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?

Apr 6, 2010Can any one let me know "How to validate the length of the text present in the textboxes of a Gridview using javascript".
For Example: In a page I am displaying a Gridview with textboxes inside it and a button on the page. The user need to input some text in the textboxes of the gridview and click on "Submit" button. When the user clicks on Submit Button, we need to validate the length of the text present in the textboxes of the gridview. If the length of the text inside the textbox of the gridview is less than 10 , we need to throw an error message. In the same way we need to do validation for each and every textbox inside the gridview.
