I have set a specific format for a column in an Ultragrid. But still the DateTime is in its default format.
//Code
UltraGridColumn.Header.ToolTipText = Field.FieldDescription
UltraGridColumn.Format = "d"
Even after the above format is set the grid shows the value in the column as 06/06/2013 02:43PM
But the expected output is 06/06/2013
Why i'm getting this?
Added the column style as DateTime.
//Code
UltraGridColumn.Style = ColumnStyle.DateTime

When I am passing value from DataGridView to a DateTimePicker, I am getting this error
String was not recognized as a valid DateTime
and here is my code
Dateadd.Value = Convert.ToDateTime(DGVTest(0,DGVTest.SelectedRows(0).Index).Value)
Does this work?:
Dateadd.value = CDate(DGVTest(0, DGVTest.SelectedRows(0).Cells(0).value
It looks as if you code is just returning the value of the index of row (0), so just 0?
Do you need to get the date time value from a cell withing the grid view? The code you have written does not do that. In that case try:
Dateadd.value = CDate(DGVTest.Rows(0).Cells(0).value)
Let me know if this works for you.
I am reading data from a CSV file into a Sql table. Problem is some dates in a date column in the CSV would be empty. I am using the following code to convert the empty cells to NULL values. However I get the following error :Additional information: String was not recognized as a valid DateTime.Couldn't store in ANALISEDATUM Column. Expected type is DateTime
My code is :
Do Until parser.EndOfData = True
Dim data As String() = parser.ReadFields()
For i As Integer = 0 To data.Length - 1
If (String.IsNullOrEmpty(data(i))) Then
data(i) = DBNull.Value.ToString
End If
Next
datatabel.Rows.Add(data)
The error occurs at the last line.

I think, seems the format of the date adding to the table is wrong, please make sure the format of the table date column and csv file date value are same.
Ex: Table date format might be : mm/dd/yyyy
csv file date value format might be : dd/mm/yyyy
I have a function that returns an ODate (date in a double data type) from a called API.
Private Function CoreCompute(....)
....
CoreCompute = oXmlHttp.ResponseText //sample return: a double value 41902, which is equivalent to 2014/09/20
End Function
When this is called to a cell with a Format of Date, it is not transformed to a date value and not equal to a true date cell.
How can I output a value in a cell which can be compared to an actual date cell value?
PS. Q17 is actually Q16
Try CoreCompute = CDbl(Trim(oXmlHttp.ResponseText))
This probably works because your response is a string and it could have whitespace included.
Trim will remove the whitespace
CDbl will ensure that value is converted to a number type.
I have a field with values both text and numbers. But the data type of the column containing the field is set to text
Example Values in column F1 can be = 100111 , P100T5
My code is:
Dim Value as string
Sheets("Piv").PivotTables("P1").PivotFields("F1").ClearAllFilters
Sheets("Piv").PivotTables("P1").PivotFields("F1").CurrentPage = Value
The code works when Value = P100T5 but not when 100111. Basically it doesn't work when it is a number value.
Any help in this would be greatly appreciated.
I have created a DataGridView and I add columns to it like this:
Dim col_1 = New DataGridViewTextBoxColumn
col_1.Name = "Date"
col_1.DefaultCellStyle.Format = "MM/dd/yyyy"
data_grid.Columns.Add(col_1)
then I add data to the column like this:
data_grid.Item(1,1).Value = temp_date
The grid is filled with the correct data and everything works, however...when I click on the column headers, the column that shows the dates does not sort correctly (it sorts alphabetically) and I know this is because I set it up as "DataGridViewTextBoxColumn", but there is no option for a date type column. So how to I set it up as a date column so it sorts based on the date when the header is clicked?
Thanks.
You should also set the ValueType of the column:
DataGridView1.Columns(0).ValueType = GetType(Date)
Then convert date_temp to a Date-value before assigning this to the cell's Value.
Using CDate could be your first attempt:
data_grid.Item(1,1).Value = CDate(temp_date)
otherwise, investigate Parse, TryParse or Convert, to obtain the date-value.
