Is it possible to dynamically assign a CommandArgument to an asp.net button using JavaScript?

My GridView has a list of items where one of the columns contains a link that triggers a modal display using AjaxToolkit ModalPopupExtender. This link is labeled as "Show". Inside the modal, there is an asp:button for saving the data entered, which is labeled as "Save".

When a user clicks on the "Show" link in a specific row, I want to implement JavaScript that modifies something in the "Save" button. This will allow me to handle the "Save".Command in my code-behind and utilize the CommandEventArgs parameter to access the value.

Is it possible to achieve this through JavaScript manipulation or do I need to resort to using a hidden input tag and setting its value instead?

Answer №1

While this may not directly address your specific question, there is an alternative solution that could potentially resolve the issue at hand:

Consider implementing a HiddenField element within your webpage. Within the backend code, assign the ID of the selected row (or any other identifying value) to this hidden field before triggering the modal popup. Subsequently, when handling the Save button functionality in your backend logic, you can easily retrieve the stored value from the HiddenField.

Answer №2

Upon further investigation, it appears that the task is unachievable. The CommandArgument attribute seems to be stored in the ViewState and cannot be manipulated with javascript as it is strictly server side.

Answer №3

To effectively utilize the UpdatePanel, ensure that the HiddenField is placed within. Failing to do so may result in the inability to access or modify the hidden field value.
