I am trying to hide or show data on an SSRS report when a checkbox on a .NET application is checked. I am using c#.

My code is below:
 if (chkShowServiceSupportRep.Checked == true)
            {
                if (gtri_maintenanceid != Guid.Empty)
                {
                    servicesupportrep.Value = true; // causes error
                }
                else
                {
                    if (gtri_maintenanceid == Guid.Empty)
                    {
                        servicesupportrep.Value = false; // causers error
                    }
                }
            }

Open in new window


gtri_maintenanceid = Guid
servicesupportrep = Lookup

Please help

Is the above correct:  servicesupportrep is of type Lookup? Is it nullable?

Correct.....
private Lookup servicesupportrep = new Lookup();

Is Lookup a class you created? What is the type of the object returned by the Value property?

The value retruned is the Guid of a person found via a Lookup

OK, so look at what you just said:

The value retruned is the Guid...

, and look at what you are trying to do in code:

servicesupportrep.Value = true;

How can you assign a boolean (e.g. true) to something that is of type Guid?

Thats what I am trying to figure out. I have a checkbox. If the checkbox is checked then I want the value of the Lookup (Guid) to be shpwn on a Report. So, the checkbox either hides or shows the lookup value.

I also tried this:
if (chkShowServiceSupportRep.Checked == true)
            {
                if (gtri_maintenanceid != null)
                {
                    servicesupportrep.Value = gtri_maintenanceid;
                }
                else
                {
                    if (gtri_maintenanceid == null)
                    {
                        servicesupportrep.Value = Guid.Empty;
                    }
                }
            }

IIRC, there should be a Visibility property on the control you are using to display the Lookup. You can set that expression to be the value of the chkShowServiceSupportRep check box's checked state. Have you tried putting anything in the Visibility field?

What kind of control are you using for the chkShowServiceSupportRep field?
