Give the report parameter initial value from another passed parameter

[Aya]

Hi All,

I am trying to make parameter at report its initial value passed from the code as a parameter 

when I set the value field in the "report parameter editor" = Parameters.param2.Value , the initial value became empty after running the report

The type of 2 parameters is string , one has datasource and the other witch passed from code didn't have 

any suggestion for solution??

Hello Aya,

Check if param2 parameter has a default value set - How to: Add Report Parameters.

If the requirement is to implements cascading parameters you can review the approaches suggested in the following help articles:

• How to: Cascading Parameters with applied filtering on Report level
• How to: Cascading Parameters with applied filtering on data source level

If the above information does not help please share more details how the parameters are configured - attach screenshots or send us a demo project in a support ticket.

Hi Aya,


I not sure i understand what you need.
But i will give it a try.


Define your param in the designer and give them default value for test.
So now you have 2 params one is the source and the other is the result.


In the code behind you can do this.

public myReport()
{
    InitializeComponent();
    this.ReportParameters["Result"].Value = this.ReportParameters["Source"].Value;
}
public myReport(string myRealParam)
{
    InitializeComponent();
    this.ReportParameters["Source"].Value = myRealParam;
    this.ReportParameters["Result"].Value = this.ReportParameters["Source"].Value;
}

Or you can use the Designer To say report parameter > result > value > = = Parameters.Source.Value


Its really hard to provide the correct solution with little information.
If this doesn't help ( i hope it will ), i will have so many question.

Aya,

I have try what you describe in your 1rst post and i can't reproduce your issue in editor preview mode.
I created 2 parameter string
The 1rst one has as default value " test" , the other has "=Parameters.P1.Value"
And everything works fine.  they both diplay test.

Do you have this issue when you call your report in your application ?

Perhaps use a specific constructor like in my previous post.

But why do you need 2 parameters with the same value? .. this really bug me.
