Hi,

If I got you right you want to play with div visibility on parent page
after called (dialog) window return values back to the calling page. if
this the case its better to achieve it using client side script and
DHTML. Round trips to server are useless here.

if you want server side event on calling page to be happened when dialog
window return value you can use client side script by submitting form or
calling __DoPostBack with right parameters and cause post back.

I have sub-classed the TextBox. In its OnKeyDown event I can intercept key strokes, examine them, etc. When I get a certain keycode (e.g., 'A') I want to change it to another unicode key from a different code page (e.g., "\u2801"). But the KeyCode, KeyData, and KeyValue properties of KeyEventArgs are all only getters. They are read only and thus do not permit changing the assigned KeyCode. My question is this: How do I change the KeyCode...

I'd like to know if it's possible to change the contents of a div tag based on something the user is doing. For example. If there is a text box on a page and the user types his or her name can I update an existing div tag to show what they've typed in? Thanks.

Hi ! I have a Wep App in C#. Page_Unload fires after Page_Load, and it seems totally unreasonable when you want to use this event when you _leave_ the page.

I have a form with some controls on it, one of them has an auto postback onchange. So the postback occurs but before the event fires, all the controls are recreated. so my question is, if the event requires you to replace a control with another type, e.g. replace a textbox with a date control, how do I get it to redo the form with the new control, force another postback ? if so , how ? Thanks Adrian Parker

I have an ASP.NET page where controls are created dynamically, and I have an issue where one event handler creates another set of controls, and then adds event handlers to those controls. The problem comes in where I need to raise the event in the second control - the event does not fire. I have distilled the example below down to it simplest: on Page_Load one button is created, and a Click event hander is added to the button. When...

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
