show multiple selections on a parameter in header

[mart10]

I am using cr 2016

I have a parameter and I can select one or more items

I also have the parameter in the header so you can display the selection. This works fine for selecting one item BUT not if I select more than one (data itself is fine its just the display in the header)

Ideally I would like it to show each selection in this format --> select a, select b, select c etc etc

What is the datatype of the parameter?

Also, what is the ultimate display? Let’s say the parameter is {?Car}. Are you saying you want to see:

Mazda, Chevrolet, GMC

?? Or what specifically?

-LB

 

[mart10]

its string parameter and yes as per your example, I drop the ?Parameter into the header and want to show as you suggest. At moment it just seems to show one value

 

[lbass]

Place this formula in the header:

stringvar x;
numbervar i;
for i := 1 to ubound({?parm}) do(
x := x + {?parm}+", "
);
left(x,len(x)-2)

-LB

public static string ConvertArrayToString(object[] values)
{
var result = new StringBuilder(values[0].ToString(),values.Length);

for (int i = 1; i < values.Length; i++ )
{
result.AppendFormat(", {0}", values);
}
return result.ToString();
}

I just normally do my parameter displays like this:
if {?Parameter}="*"
then "All Parameters"
else join ({?Parameters},",")

if you don't have the wildcard then you could just use
join ({?Parameters},",")
