Custom Column background

[Andrew]

I have created a custom column that inherits from GridViewDataColumn and in my CreateCellElement I am trying to bind the cell's background to a color. I use the following code:  

public override FrameworkElement CreateCellElement(GridViewCell cell, object dataItem)

{

    InputChannelInfo channel = dataItem as InputChannelInfo;

 

    TextBlock tb = new TextBlock();

         ...

    Binding colourBinding = new Binding("ChannelColour");

        colourBinding.Source = channel;

        cell.SetBinding(GridViewCell.BackgroundProperty, colourBinding); 

    return tb;

}

This however doesn't work; what happens is that the cell loads but the background remains white. When I use the GridViewCell's Loaded event and do the backgound binding there it will work and the background changes. However I am trying to avoid this way for other reasons. Is there a way to get the cell's background to change when doing the binding in CreateCellElement?

Hello,

 Indeed, the initial Background for the Cells cannot be set like so. You could set the Background for the entire column instead.

How can you set each cells background separately ?

Hello,

 To set the background per cell, I would suggest you to define a CellStyleSelector for the column.
