Hi everyone I use Crystal Reports with Visual Studio 2010 and have the following issue that I can't seem to solve. I have a parameter called name, and I make it so a user chooses from a drop down list of employee names. It is an optional parameter so the user can select nothing in which case I would like the report to show ALL the employees except for the rows that have field Employee name empty. Now I think I got the second part of it down, because I put a formula in the detail section that seems to hide all the empty employees. The problem is that if I leave the parameter unselected the report ONLY shows rows with field Employee name empty. I created a formula like so:
if not (hasvalue(({?Zaduzioc}))) then True
else if
hasvalue({?Zaduzioc}) then
{Inventar_Model_ReportClass.ImeZaduzioca} in {?Zaduzioc} and
{Inventar_Model_ReportClass.Status} = "Aktivno"
Now this exact same formula works for me if I use it with a different report and parameter but that parameter has no empty values so I'm guessing it equates to something like if there are empty values show only those rows if not show everything.
The problem is I can't figure out how to tell it to show everything.
Any help would be greatly appreciated.
I managed to make it work, the problem was in the edit for the parameter I didn't set optional to true, overlooked it and as soon as I did that it all worked. So to recap for anyone with this problem: Make your parameter set optional to true, and put this in the formula for record selection:
if not (hasvalue(({?Parameter}))) then True
else if
hasvalue({?Parameter}) then
{table.column} in {?Parameter}
That should be that.
If you are selecting from a dropdown, you can add an item, Value = ALL, Description = ALL. Set your default to this value. Then in the Selection Expert, add this to your selection query:
....
AND
(IF {?Parameter} = 'ALL' THEN
{databasefield} = {databasefield}
ELSE
{databasefield} = {?Parameter})

I created a parameter [GroupID] that is used to query several datasets in my SSRS report. It is using the field [GroupID] from my GroupList_Rolling12 dataset. An example of [GroupID] is 77610N. When 77610N is selected, all of my datasets are correctly 'filtering' for this [GroupID].
I now need to create a text box that returns the [GroupName] of [GroupID]. In other words, when 77610N is selected from my GroupID parameter, I want the [GroupName] that is associated with the selected GroupID parameter to display.
I'm still very new to SSRS and cannot figure this out. I tried creating the expression =First(Fields!GroupName.Value, "GroupList_Rolling12") but that did not work since it simply returns the first value from the query.
I also tried =First(Parameters!GroupID.Value(0)) but this also did not work
I also tried this expression =Lookup(Fields!GroupID.Value, Fields!GroupID.Value, Fields!GroupName.Value, "GroupList_Rolling12")
)
Can you please help?
You can reference the parameter label directly like this
=Parameters!GroupID.Label
There is no need to put the index on the end (=Parameters!GroupID.Label(0)) unless your parameter is multi-value, in which case it would select the first selected entry.
unfortunately I'm not an expert of Crystal Report, so I'll post here my question hoping for any help about my issue.
I want to display inside my report the result of a filter on a SQL RecordSet; this RecordSet is looked up from an a single table, of which I want to show some fields of my SQL table, while the filter I want to apply is based on a field parameter (defined static) that I'm trying to set programmatically.
Here below I attached my code where I'm applying the record selection formula, I tried also hard-coding the value instead of passing it through a dropdown selection:
ReportDocument RPT_Doc = new ReportDocument();
RPT_Doc.Load(RPT_Path_Name, OpenReportMethod.OpenReportByDefault);
ApplyConnInfos(ref RPT_Doc);
RPT_Doc.SetParameterValue("data_riferimento", "20161001");
RPT_Doc.RecordSelectionFormula = "{viaggi.data_part_pre} = '20161001'";
crystalReportViewer1.ReportSource = RPT_Doc;
In the first image attached you can find the field parameter definition, while second image is the record selection formula I defined inside my report:
The report always shows all the records of my table (more than ten thousand rows), instead of displaying a filtered RecordSet. The odd thing is Preview function from Visual Studio works like a charm; it prompts the field value, once I confirm the value the viewer displays the report with the rows filtered as I expect..
What am I missing from report/C# program configuration to make the record selection work?
Thank you in advance for any suggestion you can give me :)

Ok, finally we got the solution to our issue.
We found the CrystalReportViewer object used to display generated reports has 2 different properties, SelectionFormula and ViewTimeSelectionFormula; both has default value set to empty string.
Below I attached the picture of .Designer.cs file with the 2 properties valued:
We commented those 2 properties and the selection formulas and field parameters applied through code / report designer worked again.
I'm struggling with Crystal Reports suppressing rows whenever I add a field that some rows may not have data in.
I've been able to fix some of the rows and make them show by using the formula:
if not isnull({field}) then {field} else "Arbitrary string to make row display"
This at least fills in the absent field with something and displays the row.
Do I really have to try and identify every field that may have incomplete data for some rows? Or is there some global method to make all rows show no matter what?
Something like: If isnull(ANYTHING) then " "?
you can do right click on the field, then under suppress, click the formula icon beside it and you can input there the conditions.
You can try the following in report options:
Convert Database NULL values to Default
Convert Other NULL values to Default.
This is hidden in File > Report Options. I have used Convert Database NULL Values to default to show 0's instead of blanks for null valued summaries
I have a formula written for a field in Crystal Reports. When i refresh the report, i get a different value from the formula. The required value is always the last value in Browse Field Data dialog for that formula.
Isnt the formula supposed to have only one value as output? why are multiple values shown in browse field data dialog.? Is there a way to retrieve last value of Browse File Data dialog?
My formula looks like below:
WHILEREADINGRECORDS;
NumberVar CODTOTAL;
if {XXX.YYY} = 1 then
( CODTOTAL := CODTOTAL + {XXX.ZZZ};
);
CODTOTAL;
Browse field data shows all the values "CODTOTAL" acquires as a result of that formula and displays a random value amongst the assigned value.
Please help me out. I am amateur in crystal reports.
Any help would be highly appreciated.
~Regards.
First observation should be where have you placed the formula (Details, Footer.. etc).
why are multiple values shown in browse field data dialog.?
Browse field shows the data that is present in the table but in your case you are applying "If" condition of the filed. It can be possible that there is only one record that satisfies your condition.
I would suggest to run the report without the codition, Check the results and apply the condition and check results again.
I am creating a report in SSRS 2005 and where there should be a NULL value in the table it is returning a value ("Alle" [the tables are mostly in German]). This isn't really a problem as I think I can hide the value as explained here:
How to hide certain on SQL Reporting Services 2005
However, when I add =Replace(Fields!LengthofFunding.Value,"Alle","") to the Expression box in the field I want to hide the value for it is returning a FALSE value rather than a blank.
Can anyone let me know how I can make this field return a blank value?
I think instead of replace you can use the Iif as following:
=Iif(Fields!LengthofFunding.Value = "Alle", " " , Fields!LengthofFunding.Value )
This means if its equal to "Alle" replace with blank, else keep the original value.
