John,
I use a class with 1 shared method named Format to format a datagrid at
runtime with data from a datatable. The Format method formats any datetime
columns to display the date and time. You might be able to modify the code
for your needs.
Note that the code is compiled with Option Strict OFF, so you might need to
do some type casting if you compile with Option Strict ON.
Here is the code:
Public Class GridFormatter
Public Shared Sub Format(ByRef grd As DataGrid, ByRef dt As DataTable)
Dim ts As New DataGridTableStyle()
Dim tc As DataGridTextBoxColumn
Dim dc As DataColumn
For Each dc In dt.Columns
tc = New DataGridTextBoxColumn()
tc.MappingName = dc.ColumnName
tc.HeaderText = tc.MappingName
If dc.DataType Is GetType(System.DateTime) Then
tc.Format = "MM/dd/yyyy hh:mm:ss"
tc.Width = 125
End If
ts.GridColumnStyles.Add(tc)
Next
grd.TableStyles.Clear()
grd.TableStyles.Add(ts)
grd.DataSource = Nothing
grd.DataSource = dt
End Sub
End Class
Call the Format function like this:
GridFormatter.Format (myDataGrid, myDataTable)
