Dim pDate as Date
Dim dteDay, dteMonth, dteYear As Integer
dteDay = Day(pDate)
dteMonth = Month(pDate)

CssClass="pastdatepicker"
Text="DateOfReceiving" />

I add a date picker as follows
Friend WithEvents dtpReportDate As System.Windows.Forms.DateTimePicker
The default date picker has left arrow and right arrow which allow you to browser previous month and following month. I add a handler to date picker valuechanged event:
AddHandler dtpReportDate.ValueChanged, AddressOf dtpReportDateChanged
Private Sub dtpReportDateChanged(ByVal sender As Object, ByVal e As System.EventArgs)
'do something here
End Sub
The problem is that whenever I click left arrow or right arrow to change month, the dptReportDateChanged is triggered. I do not want this happens. All I want is that after I find a month, I double click date to trigger the event.

I have a VB 2008 application with multiple DataPicker fields. The data is binded to SQL database. On the form load I set the checkBox for each date to false if there is no date in the field. Noticed that if I make changes to some dates for record 1 in the table, save it and scroll to the next record - I see the date that I just changed for record 1 - also on records 2 and 3. Why is it happening? I don't have that problem if I use text fields to display the dates. I had encountered the same problem with different project and just switched to text boxes. With this new project?

However the items in the list that the listbox is bound to are not all String types. Some are DateTime and a few are Integers. I would like to have a datetimepicker displayed instead of a textbox for the DateTime types. How can I make this happen.To clarify some points the list is populated at runtime using reflection so I don't know which fields are what types ahead of time.

View 4 RepliesI've been asked to add in some functionality to an existing project.On the main form is an unbound DataGridView. I've been asked to add in a column for a date. Easy enough to add in the column, however I would like to make it easier on the users & have a date picker in the column instead of having it as a free text field & then have to apply constraints to ensure I get the date in the correct format.I've not been able to find anything on this in the usual places & am hoping someone on the forum might have some ideas I could try ?
View 3 RepliesI am using vb.net express version. I have a datagridview which is popuated with data from an access database. I have all the data side working ok with the "Call Date" column set as datetime and sorted in date order assending within my application. I also have a monthviewcalender on the form and wish to filter the datagridview by the date selected in the monthviewcalender to show appointments i may have on that date.I have tried to populate the selected date into a textbox and use the following to filter:
AppointmentsBindingSource.Filter = String.Format("[Call Date] Like '" & TextBoxDate.Text) & "*'"
This causes a error. I have tried many different variants like:
AppointmentsBindingSource.Filter = ("[Call Date] Like '" & MonthCalendar1.SelectionRange.Start) & "*'"
The column is set as datetime in access and is system.datetime in the database explorers properties.
