comma is appearing in textbox on postback?

Hello Karthik.K,

It seems like you are encountering an issue where a comma is automatically appearing in the Textbox on postback within the update panel and even in a Popup window. This could be due to various reasons, such as JavaScript or server-side code manipulating the Textbox value.

To address this issue, you can try the following approaches:

1. JavaScript Solution:

You can use JavaScript to remove any unwanted characters like commas from the Textbox value during the postback. Here's a basic example using jQuery:

   $(document).ready(function() {
       $('#yourTextBoxId').change(function() {
           var textValue = $(this).val();
           textValue = textValue.replace(/,/g, ''); // Replace commas with an empty string
           $(this).val(textValue);
       });
   });

2. Server-Side Solution:

In your server-side code (C#, VB.NET, etc.), you can strip out the commas from the Textbox value before processing it further. This way, you ensure that no extra commas are added or retained during postback.

3. UpdatePanel Considerations:

If you are using an UpdatePanel, ensure that the Textbox is properly updated within the update panel's partial postback cycle. Sometimes, improper handling of controls within UpdatePanel can lead to unexpected behavior like the addition of commas.

4. Debugging Popup Window:

When dealing with the Textbox in a Popup window, make sure that the scripts or events handling the Textbox values are functioning correctly. Inspecting the elements using browser developer tools can help identify any scripts causing the automatic addition of commas.

By implementing these suggestions and investigating the JavaScript, server-side code, and update panel interactions, you should be able to prevent the unwanted commas from appearing in the Textbox on postback.

I hope this guidance helps you resolve the issue you are facing. If you need further assistance or more specific insights, feel free to provide additional details. Good luck with solving the comma issue in your Textbox!
