Getting time format in datagrid

[Sebastian Santacroce]

I'm trying to format datetime column in datagrid to a time
format rather than date. I'm using code:

Dim myGridTextBoxColumn As DataGridTextBoxColumn = New
DataGridTextBoxColumn()

myGridTextBoxColumn = CType(datagrid.TableStyles
(0).GridColumnStyles("StartDate"), DataGridTextBoxColumn)

myGridTextBoxColumn.Format="hh:mm:ss tt"

However, that last line always give error"Object reference
not set to an instance of an object."

What am I doing wrong?

Thank you

Sebastian

Hi,

Dim cm As CurrencyManager = CType(Me.BindingContext(dvClient),
CurrencyManager)

Dim pd As PropertyDescriptor = cm.GetItemProperties()("AppointDate")

Dim colDate As New DataGridTextBoxColumn(pd, "t")

With colDate

..MappingName = "ApointDate"

..HeaderText = "Date"

..Width = 100

End With

I tryed to apply this to what I have but it did not do
anything. Heres the code I used in reference to my first
email trying to merge with your code.
'ds is the dataSet
'StartTime is the field column name I want as time not
date.

Please clarify were I went wrong.

Thank you.
Dim cm As CurrencyManager = CType(Me.BindingContext(ds),
CurrencyManager)

Dim pd As System.ComponentModel.PropertyDescriptor
= cm.GetItemProperties()("StartTime")

Dim colDate As New DataGridTextBoxColumn(pd, "t")

With colDate

.MappingName = "StartTime"

.HeaderText = "StartTime"

.Width = 100

End With
