It seems that you're experiencing difficulties with a link button inside an update panel and required field validation. Without seeing your specific code, it's challenging to provide an exact solution. However, I can offer some general guidance to help you troubleshoot the issue. Ensure the UpdatePanel triggers the necessary events: Check that the required events trigger the UpdatePanel's update. For example, if you have a validation control inside the UpdatePanel, make sure its associated event triggers the update. Use the PostBackTrigger for the link button: If the link button doesn't trigger an update inside the UpdatePanel, you can specify it as a PostBackTrigger explicitly. Add the following code within your UpdatePanel: Replace YourLinkButtonID with the actual ID of your link button. Check for any JavaScript conflicts: If you have any JavaScript code that might interfere with the link button's behavior, make sure it's not causing any conflicts. JavaScript errors or conflicts can prevent the button from working correctly. Verify the required field validation settings: Double-check your required field validation settings to ensure they are correctly configured. Make sure the validation control is associated with the appropriate input control and has the necessary error message. Test without the required field validation: Temporarily remove the required field validation to determine if it's causing the issue. If the link button works without the validation, then the problem likely lies within the validation settings. Debug and inspect the generated HTML: Inspect the generated HTML using browser developer tools and check if the link button's attributes, such as disabled , are being set correctly. This can help identify if there are any conflicts or issues with the generated markup. Thanks

To prevent multiple click events on a LinkButton inside an UpdatePanel, you can utilize JavaScript/jQuery to disable the LinkButton after the first click. Here's an example approach you can try: 1. Add the following code inside the ` ` tag of your ASP.NET page to include jQuery: 2. Add the following JavaScript/jQuery code: $(document).ready(function() { // Get the LinkButton element by its ID var linkButton = $("# "); // Attach a click event handler to the LinkButton linkButton.on("click", function() { // Disable the LinkButton to prevent multiple clicks linkButton.attr("disabled", "disabled"); }); }); Make sure to replace `YourLinkButton` with the ID of your actual LinkButton control. This code will disable the LinkButton when it is clicked for the first time, preventing subsequent clicks until the page is refreshed or updated. Note: The `ClientID` property is used to ensure the correct ID of the LinkButton is rendered on the client-side, especially when the LinkButton is inside an UpdatePanel or NamingContainer. Remember to test the behavior thoroughly to ensure it meets your requirements and doesn't interfere with any other functionality on your page.
