Problem with data grid - Visual Basic .NET

ashwin

I have a Data Grid to display employee names and codes. On clicking a
button (outside the datagrid) I perform some calculations which sets
the fields of other columns in the datagrid.
The problem I am facing is that not all columns are filled with values
resulting from the calculations. Only the first few rows are being
filled with results.

---------------------------------------------------------------------------------------------------------------------------------------------
The datagrid code follows :

<asp:datagrid id="dg1" runat="server" Width="920px" Height="145px"
PageSize="5" AutoGenerateCol umns="False"
BorderStyle="Gr oove">

Backtracking Recursion Problem

Hi everyone! I am trying to write a program that will search a 12x12 for a thing called a "blob". A blob in the grid is made up of asterisks. A blob contains at least one asterisk. If an asterisk is in a blob, an asterisk that is contiguous to it is in the same blob. If a blob has more than two asterisks, then each asterisk in the blob is contiguous to at least one other asterisk in the blob. For example this 12x12 grid has 6 blobs. ...

The easy way to turn off automatic updates for Windows 10/11

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,...
