I'm working on Birt report.
I want to get data from specific cell in the data set.
How can I set the row and column index in binding?
If you are trying to do any data binding in BIRT don't use a dynamic text item, use a data item. Gives you the same JavaScript/Display options but increases the options for using the results.
I have created a query to calculate the sum of all of the profit values in a table, I tried to output this to a textbox on the main form of my database and I just the error #NAME?.
Has anyone tried this before and are there any major things I am missing?
We would need to see some code/design details to understand why your text box gets that #Name error.
Without those details, I'll just suggest you consider a DSum() expression, instead of a query, to load the text box. And DSum() is kind of like a SELECT query, but returns only a single value instead of a result set.
DSum("YourNumericField", "YourTable")
Examine the DSum online help topic for more details. You might find the optional Criteria parameter useful (like a WHERE clause in a SELECT statement) if you ever want to sum only a subset of rows from your table.
DSum("YourNumericField", "YourTable", "account_status = 'ACTIVE'")
If you have create query to calculate the sum called "querySum". On the form property sheet, make sure selection type you change to FORM, go to Data and select "querySum" as record source.
And then, click text box, go to the property sheet and choice Data > Control Source. So you can choice column from query to the text box.
Otherwise, if you want to use VBA. You can do like this
DSum("NumericField", "YourTable")
Or with condition
DSum("NumericField", "YourTable", "type = 'Payment'")
How do I dynamically display the 'Edit' on the hyperlink field based on the values on the rows, generated from the database.
N/B.: the gridview automatically generates rows.
Do you mean you want a DataGridViewLinkColumn in the grid with Edit displayed if appropriate? Like this:
In which case, make the whole column a LinkColumn and whether or not it's clickable will be taken care of internally by the grid. Columns which don't display Edit will not be clickable.
If you don't mean this then please provide more detail.
Is there a way to display the results from a DataSet without a table control. If I try to use something like a label, and I use an expression for the label's value, I only see the first result.
Use a List. This will repeat through your data and allows for flexibility with your textboxes.
I have a report in Reporting Services 2005, and I want to hide or show a single table column based upon a report parameter. Does anyone have any idea how to do that?
Thanks!
Use the visibility property of the column. This worked for me.
=iif(Parameters!ParameterName.Value = "TextValueOfTheParameter",False,True)
Set the Visibility for the column to an expression which will return true or false. This property can be found on in the Visibility tab on a TextBox for example.
Click the radio option for Expression and then your expression might look like
=Parameters!ShowColumn.Value
Tip: If the expression returns "False" then the column or row will be visible. If the expression returns "True", the expression will be hidden. This tricked me at first.
Let’s say my report(SSRS 2005) have 5 columns. And I want to show/ hide columns based on a parameter(multi select with all 5 column names) selected by user. do as following
1)Create a parameter of type string (ColumnVisibility is name of my parameter) with desired column names in labels for the 5 columns and INT number(01,02,03,04,05) respectively in the values in “Available Values” section of the parameter wizard.
2) Then Go to column Properties on design . Go to “visibility” and paste following
=iif(instr(Join(Parameters!ColumnVisibility.Value,","),"01")>0,false,true)
3) repeat same for all the columns, by increasing the int value by 1..see following for example
2nd column
=iif(instr(Join(Parameters!ColumnVisibility.Value,","),"**02**")>0,false,true)
3rd column
=iif(instr(Join(Parameters!ColumnVisibility.Value,","),"**03**")>0,false,true)
And so on. For SSRS 2008, when you right click on the column you can see "Column Visibility" option. paste the code in "show or hide based on an expression" section for each column.
For some of my reports I've set the Visibility (Specifically the Hidden property) for the column to:
=IsNothing(Fields!Site.Value)
Note that this only works if the relevant field can be null in the underlying dataset, otherwise you will see the blank column.
If you want to hide whole column, when there are no data at all for that specific column in the report, you can use following code in the column visibility/expression:
=IIF(IsNothing (Sum(Fields!columnA.Value, "ReportA")),False,True)
when I do as above, I can make the column disappear but it leaves a gap in my table. Is this the expected result. I was hoping the columns would also shift over. I'm trying to hind a column for one group and then display it for the next group.
To make a null column disappear,
Right-Click column to select Column Visibility, then Set expression for Hidden:
IIF(IsNothing(Fields!FieldName.Value),True,False)
