Try giving

{D} or {d} in the formatting column

 

by: surajgupthaPosted on 2004-11-03 at 22:21:27ID: 12490585

{D} or {d} should be in the Data Formatting expression. It can be added for a bound column in the property builder. which in HTML looks like
<asp:BoundColumn DataFormatString="{D}"></asp:BoundColumn>

Otherwise it can be done in the Item Data Bound event of the datagrid

Hi There,

What would the syntax be?

c.Controls.Add(New LiteralControl(dataR(dataC.ColumnName)))

by: surajgupthaPosted on 2004-11-04 at 00:17:41ID: 12491047

Hi Bullrout,
             I dont know how to add a DataColumn at runtime as you have done.

Check if there is an attribute called DataFormatString for DataC.

Regards,
Suraj

 

by: raed_hasanPosted on 2004-11-04 at 04:02:49ID: 12492640

Hi
 In grid properties on your column you there is a field Named
DataFormatString and you can make your format as follow :
{0:dd/MM/yyyy HH:mm}
be carefull  mm = minutes and MM = month

 

by: raed_hasanPosted on 2004-11-04 at 04:08:05ID: 12492685

Oops surajguptha  I didnt notice that u mentioned DataFormatString in ur reply , sorry.

Regards

 

by: ryerrasPosted on 2004-11-04 at 06:20:21ID: 12493732

If I assume dataC.ColumnName returns the date, then

c.Controls.Add(New LiteralControl(dataR(dataC.ColumnName.ToString("d")))

 

by: bullroutPosted on 2004-11-04 at 16:56:20ID: 12500213

Hi There,

I tried the code above "c.Controls.Add(New LiteralControl(dataR(dataC.ColumnName.ToString("d")))" with no luck. The database table is a datetime datatype, do I need to explcitly declare the column inside the datatable as this datatype too?

Sean

 dt.Columns.Add("wipdue")

 

by: ryerrasPosted on 2004-11-04 at 17:57:50ID: 12500543

sorry I guess I put the parenthesis in the wrong place. try with the following one more time
c.Controls.Add(New LiteralControl(dataR(dataC.ColumnName)).ToString("d")));

 

by: bullroutPosted on 2004-11-04 at 18:20:00ID: 12500711

Hi There,

I get the error, public overridable function() as string has no parameters and it's reutrn type cannot be indexed.

Help!

 

by: ryerrasPosted on 2004-11-04 at 18:33:36ID: 12500779

Hmm how about this
c.Controls.Add(New LiteralControl(CType(DateTime, dataR(dataC.ColumnName)).ToString("d")));

 

by: bullroutPosted on 2004-11-04 at 18:37:56ID: 12500793

still no joy, it complains about not using the datetime as an expression, and the ctype clause make the program not recognise the datacoloumn.

 

by: mmarinovPosted on 2004-11-04 at 22:13:10ID: 12501667

i think ryerras makes a little mistake
try this

c.Controls.Add(New LiteralControl(CType(dataR(dataC.ColumnName), DateTime).ToString("d")));

B..M

 

by: vardiumPosted on 2004-11-05 at 04:15:35ID: 12503465

c.Controls.Add(New LiteralControl(Format(Cdate(dataR(dataC.ColumnName)), "dd.MM.yyyy")))

and take a look at this article

by: bullroutPosted on 2004-11-05 at 16:00:54ID: 12510192

Hi All,

The code changes seemed to have got rid of the error but the format of the date does not change.

if I use this c.Controls.Add(New LiteralControl(CType(dataR(dataC.ColumnName), DateTime).ToString("d")));

I still get this:

03/07/2004 12:00:00 AM

if I use this c.Controls.Add(New LiteralControl(Format(Cdate(dataR(dataC.ColumnName)), "dd.MM.yyyy")))

I still get this:

03/07/2004 12:00:00 AM

Any idea why the formatting is not taking effect?

 

by: ryerrasPosted on 2004-11-05 at 16:19:37ID: 12510270

what do you want the date format should be

 

by: bullroutPosted on 2004-11-05 at 16:41:35ID: 12510367

Hi there,

I just want the date format to be (03/07/2004).

 

by: ryerrasPosted on 2004-11-05 at 16:44:04ID: 12510384

ok then use this

c.Controls.Add(New LiteralControl(CType(dataR(dataC.ColumnName), DateTime).ToString("MM:dd:yyyy")));

 

by: bullroutPosted on 2004-11-05 at 16:55:09ID: 12510427

I have tried this and with not luck, it does not make a difference to the format at all.

 

by: ryerrasPosted on 2004-11-05 at 17:00:08ID: 12510446

do one thing, try with different formats like ToString("C") , ToString("F") and ToString("R") , see if the result is the same. Then there must be something wrong somewhere else, not when you are adding the control. Let us know if you are getting the same result

 

by: bullroutPosted on 2004-11-05 at 17:07:08ID: 12510466

sorry ryerras, my mistake :)

It's working well now, I appreciate the help.

Sean

 

by: ryerrasPosted on 2004-11-05 at 17:10:17ID: 12510478

cool. thats great to hear

 

by: mmarinovPosted on 2004-11-05 at 22:40:14ID: 12511801

also you can use

CType(dataR(dataC.ColumnName), DateTime).ToShortDateString()

What if you are creating the data table like so:

DataTable finalStatement = new DataTable();
finalStatement.Columns.Add(new DataColumn("Date", typeof(DateTime)));

how would you format the column now?
