Here's my problem. I am passing in a parameter let say it's called ShapesSelected.
ShapeSelected = ",Square, Triangle, Circle,".
The problem is ShapeSelected could be any of the the shapes so it is never static.
Base on this parameter I want to add 3 column to the right of a table in the report. Is this possible? I've starting coding it in Custom Code in Report Properties but I am stuck as in how to add the column.
Public Function GetReportShapes( ByVal ShapesSelected As String )
Dim Shapes() As String
Dim result As String
Dim i As Integer
Entities = Split(ShapesSelected ,", ")
For i = 0 To UBound ( Shapes)
Select case Shapes(i)
case "Square": 'add Square Column here
case "Rectangle": add Rectange Column here
case "Triangle": add Triangle Column here
End Select
Next i
End Function
Thus rendering the columns like this:
Square Triangle Circle
Add all the columns you need and use the hidden or visible property (I forget which) with vb expressions to turn them on and off.

I have a columns with numbers that determine a job and suffix:
Example:
|Jobnumber|Suffix|
x001 1 - white
x001 2 - grey
x001 2 - grey
x001 3 - white
x002 1 <---- where it would break the alternating color, Should be grey!
x002 1 - should be grey
x002 1 - should be grey
x002 2 - should be white
x002 2 - should be white
x003 1 - should be grey
I have the report set up to accept a range of Jobnumbers and a range of Suffixes so each Jobnumber has a set of suffixes ordered by ascending. I have the expression code alternate by the different Suffix numbers by color but it breaks when the next Jobnumber and Suffix is up next in the report.
How can I get the rows to still alternate by color when the next set of Jobnumbers and Suffixes come up in the report?
If you want your alternating row colours to ignore the jobnumber and suffix then base your expression on ROWNUMBER instead Suffix.
e.g. =IIF(ROWNUMBER(Nothing) MOD 2, "LightBlue", Nothing)
UPDATE: BASED ON REVISED QUESTION
There may be a more elegant way of doing this but the following should work.
The first thing to do is go to the report properties and add two report variables to your report. Add AltBackColour with a value of 1 and LastRownumber with a value of -1. Switch off the read-only check box
Next, click on the Code tab add the following function.
Public Function BackColour (ByVal cuRowNumber AS Integer, ByVal lastJobNumber AS String, ByVal curJobNumber AS String, ByVal lastSuffix AS Integer, ByVal curSuffix AS Integer) as Integer
' Check if EITHER the job or suffix have changed, if so, switch the backcolour flag and update the report variable.
Dim switch as boolean
switch = ((lastJobNumber <> curJobNumber) or (lastSuffix <> curSuffix)) and cuRowNumber <> Report.Variables!LastRowNumber.Value
If Switch = true THEN
IF Report.Variables!AltBackColour.Value = 0 THEN
Report.Variables!AltBackColour.Value = 1
ELSE Report.Variables!AltBackColour.Value = 0
END IF
End if
Report.Variables!LastRowNumber.Value = cuRowNumber
BackColour = Report.Variables!AltBackColour.Value
End Function
Finally, set the BackgroundColor property of the row to the following expression.
=IIF(
Code.BackColour(
RowNumber(Nothing)
, Previous(Fields!JobNumber.Value)
, Fields!JobNumber.Value
, Previous(Fields!Suffix.Value)
, Fields!Suffix.Value
) = 0
, Nothing
, "LightGreen"
)
I did this with your sample data and got the following result.
Basically the code checks to see if either the job of suffix have changed and switches a flag between 1 and 0 to indicate which colour to use. It also checks that we are not checking the same row as previously. We do this because even though we set the row's backcolor property, what actually happens is each cell gets is backcolor property set meaning the code gets called for each cell and will keep flipping the flag. By checking if the row has changed we get round this.
I have 3 combo boxes that contain numbers:
Me.Authorized
Me.Officer
Me.Enlisted
What I'm trying to do is add the values of Me.Officer and Me.Enlisted and make sure it equals Me.Authorized. I have all the other statements/commands figured out, but I can't wrap my head around this one.
The combo box selected value is a string, even when that string contains only digits. You can use Val() to convert that string to a number.
So your required condition can be expressed as ...
Val(Me.Officer) + Val(Me.Enlisted) = Val(Me.Authorized)
You can enforce that requirement in the form's Before Update event ...
Private Sub Form_BeforeUpdate(Cancel As Integer)
If (Val(Me.Officer) + Val(Me.Enlisted) <> Val(Me.Authorized)) Then
MsgBox "Officer plus Enlisted must be equal to Authorized."
