Try
If IsDate(FieldName) Then
Dim actualDate As DateTime = CDate(FieldName)
Dim DtLicExp As DateTime = CDate(actualDate.ToString("d", Thread.CurrentThread.CurrentCulture))
FieldName = DtLicExp.ToString("MM/dd/yyyy")
Return True
End If
Catch ex As Exception
'FieldName &= "Format must be MM/dd/yyyy"

End Function
validate this date string formate to datetime.

I have a detailsView whose date values in a cell are currently being displayed in longDateFormat, i want to convert all date values in this DetailsView to short date.
For example, instead of 6/1/2010 12:00:00 AM, i want to display just 6/1/2010
For a Gridview, i can achieve that by the code blow
Protected Sub DetailsView4_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles DetailsView4.DataBound
If e.Row.RowType = DataControlRowType.DataRow Then
For i As Integer = 0 To e.Row.Cells.Count - 1
Dim cellDate As Date
If Date.TryParse(e.Row.Cells(i).Text, cellDate) Then
e.Row.Cells(i).Text = String.Format("{0:d}", cellDate)
End If
Next
End If
End Sub
How can achieve the same with a DetailsView?

View 5 RepliesI have an item template field retrieving a date field from an Oracle 11g database that can be null. The date is converted to a string before binding to the gridview. When the column is sorted is is being sorted as a string. I have read in several places if you add a formatting string to the eval statement in the item template that the sort operation will then sort the string as a date. However, I cannot get it to work. I also tried a bound column, but the column is still being sorted as a string.Code from the aspx page:
<asp:TemplateField HeaderText="Comp Date">
<HeaderTemplate>
<asp:LinkButton ID="sortDatea" runat="server" CommandName="Sort"

Sub SubmitBtn_Click(Sender As Object, e As EventArgs)
If Radio1.Checked Then
Label1.Text = "You selected " & Radio1.Text
ElseIf Radio2.Checked Then
