I'm loading data from my database into a DataTable, and one of the columns is a date field.
[Code]....
I'd like to format that column so that instead of containing a full date, it will be formatted like "MM/DD/YYYY".
I've tried looping through each row in the table and changing the cell for that column, but I get an error saying that the string isn't a valid DateTime object.
I tried changing the column DateType to a string, but I get an error saying I can't change the DateType after the table is filled.
How can I do this? This seems like such a simple thing, but I'm having so much trouble with it.
If I am passed a datatable and I cant change the column structure..is there anyway to set an existing column to a Primary key so I can easily Find() the row I am looking for?
I have a DataSet comprised of two DataTables. One of the DataTables is further comprised of the results of two different SQL calls. I need to alphabetize the results of those SQL calls. After the seconds set of results is added to the DataTable I tried the following but the end result (displayed on the page) did not alphabetize the returned results. There was no error. Can anyone advise me please. 'programs' is the DataTable name, title is the column name.

I am reading a datareader, populating a datatable and then when finished populating I bind to a gridview. Right now, I am placing a literal in the cell of the rows based upon date differences....sort of a textual gant chart. What I want to be able to do is change the background color of the cell I am putting these literals in. I am including the code below where I am populating the cells with the text. Does anyone know how to make the background color change? I know that in a normal gridview on datarowbind I can change it but I don't know how to do this on a cell by cell basis within the code I have below.
I have a gridview bound to a SQL Select statement. I want the binding of one of the columns to depend on one of the values in the database record. For example, say I have a SQL table containing FirstName, LastName, ShowFirstName.
I want a the Name column in my Gridview to be bound to FirstName if ShowFirstName is 1, and bound to LastName if ShowFirst Name is 0.

I then DataBind my GridView to the DataTable. (so far so good) When I run the page I do see the GridView and the single row of data. However the checkbox shown is not enabled, meaning the user cannot uncheck or check it. (As if was not enabled)
