View 4 RepliesPerhaps someone has done something like this before. I am generating a quantity summary report. The quantities have to be summarized in two ways:A quantity for a specified date range, which can fall anywhere within the project duration defined by the user provided UserStartDate and UserEndDate A Quantity to date, defined by the ProjectStartDate till the user defined UserEndDate So if I put all these dates in sequence it would look something like this: ProjectStartDate, UserStartDate, UserEndDate, ProjectEndDate Right now in the code the User specified dates are vStartDate and vEndDate. The source data (list of bid items) is compiled in a UNION query (SqlServer View) and I am querying from this view using a stored procedure from which the data is captured using the code below.
Public Shared Function GETeFieldQuantityData( _
ByVal vProjectNo As String, _
ByVal vStartDate As DateTime, _
ByVal vEndDate As DateTime) _
As IEnumerable
' Dim SqlConnection, SqlCommand, and SqlDataReader
Dim vSqlConn As SqlConnection = New SqlConnection(GetConnString)
Dim vSqlCmd As SqlCommand = New SqlCommand("eFieldReturnQuantitySummary", vSqlConn)
'Dim vDataRdr As SqlDataReader
vSqlConn.Open()
'Construct parameters
vSqlCmd.Parameters.AddWithValue("@StartDate", vStartDate)
vSqlCmd.Parameters.AddWithValue("@EndDate", vEndDate)
vSqlCmd.Parameters.AddWithValue("@ProjectNum", vProjectNo)
vSqlCmd.CommandType = CommandType.StoredProcedure
'Return SqlDataReader Object
Return vSqlCmd.ExecuteReader(CommandBehavior.CloseConnection)
End Function
And the SELECT statement returning data to the form:
Code:
SELECT BidItemDesc As [Bid Item Description], Unit,
SUM(Qty) AS [Tot Qty], COUNT(*) AS Records
FROM dbo.qryQuantityWorkSheet
WHERE ((ProjectNum = @ProjectNum)
AND (ProjDate >= @StartDate)
AND (ProjDate <= @EndDate) )
GROUP BY ProjectNum, BidItemDesc, Unit
ORDER BY BidItemDesc
I remember seeing an example explaining how you could setup the asp.net chart control to show two sets of data from different date ranges on the same chart, but I can't find it now that i need it.It showed sales for Jan, Feb Mar 2009 in one series and sales for Jan, Feb, Mar 2008 in another series and had the chart in 3D so that one series was in front of another.Does anyone know of such an example or have any pointers how to achieve it?
View 1 Repliesi am working on an availability / booking system, one element in the form will be a dropdownlist control with a selection of date ranges for a customer to select the period they want to book.these will be a list of ranges for each week (monday - sunday)eg
27th Sep - 3rd Oct 2010
4th Oct - 10th Oct 2010
11th Oct - 17th Oct 2010
etc
is there an way to populate this dropdownlist dynamically from a calendar or date function so it can cater for dates up to 18 months ahead?i dont really want to populate it from database entries or hard coded list items if there is a less laborious way.
I have a formview. Inside, there is a textbox where user can input a date(txtAccepDt). Then the user will choose one item from a radiobutton list which has values like 60 days, 90 days and 150 days. If the user select the 60 days I need to add that to the Accept date and show it in a abel(lblShowFrstOp). Same will apply with other two day
View 4 Repliesin my asp.net_vb code web. there are 9 textboxes whcih is used for entering numerical/dates
first is lve.text in whicj numder is entered
second one is lvefrom.text
thirdone is lveto.text
when user fills (lve.text) 5 and enter 15 Jan 2013 in lvefrom.text then lveto.text should show 19 Jan 2013. i had posted this earlier and got reply which is mentioned below. this code below gives me 20 Jan 2013 instead of 19 Jan 2013.
tw text boxes lve.text (number filled) and lve from.text (date filled). when user enter a numder in lve.text and select a date fro date picker in lvefrom.text then lveto.text should show date selected in lvefrom.text + number of days in lveto.text (eg if number of days is 5 and date selected in lvefrom.text is 15 Jan 2013 then lveto.text should display 19 jan 2013. because the starting day is also counted in my case.
Protected Sub lvefrom_TextChanged1(ByVal sender As Object, ByVal e As System.EventArgs) Handles lvefrom.TextChanged
Dim ObjLocDate As New Date
Dim IntLocDays As Integer
IntLocDays = Convert.ToInt32(lve.Text)
ObjLocDate = lvefrom.Text
ObjLocDate = ObjLocDate.AddDays(IntLocDays)
lveto.Text = ObjLocDate.Date.ToString("dd-MMM-yyyy")
End Sub
fourt tex box is pfx.text, fifth is pfx1.text, sixth is pfx2.text
when use filles pfx.text 3 then pfx1.text should display 12 Jan 2013 and pfx2.text should display 14 Jan 2013. these are the prefix for leave( as 12 to 14 Jan 2013 is prefix.seveth is sfx.text, eighth is sfx1.text and nineth is sfx2.text
when user fills sfx.text 3 then sfx1.text should display 20 Jan 2013 and sfx2.text should display.
