How To Apply Conditional Formatting To A GridViewColumn.FooterCellStyle?

[Albert]

Hi,

I would like to add conditional formatting to cells in the summary footer row (I want the display values from GridViewColumn.AggregateFunctions to have different background colors based on if they are negative or positive, plus other conditions).

I see that there is a property for GridViewColumn.GroupFooterCellStyleSelector, but what I think I need is one for a property that does not exist in the API:  GridViewColumn.FooterCellStyleSelector...

How should I proceed?

Kind Regards,
Albert

Hello Albert,


I have prepared a sample project that you can find attached. It shows you a possible approach for achieving the desired functionality.

I hope this is what you need.

Hello Yoan,

Thanks for the reply. I see that you are handling the RadGridView.AutoGeneratingColumn event to achieve the "GridViewColumn.FooterCellStyleSelector" type of behaviour I need.

The grid I am working on has AutoGenerateColumns="False". Can you recommend another event to handle, please?

Kind Regards,
Albert

Hello Albert,

In this case you can handle the CellEditEnded event:

private void clubsGrid_CellEditEnded(object sender, GridViewCellEditEndedEventArgs e)
        {
            this.clubsGrid.Columns["StadiumCapacity"].Footer = ((DataTemplate)this.Resources["ss"]).LoadContent();
        }

Hello Albert,

Just a quick update - Actually, you can apply the Footer's style right after InitializeComponent() :

public MainWindow()
       {
           InitializeComponent();

           this.clubsGrid.Columns["StadiumCapacity"].Footer = ((DataTemplate)this.Resources["ss"]).LoadContent();
       }

All the best,
