Question

"String was not recognized as a valid DateTime."

Asked by: PHD

DataView view = new DataView(data.syn_vAllActions);
          view.RowFilter =
               "heure_rdv>=#" + celldate1.ToString() + "# and heure_rdv<#" + celldate2.ToString() + "# and heure_rdv2<=#" + celldate2.ToString() +"# and heure_rdv2>#" + celldate1.ToString() + "#" ;


Now I got this message.

I think this is  from the format of the date ...

the problem is that I don't know the date format of the server where I will deploy the application. It is not the same as the server of development.

thank you,

Thank you,

just for reference, hash in the row filter is correct as it is recoginising you are trying to supply a DateTime now. So I would have thought we need to get this into the correct format in order for it to recognise as much.

 

by: REA_ANDREWPosted on 2007-01-17 at 03:08:11ID: 18331113

ok well Can you ouput the string again for us to take a look at to see if there is any bisible format errors?

 

by: REA_ANDREWPosted on 2007-01-17 at 03:10:41ID: 18331120

try this

               "heure_rdv>=#" + Convert.ToDateTime(celldate1.ToString()).ToString("yyyy MM dd HH:mm")+ "# and heure_rdv<#" +  Convert.ToDateTime(celldate2.ToString()).ToString("yyyy MM dd HH:mm") + "# and heure_rdv2<=#" +  Convert.ToDateTime(celldate2.ToString()).ToString("yyyy MM dd HH:mm") +"# and heure_rdv2>#" +  Convert.ToDateTime(celldate1.ToString()).ToString("yyyy MM dd HH:mm") + "#" ;

I am now putting these dates into the format yyyy MM dd HH:mm

so for example

2007 01 17 11:10

 

by: REA_ANDREWPosted on 2007-01-17 at 03:11:04ID: 18331124

or try separating the date values with a dash too

 

by: PHDPosted on 2007-01-17 at 03:11:54ID: 18331134

The string looks like this :

"heure_rdv>=#15/01/2007 8:00:00# and heure_rdv<#15/01/2007 8:30:00# and heure_rdv2<=#15/01/2007 8:30:00# and heure_rdv2>#15/01/2007 8:00:00#"

 

by: REA_ANDREWPosted on 2007-01-17 at 03:23:03ID: 18331192

I mean a more elegant approach would be this

String.Format("heure_rdv>=#{0}# and heure_rdv<#{1}# and heure_rdv2<=#{2}# and heure_rdv2>#{3}#",new object[]{Convert.ToDateTime(celldate1.ToString()).ToString("yyyy-MM-dd HH:mm"),Convert.ToDateTime(celldate2.ToString()).ToString("yyyy-MM-dd HH:mm"),Convert.ToDateTime(celldate2.ToString()).ToString("yyyy-MM-dd HH:mm"),Convert.ToDateTime(celldate1.ToString()).ToString("yyyy-MM-dd HH:mm")});
