The more I use ASP.NET, the more if (!IsPostBack) {} seems pointless... First example: For example, I just Googled an issue, they said use this as part of the solution: if (!Page.IsPostBack) { Page.LoadComplete += new EventHandler(Page_LoadComplete); } Which does exactly as coded, LoadComplete will only fire on the first load. A...

The problem is that when I select a date from the Calendar and post it to the form, the TextBox that is being extended IS being updated, but the ...

Hi everyone, I have an ASP.Net page with two ListBox components, rendered in the browser as <select> lists. I'm using jQuery to move elements from one list to another by manipulating the DOM.

I am programatically adding a control to an aspx page and binding a server side event to an index changed event inside the control. (It's a RadListBox from Telerik's ASP.NET controls) The problem is that on the postback triggered from the control, the event doesn't hit its eventhandler because on the postback the control isn't defined. ...

I have enabled the AutoPostBack property of one of my form's textboxes, which according to w3 schools should only trigger a postback when I press enter or tab. I am also calling a __doPostBack() on pageLoad, given a user's answer to a javascript prompt. When I do that, the Request.Form['__EventTarget'] is not what I set it to be in the...
