I am creating a datatable and then adding a column to it which is filled with data from existing column and parsed into correct format DateSold is my existing column from my datafile and I create NewDateSold by adding the column to the existing table and then parsing the information in date format.

This is added to a binding source which then is used to populate a combobox I want to be able to sort the combo box by NewDateSold Desc I was able to this on the original column by simply using the "order By" in my query, it seems now that I added new column it is no longer sorted?

Sep 3, 2009

So I made a little program, and when I run it on my computer the Date format displays as DD/MM/YYYY, but when I run it on some other computers it displays as MM/DD/YYYY.

.net - Sort Datatable / Dataview / Gridview Of Files Based On File Modified Date

Aug 2, 2010

I have a page which lists all the files in a particular folder (all PDFs), using a data-table and gridview. I'm currently sorting this table by the filename (by using a dataview), which isn't that helpful, and I want the gridview of files sorted by the file created or file modified date (as recorded in Windows). If that's not possible, a second option would be to extract the date from the file name string (no problem doing that), and sort the dataview/datatable or gridview based on that.

VS 2010 - DataTable Visualizer (Date Not In Correct Format)

Nov 28, 2011

I have an SQL Database which has some end dates. I have used this little statement to make sure that the dates come out of the database in the right format
Execute("Set dateformat dmy")

And I use the below statement to enter the data in to a datatable and, with the above command, when I go to look at the data in datatable visualiser the dates seem to be in the correct dd/MM/yyyy format
"SELECT CID, expdate FROM Traineecerts WHERE iscurrent = 1"
Now when i try d1 = row("expdate") the format changes to the american MM/dd/yyyy format

Please note d1 refers to a variable with the type of date. Even if I format the dates after using d1 = format(row("expdate"),"dd/MM/yyyy") they don't change unless I make d1 a string. Is this normal?

Format A Date Column In A DataGrid From Program?

Mar 31, 2011

I have a .aspx file with a datagrid in it[code]...

The .aspx.vb file associated with it fills it in with a datagrid object.[code]...

That all works fine. However I want to format one of the columns with a particular date format. Is there a way of doing that in the vb code? I know I can do it in the .aspx by specifing AutoGenerateColumns="False" and then explicitly defining the columns, but I want to do it in the code as it's more future proof for my application.

I would like to have a child form that contains a list of columns associated with the datatable that contains a checkbox that will allow the user to hide and show the columns ( I do not know the best control to use here) (I assume this is the easy part as All i need to do is loop through each of the datatable's columns to get the column name)

now I would like save these visible columns on some event like form_closing so that the next time the user opens the form up it will remember the settings
