Hi,

We would like to display a filter button next to the down arrow, which is for filtering data, and would like to change the style when mouseover/mouseout. Is there a way to do it?

Thanks!

Hi Olivia,

This can be done. However, this should require an extensive amount of XAML.  By default there is a filter icon that you will click on when the mouse hovers about the ColumnManagerCell. Will your Filter button do the same thing? In any case, you will need to open up the template for the ColumnManagerCell. You can find the default templates and styles installed on your machine:

C:\Program Files (x86)\Xceed\Xceed DataGrid for WPF Professional Edition v4.3\Themes\Aero

You can open up the TableflowView if you are using this view.

Do a search (Ctrl + F) for "TEMPLATE: ColumnManagerCell". From here, you have the template for the ColumnManagerCell. I would recommend copy/pasting the xaml in a resource dictionary file in your application. Then you can play around with the XAML and change the template to your liking.

Hi Marc,

I made most of the part working based on your suggestion. One of the problems though is the background of the filter button is white, although in the xmal, it is set to transparent (and it is the one from the original source). Here is the xaml code I have. The image I added is based on the DataTemplate of  "autoFilterGlyph" with the Path.Fill section removed.

    <Style TargetType="{x:Type XceedDataGrid:ColumnManagerCell}">
        <Setter Property="ToolTip"
                Value="{Binding Path=ParentColumn.Title, RelativeSource={RelativeSource Self}}" />
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="XceedDataGrid:ColumnManagerCell">

                ... <code from TableflowView.Aero.normalcolor.xaml except for the images>

                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

Thanks!

I have tried to just copy the template without changing anything and the problem still exists. Any suggestions?
