IColumnFilterDescriptor.FieldFilter.LogicalOperator working incorrect!!!

[Trần]

Hello,
From tutorial http://docs.telerik.com/devtools/silverlight/controls/radgridview/filtering/programmatic.html
I have a small code sample which demonstrates above link.​ When I ​set IColumnFilterDescriptor.FieldFilter.LogicalOperator = Or. The data load correct. But after If i click AcctNo filter column then the ​combobox "LogicalOperator" is not update​(still load "And" default.....).

Here is the MainPage xaml:

<UserControl x:Class="SaveAndLoadFilterRadGridView.MainPage"

             xmlns:telerikPager="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.Data">

    <Grid x:Name="LayoutRoot" Background="White">
        <telerik:RadGridView AutoGenerateColumns="False" ItemsSource="{Binding PendingCalls}" Name="dataGrid"
                                         SelectionMode = "Single" IsReadOnly ="True"
                                         Margin="10,0,10,0" MinHeight="200"
                                         Filtered="dataGrid_Filtered">
            <telerik:RadGridView.Columns>
                <telerik:GridViewDataColumn DataMemberBinding="{Binding InstitutionName, Mode=TwoWay}" Header="InstitutionName" IsReadOnly="True" Width="Auto" />
                <telerik:GridViewDataColumn DataMemberBinding="{Binding AcctNo, Mode=TwoWay}" Header="AcctNo" IsReadOnly="True" Width="Auto" />
                <telerik:GridViewDataColumn DataMemberBinding="{Binding FullName, Mode=TwoWay}"  Header="FullName" IsReadOnly="True" Width="Auto" />
            </telerik:RadGridView.Columns>
        </telerik:RadGridView>
        <telerikPager:RadDataPager Margin="10,0,10,0" Grid.Row="1"  Source="{Binding  Items,  ElementName=dataGrid}"  PageSize="{Binding  CRMPageSize}" />

        public string InstitutionName { get; set; }
        public string AcctNo { get; set; }
        public string FullName { get; set; }
    }
}

 

I am using Telerik controls 2012.1.424.1040 in a Silverlight 4 project.

Please review code or see attach image.

Here are the steps to reproduce:

1/ Load filter data from database (LogicalOperator = Or)

2/ The data loaded correct

3/ Select filter from column AcctNo

4/ LogicalOperator combobox display value "And" - This is incorrect!!

 

Many thanks,

VietTQ

Hello Trần,

I have managed to reproduce the issue with the version 2012.1.424.1040. However, when i tried with our latest binaries everything worked as expected. The issue is fixed. If you download the latest binaries, the project should be working correctly.

I hope this helps.

Hello Martin

I downloaded and installed TelerikUIForSilverlightSetup_2015_2_728.exe from telerik site.

When I reference library from "C:\Program Files (x86)\Telerik\UI for Silverlight Q3 2015\Binaries\Silverlight" to my project(existed Telerik controls 2012.1.424.1040), I get error. The project cannot get reference. Please see attach image.

 Note: I referenced new dll: Telerik.Windows.Controls.GridView.dll, Telerik.Windows.Controls.dll, Telerik.Windows.Controls.Chart.dll, Telerik.Windows.Controls.Charting.dll, Telerik.Windows.Controls.Data.dll, Telerik.Windows.Controls.DataServices.dll, Telerik.Windows.Controls.DataVisualization.dll, Telerik.Windows.Controls.Input.dll, Telerik.Windows.Controls.Navigation.dll, Telerik.Windows.Data.dll

 

Can you send me guide for this apply.

 

Many thanks

Hi Trần,

Please take a look at Upgrading Telerik UI Trial to Telerik UI Developer License or Newer Version article in which we describe how to upgrade your controls to a newer version. But bear in mind that we have stopped maintenance of Silverlight 4.0 and if you want to use our latest binaries, your project should be Silverlight 5.0.

I hope this helps.
