Trigger Datepicker.valuechanged Event When Browsing Month In Date Picker?
Sep 13, 2011
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:
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 to select only month from a date picker Control. I know there is Date Format Property available for the same purpose and i am pretty happy with that.
The only problem is that when I open my date picker popup, the date picker calendar popup is in Month - Mode. Is it possible to be same on Year Mode. I need to allow the user to select the month regardless of the day of the month.
And Also, I don't want to display the inner date of calendar control which is placed just below on calender control.
Is there any way to override DateTimePicker or what would be the best way to reproduce the DateTimePicker behavior if this is not possible ?
I am using a datetimepicker control to record leave dates. Since i am developing the application for a Ghanaian organization, i found out there is the need for me to format the datetimepicker value to suite the users so that it will look like how Ghanaian usaully write their dates. So i have been able to format it perfectly by using this code
I changed the date of datetimepicker format to yyyy-mm-dd in custom format...but it displays 2009-00-22...the month part is not showing the month of the exact month..how to change the format of the date?
I have a main form that has a dynamically generated treeview and also a panel control. Depending on the selection made within the treeview the panel docks 1 of three diffrent usercontrols which are full sub forms(done for ease of modifing design of sub form rather than layering panels on top of panels).Upon button click withing usercontrol i wish to trigger event within main form.For example delete button wich then triggers to remove current selected node from treeview. code for 1 of three diffrent user controls
Dim ctrlQ As New QuoteUC(TrViewQuotation.SelectedNode) PnlSubFormDock1.Controls.Add(ctrlQ)
Code for delete button for which i need to raise event.
If MsgBox("Are you sure you wish to delete this customer ?", vbYesNo, "Delete Record") = vbYes Then Deletecustomer(n) End If
I have a combo box that on valuechanged event, a yes/no msgbox pops up asking the user if they want to save changes. but if they click no, i want to change the value of the combobox back to its original value. but the problem is that the valuechanged event fires twice. is there anyway to keep the event from firing?
I have a form containing 135 NumericUpDown controls (15 rows x 9 colums).I also have a Button control (btnCalc) that performs calculations per each row.btnCalc.enable=False for the most part and I only want it to be enabled if the value of any of the NumericUpDown controls change - i.e., to prompt user to recalculate.what is the best way to program this w/out having to code a "ValueChanged event" for each of the 135 controls?
Currently i have a ReturnSystemDate in a module, so that whenever i need the current date and time i call this method, however my data is saving as in 1 format and displaying in another. I have my variables set up as dateTime to store the current date and time, when calling System.dateTime.now.toString() i get 11/08/2010 Time, however when casting to Date as in CDATE() i get 08/11/2010 time. How can i stop this?
It looks like there is a bug in the DateTimePicker control, because I don't find any event specific for the changing the check state of the checkbox, only the ValueChanged event seems available. So that event should trigger every time the date in a dtp is changed manualy, or by choosing a date from the calender or when the checkbox in the dtp is checked or unchecked by clicking on it, the event ValueChanged should be triggered. But it doesn't do that all the time.

I need to define weeks for my app. So I want to select a certain week of a month. then I want to tick the days that apply and save those dates to a table.
I am using VB.net as well as Jquery Datepicker for getting dates.
In my VB.net code <tr><td> DateOfReceiving: </td><td colspan="3"> <asp:TextBox ID="DateOfReceivingTextBox" runat="server" CssClass="pastdatepicker" Text="DateOfReceiving" /> </td></tr>
I want to allow enter user only todays date or past date with format dd/mm/yyyy. I want vb.net custom validation for that. How to write vb.net regular expression.
i am using date time picker and i am selecting 1 date from calender.after selection of that date i want to refresh date time picker i.e. it should display todays date.
