Javascript - Validate An Integer Range With A CustomValidator
Jan 22, 2011I'm trying to validate an integer range with a CustomValidator. The range is set dynamically, so when either the min/max values on my usercontrol change, the client validation function is updated. However, I can't get the validation function to fire. I have this code:
<asp:CustomValidator ID="vldAnswerValid" runat="server" ControlToValidate="txtAnswer" Display="Dynamic" SetFocusOnError="true" ValidationGroup="answer" OnServerValidate="vldAnswerValid_ServerValidate" Enabled='<%# !IsReadOnly %>' />
Setting the function from the codebehind with: vldAnswerValid.ClientValidationFunction = " function(oSrc, args){ alert(1); args.IsValid = false; } ";
But there's no message displayed and no alert. Am I missing something?

View 6 RepliesFileupload Within Update Panel / Can't Get The FileUpload Working Properly
Jan 15, 2010 Hopefully someone can give me some pointers to get this working properly.
I have a webpage which I would like the ability to upload files to be stored in a database. Here's the layout of the page:
[code]....
The update panel is configured as such:
ChildrenAsTriggers="True" EnableViewState="True" RenderMode="Block" UpdateMode="Always" Visible="True" Runat="Server"
The reason I have the update panel outside the Tabcontainer is so that when switching between tabs, the screen doesn't flicker with refreshes, etc. But as a result, I can't get the FileUpload working properly. The FileUpload1.Filename is blank, so it errors out.
Is there anyway to get this working properly? I've tried the latest AsyncFileupload within the control toolkit, but this caused all kinds of problems with my pages so that's out of the question. I tried an iFrame too, but this also didnt work properly.

Sep 2, 2010I have two CustomValidators, both of which function in the same way (call a query and check if a particular value is available in the DB), the only difference is the query itself.

CustomValidator On Multiple Controls?
Oct 6, 2010I am working with a page that has a series of checkboxes that at least one box must be checked.
The validator fires when I click the submit button and if no checkboxes are checked indicates the validation has failed. However If I check one of the checkboxes the validation message does not go away until I click the submit button again.
If I was using this on a control in which I had specified the ControlToValidate and I fixed the validation issue the error message goes away immediately.
However in this case I am not setting the ControlToValidate due to the neeed to validate serveral independent controls.
So my question is can I cause a re-validation of the custom validator? For instance I would like to add on each checkbox a onclick="revalidate()" that would then force the validation to happen again.
Here is some sample code that I wrote to demonstrate the scenario.
<script type="text/javascript">
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
