I have the below code, data is bound to the grid. All the filters work great except GridDateTimeColumn filters - for some reason the filters do not respect the values that I feed into the text box. eg: if I put in 6/10/2009 and choose equal to - I get no rows. Can Someone please tell me why ? I used to use GridBoundColumn for the date , the filter seemed to work but the problem was when users enter 06/10/2009 , it would not convert it back to 6/10/2009. For this reason I changed it to GridDateTimeColumn and now the filters do not work at all. My version of the controls is 2008.3.1314.35.