Cancel = True
End If
End Sub
That event procedure will abort a record save when your requirement is not satisfied.
i Placed this code in my report property code
Public Function PageNumber() as String
Dim str as String
str = Me.Report.Globals!PageNumber.ToString()
Return str
End Function
and called in my text box in body of report Like this
=Code.PageNumber()
It was not able to repeat textbox on each page.
It is showing the page number as 1 only on first page.
need to show pagenumber in each page of the output in body of the report
Kindly help me on this if u have any solution.
First Follow the steps 1 below to do pagination:
1)
1.1. Click the Details group in the Row Groups pane.
1.2. From the Tablix member Properties pane, expand “Group”-> “PageBreak”.
1.3. Set the “BreakLocation” to “End” and set the “Disable” property to the expression like below:
=IIF(rownumber(nothing) mod 40=0,false,true)
The above point 1 is use to do pagination in Report output(Display only 40 records per page in output)
2) use custom code:
Public Function PageNumberno(val as integer) as String
Dim str as String
str =(val/40)
Return str
End Function
3) Create Calculated column in Dataset and enter =0 in expression
4) In 2 Calculated Column
1)Pageno
2)No in Dataset
In Report Body use Expression for PageNo :
=code.PageNumberno(Rownumber("DataSet1"))
use Expression for No :
=IIF(Instr(code.PageNumberno(Rownumber("DataSet1"))
,".")<>0,
(Left(code.PageNumberno(Rownumber("DataSet1")),
(Instr(code.PageNumberno(Rownumber("DataSet1")),".")-1))+1)
,code.PageNumberno(Rownumber("DataSet1"))
)
5)Right click and insert column on Right Side and in Column name add code in Text box
=ReportItems!No.Value
Note: No is calculated Field column name.
6)Under AdvancedMode
IN Row Group select Static and Set RepeatOnNewPage Properties to True
In the Above Column created under point 5 will display correct page no in every page in body of the report
I have Tried and its working Fine..Try it.
I usually put a text box in the footer of the report (which will automatically display on every page) with the following line of code in it (no report property code needed):
="Page " & CStr(Globals!PageNumber) & " of " & CStr(Globals!TotalPages)
I am trying to add from two separate text boxes from different datasets I had to create a code to summarize (codes below) giving a total. What I am trying to do is get GapTotal + GapTotal2 together into a separate dataset. Unfortunately I get a blank. Can anyone help? Thank you in advance
Public GapTotal AS Integer = 0
Public Function Sum(ByVal Value As Integer) As Integer
GapTotal = GapTotal + Value
Return Value
End Function
Public GapTotal2 AS Integer = 0
Public Function SumIt(ByVal Value As Integer) As Integer
GapTotal2 = GapTotal2 + Value
Return Value
End Function
There are two possible approaches l can think of here.
First reference the values in each dataset and add the values see this posting - Stack Overflow posting
Second place the values from each data into a control eg a text box, then add the values in each text box see - SQL Server Central posting
I created a custom color palette for my charts using a technique described on TechNet.
I also have a series of drill-through column charts, where you click on one column and it passes a parameter through to the next chart and so on, giving the appearance of drill-down.
My graphs consist of 3 types of labor, and have three colors on the main chart. When I drill down to the next chart, some of the categories do not have all three types of labor that the main one has. So the first color in the palette is assigned to the series, even though it was the second color on the previous chart. I'd like to avoid this, if possible.
So a data value is green on the first chart (2nd in the color order) and yellow on the next chart (1st in the color order). How do I make the graphs "remember" the total number of series groups that were in the first chart?
This is Reporting Services 2005.
You cannot fix this using custom colour palettes.
What you can do is assign the labour type a colour in the database (using HEX is easiest). Then pass that in in your data set. Then set the color property to you hex value.
Unfortunately this is not possible. I've been looking for this for quite some time...
I was able to solve this because I was using a custom color palette, implemented as a hash table. I basically serialized this information and passed it to a hidden parameter on the subreport and then reinflated the data structure.
It's not perfect, but it works for now.
