_compositeFilterDesriptor.CreateFilterExpression(parameterExpression);
In example:
Filter value is: "dasdasddasdasd"
Expression is: (stringColumn1 contains dasdasddasdasd) OR (stringColumn2 contains dasdasddasdasd) OR (dateTimeColumn IsEqual 01-01-0000) OR (decimalColumn1 IsEqual 0) OR (decimalColumn2 IsEqual 0)

I am using the RadGridView and RadDataPager in a WPF application. I have a method that pulls pages of Employees from a database (or some other data source). There are more Employees than I want to put in memory at one time, so I need to page the data retrieved from the database.

So, I have a method that returns pages of data in the form of IEnumerable<Employee>. Each IEnumerable<Employee> is one page of data.  The xaml is set up this way:

    <Grid>

...

        <telerik:RadGridView ItemsSource="{Binding PagedSource, ElementName=radDataPager}"

                             Horizontal Alignment="Left"

                             AutoGenerateColumns="False"

                             x:Name="radGridView1"

                             VerticalAlignment="Top"

                             Height="Auto"

                             Width="Auto"

                             Grid.Row="0">

            <telerik:RadGridView.Columns>

                <telerik:GridViewDataColumn DataMemberBinding="{Binding FirstName}"

                                            Header="First Name"

                                            UniqueName="FirstName" />

                <telerik:GridViewDataColumn DataMemberBinding="{Binding LastName}"

                                            Header="Last Name"

                                            UniqueName="LastName" />

                <telerik:GridViewDataColumn DataMemberBinding="{Binding Age}"

                                            Header="How Old?"

                                            UniqueName="Age" />

            </telerik:RadGridView.Columns>

        </telerik:RadGridView>

        <telerik:RadDataPager x:Name="radDataPager"

                              Source="{Binding Employees2}"

                              DisplayMode="FirstLastPreviousNext"

                              IsTotalItemCountFixed="False"

                              PageSize="3"

                              Grid.Row="1"

                              Margin="0,9,0,0"

                              PageIndexChanging="radDataPager_PageIndexChanging"

                              PageIndexChanged="radDataPager_PageIndexChanged"/>

    </Grid>

I only get the first page with 3 records. Can this be fixed, or am I trying to do something that these controls do not support?

What would be a better way to do what I am trying to do?

Thanks.

Hello.

I'm try host GridView WPF in WinForms App...

When app starting Grid is clear. When I'm apply filter or sorting, data loading.

I'm try wpfGrid.Rebind(). No effect...
