Dynamically added event selectedindexchanged to radiobuttonlist(dynamically generated) may not execute all the time when navigating between the radio button. It will execute once if the radio button is not clicked before.
Please advise.

It's impossible to provide an accurate answer without the code that causes this situation. We can only guess how the code works.

Dynamically generated events (and controls) must be re-created on every post back, usually the Page_Load event. This is a very common design mistake in ASP.NET Forms.

There will be a case that the Page.Load event is too late. I suggest the Page.Init event.

Thanks. I will try to place the code in the page init event instead of page load event.

Hi everyone,
I found a workaround.
I will retrieve the datatable and assign to the radiobuttonlist web control but not dynamically create the webcontrol on the page load function. Tested and working fine now.
Thank you.
