page.IsStartupS criptRegistered ("clientScript" )) Then
Page.RegisterSt artupScript("cl ientScript", 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.
