Hi,
I am writting the control Template of HeaderPrefixArea as below:
<Style TargetType="{x:Type igDP:HeaderPrefixArea}"><Setter Property="Visibility" Value="Visible"/> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type igDP:HeaderPrefixArea}">
<Grid> <ContentPresenter Content="{TemplateBinding Content}" ContentTemplate="{TemplateBinding ContentTemplate}" VerticalAlignment="{TemplateBinding Control.VerticalContentAlignment}" HorizontalAlignment="{TemplateBinding Control.HorizontalContentAlignment}" /></Grid>
</ControlTemplate></Setter.Value></Setter></Style>
Now if I set HeaderPrefixAreaDisplayMode="FieldChooserButton", it is not appeared at all in the prefix area.
<eclp:EclpGrid.FieldLayoutSettings><igDP:FieldLayoutSettings SelectionTypeRecord="Single" AutoGenerateFields="False" HighlightAlternateRecords="True" HeaderPrefixAreaDisplayMode="FieldChooserButton" ></igDP:FieldLayoutSettings></eclp:EclpGrid.FieldLayoutSettings><eclp:EclpGrid.FieldLayouts>
If I comment the Style, it works. Kindly suggest.
Hello,
When you are retemplating an element, we recommend that you get the default style and create your own based on it to keep all the functionality. The default style for this HeaderPrefixArea you can find in the DefaultStyles directory in the Infragistics folder.
Thanks for your response but I couldn't find any style for HeaderPrefixArea.
It would be great if you could provide some example to get default behavior.
The style you can find in the DataPresenterGeneric_Express file. Here is the default style anyway:
<Style TargetType="{x:Type igDP:HeaderPrefixArea}">
<Setter Property="HorizontalAlignment" Value="Center"/>
<Setter Property="VerticalAlignment" Value="Center"/>
<!--<Setter Property="Visibility" Value="Hidden"/>-->
<Setter Property="Visibility" Value="Visible"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type igDP:HeaderPrefixArea}">
<StackPanel Orientation="Horizontal" HorizontalAlignment="{TemplateBinding HorizontalAlignment}" VerticalAlignment="{TemplateBinding VerticalAlignment}">
<!--Button that displays field chooser-->
<Button
x:Name="fieldChooserButton"
Style="{DynamicResource {x:Static igDP:DataPresenterBase.FieldChooserButtonStyleKey}}"
Command="{x:Static igDP:DataPresenterCommands.ShowFieldChooser}"
CommandParameter="{TemplateBinding FieldLayout}"
Visibility="Collapsed"/>
<ContentPresenter
Content="{TemplateBinding Content}"
ContentTemplate="{TemplateBinding ContentTemplate}"
VerticalAlignment="{TemplateBinding VerticalContentAlignment}"
HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}"/>
</StackPanel>
<ControlTemplate.Triggers>
<DataTrigger Binding="{Binding RelativeSource={x:Static RelativeSource.Self}, Path=FieldLayout.HeaderPrefixAreaDisplayModeResolved}" Value="FieldChooserButton">
<Setter TargetName="fieldChooserButton" Property="Visibility" Value="Visible" />
</DataTrigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Thanks for your support.
It works.

Hi, Ritesh:
Could you please share the template with me? I tried to put both a checkbox and the field chooser inside HeaderPrefixArea but I can not let both of them displayed. The width of the header is too narrow.
Any help is highly appreciate.

I proceeded as per the suggestion from Alex & default style could be found in DataPresenterGeneric_Express.xaml file.
Hi, Alex:
It works. Thanks a lot.
Have you tried setting the RecordSelectorExtent property of the FieldLayoutSettings?
xamDataGrid1.FieldLayoutSettings.RecordSelectorExtent = 300d;
Thanks a lot for the reply. I am using the default style but I could not change the width of "HeaderPrefixArea". Now I have two icons squeezed into a small area which makes it pretty hard to see them.
Alex, any suggestions for the problem? Basically I need to widen HeaderPrefixArea using styles.
