Creating custom column filter for boolean value column

[Martin]

I have a column in my GridView that consist of boolean values. These values are used to show an icon in the column. Now I want to be able to filter the column so that I can select rows that contain an icon, or rows that does not. 

Currently my filter does not contain any values to filter from. First I want to be able to filter the column. Second I want to customize the names for the checkboxes. So instead of just saying "True" and "False", I would like them to say "My custom string representing the true value" and "My custom string representing the false value".

Is this possible, and how would one go about creating this?

Hi Martin,

What I could suggest is to create an additional property that returns a string representation of your bool property. The following code snippet demonstrate this.

private bool reminderPassed;
public bool ReminderPassed
{
    get { return reminderPassed; }
    set { reminderPassed = value; this.OnPropertyChanged("ReminderPassed"); }
}

public string ReminderPassed_String
{
    get
    {
// or you can create custom logic here that returns different string 
        return ReminderPassed.ToString();
    }
}

<telerik:GridViewDataColumn
    DataMemberBinding="{Binding ReminderPassed_String}"
    x:Name="ReminderIcon"
    CellStyle="{StaticResource IncidentListTextEffects}"
    Header=""
    IsReadOnly="True"
    IsVisible="{Binding IsTemplateList, Converter={StaticResource InvertBoolConverter}}"
    SortMemberPath="RemindAtLocal" />

I hope this approach will work for you.