' Define some globals, including the color palette '
Private colorPalette As String() = _
{"#FFF8A3", "#A9CC8F", "#B2C8D9", "#BEA37A", "#F3AA79", "#B5B5A9", "#E6A5A4", _
"#F8D753", "#5C9746", "#3E75A7", "#7A653E", "#E1662A", "#74796F", "#C4384F", _
"#F0B400", "#1E6C0B", "#00488C", "#332600", "#D84000", "#434C43", "#B30023"}
' color palette pulled from SAP guidelines '
' http://www.sapdesignguild.org/resources/diagram_guidelines/color_palettes.html '
Private count As Integer = 0
Private colorMapping As New System.Collections.Hashtable()
' Create a custom color palette '
Public Function GetColor(ByVal groupingValue As String) As String
If colorMapping.ContainsKey(groupingValue) Then
Return colorMapping(groupingValue)
End If
Dim c As String = colorPalette(count Mod colorPalette.Length)
count = count + 1
colorMapping.Add(groupingValue, c)
Return c
End Function
' In custom actions of the data value, set the results of this '
' function to the mapping parameter in the next report '
Public Function PassColorMapping() As String
If colorMapping.Count = 0 Then
Return Nothing
End If
Try
' convert the hashtable to an array so it can be serialized '
Dim objHash As Object()() = ToJaggedArray(colorMapping)
' serialize the colorMapping variable '
Dim outStream As New System.IO.StringWriter()
Dim s As New System.Xml.Serialization.XmlSerializer(GetType(Object()()))
s.Serialize(outStream, objHash)
' move on to the next report '
Return outStream.ToString()
Catch ex As Exception
MsgBox(ex.Message)
End Try
End Function
I ran into an issue where I couldn't find the equivalent of the onLoad event for the report. Since I wasn't sure where to put this inflate code, I stuck it in the background color of the plot area. Hence I always return "WhiteSmoke". I'll change this if I can find the right place to put it.
' Call this function when the report loads to get the series groups '
' that have already been loaded into the custom color palette '
' Pass in the parameter used to store the color mapping '
Public Function InflateParamMapping(ByVal paramMapping As Parameter) As String
Try
If paramMapping.Value Is Nothing Then
Return "WhiteSmoke"
ElseIf colorMapping.Count = 0 Then
Dim pXmlized As String = paramMapping.Value
' deserialize the mapping parameter '
Dim s As New System.Xml.Serialization.XmlSerializer(GetType(Object()()))
' get the jagged array and convert to hashtable '
Dim objHash As Object()() = DirectCast(s.Deserialize(New System.IO.StringReader(pXmlized)), Object()())
' stick the result in the global colorMapping hashtable '
colorMapping = ToHashTable(objHash)
count = colorMapping.Count
End If
Catch ex As Exception
' MsgBox(ex.Message) '
End Try
Return "WhiteSmoke"
End Function
ToJaggedArray() and ToHashTable() are helper functions because a HashTable is not serializable since they implement an IDictionary. I was in a hurry so I just converted them to an array right quick. Code comes from the Collection Serialization in ASP.NET Web
Services article written by Mark Richman. I converted the code from C# to VB.NET to use in the report.
Public Function ToJaggedArray(ByVal ht As System.Collections.HashTable) As Object()()
Dim oo As Object()() = New Object(ht.Count - 1)() {}
Dim i As Integer = 0
For EAch key As Object in ht.Keys
oo(i) = New Object() {key, ht(key)}
i += 1
Next
Return oo
End Function
Public Function ToHashTable(ByVal oo As Object()()) As System.Collections.HashTable
Dim ht As New System.Collections.HashTable(oo.Length)
For Each pair As Object() In oo
Dim key As Object = pair(0)
Dim value As Object = pair(1)
ht(key) = value
Next
Return ht
End Function
Now in the report itself you need to do a couple things.
Add a reference to System.Xml in Report Properties in both reports.
In the Actions of your parent report, set the Parameter containing your data structure to =Code.PassColorMapping()
In the Plot Area section of your report, put this expression for the background: =Code.InflateParamMapping(Parameters!colorMapping)
And of course, in the Fill for your data Series Style on both charts put this expression: =Code.GetColor(Fields!Type.Value)
You can continue doing this for as many subreports as you want - I currently have 3 levels of drill-through and it works fine.
I solved that extremely easy.
In my parent report I have lets say 12 series fields, each one getting their own color in a chart, on my child report I just keep all series on the chart, for instance going from a column chart to a line chart using drill down, but I control the visibility of them...
So in the child report in Series Properties -> Visibility I just add an expression:
=(Fields!ContentType.Value <> Parameters!ContentType.Value)
This way the report only keeps the visibility of the clicked value and hides all the others and the colors remains the same :)
