Creating reports and dashboards | Stimulsoft community forum

Hi Stimulsoft,
I am attempting to render several fields within label using a variable. I'm attempting this because the variable name will always be the same, versus the label name having a potentially different name.

For example, if I have a datasource "Transactions" with 6 fields:
- Date
- Item
- Item Description
- Cost
- PersonID
- PersonName

I am able to render any number of fields in the group header label using {Transactions.Item} - {Transactions.Description}.
But, If I create a variable of type string using a value type of Expression named "GroupLabel" and set the expression to "Transactions.Item", nothing is shown. If I set the Expression to "Transactions.Item + "B"", only the "B" character is shown.

Is it possible to render data fields within variables?
If so, how?

Thanks.

Hello,

Can you please send us your report with test data which reproduce the issue for analysis.

Thank you.

I am very sorry for the delay in responding.
I have attached an example that illustrates the issue I am having.
There are two columns: Products.UnitPrice and Products.UnitsInStock

If I create a simple text expression with a value of: I get the expected result (ex. 2 * 3 = 6)

If I create a variable ("TotalValue" in the sample), and attempt to do the same thing: I always get 0.

Am I doing something wrong?

Thanks!

Hello.

Please, try to set Read Only option of the variable.
Then the expression will be calculated on each request.
You could read more information about this option on the User Manual.

Thank you.

Thank you for the clarification Aleksey. Works like a champ!
