Hi everybody,
I have a datatable which contains 3 rows 'Project', 'Start Date' and 'End Date'. And I have two text boxes 'Min Days' and 'Max Days'. Now I have to filter the datatable so that I get the 'Project's which have a duration('Due Date' - 'Start Date') greater than 'Min Days' and less than 'Max Days'. I want to use the DataView.Rowfilter property. Please reply as soon as possible.

Thanks & Regards,
Srivikas.

Solution 2

Let us say
dv is your dataview then you specify
dv.RowFilter = "(Date Difference) > Min Days and (Date Difference) < Max Days"

Hope this is helpful.

Solution 3

You must calculate date diff at procedure level follow this link

http://victoriayudin.com/2008/10/27/sql-server-how-to-get-date-differences/[^][]

C#

dv.RowFilter = "difference  > " minDays + " and " + "difference  < " + maxDays;

Question is why you are not using Linq?
Thanks

Actually I am using this in a Sharepoint web part... How can I calculate the Duration in the rowfilter.
