Filtering with List

[Jokerwolf]

Hello,

Here is my question.

We have the GridView, and some columns are bound to the List<MyType>.We've made a custom filter like shown in some of your. demos. Now we need to filter those columns, but the DataMemberBinding is set to the List. Some code:

01.<DataTemplate x:Key="cellTemplate">
02. <DataTemplate.Resources>
03.  <my:PercentsConverter  x:Key="PerConv">
04. </DataTemplate.Resources>
05. <TextBlock>
06.  <TextBlock.Text>
07.   <MultiBinding Converter ="{StaticResource PerConv}"
08.                 ConverterParameter="MyParam">
09.    <Binding Path="ListValues"/>
10.    <Binding Path="SomeValues"/>
11.   </MultiBinding>
12.  </TextBlock.Text>
13. </TextBlock>
14.</DataTemplate>

01.var tCol = new GridViewDataColumn()
02.{
03.     Header = temp.ToString(),
04.     CellTemplate = datatemplate,
05.     CellStyleSelector = new CellStyleSelector(),
06.     DataMemberBinding = new Binding("ListValues"),
07.     IsFilterable = true,
08.     FilteringControl = new Filtering()
09.     {
10.         Minimum = 0,
11.         Maximum = 100
12.     },
13.};

When we start the program there is no filter at these columns at all.

Hello Jokerwolf,

Probably there is something wrong with the custom filtering control. What happens if you do not set the FilteringControl property of the data column? Does the default built-in filtering work in this case?

Since we can only guess what is going on - I suggest that you open a separate support ticket and attach a sample project there so we can debug your code.

Kind regards,
