Parameter from array with needdatasource event

[MGrassman]

I have a report that I'm creating that I want the parameter to be from an array which I know how to do but when I try to set the

.AvailableValues.ValueMember the value isn't found because I'm using the needdatasource event to bind my business object to the datasouce.

Is there anyway this value doesn't need to be set?  I'm filtering myself in the needdatasource event and am not sure how to get this to work.

------------- Here is the code in the constructor.

InitializeComponent();
string[] groupTypes = new string[5] { "All", "Connect k & OnePlan", "NON WSA", "WSA", "Administrators" };

 

 

this.ReportParameters["UserGroups"].AvailableValues.DataSource = groupTypes;

 

 

this.ReportParameters["UserGroups"].AvailableValues.ValueMember = "=Fields.UserGroups";

 

 

------------- Need Datasource looks as follows

 

Inventory.Report.Properties.

Settings settings = new Inventory.Report.Properties.Settings();

 

 

DbUtils.ActualConnectionString = settings.InventoryConnectionString;

 

 

ActivityLogCollection data = new ActivityLogCollection();

 

 

SortExpression s = new SortExpression(new SortClause(ActivityLogFields.ActivityLogId, SortOperator.Descending));

 

 

PredicateExpression f = new PredicateExpression();

 

f.Add(

ActivityLogFields.ActivityLogType == 1);

 

 

if (this.ReportParameters["UserGroups"].Value != null && this.ReportParameters["UserGroups"].Value.ToString().Length > 0 && !this.ReportParameters["UserGroups"].Value.ToString().Equals("All"))

 

{

f.AddWithAnd(

new FieldLikePredicate(ActivityLogFields.UserGroups, null, "%" + this.ReportParameters["UserGroups"].Value + "%"));

 

}

data.GetMulti(f, -1, s);

(sender

as Telerik.Reporting.Processing.Report).DataSource = data;

 

 

Seems like I should just be able to specify a parameter even if the report doesn't have a fields associated to it?

Thanks,

Hello MGrassman,

If you're using an array, the ValueMember and DisplayMember would match, so the correct syntax is:

string[] groupTypes = new string[5] { "All", "Connect k & OnePlan", "NON WSA", "WSA", "Administrators" };
this.ReportParameters["UserGroups"].AvailableValues.DataSource = groupTypes;
this.ReportParameters["UserGroups"].AvailableValues.ValueMember = "=Fields.Item";
