Hi all!
In my app I implemented a separate worker thread that handles network
communication using Net.Sockets. It needs to make updates to a
DataTable object, which is displayed to the user by a DataGrid
control. The DataTable object is a 'public static' field instantiated
within context of the main thread.
The problem is that if I add a column to the DataTable from within the
worker thread (eg. different thread than where the DataTable...

Hi
I'm using several DataTables in my program which are updated periodically.
At the same I have those tables bound to DataGrids in my GUI. So far I've
been doing all the processing in the same program and the speed of the
processing prevented any issues when it comes to updating the GUI elements
(as DataTables are changed this triggers updates in the DataGrids), but as
soon as I add cpu time intensive processing options (i.e. receiving...

In my Win App, I have a datagrid that's bound to a dataset. When the form
loads, the datagrid fills. How can I add an empty row to the end of the
datagrid during a button click (similar to pressing Tab when mouse pointer
is on last field of last record of datagrid)? The datagrid's read-only so
the user won't be able to modify it unless he wants to add a new record via
the datagrid (by adding the empty row).
Also, if I modify the...

How can I update the datatable with the datagrid values after the datagrid
itself has been modified.? I assume it's not automatically done.
Thanks.

Does anybody know how to write the following code?
I have a database table with a few columns including: ID , "Task"

these selected fields and allow user to click one or more CheckBox controls
to activate this bit on the database table for a required ID.

I have a DataGrid web control which I've dynamically populated with
template columns to be used for bulk-editting. Generally, all of the
columns are textbox and/or dropdownlist child controls.
Currently everything is working. I can find the updated rows/columns
by parsing the posted data collection against the DataGrid DataSource.
However, when there is a large amount of DataGridItems (rows) the
update processing can take a while.

Hi, I am trying to use a data grid in a web application in which I have
three tiers. The DataGrid is not set up to a data source, or a data adapter,
so everytime I make a change I send the cell information to another object
which forms an SQL query and makes the query to the DB (actually to a
DBFacade object). In any case, please see the code I have listed below for
my update DataGrid event. With this code, the DB is updated using the old...

I bound a DataGrid to a table (I tried with a DataView too).
I removed the row from the table, and then inserted a new
row at the same row index. the table gets the row to the
right position, but the bound DataGrid does not pick up
and appends the inserted row at the bottom of the grid,
not the right position?!?
Any ideas how to make the DataGrid pick up the changes
done in the table - to show the inserted row at the right
position?

Hi,
I am writing a windows app in .net 2003. I have a datagrid which gets
data from a storedprocedure. My question is how can I update the data
in the datagrid? I want to call another storedprocedure to update the
data in the datagrid.
Thanks in advance.

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,...
