I have a TextBox field as shown below
<asp:TextBox id="txtIssueTo" runat="server" OnTextChanged="UserExist"
AutoPostBack="true" Text="UserName"></asp:TextBox>
The UserExist method takes the txtIssueTo value and checks if the user exist
in the database.... in the UserExist method i keep getting this error message:
Object reference not set to an instance of an object.
string strUserName = txtIssueTo.Text;

On my page, there is a textbox at the top that contains a date -- and a
fully-editable datagrid below (each row in the datagrid contains an
editable textbox, along with some other controls).

Runat="server" width="80px" CssClass="inputstyle"
onBlur='javascript:Search.submit();' OnTextChanged="Date_Changed" />

Hi.
I have created a web-based file manager. Now I'd like to watch a folder for
changes, and when a change occurs I'd like to refresh my page.
Okay. So I have created a FileSystemWatcher set on the folder I need to
watch. It works fine. The problem occurs when I need to trigger an automatic
Refresh.
So I added two handlers - OnChanged and OnRename, in the same class as my
filemanager.

I think I already know the answer to this but here goes. I've read the other
postings but no solutions for this.
If a user enters a textbox, there is no 'onenter', etc. to control firing
off a sub, etc. We have OnTextChanged. But it doesn't fire until focus is

the form, the 'Save' button gets the focus and fires event OnTextChanged but
stops...

Hi. I'm working on an intranet application that requires a user to input
information about themselves. I have a user control with a couple of
textboxes that I want the user to enter their weight into. One is for
Lbs and one is for kg and I'm using the OnTextChanged event to populate
the other control if one is filled in (converting between kg and Lbs).
It works, but when one TextBox is changed and it sets the other's value,

Hello,
I have the following textbox:
<asp:textbox id="txt_equipo" runat="server" AutoPostBack="true"
OnTextChanged="nombre_equipo" />
So when I write the code on the textbox it will automatically fill the
other fields like "name", "serial #", etc. It works, but when I use
the AutoComplete feature (when i enter a code for 2nd time) it
doesn't.

Help!
I have an ASP textbox where the OnTextChanged event is not firing. Here's the call:
<asp:TextBox ID="ApproverCopy" runat="server" CssClass="noShow" OnTextChanged="StoreNewTrainings" AutoPostBack="True"></asp:TextBox></TD>
The event fires if I enter the value manually, but not when I do it programmatically in the code behind.
Please help.

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,...
