[Solved] RadDatapager with dynamic PageSize, depending on the size of the window.

[LRScudeletti]

I would remove the RadGridView scrollbars, I will use the RadDataPager to display only the amount of items that fit on the screen. But is not working. Any idea how to proceed? Sorry for my bad English.

My Code:

<Grid>

    <Grid.RowDefinitions>
        <RowDefinition Height="Auto" />
        <RowDefinition x:Name="rGridView"
                       Height="*" />
    </Grid.RowDefinitions>

    <telerik:RadDataPager PageSize="{Binding LinhasGridView, ElementName= ucCadastroCidade}"
                          Grid.Row="0"
                          Source="{Binding Items, ElementName=dtCidade}"
                          IsTotalItemCountFixed="True"
                          DisplayMode="FirstLastPreviousNextNumeric, Text" />

    <telerik:RadGridView x:Name="dtCidade"
                         Grid.Row="1"
                         AutoGenerateColumns="False"
                         ItemsSource="{Binding ListaCidade, ElementName= ucCadastroCidade}">
        <telerik:RadGridView.Columns>
            <telerik:GridViewDataColumn Width="*"
                                        Header="Cidade"
                                        DataMemberBinding="{Binding nm_Cidade}" />
            <telerik:GridViewDataColumn Width="*"
                                        Header="Estado"
                                        DataMemberBinding="{Binding UF.nm_Uf}" />
        </telerik:RadGridView.Columns>
    </telerik:RadGridView >

</Grid>

Here I do the calculation:

LinhasGridView = (double)(rGridView.ActualHeight / dtCidade.RowHeight);

Thank you!

Hello LRScudeletti,

A possible way to fulfill your requirement is to bind the PageSize property of the DataPager to e a property in your ViewModel. Then to update it you can use the SizeChanged event of RadGridView. In addition, I attached a sample project that demonstrates the suggested approach.

Please note that you will need to implement the INotifyPropertyChanged interface for your ViewModel.


I hope this helps.
