Creating the Filter Descripter for From and To date

08-31-2009 8:28 AM |

Hi All,

I have just created a sample application in silverlight using RIA Services,

Now I want to create a new filter descriptor which will take From date and To date from DatePicker and all the data will be loaded between this date.

I was able to create a filter descriptor using a date difference, like data for last month.

Thanks in advanced,

Thanks & Regards,
Dhiraj Ranka

Hi Dhiraj.ranka,

It shall similar with the below.

           <riaControls:DomainDataSource x:Name="source" QueryName="GetEmployeesByGender" AutoLoad="True">
                <riaControls:DomainDataSource.DomainContext>
                    <domain:AdventureWorksDomainContext />
                </riaControls:DomainDataSource.DomainContext>
                <riaControls:DomainDataSource.QueryParameters>
                    <riaData:ControlParameter ParameterName="startDate" ControlName="myStartDatePicker" PropertyName="SelectedDate" RefreshEventName="SelectedDateChanged" />
                    <riaData:ControlParameter ParameterName="endDate" ControlName="myEndDatePicker" PropertyName="SelectedDate" RefreshEventName="SelectedDateChanged" />
                </riaControls:DomainDataSource.QueryParameters>
            </riaControls:DomainDataSource>

Best regards,

Jonathan

Thanks Jonathan,

I understood this point but now the point is that I have already added a FilterDecriptor on Domain Data Source, so can I use control parameter and filter descriptor together?

If yes then how the IEnumerable method will look like with ControlParameter (for example, GetEmployeesByGender() which is used as QueryName).

Is it parameter name is the name of the database field or something else?

See I know its confusing but I have asked what ever came to my mind

I hope you understand this ;-)

Thanks & Regards,
