Question

I have some data. I want to go through that data and change cells (for example – Background color), if that data meets a certain condition. Somehow, I’ve not been able to figure it out how to do this seemingly easy thing in Silverlight.

Answer 1

This is slightly old code (from before RTM), but does something like what you’re looking for. It checks some data on an object in a row and then sets the colour of the row accordingly.

XAML:

<my:DataGrid x:Name='Grid' Grid.Row='1' Margin='5' GridlinesVisibility='None' PreparingRow='Grid_PreparingRow'>     <my:DataGrid.Columns>         <my:DataGridTextBoxColumn              DisplayMemberBinding='{Binding Cheese}'              Header='Cheese'></my:DataGridTextBoxColumn>         <my:DataGridTextBoxColumn              DisplayMemberBinding='{Binding Biscuit}'              Header='Biscuit'></my:DataGridTextBoxColumn>     </my:DataGrid.Columns> </my:DataGrid> 

Code:

this.Grid.AlternatingRowBackground = null;   private void Grid_PreparingRow(object sender, DataGridRowEventArgs e) {     CheesyClass c = e.Row.DataContext as CheesyClass;     if (c != null && c.Cheese == 'cheddar')     {        e.Row.Background = new System.Windows.Media.SolidColorBrush(System.Windows.Media.Color.FromArgb(255, 255, 125, 125));     } }
