by: JT | last post by:

This seems like it could be an asp.net bug. I am getting the following exception when I add OnSortCommand attribute to a datagrid. I have deleted the temp directories, rebooted etc and I have isolated it to the OnSortCommands presence. When I use a code behind it doesn't fire any events on the back end and the global error handler grabs it. I put together a very simple example to illustrate the problem below.

GridView Blank with AllowPaging="True"

by: Jonathan Wood | last post by:

Okay, I spent about 3 hours getting the GridView control to do what I needed. Basically, I set the control's AutoGenerateColumns to False and then defined a single template column (which I will customize with my own content). This looks something like this: <asp:GridView ID="GridView1" runat="server" CellPadding="4" ForeColor="#333333" GridLines="None" AutoGenerateColumns="False" Width="100%" AllowPaging="False"

The problem is that every works really fine with this code when customers order approximatelly a maximum of 35 products.

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.
