Hi,
I am facing certain issues with ASP.NET validator control (to be specific RangeFieldValidator - RFV & CustomFieldValidator CFV)
I have implemented RFV on a text box which checks that the value entered in the text box should not be less that 0 & the CFV check if the selected value on a particular drop down (ddlChannel) is either "A" OR "B" the value must be selected in another drop down (ddlLocation) related to that drop
But when my page gets loaded for the first time & I click the "Save" button, these validators dont get triggered & then if there is any post pack on that page the validators start working as expected.
Below is my RFV & CFV logic:
RFV Logic
========
<asp:RangeValidator ID="vldMarginRange" ControlToValidate="txtMargin"
Type="Integer" MinimumValue="1" MaximumValue="99" Enabled="True" runat="server">* You must enter a whole number between 1 and 99</asp:RangeValidator>
CFV Logic
========
<asp:CustomValidator id="CustomValidator1" runat="server" ControlToValidate="ddlWBSLocation"
CssClass="ms-descriptiontext" ClientValidationFunction="CheckWBSLocation"
Display="Dynamic">
* You must select a Location for the Contract Template "A" or "B"
</asp:CustomValidator>
function CheckWBSLocation(source, arguments)
{
var channel = document.forms[0].elements.<%= ddlChannel.ClientID %>;
var WBSLocation = document.forms[0].elements.<%= ddlWBSLocation.ClientID %>;
if(channel.value == 'A' || channel.value == 'B')
{
if (WBSLocation.selectedIndex == 0)
{
arguments.IsValid = false;
return;
}
}
arguments.IsValid = true;
}
Is there setting that I might be missing?

What save button ? Validators work on attempted postback, is your save button using AJAX or something ?
You can look at hte script generated for validators and write your own code to call them, that's how I did it when I wrote pages using validators and posting data with AJAX

No my Save button is not using any AJAX logic. Whats "hte script" u are talking about?
I even tried using ValidationGroup on all validators but that too didnt worked out as expected.
Is there any page level setting that needs to be done?

You said that when you postback it validates. Do you mean it posts back and validates on the server side only ? I am trying to work out your situation from what you said. Does your button do a postback and the validators don't work ?

Yes absolutely correct. On click of "Save" button the server side logic saves the data in to database. But before that if the data input is wrong than it should validate the controls first.
Am I correct?

Yes. Not sure why that would not be the case. You can add a custom validator and use firebug/firefox to confirm they are firing.

Yes the validators should run before any data is sent to the server, im pretty sure on this, is it possible to post all your code, or is it too much
cheers

Then its a weird behavior....
I guess I need to dig dip in to it
Is there any page level settings for validators?

Have you chekced that none of your controls have causevalidation = false
This would be that it would by pass the validation
|
|
|
|
|
Infact what happens is when I try to save my page with invalid data, the page doent gets posk back but also it does not show up the validation message.
This is the issue with it.

Hello Friends!
I've faced a probelm. pls help me.
I am trying to verify whether the path to the webservice hosted in iis is valid by the following code.
HostingEnvironment.VirtualPathProvider.FileExists("http://localhost/WSClientProxy/teste.asmx");
But every time it displays "'http://localhost/WSClientProxy/teste.asmx' is not a valid virtual path."
How can I get the virtual path?
Thanks!

Hi, Samrat.
The problem is that you're trying to use a file system routine (FileExists) with the virtual web url path that the browser uses. As you might suspect, these are completely different things.
MapPath() (I think it's in the Server namespace) will take a virtual path like "~/WSClientProxy/teste.asmx" and give you back a physical path to the filesystem. For example, MapPath("~/WSClientProxy") will give you the physical directory pointed to by this virtual path. You can then use that directory to create files, etc. and of course you can use MapPath("~/WSClientProxy/teste.asmx") as the parameter to FileExists(). If you play around with it and do some tests with creating, renaming (MoveTo()) deleting files, etc., I think you'll get the hang of it.
Hope this helps!

Looks like SMTP server is not installed on your machine. Check that in the IIS settings.

I've been working with ASP .NET and data for a couple months now. I'm creating a web app that is more or less a "virtual worksheet" with multiple choice questions. I get the question text and four answers from an Access database. Using data from an invisible GridView, I create Labels and RadioButtonLists at runtime and add them inside a View in my MultiView.
For I As Integer = 0 To Me.gvQMultipleChoice.Rows.Count - 1<br />
Dim lbl As New Label<br />
lbl.ID = "lblQ" & I<br />
lbl.Text = I + 1 & ". " & Me.gvQMultipleChoice.Rows(I).Cells(0).Text<br />
Me.vw1.Controls.AddAt(Me.vw1.Controls.Count - 5, lbl)<br />
Dim rad As New RadioButtonList<br />
rad.ID = "rad" & I<br />
For I2 As Integer = 0 To 3<br />
rad.Items.Add(SwitchChar(I2) & ". " & Me.gvQMultipleChoice.Rows(I).Cells(I2 + 1).Text)<br />
Next<br />
rad.RepeatDirection = RepeatDirection.Horizontal<br />
Me.vw1.Controls.AddAt(Me.vw1.Controls.Count - 5, rad)<br />
Next
Basically, make a Label, get its question text, add it to the View. Same with the RadioButtonList. This works fine. My problem is later, when I am trying to find out which RadioButton is selected. Me.vw1.Controls doesn't contain any of these Labels or RadioButtonLists.
<br />
Dim myControls As ControlCollection = Me.vw1.Controls<br />
For I As Integer = 0 To myControls.Count - 1<br />
If myControls(I).ID <> Nothing Then<br />
If myControls(I).ID.StartsWith("rad") Then<br />
Dim rad As RadioButtonList = Me.vw1.Controls(I)<br />
ans &= rad.SelectedIndex<br />
Else<br />
'ignore<br />
End If<br />
End If<br />
Next
This should work fine, I'm confident it would. But again, the problem is that the dynamically created controls aren't in the list. Does anyone know why it would be like this.
By the way, the Labels and RadioButtonLists show up, and I can select a RadioButton. The second bit of code is executed on a Button.Click event.
Thanks!
(Yes, this also in the Web Dev section. Sorry I posted there first.)

When do you add the controls ? If you add them in the prerender event, then the issue is that the click event fires first.

The controls are added in the View.Activate event. Yes, the same view that contains the dynamically-added controls and the Button that is clicked.

OK, I'm not familiar with that event, I'd set breakpoints to see if it's called after you search for the controls or not.

It's just the event that fires when the MultiView's ActiveViewIndex property is changed and the View begins to load.

Hi
<asp:Menu ID="Menu1" runat="server" OnMenuItemClick="Menu1_MenuItemClick" Orientation="Horizontal"><br />
<Items><br />
<asp:MenuItem Text="Main Menu" Value="Test"><br />
<asp:MenuItem Text="Second" Value="secondform.aspx"></asp:MenuItem><br />
<asp:MenuItem Text="Third" Value="thirdform.aspx"></asp:MenuItem><br />
</asp:MenuItem><br />
</Items><br />
</asp:Menu><br />
<asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server"><br />
</asp:ContentPlaceHolder>
and my Menu1_MenuItemClick event is:
protected void Menu1_MenuItemClick(object sender, MenuEventArgs e)<br />
{<br />
Server.Transfer(((System.Web.UI.WebControls.Menu)(sender)).SelectedValue); <br />
}
When I click the menu item, URL show the previous SelectedValue. Not the page is currently shown.
Any help would be appreciated.
Thanks
Muthu

Hi kmuthuk,
