The following assumes a System.Windows.Forms.DataGrid with a System.Data.DataTable set as the DataSource. I'm programming in C#
Here's my scenario
I click in a cell on a DataGrid. I enter some text. Before changing to another cell in the DataGrid, I move my mouse pointer off the DataGrid and change the selected item in a ListBox or TreeView.
Here's my question
Which should fire first, the DataTable's RowChanged/CellChanged event or...

Hello,
I have got a DataGrid and a DataTable, which is its DataSource.
I can use DataTable.Rows.Find(key_value) method to locate any row
in the DataTable, using values of key column. The result is a DataRow
object.
How to find and select the current position of this DataRow in
the DataGrid control?

I've been bothered for some time about my DataGrid not populating my rows
very quickly. I have about 10K rows loading into the grid.
I create a datatable dt with 2 columns, an ID and a display. The ID is a
member of the keys array.
I then create a DataView dv over the table, and sort it by Display and ID
column (in case of duplicate Display).
I then set my DataGrid.DataSource = dv;
I then load the datatable with my rows, and this is...

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.

I have an application in which it would be VERY beneficial if I could obtain
the names of the colums in a datagrid.
For example
dim datagrid1 as new datagrid
datagrid1.datasource = (stored procedure that loads datagrid)
datagrid1.databind()
I am able to obtain the data in the datagrid by its relative number however

Is it possible (and how?) to get the data grid column name
based on the DataGrid.CurrentCell?
The DataGrid has assigned a TableStyle comprising
selected columns (DataGridTextBoxColumn) from
the source DataTable (DataGrid.DataSource=DataTable).
I would like to be able to get the column name of the
datagrid based on the DataGrid current cell so I can reference
the appropriate column in the source DataTable.

I have a datagrid that is two levels down from the dataview (i.e.
grandchild). I have spent 3 hours trying to get the syntax of determining
it's real datasource (i.e. not it's source based on it's relationship with
the dataview).
argh!

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,...
