Report Builder Textfield multiple values

[DerMainzer]

Hey,

I'm sure this is an easy one for you, but it's my first day with report builder:

I defined a parameter vor Names as e Text Value. I defined: Leave empty "" and the values come from a simple table with Names as you can see in the drop down.

The problems are:

1. Whatever I choose in the drop down the Report says #Error

2. If Í don't choose anything the Report Builder forces me to choose

I have no idea what to do

This is because when you turn on the multiple values option the parameter returns an array instead of a single scalar value.

So instead of just referencing the parameter directly 

eg.

=Parameters!ReportParameter1.Value

You need to right click on the text box which is showing #Error then edit the expression to wrap the parameter reference in the Join() function. 

eg.

=Join(Parameters!ReportParameter1.Value,",")

If you want to allow people to run the report without selecting a value you need to configure a default value and you will also need to add this default value to your allowed values.

Hi,

thanks for your help - the Join did work.

Unfortunately the default value I typed in doesn't show up, I think it's because it's not a value from the list the parameter is pointing at, right?. I also don't understand why there is a check box for "accept empty value" if it doesn't work....

Thanks again,

Tim

Yes, unfortunately once you specify an allowed list then only values from that list are accepted. If you don't have an allowed list the user can type any text they like, but then you loose the multiple items option.

It's conflicting with the Allowed Values property. If you also had an empty string as an allowed value it would work.
