ValueChanged Code Isn't Triggered Until Have Set All Values Of Datetimepickers?
Nov 22, 2010
I have a load sub with a few declarations isorry for thn it as so: [code] But when the TimeFrom_dtp.ValueChanged code is executed, the Time From_dtp.Value isn't correct as it hasn't been set yet. If I change it round so the TimeTo_dtp.Value is set first then that doesn't work because the TimeFrom_dtp hasn't been set yet? How can I get it so that the ValueChanged code isn't triggered until I've set all the values of my datetimepickers?

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?

I have the following functions in my ProceduresControlller:
Function Add(ByVal bpid As Integer) As ActionResult
Return View(GetAvailableProcedures(bpid))
End Function[code].....
I'm loading the Add dialog via jQuery like so:
$("#dialog").load(
"/Procedures/Add",
{ bpid: 123 }[code]....
This is failing because it's calling the Post method (where "covered" can't be empty) instead of the Get. I tried decorating the Get with <AcceptVerbs(HttpVerbs.Get)>, but it doesn't change the outcome.how do I get it to use the Get? I realize I could change the names to not be ambiguous, but I want to know why it won't pick the Get if I'm only passing "bpid".

About some coding in visual basic.NET 2005. I was wondering if it was possible for code to be altered automatically if a certain event was triggered. For example; would it be possible for you to alter the following structure, say if a a button was pressed?
The structure is as follows:
Structure ClientDrawings
Public ClientID As String
Public Drawing_1 As String

I'm not even sure what I need to know. None the less lets say I got a timer with an if event to check if said event is triggered then it fires off some code. The problem is if said event is triggered it keeps firing off the code and I only need to do it one time. Whilst letting the timer keep checking if event happened. I hope I worded that right and here is a rough translation in code. [Code] Is there a way to keep checking if an event happened and only fire off the code one time?

I'm making a form with an overview of orders from our clients. I have inserted 2 datetimepickers so the users can choose a period.
To know how many cols I need in my grid, I need to know how many months there are between the 2 datetimepickers. But that seems to be the problem. How do I get the number of months starting from one datetimepicker untill another.

I have four datetimepickers. (datefrom, dateto, timefrom, timeto) 2 that allow the user to select a date from and a date to (at the minute these work okay) and 2 that allow the user to select a time on that day that they have previously specified (at the minute these don't work)
What I would like is to allow the user to be able to select any time between 01 Jan 2000 and now.The timefrom time cannot be higher than the timeto time if the 2 date selects are equal.The timeto time cannot be higher than the current time if the dateto selected is the current day.There's also an interval of 15 minutes. So, if the days are the same, the time cannot be within 14 minutes or less of each other
Also, something that happens is, when the code executes. I change the timefrom so it equals 00:00 and the timeto so it equals 00:15. When I press the down arrow the change the timeto to 00:14 the timefrom changes to 23:59.

I want to update the date and time from two separate pickers to my table.My 2 DTPers are bound to a dataset.One is in the Short Format, the other is Time.I have several other bound controls, and I just do a .Update to update my table. I tried just updating the row:
Me.DsTradeShow1.Tables("Tradeshow_Details").Rows(0).Item("Show_Date") = CDate(Me.DateTimePicker15.Text & " " & Me.DateTimePicker16.Text)
but it throws an exception when I do my save.

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 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.

The bottom line on a dropped-down datetimepicker shows the date different then in the text-part.In my case, the text-part format was yyyy/mm/dd, but the bottom part of the dropped down part stated Today: dd/mm/yyyy, what is probably the format set in the regional settings.

I am using VS 2008 and UltraGrid from Infragistics v 5.2
I have two UltraGrid objects on a Winform. While the AfterRowUpdate event gets triggered for one, it does not get triggered for the other. Here's the procedure of the offending UltraGrid event:
This does get executed:
Private Sub ugPatient_AfterRowInsert(ByVal sender As Object, ByVal e As Infragistics.Win.UltraWinGrid.RowEventArgs) Handles ugPatient.AfterRowInsert
e.Row.Cells("Courtesy_C").Value = "Mr."

I'm having a really annoying issue which I can't get to the bottom of. I've got a NumberUpDown control which has a ValueChanged event. There is only one reference to it in my entire project which I have commented out to prove that it isn't calling the event. Even though the number is not being changed (the control sometimes isn't even in focus!) the ValueChanged event gets called. This is driving me crazy and I wondered if I could back track through the code to see what actually caused this event to trigger?

Protected Overrides Sub OnMouseWheel(ByVal e As System.Windows.Forms.MouseEventArgs)
MyBase.OnMouseWheel(e)

The event is raised normally in the form containing my control. why this could be, or better still, how to solve it?

My problem is, I have set the parameter to be 150 in the database. and the alert triggered should refer to the parameter value. if the calculation result exceeds the parameter value, it will turn the box to red colour. however, i notice that it only compares the first three number. for example, if the calculation result is 1778.99 it will turn the box red because its first three digit is more than 150. but if the calculation result is 10234.90, it does not trigger the alert. i assume it only takes the first three digit.
Here is the code for this part;
Dim total1 As Label = CType(e.Item.FindControl("total1"), Label)
total1.Text = e.Item.DataItem("inventories").ToString * 365 / e.Item.DataItem("operating_cost").ToString
