*User control code:*
<ValidationProperty("Value")> Partial Class UserControls_DateTimePicker
Inherits System.Web.UI.UserControl
Dim SelectedDate As Date
Public Event SelectionChanged(ByVal sender As Object, ByVal e As EventArgs)
Protected Sub CalenderImageButton_Click(ByVal sender As Object, ByVal
e AsSystem.Web.UI.ImageClickEventArgs)
Handles CalenderImageButton.Click
Me.UserCalendar.Visible = True
End Sub
Protected Sub UserCalendar_SelectionChanged(ByVal sender As Object, ByVal e
As System.EventArgs) Handles UserCalendar.SelectionChanged
Me.DateTimeTextBox.Text = Me.UserCalendar.SelectedDate
SelectedDate = Me.UserCalendar.SelectedDate
Me.UserCalendar.Visible = False
RaiseEvent SelectionChanged(sender, e)
End Sub
Public ReadOnly Property Value() As Date
Get
Return SelectedDate
End Get
End Property
End Class
*compair validator markup code:*
<asp:CompareValidator ID="CompareValidator3" runat="server"
ControlToCompare="DepartureDateTimePicker" ControlToValidate
="ReturnDateTimePicker"
Display="None" ErrorMessage="Date must be greater than today's date"
Operator="GreaterThanEqual" Type="Date">Date must be greater than today's
date</asp:CompareValidator>
if i set the ControlToCompare,ControlToValidate to the id of the user
control then validation didn't work but if i set the property to the text
box as:
ControlToCompare="DepartureDateTimePicker:DateTimeTextBox" ControlToValidate
="ReturnDateTimePicker:DateTimeTextBox"
it works but the problem is when the validation fails and i click on the
image button again to select another date it didn't display Calender
control. I am doing a ASP.NET course and i am not allowed to use third party
controls. so please help me.
thanks in advance.
