Radgridview Filter not working

[cha]

I have a GridViewDataColumn declared as below in XAML. 

                   <telerik:GridViewDataColumn DataMemberBinding="{Binding L3Size, StringFormat='0'}"  UniqueName="L3Size"<br>IsReadOnly="True" <br>SortMemberPath="L3Size" Width="60" CellStyleSelector="{StaticResource L3SizeStyler}" ><br>                        <telerik:GridViewDataColumn.Header><br>                            <TextBlock Text="L3 Sz" TextWrapping="Wrap" Style="{StaticResource TextBlockWhite}" /><br>                        </telerik:GridViewDataColumn.Header><br>                    </telerik:GridViewDataColumn><br>

 

A filter is applied on the grid for L3Size > 0 and it works fine.  L3Size for one of the rows becomes 0 and the value is correctly displayed as 0 on the grid. 

L3Size is set to 0 in the viewmodel. But that row doesnt get filtered out.

Any idea why its happening ?

Hi,

In order the filtering to be reapplied in this scenario, a property change notification from the underlying data item needs to be raised. Otherwise, the control cannot be aware that its value has changed. This can be achieved by using the approach demonstrated in the Edit an item outside RadGridView topic.

I hope this helps.

I have a radgrid with column containing Border and Text in its

<DataTemplate>

The filtering funnel icon is missing from the grid for that column, it should be filterable like rest of the columns.

What should I do to enable filtering for such column?

I am attaching the project from google drive which will resemble my scenario. [ Attachment ]. The grid has a "Status" column which is missing funnel icon. It should filterable by text and when filtered, show text and border. Please have a look.

Solved by setting "FilterMemberPath" for the column.

<telerik:GridViewColumn FilterMemberPath="STATUS_STRING"
                                             IsFilterable="True"
                                             Header="Status" Width="1*">                             <telerik:GridViewColumn.CellTemplate>
        <DataTemplate>
             <Grid>
                <Border HorizontalAlignment="Left" VerticalAlignment="Center"
                                               Style="{Binding WARNING_STATUS,
                       Converter={StaticResource navStatusToColorCodeConverter}}">
                </Border>
                <TextBlock Margin="20 0 0 0" Text="{Binding STATUS_STRING}"></TextBlock>
           </Grid>
        </DataTemplate>
 </telerik:GridViewColumn.CellTemplate>
</telerik:GridViewColumn>

Hello, I'm using popup default filtering for my gridview and define all my columns dynamically in code.

But when I try to filter for a string or a numeric value, all my rows are removed from the collection.

How could I resolve this issue?

Hello Yefan,

I posted a reply in the other forum thread that you have opened: No rows displayed when filtering, grouping or sorting. May I ask you to continue the discussion there in order to avoid duplicating replies? 

Thank you in advance for your understanding.
