datagridsilverlight
I'm using a DataGrid in Silverlight in ReadOnly mode. However, the DataGrid still allows selecting individual cells (changes background color and adds a thin blue border). I believe, the DataGrid is still turning the cell into a TextBox, but making it read-only.
I don't want the user to be able to select a single-cell, only a row. Is there anyway to accomplish this using the default Silverlight DataGrid?
Thanks,
Sergio
Here is my (lame) version that adds a black background on the selected row and grey background on the current row. I had to overwrite the styles because I was painting the cells individually and the row selected was hidden.
Just add the pasted code to you DataGrid instance:

This should get you started:-

Most of it is done by re-templating the DataGridCell. The inner border creates the rounded corners, while the outer border ensures there is a black background in the "space" around the rounded corners.
I've also added a trigger that sets the selected cell's background colour. The DataGrid is configured for single-cell selection - it looks like yours will be "Multiple".

There are a couple of solutions that i've seen, they all basically edit the style to prevent it from showing up like that.