I have an Sql server 2005 table called Emploeefl with 2 fields, EmployeeCode and Date of Birth. The data type for the date of birth is Datetime. I have a Date time picker on a vb.net 2005 form called dtDateOfbirth. When I click on the save button I get the error message "Conversion from string 'yyyy/MM/dd' is not valid. Below is the code
Dim newQE_Date As Date newQE_Date = Format(Me.dtDateOfBirth.ToString, "yyyy/MM/dd") 'newQE_Date = String.Format("2008/09/10", "yyyy/MM/dd")
The problem that I'm having is that when I try to select a different date, the text doesn't go away. That may make no sence, but let me tell y'all what I've done.
1: Created a GroupBox 2: Put a DateTimePicker in the GroupBox 3: Put TextBoxs in the GroupBox 4: Changed the DateTimePicker to look like this: A)Checked - False B)Allow Drop - True
I thought that if I changed that, then the text in the text box would go to that specific date. It didn't do that, it just stays the same. What I'm trying to do is enter text in say 3/7/11 and when I choose date 6/12/12 it will display blank text boxes for me to enter something different.
I have noticed that hwen i set the datetime programmatically on the wpf datepicker the writing "show calendar" does not disappear but remains visible underneath the date passed?is there a way to solve this problem
I have a date entered in from at DateTimePicker (dtDate.Value) and am writing it to an access database. This insert code works without the date, but not with it.
I am having a bit of trouble with using the date/time picker in a project.It is a program for calculating travelodge hotel accomodation prices. The price for a weeknight is 40 but weekends increase to �50.The code which I wrote is this:
For i As DayOfWeek = dtpArrival.Value.DayOfWeek To dtpDeparture.Value.DayOfWeek If dtpArrival.Value.DayOfWeek = 1 Or 2 Or 3 Or 4 Then PriceDecimal = PriceDecimal + 0[code].....
It does not work obviously because I am using the date/time picker for arrival date only. I think I need to use some other value which i would presume is something like "If DayOfWeek = 1 or 2 or 3...." but this will not work.
Eg. ""vb.net" timer event trigger on purpose". This application is meant to run at all times to download a web page every minute. To avoid freezing the UI, I read that the best solution is to move the code from a While/Sleep loop to a Timer that will be triggered every minute. The problem I have, is that the user must wait for a minute before the event is triggered:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Timer1.Interval = 60000 Timer1.Enabled = True
[CODE]...
Is it possible to force this event to occur instead of waiting for it?
I'm developing a finance software and I want the user to enter a bill and pick the due date via month calendar. I getting it to work was the easy part, but now I only want one month calendar, for each time a user enters in a bill and picks a date.every time the user goes to pick a due date I have to call one of the several I have on screen.Here is my code that I have so far:Add due date button:
I have create a Car Rental application, where, based on two DateTimePickers, the number of days and, by extension, the total cost of the Rental can be calculated. I managed to get my DTPs working without much problem, however, my Min/Max dates do not seem to function.
Also, I want to create a condition where if the user returns the car on the same day, they only pay 60 percent of the normal cost. I have a basic idea of how to do this, but, once again, I am not quite able to get it to work.
Here is my code:
Private Sub Calculate_cmd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Calculate_cmd.Click
'Declare Variables for DTP Calculations. Dim DatePicked As DateTime = Picked_dtp.Value Dim DateReturned As DateTime = Returned_dtp.Value Dim intPicked As Integer Dim intReturned As Integer Dim intDays As Integer Dim intRate As Integer Dim intTotal As Integer
' Set the MinDate and MaxDate. Picked_dtp.MinDate = DateTime.Today.AddYears(-1) Picked_dtp.MaxDate = DateTime.Today Returned_dtp.MinDate = DateTime.Today.AddYears(-1) Returned_dtp.MaxDate = DateTime.Today
'Read Data off of DTPs. intPicked = DatePicked.Day intReturned = DateReturned.Day
i have a problem on getting the values of it because of the same values such as the same parameter like @cdate_time_log, because i wanted to filter date through the use of date picker
Public Function _spselect_borrowerlog_fromto(ByVal cdate_time_log As String, ByVal cdate_time_log1 As String) As Boolean Dim cmd As SqlCommand Dim da As SqlDataAdapter
