When is a column not a column?
I have several extremely similar datawindows that I have to maintain that go
against the same table. Recently, I had to add a column to that table, and
also add the column to ALL of these datawindows that go against this table.
I added the column to the first datawindow, set up the edit control style,
etc. I then did a copy/paste of the columns edit control to the remaining
dw's (of course remembering to first add the column in SQL). Everything
(update props, column specs, column props) seems to indicate that the pasted
column is linked to the column I selected, HOWEVER, when I...[*-)]how to delete all columns except one column for the corresponding column name......?

I have a GridView and would like to access the data value of a certain data column. I know that I can access the column with the Cells property plus the index of the column. But I would rather access the column by its name since this is safer in case of row reordering. I there a way that I can do that? Or how can I get the index of a column by specifying the column name?
AFAIK There's no direct way to access the GridView columns by name, but if you are using BoundFields (or others type of DataBoundField controls) you can make a method to return the index

I need to consolidate columns of data available across different
directories into a single excel csv file. Usually we write to a file
row after row but for the current task I have, it would be convenient
to write the file column after column. Is there a file writing mode
If not, I guess, I will have to write the matrix row by row and then
take a transpose. Let me know what you guys think and if you could
share some skeleton of code for something like this would be great.

HiI already bind a DataGridView to a databse. My DataGridView is showing column names as it is in the table. I want to show user-friendly column names in the grid instead of column names in the database table. Please help me in this reagard. Thanx in advance
Your statement indicates to me that your columns are dynamically added to the grid, that's why it's showing the database column names.
You can show user-friendly column names by changing your query like so:
SELECT fName as 'First Name' FROM Users.DarmarkMark as Answer, if this reply answers your post.

I need to locate the identity column for a DW. Only method i see is use of
the columnName.Idenity property - which requires you to traverse all the DW

Is there a way just to get the identity column directly - or the Primary

I've got a common experssion that I'd like to put on every
bold column property: I'd like set the column font to bold
if the previous column value is equal to the current. As I

name in order to set an expression like this: "if (col_name
= col_name[-1], ...)"
So any idea?

Just like the title says, I'm trying to set a column to invisible but I'm unable to do so.
If I bound the column I can used the code:
me.datagrid.Column.Item(1).Visible = False
But since I'm wanting the column NOT to be bound (there are a number of sql scripts that populate the same datagrid so I cannot bound all the columns since the columns are different for each script etc etc etc) how do I set an AutoGeneratedColumn to invisible??
