DateTime Parameter

cohalloran

Hi ,

2 things if you can help pls

1) In a Datasource Query, in the Query Wizard I'm trying to create a date paramter
I tried the following props:

Name: param1
DataType: DateTime
Default Value: [Date]
Expression: [Date]
Size: 30.

No matter what value I set for 'Default value' or 'Expression' I cannot get it to work.
I'm getting this error "Failed to convert parameter value from a Variant to a Datetime".

2). I have a databand with a Table object that prints data from a datasource as part of the ManualBuild Script Event.
In the Edit Databand window I have Data Source Set to None.
If I select the datasource in the Edit Databand window the table prints multiple times as expected.
If you have a table object in your databand that prints out a data source. Is it possible to filter this data without repeating the table?

Thanks in advance

Hello,

1) You have to set DefaultValue to something like 1/1/2000 - it must be a string value containing a valid date. The DefaultValue is used in design-time to get the table schema. In run-time (when you run a report) the Expression is used instead.

2) If you need to filter the data you print in the TableObject, pass the filter expression in the datasource.Init method. Here is a modified example of the demo report "Table/Row Datasource":

      // get the data source by its name
      DataSourceBase rowData = Report.GetDataSource("Products");
      // init the data source
      rowData.Init("[Products.ProductName].StartsWith(\"C\")");
