I'm having a hard time sorting my dataset / data bound grid a a Time column. My backend are SQL server / IIS ISAPI dll. The "problem columns" is a SQL server Time column. It comes sorted on that time columns from the server and shows perfectly in the grid. Once I insert a new record on the client I want it to sort the grid / dataset based on the time column. However, when I try to set sort order (Ascending) on either the grid column or using the Sort function on the data set, it always puts it on the bottom last row.

My only solution until now is to create a new calculated field in the dataset and assign the time value as a string. Now, when sorting on that column, it works perfectly.  Please see the two attached pictures. The pictures named "Sort on Time" shows that the newly inserted row is on the bottom and you can see sorting is active on the first column. On the second picture, "Sort on String" you can see the new row sorts perfectly.

Can this be SQL server related? Just as a side note, in the Database Manager in the IDE, I'm unable to use Time fields in any query there. If I try to select or order by any Time fields there I get: "Dataset Open error: Arguments are of the wrong type, are out of acceptable range, or are in conflict with one another." PS. I only use the Database Manger to test my queries and get the fields defs set up.

Anyone else seen this before?

Thanks

How are you generating the JSON on the server side ?

The JSON is generated by the TEWBDataSetAdapter in the ISAPI dll

Okay, the issue seems to be that the date/time values coming from the server side include odd date portions for times, and vice-versa for dates (times can contain odd values), so I've added functionality in the dataset loading to strip out the invalid portions of both so that they can be sorted properly in a binary fashion.

This fix will be in build 15.

I'm still looking into the SQL Server time issue.

Not sure what the SQL Server time issue is - I have had issues in the past where I needed to make sure the SQL Client was installed on the machine where my programs run(including my ewb web server).  When SQL Client not installed newer data types like date and time did not format in queries as expected.

That's a good point.

Eivind - which SQL Server client are you using ?
