I am trying to fill a textbox value with the current date and I do not want the user to be able to change the date. I want to use a textbox and not a datepicker. I would like the form to load with today's date already loaded in the textbox, which I will then use in my insert query.
I want the date format of yyyy-MM-dd to be in the textbox memberregisterationdate.text. I am not sure where on my form I should put the code either.
Really stuck on this and I can't seem to find it anywhere
Thanks in advance
You have to make it Enabled = False to disable it. You can load it in Form_Load:
memberregisterationdate.Text = Date.Today.ToString("yyyy-MM-dd")

Currently I am working with Data Gridview and Datetime picker in VB.Net
And dont know how to pass the value from gridview to date time picker. please help
Below is Date Colume of gridview
This error occured after debug
I tried some code...
Student_Admission.DateTimePicker2.Value = CDate(DataGridView1.CurrentRow.Cells(1).Value)
in the first code you are converting to date then ToString. The value of DTP obviously cant hold that. To adjust the format you need to add a .Format property
The second code you supplied should work assuming there is a value that can be a date in cell(1) of the current row
Edit. ok, so you're not actually calling .ToString("mm/dd//yyyy") you are actually expecting the value to format as such? that's not going to work either.
So, I am using the datetimepicker by eonasdan. Everything appears to work fine except one field.
The field in question clears the input box that the date is in. Why does it not stay there?
I have tried the options defaultDate and useCurrent, but nothing seems to make a difference.
Here a sceenshot of my form:
I am currently using Microsoft Visual Studio Express 2013 for Windows desktop with an SQL back-end. I am trying to run an SQL query that will have the date time in format "yyyy-mm-dd." My problem is I need to see all entries from that date. Currently my date time picker keeps giving me a time with my selection. I need to remove the time portion. I tried a couple of solutions from the web but when I try and display the date time picker in a message box to see what the value is it says false. I am not sure how to change the output value in the custom field to remove this. Here is my code.
This is in on my load event:
'date time picker set up
DTPPromiseDate.Format = DateTimePickerFormat.Custom
DTPPromiseDate.CustomFormat = "yyyy-MM-dd"
Then in a button click event, is a message box to display what was selected in the date time picker. I want to get my message box working correctly before I try and run SQL queries with it.
MsgBox(DTPPromiseDate.Value)
-------------------------UPDATE-----------------
This code appeared as I wanted it to but I am still trying to work it into my query.
DTPPromiseDate.Value.ToString("yyyy-MM-dd")
Apply the formatting string that you used in the picker's custom format to the message box text as well.
I am trying to store DoteOfBirth from a Calender control in visual studio 2010.
Dim dob As Date = Calendar1.SelectedDate.Date.ToShortDateString()
I wanna save like dd/MM/yyyy without anything else but when i save it it shows like
2012-02-28T00:00:00+00:00
I don't know where to change the format and I don't know how to remove the thing attached to the date. I am writing it in vb.net and saving to xml file.
Thanks so much.
If you're using a DateTimePicker control, you should use the Format or CustomFormat properties.
If you're using the MonthCalendar control ... well, you may consider using the DateTimePicker instead, as per this excerpt from MSDN:
If you need custom date formatting and a selection limited to just one date, you might consider using a DateTimePicker control instead of a MonthCalendar. Using the DateTimePicker eliminates much of the need for validating date/time values.
I have a datepicker in a vb.net clickonce application. I need to make sure that in order to use the application that selecting a valid date is required. Ideally, I would be able to set the value of the datepicker to null and then programatically create Try Catch logic based on datepicker1.value still being null. Unfortunately, it will not allow me to assign a null or blank value to the datepicker. I cannot create my logic based on any real values of the datepicker because who's to say the value picked is not valid. I've tried setting the value to some outrageous date that no one would pick for the application like 1/1/1970, but then the datepicker opens up at 1/1/1970 and drops that date in as soon as it gains focus. I need a way to validate whether or not someone has selected a date, but am stuck and can't find any real help online. I am not looking to set the customformat = "", so please do not respond with that solution. I need the actual value to be blank or something I can run validation against to know that the user has in fact selected a date.
Set the ShowCheckBox property to true. That will make the control look like this...
When the user selects a date, it will check the checkbox. Then when you need the value...
If datePicker.Checked Then
'user has selected a value
Else
'user has NOT selected a value
End If
Can you use the ValueChanged event to set a flag to tell you they've clicked on a date?
UPDATE
You could also use the OnClick method to set a flag to verify the user actually clicked on the DateTimePicker.
